Privacy Policy
Each service handles different data, so each has its own privacy policy. Select a service below to see what it collects and how it processes data.
Common Principles
No accounts created
All services work without sign-up or login. We do not collect names, emails, phone numbers, or payment methods, and do not request social login or access to contacts, photos, or location.
Data sent only when you choose
Submitting to the leaderboard is optional. Only when you type a nickname and press the submit button are your nickname, score, and anonymous identifier sent to the server. If you don't press submit, nothing is transmitted.
Original IP addresses are not stored
To prevent spam and automated submissions, we hash your IP address with a server-side secret using SHA-256. Only the hash is stored; the original IP is never saved and cannot be recovered from the hash.
Progress stays on your device
Puzzles in progress, statistics, and settings like theme preference are stored only in your browser's localStorage. Clearing browser data removes them instantly. The operator cannot access these values.
