1. What cookies are
Cookies are small text files stored on your device when you visit a website. Similar technologies include local storage and session storage. They help sites remember your session and preferences.
2. How we use cookies
CoStartups (costartups.app) uses cookies and similar storage primarily to keep you signed in and to protect your account. We do not use third-party advertising cookies.
3. Cookies we use
| Name / type | Purpose | Duration |
|---|---|---|
| Supabase auth cookies (sb-*) | Maintain your login session and refresh tokens securely | Session to persistent (see auth settings) |
| Strictly necessary storage | Temporary client state required for the application to function | Session |
Cookie names may vary by environment. Auth cookies are set by Supabase when you sign in.
4. Third-party cookies
Our authentication and database provider (Supabase) and hosting provider (Vercel) may set cookies or process technical identifiers as part of delivering the service. We do not embed social advertising pixels on CoStartups at this time.
If you follow links to external sites (for example a company website on a profile), those sites may set their own cookies under their policies.
5. Legal basis
Strictly necessary cookies are used based on legitimate interests and/or contractual necessity so you can log in and use the service. Optional analytics or marketing cookies, if introduced in future, will be used only with consent where required by UK law.
6. Managing cookies
You can control cookies in several ways:
- Browser settings: block or delete cookies in your browser preferences. Blocking all cookies will prevent you from staying signed in
- Sign out: clears the active session on your device
- Private browsing: cookies are cleared when you close the window
For instructions, see your browser help pages (Chrome, Safari, Firefox, Edge).
7. Local development
If you run CoStartups locally, auth cookies may be scoped to localhost. Our cookie janitor clears conflicting Supabase cookies when multiple projects share the same browser on localhost.
8. Updates and contact
We may update this policy when our use of cookies changes. See the date at the top of this page.
