The OurLogins add-on collects no data. When you ask it to fill, it reads the current page's address and sign-in boxes and asks the OurLogins app on your computer for the logins saved for that website. The username and password you choose pass from the app to the page and nowhere else. The add-on never connects to the internet, stores no passwords or browsing history, and has no analytics or tracking.
