Last Updated: November 13, 2025
This End-User License Agreement (the "Agreement") is a legal contract between (i) the person or entity that accepts it (the "Licensee") and (ii) Woodhead SAS, a French société par actions simplifiée registered with the RCS of Poitiers under SIREN 992 285 528, having its registered office at 17 Rue du Maquis, 86000 Poitiers, France (the "Licensor"). If Licensee is an entity, the individual accepting represents and warrants that they have authority to bind that entity. Licensee shall ensure that its Affiliates and Authorized Users comply with this Agreement. The Licensor may be replaced by a Successor Licensor under §2.2 and §16.
The software known as "Natsura" is owned by George Hulm and Feike Postmes (the "IP Owners"). The IP Owners appoint the Licensor to grant end-user licenses, collect payments, provide support, and enforce this Agreement on their behalf. The Licensor represents and warrants that it has and will maintain such authority. Ownership of Natsura remains with the IP Owners.
By clicking "accept," installing, or using the Software, Licensee agrees to this Agreement. If you do not agree, do not install or use the Software. If the individual accepting lacks authority to bind an entity, they agree to be personally responsible until an authorized entity ratifies this Agreement. Key defined terms appear in §1.
"Activation Service" — the online licensing service used by Licensor for activation, validation, and enforcement (currently Keygen).
"Affiliate" — any entity that directly or indirectly controls, is controlled by, or is under common control with a party, where "control" means (a) ownership of more than 50% of voting securities; or (b) the right to appoint a majority of directors/management or otherwise direct material business decisions.
"Authorized User" — an employee or Contractor of Licensee, authorized by Licensee to use the Software solely on Licensee's behalf and bound by written terms no less protective than this Agreement (including confidentiality and IP assignment relevant to the Software).
"Blackboxed Components" — encrypted, compiled, obfuscated, or license-protected parts of the Software (including HDAs, VEX, OpenCL, Python modules, Qt interfaces, compiled plug-ins, Unreal plug-ins and .uasset files, and marked example files) that are not intended to be accessed, modified, or reverse-engineered.
"Commercial Use" — any use for, in support of, or in expectation of compensation or other consideration, including ad-monetized content, sponsorships, gratuities, non-cash benefits, or barter, whether direct or indirect.
"Competitor" — any third party whose primary business line includes tools for foliage/vegetation creation or materially substitutable procedural-generation technology. "Primary business line" means a product/service line generating ≥25% of annual revenue or promoted as a flagship offering.
"Computer" — a single physical or virtual machine instance. For cloud images, each VM/instance (including any clone of a golden image) is a distinct Computer and requires a unique activation; carrying an activation across images is prohibited.
"Contractor" — an individual or entity engaged by Licensee to provide services to Licensee, under confidentiality obligations and at all times under Licensee's direction and control. To the extent permitted by law, outputs created by a Contractor in connection with the Software are assigned to Licensee.
"Customer Assets" — works you create using the Software (e.g., 3D models, textures, materials, meshes, rigs, graphs, renders). Customer Assets exclude Toolkit Components and Regeneration-Enabling Artifacts.
"Derived Dataset" — a dataset whose primary value (≥50%) is substantially composed of Customer Assets or artifacts generated by the Software, including curated collections thereof intended for model training or evaluation.
"Device Seat" — a Seat assigned to one Computer (not user-bound).
"Extension" — a plug-in, script, preset, template, or integration developed by Licensee that interoperates with the Software, provided it (i) does not include, copy, expose, or rely on Toolkit Components or Blackboxed Components; (ii) does not enable use of the Software without a valid license; and (iii) does not bypass licensing/activation.
"Fiscal Year (FY)" — Licensee's last completed accounting year; if none, the trailing twelve months (TTM). FX: Non-USD figures are converted using the European Central Bank daily reference rate published on the FY close date (or TTM end).
"Funding" — capital available to Licensee's business from equity, debt, grants, advances, crowdfunding, including committed but undrawn amounts and non-dilutive financing.
"Headless/Worker Seat" — a Seat used solely for non-interactive batch, render, or simulation by or for the same Licensee (see §4.7).
"Host DCC" — SideFX Houdini and any supported third-party host into which the Software integrates, including Houdini Engine sessions (e.g., in Unreal Engine).
