How Unico uses Google data

To show, search, archive, label, draft, and send your mail, Unico asks Google for permission to read and change your Gmail messages, labels, and drafts. That permission is https://www.googleapis.com/auth/gmail.modify, and it is the only Google permission Unico asks for.

Your mail is downloaded from Google straight to your computer and kept in an encrypted database. Unico's servers never receive it. Attachments you open and your system's notifications and backups can keep copies outside that database.

Limited Use

Unico's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements. The use of information received from Google Workspace scopes will adhere to the Google Workspace API User Data and Developer Policy, including the Limited Use requirements. Unico does not use Google user data, or data derived from it, to develop, improve or train generalized or non-personalized AI or machine-learning models, and does not transfer it to anyone for that purpose.
