Cantor uses essential cookies only. No advertising. No tracking. No third-party analytics cookies. Just the minimum needed to keep you signed in and the app working.
Cookies are small text files stored on your device by your browser. They are used to remember information between page loads and sessions. Not all cookies are equal — some are essential for a website to function, others are used for advertising or behavioral tracking. We only use the former.
Set by Supabase when you sign in. Keeps you logged in between page loads. Required for the app to function. Expires when you sign out or after 7 days of inactivity.
Used to refresh your authentication session without requiring you to sign in again. Stored as an httpOnly cookie for security.
Stored in localStorage (not a cookie, technically) to remember that you've accepted this cookie policy, so we don't keep showing you the banner.
We do not use advertising cookies, analytics cookies (e.g., Google Analytics), or social media tracking pixels.
Under GDPR, cookies strictly necessary for the operation of a website do not require explicit consent. All cookies used by Cantor fall into this category. We do not use any cookies that require consent under GDPR.
For users in the EU/EEA, our data processing is based on the legitimate interest of providing a functioning service (Art. 6(1)(f) GDPR) for authentication cookies, and your consent for the cookie consent localStorage item.
You can control cookies through your browser settings. Blocking authentication cookies will prevent you from staying signed in to Cantor. Here's how to manage cookies in common browsers:
