Some content and features, including certain AI-assisted experiences, Pro and Premium plans, hearts, subscriptions, and lifetime access, require separate in-app purchases or subscriptions. Important notes for learners: • Learning stats and progress are currently saved locally on your phone. Uninstalling the app may reset your learning stats, and switching to another phone during your study journey is not recommended at this stage. • Social sign-in with Apple and Google is available, but we still plan to improve and polish this experience further in future updates. We plan to continue expanding SQL Hero with more languages, more chapters, and more additional-question content in future releases.