"Intermediate Files" — non-final computational artifacts intended for rendering, simulation, or downstream processing and not directly usable by end users without the Software (e.g., sim/scene caches, USD/IFD-like exports linked to Natsura graphs, graph caches). A USD or similar file that is directly usable in a DCC/game engine without Natsura and does not include Regeneration-Enabling Artifacts is treated as a Packaged Asset.
"License Models / Tiers" — Apprentice, Indie, Pro, Studio, Enterprise.
"License Server" — a network/floating licensing service. The Software does not support a License Server.
"Major Release" — a new version identified by a change in the first numeral of its version number (e.g., 2.0 succeeding 1.x). Minor updates, patches, and maintenance releases within the same major version are not Major Releases.
"Merchant of Record" — the authorized payment intermediary responsible for processing transactions, issuing invoices/receipts, and handling applicable taxes, chargebacks, or refunds on behalf of the Licensor. The Merchant of Record acts as the seller of record for payment purposes only and does not grant licenses or provide support under this Agreement.
"Model Training Activities" — training, pre-training, fine-tuning, or evaluation intended to improve models; dataset creation; synthetic data generation intended for model improvement; self-supervised learning; or any activity where Customer Assets or artifacts generated by the Software are used to produce or improve a model, including evaluation that updates model weights.
"Non-Commercial Use" — any use that is not Commercial Use, and that excludes ad-monetized content, sponsorships, or barter.
"Packaged Asset" — an end-user-consumable asset (e.g., meshes, rigged meshes, geometry rigs for DCC/game engines, textures, materials, runtime graphs) that does not include Toolkit Components or Regeneration-Enabling Artifacts.
"Payments Domain" — the portion of the customer relationship managed by the Merchant of Record, including payment processing, invoicing, refunds, chargebacks, and applicable sales or value-added taxes.
"Regeneration-Enabling Artifacts" — source graphs, node networks, presets, templates, caches, or metadata produced by or primarily for the Software that, when imported into Natsura, materially enable re-creation, regeneration, or parametric modification of a Customer Asset without independent creative effort. Packaged Assets are not Regeneration-Enabling Artifacts.
"Seat" — a right to activate and use the Software consistent with the applicable User Seat, Device Seat, or Headless/Worker Seat profile and associated limits.
"Software" — the Natsura plug-ins, Houdini Digital Assets (HDAs), VEX code, OpenCL code, Python code, Qt interfaces, example geometry and textures, JSON or other data files, optional Unreal plug-ins and .uasset files, presets, templates, graphs, scripts, updates, and related materials designed to run within a Host DCC. The Software is not a standalone application.
"Substantially Similar Model" — an AI/ML model whose primary purpose is to generate or procedurally construct foliage/vegetation assets or runtime graphs that are materially substitutable for core Natsura functionality (asset generation and parametric graph construction).
"Successor Licensor" — any affiliate or third party (including a joint venture owned by the IP Owners) to whom the Licensor assigns or delegates its licensing, support, payment, or enforcement duties for the Software.
"Toolkit Components" — any part of the Software or extensions for it, including nodes, operators, graphs, presets, templates, scripts, plug-ins, header files, or SDK elements.
"User Seat" — a Seat assigned to one named Authorized User and activated on one Computer at a time.
"Visible Components" — intentionally unencrypted HDAs and example files shipped with the Software that are provided for learning and integration and may be inspected and modified as permitted in this Agreement.
2.1 Ownership. The IP Owners retain full ownership of all intellectual property in the Software. All rights not expressly granted to the Licensee under this Agreement are reserved by the IP Owners.
2.2 Authority; Successor Licensor. The IP Owners appoint the Licensor to grant licenses, set prices, collect payments, provide support, and enforce this Agreement on their behalf. Licensee irrevocably consents in advance to the substitution of a Successor Licensor designated by the IP Owners or the Licensor. Upon written notice under §24, all references to "Licensor" in this Agreement shall be deemed to refer to the Successor Licensor as of the effective date in the notice, and the Successor Licensor assumes the Licensor's rights and obligations going forward.
3.1 License. Subject to payment and compliance, the Licensor grants Licensee a non-exclusive, non-transferable, non-sublicensable license to install and use the Software within a supported version of the Host DCC (including via Houdini Engine) to produce Customer Assets, within the applicable Tier and Seat limits. The Software is not a standalone application.
