Answer 1

What is your doubt actually?
Edit :
everything saved content on SoloLearn will be saved at SoloLearn servers. not in our mobiles. Even you can use account in both mobiles. Just need login to use your account

Answer 2

Nothing, just login with the same email, login, and password. Don't worry.
As I can understand you afraid of losing your level, xp and account. Am I right?
