Cookie & Storage Policy
1. Summary
RA10 does not use advertising, tracking or analytics cookies. We only use storage in your browser that is strictly necessary to provide the features you ask for, such as keeping you signed in and remembering your settings. Under the Privacy and Electronic Communications Regulations (PECR), strictly necessary storage doesn't need consent, which is why we don't show a cookie banner.
If we ever add non-essential cookies (for example analytics), we'll update this page and ask for your consent first.
2. What we store
RA10 mostly uses your browser's local storage rather than cookies. It stays on your device and isn't sent to our servers with every request.
| Name | Purpose | How long |
|---|---|---|
ra10.auth.token | Keeps you signed in securely (Supabase session) | Until you sign out |
ra10-theme | Remembers light or dark mode | Until cleared |
ra10_a11y_prefs_v1 | Remembers your accessibility settings (text size, contrast, motion, font, spacing) | Until cleared |
ra10_legal_accepted_* | Temporary record of terms acceptance if our database can't be reached | Until cleared |
ra10_onboarding_* | Remembers where you are in account setup | Until setup is finished |
Credit and activity keys (e.g. ra10_credit_*) | Shows your recent credit activity quickly | Until cleared |
| Guest ID | Counts free guest uses before you sign up | Until cleared |
| Dismissed-message and layout keys | Stops popups, banners and tips reappearing once closed; remembers your mobile dock order | Until cleared or for the session |
Service worker cache (ra10-v2) | Lets pages load faster and work offline | Until a new version replaces it |
3. Third-party services
- Stripe and GoCardless set their own cookies on their checkout pages to process payments securely and prevent fraud. These only apply if you start a payment.
- Google Fonts, jsDelivr, cdnjs, unpkg and Unsplash deliver fonts, scripts and images. They don't set cookies on RA10, but your browser shares your IP address with them to download files.
- Embedded tools such as diagrams.net, used in some revision activities, may set their own cookies when you use them.
4. Controlling storage
You can clear RA10's storage at any time in your browser's settings (usually under Privacy → Site data). Clearing it will sign you out and reset your settings. Blocking it completely will stop sign-in from working.
