The advertising and analytics integrations (Meta Ads, Google Analytics, Umami) connect to the operator’s own accounts and are not reachable from a customer workspace, so no customer content passes through them.
We will update this page before a new subprocessor begins handling customer content. If you need advance notice of changes, write to [[email protected] — mailbox must exist and be monitored].
