Cookie notice
Last updated: 6 September 2026
thirds.ai sets two small cookies, and both come from thirds.ai itself.
The cookies we set
| Cookie | What it does | When it ends |
|---|---|---|
__Host-thirds_session | Keeps you signed in. The service needs it to work. | When you sign out, or when the session expires. |
__Host-thirds_visit | Links your first visit to your account if you sign up. It holds a random ID and approved campaign tags only. | 30 days after your last visit. |
During a GitHub or Google sign-in, a short cookie named __Host-thirds_auth_flow protects that one sign-in, and it ends when the sign-in finishes.
What we do not do
We set no third-party cookies and no advertising cookies. We show no consent banner, because there are no cookies that need consent. Our product analytics runs from our own server with a random ID, and the Privacy policy explains what it records.
How to block cookies
Your browser settings let you block or delete cookies for thirds.ai. If you block the session cookie, you cannot stay signed in. If you block the visit cookie, we cannot link your visit to your account, and the rest of the service still works.
