Privacy Policy

Last updated: October 22, 2026

Short version: no ads, no analytics, no trackers, no accounts, no cookies. We store only what the high-score leaderboard needs.

What we store on our server

Only when you choose to submit a score to the leaderboard:

• the nickname you type (or "Anonym"),
• your score and which game skin you played,
• the date and time,
• a one-way, salted hash of your IP address. We never store your IP address itself. The hash is used only to stop cheating and spam (for example, limiting how often scores can be submitted).

When a game starts on our full game pages, we also create a temporary run record (a random token, the same IP hash and the start time) so that we can check that submitted scores are realistic. Run records are deleted after 24 hours.

Like every web server, ours writes standard access logs (including IP addresses) for security and troubleshooting. These are kept for a short time and are not used to identify or profile players.

What stays in your browser

Your personal best score and the last nickname you used are saved in your browser's local storage so they are there next time. They never leave your device unless you submit a score. You can clear them by clearing your browser's site data.

Embedded games and classrooms

Games embedded on other websites (including school and LMS pages) do not submit scores and do not create run records. Nothing about players of embedded games is stored on our server, apart from the standard access logs described above.

What we do not do

• No advertising or ad networks.
• No analytics or third-party scripts.
• No cookies.
• No selling or sharing of data.

Children

The Site does not require any personal information to play. We do not knowingly collect personal information from children. Teachers and parents can ask children to use "Anonym" or a non-identifying nickname on the leaderboard.

Removing your data

To have a leaderboard entry removed, email [email protected] with the nickname, score and approximate date.

Changes

If this policy changes, we will update the date at the top of this page.
