The extension can store your login credentials if you don’t want to logout for faster access. The extension doesn't track your browsing history, and it doesn't send any content from any page you visit to our servers, with one exception: The article you intend to save to your profile sends to our server (using an encrypted HTTPS connection). We log requests to our servers in order to monitor and improve service, but those logs aren't connected to your identity. Furthermore, the extension won't send or use any kind of browser fingerprinting technology to identify your computer.