3.2 Installations & Movement (rolling 365 days).
3.3 Non-Concurrent Use. Interactive components may be used by one Authorized User on one Computer per Seat at a time. The Software does not support a License Server or floating/network licensing.
3.4 Cloud Instances. Node-locked installs are permitted on cloud VMs. Each VM/instance (including any clone of a golden image) requires a unique activation bound to a per-instance fingerprint. Carrying an activation across cloned instances is prohibited. No pooling or sharing. The Software relies on the Activation Service and does not provide an on-premise License Server.
3.5 Activation & Connectivity. Initial activation and ongoing use of the Software require Internet access to the Activation Service. The Software will periodically, and may continuously, contact the Activation Service to validate Licensee's license status and enforce Seat limits. If the Software cannot reach the Activation Service for a period determined by the Licensor (including due to network, firewall, or service issues), functionality may be reduced or disabled until connectivity is restored and the license is revalidated. Offline activation and fully offline use are not supported at this time. If online activation services are permanently discontinued, the Licensor will use commercially reasonable efforts to provide a workable path for compliant perpetual licensees of the affected Major Release (for example, escrowed offline keys or a final "offline build"), but does not guarantee any particular solution.
3.6 Location of Use. Use occurs where the Computer is physically located or, for cloud instances, where the compute resources run.
3.7 Seat Caps & Floating. Seat caps and eligibility are defined per Tier in §4. Floating or network licensing is not permitted unless expressly provided under a separate written agreement.
3.8 Reassignment (rolling 365 days).
3.9 Contractors. Licensee may permit Contractors to use Seats solely to provide services to Licensee. Licensee remains responsible for their compliance. Contractors may not set up or operate a License Server.
Single-Tier Rule. Licensee must select one Tier that applies to all Seats (Interactive and Headless/Worker) across Licensee and its Affiliates. Node-locked only; no License Server. Use is limited to supported Host DCC versions (including Houdini Engine).
4.1 Apprentice (Free; Non-Commercial). Non-Commercial Use only. Maximum 1 Seat. Node-locked only. No SLA.
4.2 Indie (Revenue or Funding < USD 100,000). Commercial use permitted. Updates included during an active subscription. Standard support. Up to 3 Seats total. Thresholds measured on a consolidated basis across Licensee and Affiliates against the higher of last FY or TTM.
4.3 Pro (USD 100,000–1,000,000). Commercial use permitted. Updates with active subscription. Standard support. Up to 3 Seats total. Thresholds measured as in §4.2.
4.4 Studio (Revenue or Funding ≥ USD 1,000,000). Commercial use permitted. Updates with active subscription. Priority support (faster SLA). Up to 6 Seats total. Thresholds measured as in §4.2.
4.5 Enterprise (Custom). For organizations requiring more than 6 Seats, bespoke SLAs, service-provider rights, or other custom terms. Custom pricing and terms apply. Headless/Worker Seats count toward Seat caps.
4.6 Tier Compliance. Thresholds apply on a consolidated basis across Licensee and Affiliates, measured against the higher of last FY or TTM (see §1). Headless/Worker Seats count toward Seat caps. If Licensee crosses a Tier threshold or exceeds a Seat cap, it must upgrade within 30 days. The Licensor may request reasonable proof of eligibility. For Indie, the Licensor may request proof only for cause.
4.7 Headless/Worker Seats. Permitted only for non-interactive batch, render, or simulation use by or for the same Licensee within a supported Host DCC (including Houdini Engine). Each instance is node-locked and requires its own Seat; the same Seat may not be used concurrently for interactive work. Headless/Worker use may not be provided as a service to third parties or used to power any third-party-facing content-generation or world-generation service, except under a separate written agreement with the Licensor.
5.1 Payment Models.
All fees are exclusive of taxes. Licensee is responsible for all taxes, duties, and withholdings (other than taxes on Licensor's net income).
5.2 Merchant of Record; Paddle Terms Control. All purchases are processed by Paddle (the Merchant of Record) under its Buyer Terms (available on Paddle's website). Within the Payments Domain (including payment processing, invoicing, refunds, chargebacks, and taxes), Paddle's Buyer Terms govern in the event of conflict with this Agreement.
