Q: Can I study without creating an account? — Yes. All study content works without signing up. An account only syncs progress between devices.
Q: If I lose my phone, is my progress gone? — Not if you were signed in. Progress syncs to the server and comes back when you sign in on a new device. If you never made an account, it only existed on the old device.
Q: How do I delete my account? — Settings → Account → Delete account, inside the app. See the Delete account page for details.
Q: I found wrong content, where do I report it? — Email [email protected] with the word or sentence and a screenshot if you have one. Dictionary content is CC BY-SA, so corrections can be contributed back upstream.
Q: I bought a plan and want a refund — Refunds are handled by the app store you bought from, not by me. If you get stuck, write to [email protected] and I will help you match the order.
