This policy covers the personal automation tools published by German Velibekov that connect to Google services through OAuth, including gws-cli and n8n DNA Invoice (the “Apps”).
Who uses the Apps#
The Apps are personal tools operated by their owner for their own Google account. They are not offered as a public service.
What Google user data the Apps access#
When you authorize an App, it may access the Google Workspace data covered by the scopes you approve on the Google consent screen, such as Gmail messages, Google Drive files, Calendar events, Docs, Sheets and Tasks.
How the data is used#
Google user data is used only to perform the actions the account owner requests, such as reading, searching, creating or updating their own emails, files and events. The data is not used for advertising, is not sold, and is not used to train AI or machine-learning models.
Storage and security#
OAuth tokens are stored encrypted on the owner’s own devices or self-hosted automation server. Data retrieved from Google APIs is processed locally and is not stored on any third-party server operated by the Apps.
Sharing#
Google user data is not shared with third parties, except as required by law.
Limited Use#
The Apps’ use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Revoking access and deleting data#
You can revoke the Apps’ access at any time from your Google Account permissions page. Revoking access invalidates the stored tokens. To request deletion of any locally stored data, contact the address below.