5.3 Payment Failure; Chargebacks; Refunds. If a payment fails, is reversed, or is charged back, the Licensor may suspend or revoke the affected licenses immediately. Refunds (if any) are determined by Paddle within the Payments Domain and may require deactivation. Licensor is not obligated to provide any refunds beyond those processed by Paddle. Licenses obtained via fraudulent or reversed transactions may be permanently revoked.
6.1 Ownership of Software and Outputs. All intellectual property in the Software remains with the IP Owners. Licensee retains ownership of Customer Assets and may use, sell, or distribute them, subject to third-party rights, applicable law, and §§6.2–6.6.
6.2 Packaged Assets. Indie, Pro, Studio, and Enterprise Licensees may create, monetize, and sell Packaged Assets produced using the Software, including as part of client work, games, films, and marketplace products, without owing any royalty or revenue share to the Licensor for such exploitation, provided that such assets do not include Toolkit Components or Regeneration-Enabling Artifacts and subject to §7.6 and §8.
6.3 Toolkit Components. Licensee may not sell, license, or distribute Toolkit Components, nor tools that copy, expose, materially depend on, or enable use of Toolkit Components, except under a separate written agreement with the Licensor.
6.4 Intermediate Files. Licensee may not sell or license Intermediate Files as a primary product to third parties. Transient transfer of Intermediate Files to a third-party render vendor is allowed only where the vendor (i) operates solely on Licensee's behalf, (ii) is bound by confidentiality, (iii) acquires no rights and does not retain or reuse the files, and (iv) deletes the files after completion.
6.5 Third-Party Rendering. Use with third-party renderers is allowed. Any Intermediate Files remain subject to this Agreement and must not be used to bypass license terms.
6.6 Extensions. Licensee may develop and distribute Extensions that interoperate with the Software within the Host DCC, provided they (i) do not include, copy, expose, or rely on Toolkit Components or Blackboxed Components; (ii) do not enable use of the Software without a valid license or bypass licensing/activation; (iii) clearly state they are not endorsed by the Licensor; and (iv) comply with any published developer guidelines. The Licensor may withdraw permission for specific Extensions that materially impair security or licensing, or that enable use of the Software without a valid license.
6.7 Visible Components. The Licensor may provide certain HDAs or example files as Visible Components to illustrate integration with core Natsura tools. Licensee may inspect and modify Visible Components to build higher-level systems for its own use or as part of Packaged Assets, but may not (a) repackage or distribute the Software or any Blackboxed Components; (b) expose, copy, or recreate Toolkit Components; or (c) create a Substantially Similar Model or competing toolkit.
7.1 Reverse Engineering. Licensee must not reverse-engineer, decompile, disassemble, decrypt, or otherwise attempt to derive the Software's source code, underlying algorithms, data structures, asset formats, encryption, obfuscation, or license checks, including any Blackboxed Components, except to the limited extent expressly permitted by applicable law despite this restriction. For clarity, inspection and modification of Visible Components is permitted under §6.7.
7.2 Key Sharing and Redistribution. Licensee must not share, sell, transfer, sublicense, or otherwise distribute license keys, activation files, Seats, or any build of the Software to any third party except as expressly allowed in this Agreement. Embedding keys in public repositories, CI artifacts, or distributable images is prohibited.
7.3 Unlawful or Infringing Use. Licensee must not use the Software for any unlawful purpose or in a way that infringes the intellectual-property or other rights of any person.
7.4 Automated or Unauthorized Access. Licensee must not access or use the Software through automated systems, bots, or scripts except (i) as expressly supported by an official API, SDK, or documented Headless/Worker workflow, and (ii) within documented limits. Automation must not be used to bypass Seat limits, licensing, or other technical protections.
7.5 Circumvention. Licensee must not circumvent or attempt to disable copy-protection, usage, or access-control mechanisms.
7.6 Resale or Hosting; Service-Provider Use. Licensee may use the Software to produce Customer Assets and deliver them to clients as part of Licensee's own services, provided only Licensee and its Authorized Users operate the Software. Licensee must not host, lease, or provide the Software, or any automated system, pipeline, or platform that uses the Software, in a way that allows third parties (including Licensee's customers) to directly or indirectly generate, customize, or regenerate content by means of the Software, unless expressly authorized in writing by the Licensor (for example, under an Enterprise order or a separate service-provider or AI Use License).
