Cookie Policy
Last updated: February 2026
1. What are cookies?
Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work, or work more efficiently, as well as to provide information to the owners of the site.
2. How we use cookies
| Name | Purpose | Duration | Category |
|---|---|---|---|
| sb-*-auth-token | Supabase authentication session | Session | Essential |
| sb-*-auth-token-code-verifier | OAuth PKCE security flow | Session | Essential |
| cookie_consent | Stores your cookie consent decision | 1 year | Essential |
| locale | Remembers your language preference across sessions | 1 year | Functional |
3. Essential cookies
Essential cookies are strictly necessary for the website to function. They enable core features such as user authentication and security. Under UK GDPR and PECR, these cookies do not require your consent.
4. Functional cookies
Functional cookies enhance your experience by remembering choices you make (such as your preferred language). They are not essential to the operation of the site. We only set the locale cookie if you have accepted functional cookies. If you decline, your language preference will still work during your current session but will not be remembered the next time you visit.
5. Your rights under UK GDPR
Under UK GDPR and the Privacy and Electronic Communications Regulations (PECR), you have the right to:
- Be informed about cookies before they are placed on your device
- Withhold or withdraw your consent for non-essential cookies at any time
- Access, rectify, or erase personal data we hold about you
Theme preference (bnn-theme) is stored in browser localStorage only and is not a cookie — it is never transmitted to our servers.
6. Withdraw or change your consent
You can withdraw or change your cookie consent at any time. Clicking the button below will remove your consent record and reload the page, showing the consent banner again so you can make a fresh choice.
