Who we are
Pixel Pawns is a chess app made by Pixel Haven. This policy explains what information the app uses, why, and how you can delete it.
Playing on your device
Games against the built-in bots, lessons, hints from the local coach and your settings stay on your device. Nothing is sent to us when you play offline.
Online and ranked play
When you first play online, the app creates an online profile on our server. It holds a display name, a random install ID the app makes up (not your phone's hardware ID), and the games and moves you play online.
If you create an account for Ranked Matches, we also keep your username, your password (stored only as a secure one-way hash), your rating and your wins, losses and draws. Your username and rating appear on the leaderboard and to the players you meet.
We use this information only to run online games, matchmaking, ratings and sign-in. Please do not use your real name as your username.
AI Rival
Some Ranked Matches opponents are AI Rival bots powered by a generative AI service from Anthropic. For each move, our server sends Anthropic only the chess moves of that game: which colour the bot plays, your last move and the moves the bot can choose from. We never send your name, username, ID or any other personal information.
If you report a message from an AI Rival, we store the reported message and the game it came from so we can improve safety.
AI Coach with your own key
If you add your own API key for an AI provider in Settings, the app sends the board position and the coach's notes directly from your device to that provider to improve hints and reviews. These requests do not go through Pixel Haven, and the provider's own privacy policy applies. Your key is kept in your device's secure storage and you can remove it at any time.
What we don't do
Pixel Pawns has no ads and no analytics or tracking tools. We do not sell or share your information, and we do not collect your location, contacts, photos, email address or phone number.
Security
The app talks to our server over encrypted connections (HTTPS). Passwords are hashed, and signing out or deleting your account ends your sessions on every device.
Keeping and deleting your data
We keep your online profile until you delete it. To delete it, open Player account in the app and tap Delete account (or Delete my online data if you have not made an account). This erases your username, password, display name, install ID, rating and results, and resigns any game in progress.
Finished games stay in your opponents' history, with you shown as "Deleted player". If you can no longer open the app, email us from the address below with your username and we will delete the account within 30 days.
Children
Pixel Pawns is made for players of all ages, including children. We only collect what online play needs, and nothing that identifies a child in the real world unless they type it into a username. Parents can ask us to delete a child's account at any time.
Changes and contact
If this policy changes, we will update the date below and the copy in the app. Questions or deletion requests: [email protected], or use the contact page at pixelhaven.mv.
