Yes, So We Made the Login Tab to Avoid Communication Problems When People Reach Us By Email, We Check If They Are Our Users, If Not, We Ignore The User When Users Contact Us, They Have To Give That E-mail In Their E-mail Or In Their E-Mail They Have Problems!
Someones picture, name and email is not simple data. The fact that you state that is reason enough to not use the app. Nobody knows what you are doing with that “simple” data. And if it was for entertainment you could just stop collecting that.

WE MAKE APPLICATIONS FOR EVERYONE