7.7 Export Control. Licensee must comply with applicable export-control and sanctions laws (including EU, UK, and U.S. regimes) and must not use the Software in any country or by any person or entity prohibited under those laws. Licensee shall notify Licensor immediately if it becomes aware of any restricted use.
7.8 Other Prohibited Conduct. Licensee must not remove proprietary notices, branding, or watermarks; interfere with license-enforcement systems; or misrepresent the origin of outputs created with the Software.
7.9 Tampering & Integrity. Licensee must not modify, patch, hook, stub, or otherwise tamper with the Software, its license checks, its calls to the Activation Service, or any Blackboxed Components; must not remove or alter digital signatures, watermarks, or proprietary notices; and must not use debuggers or tracers to intercept or bypass licensing or runtime protections.
8.1 AI Use License Required for Model Training Activities. Without Licensor's prior written agreement (an "AI Use License"), Licensee shall not use the Software, Customer Assets, or Derived Datasets for Model Training Activities or to create, sell, publish, or distribute Derived Datasets.
8.2 Inference & Private QA Allowed; Third-Party AI Tools. Use of models for inference on Customer Assets is permitted. Private, internal evaluation/QA that does not produce a dataset or model offered to third parties is permitted. Inference may occur within the Host DCC or externally, provided it does not use the Software, Customer Assets, or Derived Datasets to create or improve models without an AI Use License. For clarity, this Section 8 does not restrict Licensee's use of third-party AI tools or services that were not trained or fine-tuned using the Software, Customer Assets, or Derived Datasets by or on behalf of Licensee in breach of §8.1.
8.3 No Substantially Similar Model (Limited Non-Compete). To the maximum extent permitted by law, during the Term and for 24 months thereafter, Licensee shall not use the Software, Customer Assets, or Derived Datasets to develop or train a Substantially Similar Model for commercial distribution to third parties. This §8.3 does not restrict independent development without use of the Software, Customer Assets, or Derived Datasets, nor in-house models used solely to deliver Licensee's own services without distribution, provided such development otherwise complies with §8.1 and §7.6.
8.4 Relief. Breach of this Section would cause irreparable harm. The Licensor may seek injunctive relief in addition to other remedies.
8.5 Path to Compliance. Licensor may offer standard AI Use License terms (e.g., revenue share or fixed fee). Licensee must contact the Licensor for approval prior to any Model Training Activities.
The Software may collect limited pseudonymous technical data (e.g., license status, version, OS, device fingerprint, coarse performance/usage metrics) through the Activation Service to enforce licensing and improve functionality within the Host DCC. Personal data, if any, is processed according to Licensor's Privacy Notice (available in-app and on the website) and applicable law (including GDPR). Roles: the Licensor is controller; Keygen (licensing) is processor; Paddle is an independent controller for the Payments Domain. If the Licensor is replaced by a Successor Licensor, roles and processing responsibilities transfer accordingly, and Licensee will be notified under §24.
Lawful bases & purposes. The Licensor processes personal data on the lawful bases of legitimate interests, performance of contract, or legal obligation, including for licensing enforcement, fraud prevention, support and quality, payment processing (by the Merchant of Record), and legal compliance.
Choices. Non-essential telemetry can be disabled where provided in settings. Telemetry does not include Customer Assets or content and does not access Host DCC project files except as strictly necessary for licensing (e.g., host version and platform).
Retention & transfers. Technical data is retained for the minimum period necessary. Transfers outside the EEA use appropriate safeguards (e.g., SCCs). A list of sub-processors and a DPA is available on request.
10.1 Certification.
10.2 Audit. With 10 business days' notice (no more than once every 12 months unless for cause), the Licensor may conduct a remote audit limited to records reasonably necessary to confirm compliance. Auditors are bound by confidentiality and will use reasonable efforts to minimize business disruption. There shall be no on-device intrusive scanning; audits are remote and records-based (e.g., Activation Service logs, Seat assignments, purchase records).
10.3 Remedies. If a material variance (≥10%) is found, Licensee shall promptly (i) pay shortfalls and (ii) upgrade Tiers/Seats as needed. The Licensor may suspend licenses for unremedied material breach after a 30-day cure period.
