No, we require only some of the permissions, but unfortunately Twitter does not have a more granular permission model that allows us to only choose the permissions we need. Hence you see this big list of permissions with many that we don't use or need
We do need the permission to follow other accounts, but only if you excplicitly click a "follow button", for example if you find an interesting accounts from a specific location, or with unique interests or simply just followed you recently
We also need the permission to tweet because our scheduler (which has many advanced functions not found in other services) needs that permission to function, obviously!
We never update your profile info, block, mute or delete tweets at any point in time.
We also explain each listed permission in details here
