Quick answers

Frequently asked questions

1What exactly counts towards my free 15GB storage limit?⌄

Your 15GB free storage is shared across Google Drive (for files, documents, spreadsheets, presentations), Gmail (for emails and attachments), and Google Photos (for photos and videos uploaded in 'Original quality' after June 1, 2021, or any quality before that date). Items in Google Docs, Sheets, Slides, Drawings, Forms, and Jamboard files created before June 1, 2021, do not count towards this limit.

2What happens if I exceed my 15GB free storage limit?⌄

If you exceed your 15GB limit, you will no longer be able to upload new files to Google Drive, back up photos to Google Photos, or receive new emails in Gmail. You will need to either free up space by deleting existing content or upgrade to a paid Google One plan to continue using these services normally.

3Can I share my free 15GB storage with family members?⌄

No, the free 15GB storage is tied to your individual Google Account and cannot be shared with other family members. Storage sharing is a feature exclusive to paid Google One plans, where the purchased storage can be shared among up to five additional family members.

4Is my data stored in Google One's free tier secure?⌄

Yes, Google employs industry-leading security measures, including encryption in transit and at rest, robust authentication protocols, and continuous threat detection, to protect all data stored across its services, including the free 15GB provided by Google One. Your data privacy is also governed by Google's comprehensive privacy policy.

5Are there any hidden costs or automatic upgrades after using the free 15GB?⌄

No, there are no hidden costs or automatic upgrades. The 15GB is genuinely free. If you exceed the limit, your services will simply stop accepting new data until you either delete existing content or manually choose to subscribe to a paid Google One plan. You will not be charged without explicit consent.
