Analytics cookies

We do not set analytics or marketing cookies on the public website. Inside the authenticated app, we collect aggregated usage telemetry server-side (no client cookie required) to understand which features are used. See Privacy Policy § 2.5.

Third-party services

When you connect your X account, the X domain may set its own cookies in your browser as part of the OAuth flow. These are governed by X's privacy policy. Similarly, Stripe (during checkout) and Resend (when you click email links) operate under their own cookie policies.

How to opt out

  • Disable cookies from your browser settings — note that sign-in will break.
  • Clear cookies any time from your browser.
  • Sign out from FantoClient to invalidate the session cookie immediately.
