Cookies and Similar Technologies

1. What are cookies and similar technologies?
Cookies are small text files stored on your device. Similar technologies include browser storage such as local storage, which can also remember settings between visits.
2. Our approach
My Little Hero is built with a privacy-first approach. We use only essential cookies and functional storage needed to run the product safely and remember usability settings.
We also use a small amount of browser local storage for accessibility and appearance preferences such as dark mode, font size, and dyslexia font settings. These are functional storage items that do not track you.
Because we use only essential cookies and functional storage, and do not use advertising, analytics, or tracking technologies, we do not show a cookie consent banner under PECR.
3. What we use
| Name | Purpose | Duration |
|---|---|---|
| XSRF-TOKEN | Essential: protects against Cross-Site Request Forgery (CSRF) attacks. | Session |
| mylittlehero_session | Essential: stores your encrypted session ID so the authenticated service works securely. | 2 hours |
| kid_session_token | Essential: authorises access to the sealed Kid Mode reader without a full account login. | 2 hours |
| classroom_access_token | Essential: grants pseudonymous access to a specific classroom bookshelf. | 8 hours |
| appearance | Functional: remembers your light/dark mode preference for usability and accessibility. | 1 year |
| sidebar_state | Functional: remembers whether you prefer the dashboard sidebar open or closed. | 1 week |
| localStorage: appearance, accessibility | Functional: stores display preferences such as dark/light mode, font size, and dyslexia font so they persist between visits. | Until cleared |
4. Managing cookies and storage
You can delete cookies and clear browser storage through your browser settings. If you do, you may need to sign in again or reapply appearance and accessibility preferences.
