experience with Realitymine / Realitymeter?

I usually do surveys from Ipsos for some points and the other day I got notified that I can get some points for using Realitymine/Realitymeter. From what I can tell it's an app/VPN that just wants to be in the background to see my online behavior (to sell my purchase journies to marketing companies basically)

Has anyone had experience with them? I don't care much about privacy but I definitely don't want to be scammed or hacked.
