Adios needs the ability to change the label on emails (in order to move them into the inbox at your chosen times). This permission is unfortunately also the permission needed to access emails. If you know anyone at Google who can change this, please let us know ;) as we're keen to ask for as little permission as possible.

Importantly though, the content of emails never ever hits our system. The API calls we use only retrieve msg ids and uses those to change the labels. These are never stored.

But in the future you could store them and users wouldn't know something changed, correct?
