Hubort's full privacy policy is at https://hubort.app/privacy.

In short: this add-on reads your own conversations from the AI services you switch on, with the sessions you're already signed in to, and sends them only to the Hubort desktop app on your own computer (127.0.0.1). They are never sent to us; Hubort has no server to send them to. The add-on keeps its settings and sync bookkeeping (each chat's id, title and last-changed time) in the browser's extension storage, and never message text. It only reads: it never changes anything in your accounts.

Its "Report a problem" link opens a page on hubort.app with this browser's diagnostics (versions and error codes, never a conversation or an account's name) after the "#" in the address, which the browser doesn't send; nothing is sent unless you press Send on that page. When the add-on is uninstalled, the browser opens hubort.app/uninstalled, which asks one optional question.
