Cookie & Storage Notice
Last updated: 2026-05-02
Sigrel uses the minimum cookies and browser storage entries required to keep you signed in and protect the product against bots. We do not use analytics cookies, ad targeting, or third-party trackers. No consent banner is shown because no non-essential cookies are placed.
Essential — set on every page
| Name | Set by | Purpose | Duration |
|---|---|---|---|
sb-*-auth-token | Supabase | Keeps you signed in. Contains your session JWT and refresh token. | Until you sign out, or 1 hour for the access token (refreshed silently) |
cf_clearance, __cf_bm | Cloudflare | Set by the Turnstile bot-protection challenge on the auth pages. Verifies the browser is not an automated script. | 30 minutes to 30 days, depending on the challenge |
Local storage entries
In addition to cookies, the web app uses your browser's localStorage and sessionStorage for:
- Caching the Supabase session client-side (matches the cookie).
- Remembering UI preferences (e.g. whether the dashboard sidebar is collapsed).
Service Worker (PWA)
If you install Sigrel as a Progressive Web App, the service worker caches the offline shell, app icons, and the manifest. No personal data is cached. The cache is cleared when you uninstall the app or clear site data from your browser.
What we don't set
- Google Analytics, Meta Pixel, or any other analytics provider.
- Advertising or remarketing cookies.
- Cross-site tracking pixels.
Clearing cookies
You can clear all Sigrel cookies and storage from your browser's site settings. Doing so will sign you out. If you want to delete your account entirely, use Settings → Privacy → Delete account.
