One cookie, and it only keeps you signed in.

What is set
| Name | Purpose | Lifetime |
|---|---|---|
sb-*-auth-token | Your session, so you stay signed in between pages. Set only after you sign in. | Until you sign out, or a year |
That is the whole list. There are no advertising cookies, no third-party analytics, and no tracking pixels in our emails.
Browser storage that is not a cookie
Some conveniences are kept in your browser's local storage and never sent to us: your appearance and generation preferences, tutorial progress when you are signed out, and the preview runs you make without an account. Clearing site data removes them.
Third parties
When you buy credits you are taken to Stripe's checkout page, which sets its own cookies under Stripe's privacy policy. Embedded tutorial videos load from YouTube's privacy-enhanced domain, which sets no cookies until you press play.
Your choice
Because the only cookie is the session cookie, there is no consent banner: blocking it means you cannot stay signed in, and everything else on the site works without it.
