Privacy policy

Last updated 12 November 2026

We keep things simple: we collect only what we need to run PuzzleRook and save your progress.

What we collect

  • Account details: email address, username, display name and a securely hashed password.
  • Progress: puzzles attempted, moves, hints used, time spent actively solving, ratings, streaks and rewards.
  • Settings: your time zone (so the Daily Gambit resets at your midnight) and preferences.
  • Technical data: IP address for security and rate limiting, kept only briefly.

Cookies

We use one essential, secure cookie to keep you signed in. We do not use advertising or tracking cookies today. If we add advertising in future, we will update this policy and ask for your consent where required.

Who processes data for us

  • Cloudflare (website hosting and network security).
  • Supabase (database and sign-in), hosted in Japan.
  • Google Gmail (sending password-reset emails).

We never sell your personal information.

Young players

PuzzleRook is designed for students. If you are under 13 (or the age of digital consent where you live), please ask a parent or guardian before creating an account. Parents can contact us to review or delete their child’s account.

Your choices

You can ask us to access, correct or delete your data at any time by emailing supportpuzzlerook@gmail.com.

Security

Passwords are hashed, connections are encrypted and access to data is restricted. No system is perfect, so please use a unique password.
