What? in the world is this

I’ve fiddled with this one and off all morning. It keeps wanting me to reset my password, then I did, now when it launches it asks me to download a Pinterest app (which is what I thought this was) and then when I say yes it errors trying to open all sorts of ‘deeplink’ things that look ominous. I am trying to uninstall in now. I thought it would quickly take me to my pinterest boards but it is NOT WORTH IT and may in fact be damaging.
