hello!, I just did it!, I uninstalled it!.
I don't know what did it, but here's the list of things I checked:
-I disabled it from within the app
-I re-enabled the default screen lock thing
-in security, I disabled it under "applications with use access" (aplicaciones con acceso de uso. sorry I don't know the proper english names for these things).
-still in security then I checked "automatic start manager" (gestión de inicio automático), I don't remember if it was there, but if it's there, disable it.
-still in security then I checked on "device manager" (administradores de dispositivos). I disabled it.
-then I went to applications, and on the list of running applications I stopped it and stopped all its processes.
-then still under applications I deleted data and cache and finally I uninstalled it.
sorry for the bad english. I hope this helps.
