As of now, it's completely passive. It's just a wrapper around their website with some features which reduce friction.

For example, we have a DND (Do Not Disturb) system which is opt-in. Most people don't know about this. Originally signing up required a new user to send a series of text messages to register (opt-in) and select what kind of ads (spam) they would tolerate. For example you could say block everything except bank offers.

This app walks you through the process.

I keep a close watch on permissions etc which apps ask for. This app doesn't really want access to anything unusual.

This on IOS, I know nothing about Android.
