Privacy policy: humidon-mailcopy
Last updated 15 November 2026
Who uses it
humidon-mailcopy is a private tool used by a single person to access their own Google account. It isn't offered to anyone else.
What data it accesses
With the owner's consent, it uses the Gmail API with the read-only scope https://www.googleapis.com/auth/gmail.readonly to read e-mail messages, their headers and labels. It does not request permission to send, delete, modify or label mail, or to access any other Google service.
How the data is used
Messages are copied to a server in the owner's home and processed there by a locally running AI model, to produce daily summaries and suggested reply drafts for the owner. Drafts are only shown to the owner; the tool never sends mail.
Storage and sharing
Data is stored only on the owner's home server, which isn't reachable from the internet. It isn't sold, shared with or transferred to any third party, and it isn't used for advertising or to train AI models.
Google API Services User Data Policy
humidon-mailcopy's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Revoking access and deletion
Access can be revoked at any time at myaccount.google.com/permissions. Revoking stops all further access. The owner can delete the local copy at any time.
