Google One is a simple plan for expanded storage that includes extra benefits to help you get more out of Google.

You can use the Google One app to:
• Manage your storage plan, which covers Google Drive, Gmail and original quality photos and videos in Google Photos.
• Contact our team of experts with just one tap. If you need help with Google products and services, our team is here for you.
• Access member benefits like Google Play credit and special hotel pricing.
• Share your plan with up to 5 family members, giving everyone more storage plus access to extra benefits.

Initially, Google One will only be available on a limited basis. If you have a paid Drive storage plan, you’ll be automatically upgraded to Google One over the coming months.

We're working on making Google One more widely available.
