The session cookie
When you sign in, we set a secure session cookie that keeps you signed in as you move through the studio. It holds a random session id and nothing else, and it is removed when you sign out or when it expires.
The theme cookie
The studio remembers whether you chose the light or the dark look in a preference cookie. It holds that one word and nothing about you.
What we do not set
No analytics, no advertising and no third-party cookies. Stripe sets its own cookies on its checkout and billing pages; those pages are Stripe's and covered by Stripe's policy.
Removing them
Signing out removes the session cookie. Both cookies can also be cleared in your browser's settings; you are then signed out and the theme goes back to the default. Questions: support@greppi.ai. See also our privacy policy.
