How can we help?
Answers to the most common questions about Gomu. Can't find what you need? Email us — we read every message.
How do I delete my account?
Open the app, go to Profile → Danger zone, and tap Delete account. Confirm twice and everything — your saved words, progress, streaks, achievements, and your login — is permanently removed. This can't be undone.
Why did my streak reset?
Streaks count consecutive calendar days with at least one clip watched or review completed. If a day passes with no activity, the streak resets the next time you open the app.
A video won't play — what do I do?
Some clips stream directly from YouTube; a poor connection or a video the uploader removed can cause a playback error. Try another clip, then check your connection. If it keeps happening on multiple clips, email us with your device model and iOS version.
How does spaced repetition review work?
Every word you save gets scheduled for review based on how well you remember it — words you know well come back less often, words you struggle with come back sooner. Open the review deck from the Vocab tab whenever words are due.
Where do the video clips come from?
Clips are sourced from YouTube — dramas, news, and creators teaching Japanese. Every clip credits its original channel in the app, with a direct link to watch it on YouTube.
Does Gomu show ads or sell my data?
No. Gomu has no ad network and no analytics or tracking SDKs. See our Privacy Policy for the full details on what we collect and why.
