Common questions
How do I delete my account?
Use Settings → Account → Delete account in the app, or follow the account-deletion page. After identity verification, we aim to delete or de-identify account data within 30 days, except for limited records that must be retained for legal, security, fraud-prevention, or billing reasons.
Do I need an account to study?
No. Guest learning records are stored on your device, except when a feature needs to download content or audio. An account is only needed if you want to sync progress across devices.
My audio isn't playing.
Check that your device is not in silent mode and that the in-app volume is turned up. Some audio may require an internet connection, particularly on first playback. If the problem persists, email us with your device model, operating system, and OS version.
I found a mistake in the content.
Japanese varies by context, region, generation, and speaker, and some explanations are intentionally simplified. If you believe an item is misleading, unclear, or unsuitable for its stated context, send us a screenshot and the reason so we can review it.
Does Moshibary follow textbook Japanese?
Moshibary prioritizes Japanese that people commonly use in everyday situations. It may differ from prescriptive textbooks or exam rubrics. For exam-standard answers, academic grammar, professional translation, or important formal writing, use authoritative materials or qualified instruction alongside the app.
