I am not familiar with T11 mobile app. As I understand, if you train players with mobile app, the skill points may be auto assigned. If you use T11 mobile app but do not train player with it, auto assign is unlikely. Anyway, to be safe, remember log out the app before leaving and uninstalling.

I removed the T11 apps before logging out. Now, even if I only play with computer, occasionally sp are automatically assigned.
