Common issues

The board in my photo was read incorrectly

Shoot from directly above in good, even light, and make sure all four corners of the board are in frame. Then adjust the corner handles before recognition. You can fix any misread square with a tap before you analyze.

Analysis says it's using the offline engine

The app couldn't reach our engine server, so it switched to the built-in engine. That one is a little weaker but works anywhere. Check your connection and try again. Online analysis will resume on its own.

The camera or photo picker won't open

On iOS, go to Settings → BlackNWhite and allow Camera or Photos access. On Android, the app uses the system camera and photo picker, so make sure a camera app is installed and enabled.

Delete your data

BlackNWhite has no accounts, and we don't store your games, positions or photos on our servers. Everything the app keeps is on your device, so you're in control of deleting it:

  • Android: Settings → Apps → BlackNWhite → Storage → Clear storage, or uninstall the app.
  • iOS: press and hold the app icon → Remove App → Delete App.
  • Web: in your browser's settings, clear site data for game.blacknwhite.io.

Beta-list email: use the unsubscribe link in any of our emails, or emailsupport@airizz.co with the subject “Delete my data” from the address you signed up with. We'll delete it within 30 days and confirm by reply.

Short-lived server logs, such as IP addresses used for rate limiting, are deleted automatically within 30 days. Details are in our Privacy Policy.

To help us fix a bug quickly, please include:

  • the app version (Settings → About in the app);
  • what you did, what you expected, and what happened instead; and
  • if it's about a position, the game PGN (copy it from the Simulate screen) or a screenshot.
