Terms of Service

Effective September 2, 2026

By installing or using Drive Folder Size, you agree to these terms. If you do not agree, do not install or use the extension.

Purpose

Drive Folder Size is a free productivity tool that calculates and displays recursive folder sizes in the Google Drive web interface. It is an independent extension and is not affiliated with, endorsed by or sponsored by Google.

Acceptable use

You may use the extension only with Google accounts and Drive items you are authorized to access. You must not use it to violate applicable law, another person’s rights, or Google’s terms and policies.

Google Drive access

The extension requires user-authorized, read-only Google Drive metadata access to provide folder totals. It does not request file contents and cannot upload, modify, move or delete Drive files. Details are provided in the Privacy Policy.

Availability and accuracy

The extension is provided on an “as is” and “as available” basis. Folder totals depend on the metadata returned by Google Drive and on items accessible to the connected account. Service interruptions, API limits or changes to Google Drive may delay calculations or affect availability.

Changes and termination

The extension or these terms may be updated to improve functionality, security or policy compliance. You may stop using the service at any time by revoking its Google Account access or uninstalling the extension.
