It's been a while since I've been using this app to take inventory of my hotwheels and it's been great, it's a very good idea Diecarz. But I found out today when I opened it that my account has been replaced by another Gmail, profile picture and name; And the worst thing is that this hacker put his face in the profile picture and even had an account on the app.

I need help from the devs with this issue please, I don't want to leave this app because of a silly hacker. The photo shows the hacker and his Gmail will be sent to the private one.
