What stays on your device
Your settings, your streak, the puzzle you are playing and the date you first opened the game are kept in your browser's local storage. They are not sent anywhere.
What we count
To see whether the game is worth improving, it sends a few anonymous events. Each one only adds 1 to a total for that day:
- the game was opened, with the number of days since this device first opened it, and whether it runs on the web, in the Android app or on a games site;
- today's puzzle was started, or solved, with the number of hints and the time rounded to a range (under 5 minutes, 5 to 15, 15 to 30, or over 30);
- a result was shared, and whether by the share sheet or by copying;
- a practice puzzle was started, with its difficulty.
No IP address, browser details, device ID or any other personal data is stored with these totals. The counts cannot be linked to you, or to each other.
Clearing your data
To remove everything the game keeps on your device, clear this site's data in your browser settings. Your streak will reset.
