Cookie Policy
Last updated: 6 September 2026
1. What are cookies?
Cookies are small text files stored on your device when you visit a website. They are used to remember information about your visit and to enable certain functionality. This Platform uses only the minimum cookies necessary to operate securely.
2. Cookies we use
| Cookie name | Type | Purpose | Expiry |
|---|---|---|---|
| sb-access-token | Strictly necessary | Supabase Auth — authenticates your session with the API. | 1 hour (auto-refreshed) |
| sb-refresh-token | Strictly necessary | Supabase Auth — refreshes your session without re-login. | 60 days |
| __vercel_live_token | Strictly necessary | Vercel infrastructure — routes requests to the correct deployment. | Session |
We do not use advertising cookies, analytics tracking cookies (e.g. Google Analytics), social media cookies, or any third-party tracking pixels.
3. Local storage
In addition to cookies, the Platform may use browser localStorage for lightweight UI preferences (e.g. a remembered tab or filter state). This data never leaves your browser and is not transmitted to our servers.
4. Can I disable cookies?
The cookies listed above are strictly necessary for the Platform to function — without them you cannot log in or maintain a session. You may disable cookies via your browser settings, but doing so will prevent you from using authenticated features of the Platform.
Since we use no non-essential cookies, there is no cookie consent banner on this Platform. If that changes, we will update this policy and add a consent mechanism.
5. Third-party services
- Supabase (supabase.co) — sets authentication cookies. Supabase processes data under its own Privacy Policy.
- Vercel (vercel.com) — our hosting provider. May set infrastructure cookies. See Vercel Privacy Policy.
6. Changes to this policy
We will update this policy if our cookie usage changes. The “Last updated” date at the top reflects the most recent revision. Continued use of the Platform after an update constitutes acceptance of the revised policy.
