Search & Sidebar for Claude does not run any servers and does not collect, store or sell
any personal data.
Search: when you search with the Claude search engine this add-on adds, Firefox sends
your search to claude.ai, the same way it sends searches to any other search engine.
Selected text: when you select text on a web page and pick an item in the add-on's
Claude menu, that text is sent to claude.ai so that Claude can answer. This happens only
on your click, only after you have allowed it in the Firefox permission prompt, and you
can withdraw that permission at any time in the add-on settings or in the Firefox Add-
ons Manager.
The add-on stores two settings in your browser (whether the menu is shown and where answers open), a count of how many times you have used the Claude menu (so it can ask you once for a review), and, if the usage meter is on, your latest usage reading. None of this leaves your browser.
