Does Wembuno use cookies?
No. Wembuno does not set any cookies, and there are no third-party cookies.
Local storage and offline cache
Instead of cookies, Wembuno uses your browser’s local storage and an offline cache. They are strictly necessary for the game to work, and their contents never leave your device.
| What is stored | Why | How long |
|---|---|---|
wembuno.save.v1 (local storage): game progress — results for each multiplication fact, level, coins, stars, achievements, items, settings and a daily activity summary for the last 120 days | To save progress, adapt questions to the facts your child finds hardest, and show the progress report | Until you reset progress or clear this site’s data |
wembuno.lang (local storage): preferred language | To open Wembuno in the language you chose | Until you clear this site’s data |
| Offline cache (service worker): copies of Wembuno’s own pages, styles and scripts | To load quickly and keep working with a poor connection | Replaced automatically when Wembuno updates |
How to delete stored data
- In the game: Settings → Grown-up zone → Reset all progress.
- In your browser: open the site settings for this website and choose to clear or remove its data.
