gmail-search
A personal tool for searching one's own Gmail mailboxes.
gmail-search is a small program that runs only on its owner's own computer. It lets the owner search and read their own Gmail accounts from one place, with read-only access. It is not a public service and is not offered to other users.
It cannot send, delete or change email. Access tokens stay on the owner's computer, and no server run by the developer receives any email data.
