Cookie Policy
Effective date: August 24, 2026
This Cookie Policy explains the cookies Quathos Sign uses. Unlike a purely static site, Quathos Sign is an application and needs a small set of cookies to work.
1. What are cookies
Cookies are small text files stored by your browser. Quathos Sign uses only first-party cookies. We do not use advertising or cross-site tracking cookies.
2. Strictly necessary cookies
These are required for the Service to function and cannot be turned off:
- Session cookie (qsign_session): keeps you signed in after authentication.
- CSRF token: protects forms and state-changing requests against cross-site request forgery.
3. Preference cookies
These remember your choices to improve your experience:
- locale: remembers whether you chose English or Portuguese.
- theme: remembers whether you chose the light or dark theme.
4. No advertising or analytics tracking
We do not use cookies to build advertising profiles or to track you across other websites. Because the cookies we set are strictly necessary or preference cookies, no third-party ad network receives them.
5. Managing cookies
You can delete or block cookies in your browser settings. If you block strictly necessary cookies, you will not be able to sign in or use the Service. If you clear preference cookies, your language and theme reset to the defaults (English, following your system theme).
6. Changes and contact
If our use of cookies changes, we will update this page and its effective date. Questions? Email contact@quathos.com.
