Last updated 1 September 2026
Lion Runner does not collect personal data. There is no account system, no analytics script, no advertising and no tracking cookie. The game runs entirely in your browser.
What is stored on your device
The game saves your progress using your browser's localStorage. This never leaves your device and is not readable by us or by any third party.
| Key | What it holds |
|---|---|
| lionrunner:stats | Best score, best distance, total coins collected and number of runs played. |
| lionrunner:leaderboard | Up to ten saved runs: the nickname you typed, score, distance, coins and the date. |
| lionrunner:nickname | The last nickname you entered, so the field is prefilled. |
| lionrunner:audio | Whether sound effects and music are switched on. |
| lionrunner:tutorial | Whether you ticked "don't show again" on the first-time tutorial. |
Nicknames
A nickname is optional and is only used to label a row on your own local leaderboard. It is stored on your device and never transmitted. Please don't type anything you would consider personal - it serves no purpose beyond a label on a table you alone can see.
Cookies
None are set. The site uses no cookies for any purpose, including analytics and advertising. See the cookie policyfor the detail, including what would change if advertising is switched on later.
Third-party services
The game loads no third-party scripts, fonts or media at runtime. Sounds and graphics are generated in the browser. Your hosting provider may keep standard server access logs, which are outside this site's control.
Offline caching
If your browser supports it, a service worker caches the game's own files so it can be played offline. This cache holds only site assets - no personal data - and is removed when you clear site data or uninstall the app.
Deleting your data
Use the "Clear this browser's scores" button on theleaderboard, or clear site data for this domain in your browser settings. Either removes everything listed above immediately and permanently.
Children
The game is suitable for all ages and collects nothing from anyone, so no age-specific data handling applies.
