Google has recently announced that it is introducing new policies for consumer accounts that are either inactive or over their storage limit across Gmail, Drive.
This includes Google Docs, Sheets, Slides, Drawings, Forms and Jamboard files and/or Photos to better align with common practices across the industry, effective from June 1 next year.
After June 1, 2021 if you’re inactive in one or more of these services for two years (24 months), Google may delete the content in the product in which you’re inactive.
