Cookie Policy
Effective date: 2026-07-16
EdxAI uses a small number of strictly-necessary cookies (and equivalent browser storage) to make the Service work. We do not use advertising, marketing, or cross-site tracking cookies, and we do not sell or share the information they contain.
| Cookie / storage | Purpose | Duration |
|---|---|---|
| Authentication session (Supabase) | Keeps you signed in | Session / until logout |
| CSRF token | Protects the account-connect flow | Short-lived |
| Referral attribution (edxai_ref) | Credits a referral to the person who shared a link | Short-lived |
The EdxAI extension also stores your last result, sign-in session, model choice, and overlay position on your own device, so it can restore them — this is strictly-necessary functional storage, not tracking.
Because we use only strictly-necessary cookies, most jurisdictions do not require a consent banner for them. If we ever add analytics or any non-essential cookie, we will update this Policy and, where required, request your consent first. See our Privacy Policy.
