What happens when your Google Account is inactive
When your Google Account has not been used within a 2-year period, your Google Account, that is then deemed inactive, and all of its content and data may be deleted. Before this happens, Google will give you an opportunity to take an action in your account by:
Sending email notifications to your Google Account
Sending notifications to your recovery email, if any exists
Google products reserve the right to delete your data when your account has not been used within that product for a 2-year period.
December 1, 2023 is the earliest a Google Account will be deleted due to this policy.
