Restore or manage Massy Plus
Open Settings inside Massy and choose Restore purchases with the Apple Account that subscribed. Choose Manage subscription to change plan or cancel through Apple.
Clear saved measurements
Delete an individual check-in from the full timeline, or use Settings → Delete all local data to remove every check-in, goal, reminder, and milestone. This does not cancel a subscription. Massy has no account or cloud profile for us to delete.
