Privacy
Applies to every game on games.8cross8.com and to our Android apps that wrap them. Last updated 18 August 2026.
The short version
- No accounts, no sign-in. You never give us your name, email or any personal detail.
- No cookies. We don’t use cookies or advertising or tracking identifiers, so there is nothing to consent to.
- Your progress stays on your device. Streaks, statistics and settings are stored in your browser’s local storage. Clearing site data removes them; a backup code (in each game’s statistics screen) lets you move them yourself.
- Anonymous usage counts only. To see how many people play and how hard the puzzles are, we count events such as “a puzzle was started”, “solved on Hard with 3 backtracks in 2 minutes” or “shared”. These counts contain no identifier and cannot be linked to you.
What is collected, exactly
We run our own copy of Umami, an open-source analytics tool, on our own servers. Nothing is sent to third-party analytics or ad companies. For each visit it records:
- page viewed, referrer (the site you came from, if any), country and browser/device type;
- anonymous game events (game, puzzle number, level, result, number of backtracks, time taken, whether the result was shared, and a coarse streak bucket such as “7–29 days”).
Your IP address is used only to derive the country and to group page views into a single visit for the current day; it is never stored. Umami’s own telemetry to its makers is switched off.
Optional features
- Sharing. The share button builds a short text (your result and a link) that you may paste anywhere. Nothing is sent by us.
- Chess Brick leaderboard. If you choose to submit a score, the nickname you type and your score are stored on our server so others can see the ranking. Don’t use your real name if you don’t want it shown.
- Android apps. When we publish Play Store versions, they are thin wrappers around these web pages and collect nothing beyond what is described above (Play data-safety: no personal data collected, no data shared).
Children
The games are suitable for all ages and collect no personal information from anyone.
