If I don't want to use voice calls or SMS messaging, these permissions are excessive.

I also can't distinguish between giving Ring permission to access all my contacts' details and send them to some third party, and giving Ring permission to associate ring IDs with contacts without exposing other details about that contact to Ring.

Also, you don't need storage permission to store app-specific data, only to access the "external" storage. (In general, this is the storage you see when you mount the phone over USB.) Presumably, this permission is to support copying an existing key from a PC.

Note that these problems are not Ring's fault, but caused by Android's permissions system. Fixing it in Ring would require splitting the app up into pieces for voice, sms, text, etc. Possible, but a lot of effort.
