## Privacy policy — Mail Pixels The extension shows which emails in the Gmail, Yandex Mail and Mail.ru web apps contain an open-tracking pixel and names the tracker. It has no server, no account, no analytics and no ads. **What the extension sees on a page:** only on mail.google.com, mail.yandex.ru (.com, .by, .kz, .uz), e.mail.ru, its script looks at the addresses of images and CSS backgrounds inside recognised open-message containers and compares them with a built-in tracker list. It does not read or store subjects, senders, recipients or message text. The address of a found pixel stays only in the page itself (so it can be put back if you switch the extension off) and is gone when the page is closed. **What is stored, only on your device:** one value — whether the extension is on. **What is sent outside your browser:** nothing. The extension makes no network requests and downloads no lists or code. **What the extension cannot do:** it works inside an email that is already open. In Yandex Mail it swaps the address of a found pixel before it is requested; in Gmail and Mail.ru the pixel may load first. It does not see unknown trackers, and the mail service itself knows the email was opened. To be sure you don't report opens, turn off automatic image loading in your mail settings. **What is never collected:** personal data, browsing history, email content, analytics, advertising identifiers. Nothing is sold or shared with the extension's author or anyone else.
