What is deleted
Your profile, everything you synced (tasks, habits, health, money, notes, journal and more), friend connections, messages and shared items you created, and your coupon and subscription records with us. Data on your phone is removed when you delete in the app, or when you uninstall.
What is not deleted
Google Play keeps its own records of purchases under Google's policies. Deleting your account does not cancel a Google Play subscription — cancel it in Google Play → Payments & subscriptions → Subscriptions.
