Privacy Policy
Catan Trainer & the Colonist Capture extension · Last updated July 24, 2026
Catan Trainer ("we", "us") helps you review your opening settlement placements in games of Catan. This policy explains what the Catan Trainer website and the Colonist Capture browser extension collect, how it is used, and the choices you have. By using them you agree to this policy.
What we collect
- Game data from your completed colonist.io games. When you finish a base game, the extension reads and uploads the board layout (hexes, numbers, ports), your two opening settlement and road placements, your in-game color, and the final result. It only captures your own completed games — never live play, other players' private information, or chat.
- Account information. To use Catan Trainer you sign in with an email address through our authentication provider. The extension stores a short-lived pairing token locally in your browser to link captured games to your account.
- Basic app usage needed to operate the service (e.g. timestamps of when a game was captured).
We do not collect payment information, precise location, browsing history, health data, or your personal communications.
How we use it
- To show you each captured game and feedback on your opening placements.
- To generate written analysis of your placements.
- To operate, secure, and improve the service.
We do not sell your data or use it for advertising.
Who we share it with (service providers)
We share data only with the processors needed to run the service, under their own terms:
- Supabase — authentication and database storage of your account and imported games.
- Anthropic — your board and placement data is sent to Anthropic's Claude API to generate placement analysis. It is not used to train their models under our API terms.
- Vercel and Render — website and backend hosting.
- PostHog — product analytics (pages visited within Catan Trainer and feature usage, tied to your account id). No session recording.
Data retention & your choices
- Imported games are kept until you delete them or delete your account. You can delete any imported game from "My games" on the site.
- You can remove the extension at any time from your browser; this stops all capturing and clears its locally stored pairing token.
- To request deletion of your account and associated data, contact us at the email below.
Security
Data is transmitted over HTTPS and stored with our hosting and database providers. No method of transmission or storage is perfectly secure, but we take reasonable measures to protect your information.
Children
Catan Trainer is not directed to children under 13, and we do not knowingly collect their data.
Changes
We may update this policy; material changes will be reflected by the "Last updated" date above.
