Privacy Policy
brain-ingest · Last updated: November 10, 2026
This policy explains how brain-ingest ("the app") handles information. The app is operated by [YOUR NAME OR COMPANY] ("we", "the developer") and is a personal tool run on the developer's own computer.
Information the app accesses
When the owner signs in with Google and grants permission, the app accesses Gmail data in that account: the content, headers (sender, recipients, date, subject), labels, and attachment filenames of email threads the owner has labeled brain/ingest. The app requests only the Gmail scope https://www.googleapis.com/auth/gmail.modify, which it uses to read those threads and to move them from the brain/ingest label to the brain/done label. It does not access Google Drive, Contacts, Calendar or any other Google service, and it does not read unlabeled email.
How information is used
Labeled threads are converted to Markdown text files and stored in a folder on the owner's computer, where they are used only to build the owner's private notes. The data is not used for advertising, profiling, or to train machine-learning models by the app itself.
Storage and security
Saved notes and the OAuth access and refresh tokens are stored only on the owner's computer, in files readable only by the owner's user account. The app has no server and does not upload email content or tokens to any service operated by the developer. The owner can revoke the app's access at any time (see below).
Sharing and disclosure
We do not sell, rent, or share Google user data with anyone. The data is transferred only between Google's servers and the owner's own computer. Notes may later be read by software tools the owner chooses to run on their own computer; this is under the owner's control and is not a disclosure by the app.
Google API Services User Data Policy
The app's use and transfer to any other app of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Specifically, the app uses Google user data only to provide and improve the user-facing feature described above; does not transfer it to others except as needed to provide that feature, to comply with law, or as part of a merger or sale; does not use it for serving advertisements; and does not allow humans to read it except with the owner's consent, for security, or to comply with law.
Retention and deletion
The app keeps data until the owner deletes it. The owner can delete saved notes by deleting the files in the notes folder, and can delete stored tokens by deleting the app's configuration folder on their computer.
Revoking access
Access can be revoked at any time at myaccount.google.com/permissions by selecting brain-ingest and choosing "Remove access".
Children
The app is not directed to children under 13 and does not knowingly collect their information.
Changes
We may update this policy; the "Last updated" date above will change when we do.
