Shortener.dev reads the address of a tab only when you open the extension on it or right click a link, to fill in the link you want to shorten. It does not read page content, run on websites in the background or track your browsing. Nothing is sent until you click "Shorten link".

• Web address of the current tab: only for the tab you open the extension on, or the link or page you right click and choose “Shorten”. The address is shown in the extension and sent to our API only when you choose to shorten it. The extension does not read page content, does not track your browsing history and does not run on the pages you visit.
• Sign in token: after you sign in, a token for your account is kept in the browser’s extension storage so you stay signed in. Signing out removes it.
• Preferences: your light or dark theme, and the last link picked from the right click menu, are kept in the browser’s extension storage on your device.
• Your links and analytics: the extension loads your short links, domains and click analytics from our API to show them to you.

When the extension is installed or removed, it opens a page on shortener.dev with the browser name and extension version so we can show setup help and collect optional feedback. The extension contains no ads, analytics or third party tracking code.
