Optional advertising measurement is off until you accept it. It sends browsing events and identifiers to a trusted external advertising measurement provider. In the app, it is limited to signup and completion conversions on onboarding pages. Advertising personalization is disabled. Rejecting does not prevent use of the service.
Use Privacy / Do not sell or share on the website or during onboarding, or Settings > Legal Information in the app, to change your choice or withdraw consent. Global Privacy Control keeps optional advertising off. Your choice is stored for up to 180 days in this browser, separately on each site origin. Withdrawal stops future optional tracking; it does not undo information already sent. Advertising disclosures may qualify as sharing under applicable privacy laws.
