A private email triage tool. It reads several mailboxes read-only, sorts what deserves attention from what does not, and cannot send anything.
This page exists mostly so that the Google OAuth consent screen has somewhere honest to point. If you arrived here from a permissions dialog, the short version is: this is one person's personal tool for reading his own email, it runs on his own laptop, and it is not a product you can sign up for.
Read-only, structurally
The application holds only Gmail read scope. There is no send, reply, draft, delete, or label-modify capability anywhere in the codebase — not disabled, absent. It cannot be talked into sending mail because there is no method to reach.
One user
The only user is its developer, reading his own mailboxes. It is not offered as a service, has no sign-up, and no other person has an account.
Runs on one machine
Everything — the database, the web interface, the sync loop — runs locally on one personal computer. There is no hosted server and nothing is exposed to the internet.
Roles, not mailboxes
Mail is partitioned into separate roles with separate stores and separate rules. Two roles may read one mailbox, split on the delivery address. Retrieval never crosses a role boundary.
Access can be withdrawn at any time from your Google Account permissions page. Revocation is immediate and the application stops being able to read anything.
