What we store

  • An anonymous player ID. The first time you finish a puzzle we create a random ID and keep it in a cookie called tt_pid(HTTP-only, one year). It isn't linked to your name, email or device details.
  • Your results.The difficulty, the puzzle's seed, your time, lives left, moves and the date, so we can build the leaderboard and count puzzles solved.
  • A display name, only if you add one.It appears on the public leaderboard, so don't use your real name if you'd rather not.

What stays on your device

Your streak, which Dailies you've finished and your sound and vibration settings are kept in your browser's local storage and never sent to us.
