No — your guest progress is automatically merged into your new account when you sign up.
Yes, with an account — sign in with the same account on each device and Cloud Sync keeps your progress consistent across them. Guest Mode progress is local to one device only.
No — course progression depends on completing lessons on the learning path; quests and the daily goal reward XP but don't gate or skip course content.
No — Guest Mode has no server-side backup, so progress made only as a guest is not recoverable after uninstalling or clearing local storage.