The Software requires a valid, legally obtained installation and license of the applicable Host DCC (e.g., SideFX Houdini) and may include third-party libraries or open-source components under separate licenses, detailed in the "NOTICES" file or documentation. Those licenses govern their respective components. The Host DCC and any game engines (e.g., Unreal Engine) are not provided by the Licensor, and their licenses and terms are solely between Licensee and the relevant vendor.
12.1 Support Levels. Support services are provided according to the Support Level applicable to Licensee's plan, as set out in the Support Policy or Schedule 2 (Support Levels), on a commercially reasonable efforts basis. Support covers installation, activation, configuration, and general use of the Software within supported Host DCC versions as published by the Licensor; issues arising from unsupported Host DCC versions, custom builds, or modified Blackboxed Components are out of scope. On transition to a Successor Licensor, open support requests and entitlements will be assumed and honored through the remainder of the paid term.
12.2 Updates. Subscription and perpetual licenses include updates as specified in your plan. The Licensor is not obliged to provide future updates beyond those terms. Compatibility updates target supported Host DCC versions only.
The Software is provided "as is" and "as available." To the maximum extent permitted by law, the Licensor and the IP Owners disclaim all warranties, whether express or implied, including merchantability, fitness for a particular purpose, and non-infringement. No advice or information provided by the Licensor, its employees, or partners shall create any warranty or obligation not expressly stated in this Agreement.
To the maximum extent permitted by law, the Licensor and the IP Owners shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, or business. The total liability under this Agreement will not exceed the amount paid for the Software in the twelve (12) months preceding the event giving rise to the claim. Nothing in this Agreement excludes or limits liability that cannot be excluded by law, including for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation.
15.1 Duration. This Agreement remains in effect until terminated, or for subscription licenses, until the end of the paid term.
15.2 Termination for Cause. The Licensor may suspend or terminate immediately for willful misconduct (including piracy, fraud, deliberate circumvention, or unauthorized redistribution). For other breaches, Licensee will have thirty (30) days to remedy after notice.
15.3 Payment Reversal. Upon chargeback or payment reversal, the Licensor may suspend or terminate the affected licenses immediately. Refunds, if any, are determined by the Merchant of Record.
15.4 Effect of Termination. Upon termination or expiry, Licensee must stop using the Software and delete all copies, except for any perpetual licenses that remain valid in accordance with §18 (Survival and Perpetual Viability). Customer Assets created before termination remain Licensee's property. Termination does not affect accrued payment obligations or any rights or obligations that, by their nature or under §18, survive termination.
Licensee may not assign or transfer this Agreement without Licensor's prior written consent, except to a successor in a bona fide merger, reorganization, or sale of substantially all assets, provided the successor is not a Competitor and agrees in writing to be bound by these terms; consent will not be unreasonably withheld, conditioned, or delayed. The Licensor may assign or delegate its rights and obligations (in whole or in part) to its affiliates, to the Merchant of Record with respect to the Payments Domain, or to a Successor Licensor, by written notice under §24. From the effective date of such notice, references to "Licensor" mean the Successor Licensor.
Neither party will be liable for any delay or failure to perform its obligations under this Agreement to the extent caused by events beyond its reasonable control, including natural disasters, war, civil unrest, labor disputes, power or Internet failures, or government actions. Performance will be suspended for the duration of the event and resume once the cause has ceased.
18.1 Survival. Sections 1–2, 6–9, 12 (to the extent of accrued obligations), 13–15, and 20–25 survive termination.
18.2 Perpetual Viability (No Guaranteed Offline). Perpetual licenses are terminable only for material breach under §15. Offline activation is not guaranteed. If online activation is permanently discontinued, the Licensor will use commercially reasonable efforts to provide a workable path for compliant perpetual licensees of the affected Major Release.
Each party will comply with all applicable export-control and sanctions laws. Breach of the export obligations in §7.7 will constitute a material breach of this Agreement. The Licensor may suspend or terminate this Agreement where required by such laws.
20.1 Changes. Licensor may modify the Software or this Agreement from time to time. Material changes will be announced via the Software, website, or direct email notice. Licensee's continued use after such changes take effect constitutes acceptance. For perpetually licensed versions, new terms apply only to updates Licensee chooses to install. For clarity, appointment of a Successor Licensor under §2.2 and §16 is not a change to this Agreement and does not require Licensee's further consent.
20.2 Severability; Waiver. If any provision is held unenforceable, the remainder remains effective. Failure to enforce any provision is not a waiver.
