Osteon uses Google sign-in, so there is no separate password. If you can't get in, check you're using the same email address you signed up with — a different account creates a separate profile with its own progress.
Your progress syncs across devices automatically. To export or delete your data, email us.
Every question has a flag button while you're signed in — use it and the question goes into our review queue with the context attached. That's the fastest way to get a correction made. You can also email us.
Osteon is a study aid, not medical advice. Content may contain errors and AI answers can be confidently wrong — verify anything you intend to act on clinically.
