Privacy Policy
Chess.ai · Effective date: May 5, 2026 · Last updated: May 5, 2026
Chess.ai ("we", "our", or "the app") is a chess game where you play against an AI opponent powered by Claude (Anthropic). This policy explains what data we collect, why, and how we handle it.
1. Data We Collect
- Anonymous device identifier — a randomly generated UUID created on your device at first launch. It is never linked to your name, email, or any personal information.
- Game data — chess moves and game history sent to our server to generate AI responses. This data is associated only with your anonymous ID.
- Purchase records — when you buy in-app credits, RevenueCat and Apple process the transaction. We receive a webhook confirming the purchase to credit your account. We do not store payment card details.
2. Data We Do NOT Collect
- Name, email address, or any contact information
- Location data
- Camera, microphone, or photo library access
- Contacts or social graph
3. How We Use Your Data
- To generate AI chess moves and conversational responses via the Anthropic Claude API
- To track your remaining free games and purchased credits
- To improve app stability and diagnose server errors (server logs, no personal data)
4. Third-Party Services
- Anthropic — your chess moves and conversation history are sent to Anthropic's API to generate AI responses. Anthropic's privacy policy: anthropic.com/privacy
- RevenueCat — handles in-app purchase tracking. RevenueCat's privacy policy: revenuecat.com/privacy
- Apple App Store — payment processing for in-app purchases. Apple's privacy policy: apple.com/legal/privacy
5. Data Retention
Game data on our servers is retained for as long as your account (anonymous ID) is active. You can request deletion at any time by contacting us at the address below — we will remove all data associated with your device ID within 30 days.
6. Data Storage & Security
Game history is stored locally on your device using SQLite. Server-side data is stored in a PostgreSQL database on a private server. We use HTTPS for all data in transit and follow industry-standard security practices.
7. Children's Privacy
Chess.ai does not knowingly collect personal information from children under 13. The app collects no personally identifiable information from any user, making it safe for all ages.
8. Your Rights
Because we only hold an anonymous device ID, there is no personal profile to access or correct. To delete all data tied to your device, contact us and provide your device ID (visible in app settings) and we will erase it.
9. Changes to This Policy
We may update this policy from time to time. The "Last updated" date at the top of this page will reflect any changes. Continued use of the app after changes constitutes acceptance of the updated policy.
