End User Licence Agreement

Last updated: 23 April 2026 · Version 1.0

IMPORTANT: Read this agreement carefully before installing or using the Software. By clicking "I Agree", installing, or otherwise using 2DSUITE, you agree to be bound by these terms. If you do not agree, do not install or use the Software.

This End User Licence Agreement ("Agreement") is a legal contract between you ("you", "user") and Djinja-C Limited, a company registered in England & Wales ("Djinja-C", "we", "us"), for your use of the 2DSUITE desktop application, Revit add-in, and related software (collectively, the "Software").

1. Grant of Licence

Subject to your compliance with this Agreement, Djinja-C grants you a limited, non-exclusive, non-transferable, revocable licence to install and use one copy of the Software on computers you own or control, for your personal or internal business use.

The scope of functionality available to you depends on your active subscription tier (Free, Pro, Studio, or Enterprise). Feature access is enforced by a signed licence code tied to your account.

2. Autodesk Revit Integration

The Software includes an optional Revit add-in ("TwoDSuiteBridge") that installs a ribbon tab in Autodesk Revit and launches the desktop application via a local inter-process bridge (a JSON file stored in your user profile).

The Revit add-in:

Runs entirely on your local machine;
Does not transmit Revit model data, project files, or design content to Djinja-C or any third party;
Operates via Revit's published IExternalApplication API and your installed Revit keyboard shortcut map.

Autodesk Disclaimer: Autodesk, Inc. is not a party to this Agreement, makes no warranties regarding the Software, and has no liability for any claim arising from your use of it. "Autodesk" and "Revit" are trademarks of Autodesk, Inc.

3. Restrictions

You agree not to:

Copy, modify, or create derivative works of the Software;
Reverse-engineer, decompile, or disassemble the Software, except to the extent this restriction is expressly prohibited by law;
Rent, lease, sell, sublicense, or redistribute the Software;
Remove or alter proprietary notices or labels;
Use the Software to develop a competing product;
Circumvent licence verification, tier gating, or session limits;
Use the Software in violation of any applicable law or regulation.

4. AI-Generated Content — No Professional Advice

The Software uses third-party AI models (including Anthropic Claude) to generate suggestions, code snippets, summaries, and technical guidance ("AI Output"). AI Output is provided on an "as is" basis and may contain errors, omissions, or inaccuracies.

You are solely responsible for reviewing, validating, and verifying all AI Output before relying on it in professional work. AI Output does not constitute engineering, architectural, legal, financial, or medical advice. Do not submit safety-critical outputs without independent professional review.

5. Third-Party Services

The Software integrates with the following third-party services. Your use of each is governed by their own terms:

Anthropic (Claude AI) — AI inference
LemonSqueezy — subscription billing (merchant of record)
Sentry — error / crash reporting (optional, can be disabled)
GitHub Releases — software updates

Where you supply your own API key (e.g. direct OpenAI or Anthropic key), billing and liability for that API usage is between you and the provider. Djinja-C is not a party to that arrangement.

6. Data Collection and Privacy

The Software collects limited data as described in our Privacy Policy, which forms part of this Agreement. In summary:

Account email, name, subscription status;
Anonymised usage telemetry (feature clicks, session duration);
Optional crash reports (Sentry);
No screen content, no Revit model data, and no project files are retained beyond the transient API call to the AI provider.

7. Subscription, Payment, and Refunds

Paid tiers are billed in advance via LemonSqueezy. You may cancel at any time; cancellation takes effect at the end of the current billing period. We do not offer pro-rated refunds for partial billing periods except where required by law.

If you purchase via the Autodesk App Store, refunds are handled by Autodesk in accordance with the Autodesk App Store refund policy.

8. Intellectual Property

The Software, its source code, design, trademarks, and all associated intellectual property rights are and shall remain the sole property of Djinja-C Limited.

Content you create or input while using the Software (project files, prompts, notes, documents) remains your property. We claim no ownership or licence over your content beyond what is strictly necessary to provide the Software's features.

9. Updates

The Software may automatically check for and install updates. Updates may add, modify, or remove features. Continued use after an update constitutes acceptance of the updated Software.

10. Warranty Disclaimer

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR UNINTERRUPTED OPERATION. WE DO NOT WARRANT THAT AI OUTPUT IS ACCURATE, COMPLETE, OR SUITABLE FOR YOUR INTENDED USE.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, DJINJA-C SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF DATA, PROFITS, OR BUSINESS INTERRUPTION, ARISING FROM OR RELATED TO YOUR USE OF THE SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Our total aggregate liability under this Agreement shall not exceed the greater of (a) the amount you paid us in the 12 months preceding the claim, or (b) £50 (GBP 50).

Nothing in this Agreement excludes or limits liability for death or personal injury caused by negligence, fraud, or any other liability that cannot be excluded by law.

12. Termination

This Agreement is effective until terminated. We may suspend or terminate your licence if you breach these terms. Upon termination you must cease all use of the Software and remove it from your devices. Sections 3, 4, 6, 8, 10, 11, 13, and 14 survive termination.

13. Governing Law

This Agreement is governed by the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.

14. Entire Agreement

This Agreement, together with the Privacy Policy and Terms of Service, constitutes the entire agreement between you and Djinja-C Limited regarding the Software, and supersedes all prior agreements or understandings.
