Quick answers about learning, accounts, downloads, and your study data.
Can I learn without an account?
Yes. Guest learning works without sign-in, and progress is saved on the device. Google sign-in is optional and supports account backup and sync.
What can I study?
Study general Korean, TOPIK packs, practical situations, saved words, and weak words in short sessions.
Is the level check an official TOPIK result?
No. It is a learning estimate that helps you choose a starting point and does not replace an official TOPIK score.
Where should I download the Android app?
Use the official BSKorean download page. It shows the current version and minimum Android requirement.
How do I delete my account?
Signed-in users can permanently delete their account and synced study data from the app settings.