20.3 Entire Agreement. This Agreement (including documents referenced herein) is the entire agreement between the parties regarding the Software and supersedes any prior terms or representations. In case of translation discrepancies, the English version prevails (without prejudice to mandatory consumer protections).
20.4 Precedence. This Agreement governs over purchase orders or other documents for the Software. Within the Payments Domain, Paddle's Buyer Terms govern; in all other respects, this Agreement governs.
Licensee is responsible for safeguarding accounts, license keys, activation files, and device access. Prohibited: sharing accounts/keys, embedding keys in public repos or CI artifacts, or exposing activations in public images. Licensee shall promptly notify Licensor of suspected compromise and cooperate in mitigation, and must promptly rotate compromised keys/activations. Licensee must not publish, distribute, or include any activation tied to the Software in publicly shared VM or container images.
22.1 Benchmarks. Public benchmarking is permitted provided results are truthful, reproducible, disclose Software version, Host DCC version and edition, and hardware, and clearly state whether pre-release builds were used. Publication of pre-release results requires Licensor's prior written permission.
22.2 Publicity. Licensee may truthfully state that its assets or projects were "made with Natsura." Use of Licensor's names, logos, or trademarks beyond nominative fair use requires written permission and adherence to brand guidelines.
23.1 Licensee Indemnity. Licensee will defend and indemnify Licensor and the IP Owners against third-party claims arising from (i) Customer Assets, (ii) Licensee's breach of this Agreement, or (iii) use of the Software in violation of law. Indemnity is conditioned on prompt notice, reasonable cooperation, and Licensee controlling the defense (except that Licensor may retain its own counsel at its expense). Licensee may not settle a claim that imposes non-monetary obligations on Licensor without Licensor's prior written consent (not unreasonably withheld).
23.2 Vendor Indemnity (Optional; Enterprise only). If expressly agreed in an Enterprise order form, the Licensor will indemnify Licensee for third-party claims alleging that the unmodified Software infringes IP rights, subject to customary exclusions and remedies (e.g., modification, replacement, or refund of depreciated license fees). Indemnity is conditioned on prompt notice, reasonable cooperation, and Licensor controlling the defense.
Notices required under this Agreement must be in writing and may be sent by email or other electronic means to (i) the most recent contact address provided by Licensee through its account, and (ii) Licensor's published contact address for legal or licensing matters as shown in the Software or on its official website. Notices are deemed received when successfully sent, provided the sender retains proof of transmission (such as an email delivery log). For termination or breach notices, the sender will make reasonable efforts to confirm delivery (for example, by requesting a read receipt or sending a follow-up). A notice of change to a Successor Licensor is effective if sent to Licensee's last provided contact and/or posted in-product or on Licensor's official website, and will state the effective date and new contact, invoicing, and support details. The Licensor may also provide general product or policy notices through the Software or its official website.
This Agreement is governed by the laws of France.
Business Customers. Any dispute, controversy, or claim arising out of or relating to this Agreement shall be finally resolved by arbitration under the Rules of Arbitration of the International Chamber of Commerce (ICC). The seat of arbitration shall be Paris, France. The language of arbitration shall be English, and the English version of this Agreement is the authoritative text in all proceedings. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
Consumers (EEA/UK). Nothing in this Agreement deprives consumers of mandatory rights. For consumers in the EEA/UK, (i) the arbitration clause does not apply; (ii) you may bring claims in your local courts; and (iii) local consumer law (including any right of withdrawal for digital content where applicable) prevails in case of conflict. A French translation is available upon request.
If arbitration is deemed unenforceable for any party, disputes shall be subject to the exclusive jurisdiction of the courts of Paris, France, except where consumer law provides otherwise.

This Schedule forms part of the Agreement and sets out the general support levels for each license plan. Support is provided on a commercially reasonable efforts basis by a small team and is not a 24/7 service.
Unless otherwise agreed in writing (for example, in an Enterprise order form), support is provided via email and community channels during typical business hours (CET/CEST) on business days, excluding French public holidays and reasonable company shutdown periods.
The following timeframes are targets only, not guaranteed service levels. They describe what the Licensor aims for under normal conditions, but failure to meet them does not constitute a breach of the Agreement and does not give rise to credits, refunds, or other remedies beyond those set out in the Agreement.
Support covers:
