CertPost uses cookies and similar local storage only to run the service. We do not use advertising cookies, and we do not sell your browsing data.

What we use

Authentication cookies. When you sign in, we store a secure session so you stay logged in and so we can protect your account. Without these, the app cannot keep you signed in.
Preference storage.We remember choices such as your light or dark theme, and we briefly use your browser’s local storage to carry a domain from the homepage check into signup. These stay on your device.
Security. Cookies that help us detect and prevent fraudulent or abusive use of the service.

What we do not use

We do not run third-party advertising or cross-site tracking cookies. If we ever add optional analytics, we will ask for your consent first and update this page.

Managing cookies

You can clear or block cookies in your browser settings. Blocking the authentication cookies will stop you from signing in, because the app relies on them to keep your session. Preference and security cookies can be cleared at any time without losing your account.
