Privacy & game saves

Understand what the game saves in your browser and how to back up or delete progress.

Last updated October 2, 2026

Your game progress stays in your browser

Pocket Mutant Lab uses browser storage for your board, coins, collection, research progress and preferences. No game account is required. There are no cloud game saves, and progress does not automatically sync across browsers or devices.

Back up or delete your progress

Open Help & save from Supplies or Collection to export a JSON backup or choose a file to restore. Restoring replaces current progress; read the confirmation first. Clearing this website’s browser data removes local progress and preferences and may also sign you out of the creator’s garden. Export a backup first.

Website connections and technical logs

When you visit, the hosting server processes information needed to serve the site, such as your IP address, requested path, browser information and request time. Access and error logs may be retained for operation and troubleshooting. Game assets are served by this website. No third-party player analytics are currently installed.

Advertising status

This site has applied for Google AdSense. At present, only site-verification metadata and ads.txt are published. No advertising scripts, live ads or paid purchases are enabled. This notice will be updated before live advertising is introduced, with the required consent choices in applicable regions.

The creator’s garden is a separate feature

Accounts and private pages in the creator’s garden use separate authentication and server-side storage. They are not game registration pages. Public game pages do not read those private records.
