Cookies and browser storage
The Opener and Callers applications
We use only strictly necessary cookies for sign-in and security. The application does not work without them, so we do not need consent for them (Czech Act No. 127/2005 Coll., on Electronic Communications, Section 89(3), and Directive 2002/58/EC Art. 5(3)). We do not use advertising or analytics cookies and we do not measure traffic in the application.

All of them are available only to our domain, only over HTTPS, and are not readable by scripts.
In browser storage (localStorage), the application remembers your appearance settings (theme, colour, density, font size), screen layout, the last selected view, dismissed notices and unfinished drafts of texts, so that you do not lose them. Drafts are deleted after 30 days and on sign-out.
The Opener Team browser extension
The extension stores in the browser an access token, the language, appearance, the position of its badge, a pause flag and confirmation that you have read how the extension handles data. For the duration of the browser session, it remembers pairs of URLs belonging to the same profile. It does not read LinkedIn cookies or send them to our server.
