Terms of Service

Last updated: 2026-05-07

These Terms of Service ("Terms") govern your use of Isometra ("the service"). By creating an account or using the service, you agree to these Terms. If you don't agree, don't use the service.

1. The service

Isometra is a 5E-compatible virtual tabletop for in-person and online tabletop roleplaying. It helps you run campaigns, build characters, manage sessions, and chat with optional AI personas. The service is provided as-is, free of charge for personal, non-commercial play. Features may change, be added, or be removed at any time.

Isometra renders rules content from one or more publicly licensed System Reference Documents (see Licensing & Attribution for the canonical attribution statement and license terms). Isometra is independent and is not produced, sponsored, endorsed by, or otherwise affiliated with the publishers of any roleplaying game system. Third-party trademarks remain the property of their respective owners; their occasional appearance in user-authored content (campaign names, character backstories, etc.) is the responsibility of the user under section 4 of these Terms.

2. Eligibility and accounts

• You must be at least 13 years old to use the service. If you are between 13 and the age of majority in your jurisdiction, you confirm you have your parent or guardian's permission.
• You must provide accurate information when creating an account.
• You are responsible for keeping your sign-in credentials secure. Don't share your account.
• One account per person. Don't impersonate others.

3. Acceptable use

You agree NOT to:

• Use the service for any unlawful purpose, or to violate the rights of others.
• Upload, post, or share content that is illegal, abusive, harassing, defamatory, sexually explicit involving minors, or that infringes the intellectual property of others.
• Attempt to break, probe, or interfere with the service's security, scrape it at scale, or use automated tools to overload it.
• Reverse-engineer the service except as expressly permitted by applicable law.
• Use the service to generate content that violates third-party platform policies — for example, prompting our AI features to produce content that violates Anthropic's Usage Policy or Google's generative-AI terms.
• Resell, rent, or sublicense access to the service.

We may, at our discretion, remove content or suspend accounts that violate these rules.

4. Content and licensing

Your content

You retain all rights to the campaigns, characters, NPCs, homebrew rules, and other content you create in Isometra ("Your Content").

By submitting Your Content to the service, you grant Isometra a worldwide, non-exclusive, royalty-free license to host, store, reproduce, display, and distribute Your Content as needed to operate the service (e.g. rendering it back to you, sharing it with collaborators you invite, processing it through our AI sub-processors when you use AI features).

Public/Discover content

If you publish a campaign to Discover, you additionally grant other Isometra users a license to view and fork that content, with attribution back to you preserved by the platform. You can unpublish at any time, but existing forks remain independent works (see Privacy Policy section 6).

Forking and attribution

When you fork another user's published campaign, you accept that:

• The fork is your own copy; you may modify it freely for your private play.
• The original creator's attribution is preserved on the fork in our system.
• Mass redistribution of forked content outside Isometra is your responsibility under applicable law.

Third-party SRD content

Isometra renders rules text from public SRD documents (currently SRD 5.1 and SRD 5.2.1) under the Creative Commons Attribution 4.0 International License. SRD content is not Your Content; it remains under its original license. See /about/licensing for full attribution and license details.

AI-generated content

Content generated by the in-app AI personas (Loremaster, Lyra) and AI helpers (NPC suggestions, portraits, session summaries) is yours to use within the service for your campaign. You are responsible for verifying its accuracy and ensuring its use complies with the AI provider's terms (Anthropic Usage Policy, Google's gen-AI terms via Vercel AI Gateway).

5. AI features

The AI features are provided "as-is." AI personas can produce inaccurate or out-of-character responses. Treat their output as a draft suggestion, not a substitute for the rulebook or your own judgment as a DM/player. We are not liable for in-game decisions based on AI output.

6. Payment

Isometra is currently free of charge. If we introduce paid plans in the future, we will give existing users notice and a clear opt-in before any charge.

7. Termination

• By you: delete your account at any time from Settings. See the Privacy Policy for what happens to your data.
• By us: we may suspend or terminate your account if you materially breach these Terms (e.g. repeated abuse, illegal use, security violations). Where reasonable and lawful, we will notify you and give you a chance to remediate.

These Terms survive termination to the extent needed to enforce remaining rights and obligations.

8. Disclaimers

The service is provided "as-is" and "as-available," without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not guarantee that the service will be uninterrupted, error-free, or that AI output will be accurate.

You use the service at your own risk.

9. Limitation of liability

To the maximum extent permitted by law, Isometra and its operators are not liable for indirect, incidental, special, consequential, or punitive damages, or loss of profits, revenue, data, goodwill, or other intangible losses, arising out of or related to your use of the service. Our aggregate liability for direct damages is limited to USD 100 or the amount you paid us in the prior 12 months, whichever is greater.

Some jurisdictions don't allow these limitations; in those places, our liability is limited to the maximum extent permitted by law.

10. Indemnification

You agree to defend and indemnify Isometra and its operators against claims arising from Your Content or your breach of these Terms, to the extent permitted by law.

11. Changes to these Terms

When we change these Terms materially, we will update the "Last updated" date and surface a notice in the app. Continued use after the effective date constitutes acceptance.

12. Governing law

These Terms are governed by the laws of the State of New York, United States of America, without regard to conflict-of-laws principles. Disputes will be resolved in the courts of that jurisdiction, except where mandatory consumer-protection law gives you the right to bring claims locally.

13. Miscellaneous

• If any provision of these Terms is unenforceable, the rest stays in effect.
• We may assign these Terms in connection with a merger, acquisition, or sale; we will notify you if we do.
• These Terms are the entire agreement between you and us regarding the service.
