A private, single-user automation tool.
Herm is a personal automation tool operated by one individual for their own use. It is not a public service, has no other users, and is not distributed or offered for sale.
The tool performs routine personal tasks on behalf of its owner. When its owner grants it access to a Google account, it uses that access to read the owner's own email so it can surface things that need attention — appointment reminders, shipping notices, bills, and similar correspondence. It does not send mail, modify or delete messages, or access any account other than the one its owner explicitly authorizes.
Only the owner's own data. There are no other users, no sign-up, and no accounts are created for anyone else.
How data is handled is described in the Privacy Policy, and use of the tool is governed by the Terms of Service.
