Cookies and browser storage
Last updated 13 October 2026
The short version
We set one cookie, to keep you signed in, and keep one setting in your browser’s local storage, your colour theme. We use no analytics, advertising or tracking cookies.
[TO CONFIRM: solicitor that both items count as strictly necessary, so that no consent banner is needed]
What we set
| Name | Type | Purpose | Lasts | Essential |
|---|---|---|---|---|
| better-auth.session_token | Cookie, first party | Keeps you signed in. Set when you sign in or sign up. | Up to 7 days, or until you sign out | Yes |
| whatcut-theme | Local storage, first party | Remembers the colour theme you chose. Never sent to us. | Until you clear your browser data | Yes |
On a secure connection the cookie name starts with __Secure-.
Other companies
When you go to Stripe to pay, or to Google to sign in, those companies run their own pages and may set their own cookies. We do not control them, so see their own policies. Our pages load no third-party scripts, images or trackers, and our fonts are served from our own site.
Controlling them
- You can delete cookies and site data in your browser settings. You will be signed out and your theme will reset.
- If you block the sign-in cookie, you cannot sign in.
