1. Contact Us
For questions about Hibiki (the "App"), or to report a problem, please write to
support@mainichi-apps.win
A reply may take a few days. When reporting a problem, it helps if you can include:
- Your device (for example, iPhone 15 / Android)
- The app version (if the settings screen shows one)
- Which screen you were on, and what you did when it happened
2. How to Use the App
- Pick a length (1 to 60 minutes) and start: a singing bowl rings at the beginning, at the halfway point and at the end.
- If the App goes to the background while the timer runs, the halfway and finishing sounds still play.
- The next time you open the App, the length you used last is already selected.
3. Frequently Asked Questions
- Is what I record sent anywhere?
- No. Records are stored only on your device. There is no account and no sign-in, and nothing is sent to an external server. See the Privacy Policy for details.
- How do I delete everything?
- The App keeps only your 30 most recent completed sessions on the device; older ones are deleted automatically. Deleting the App removes the history and the settings as well. This cannot be undone.
- Can I move my records to a new phone?
- Not at the moment, because the records live only on your device. On a new device you start again from scratch.
- Does it work offline?
- Yes. Everything works on your device, so every feature is available in airplane mode. (the first time a typeface is needed the App downloads the font file from Google's font servers. If either fails, nothing about the App changes. See "Network Communication" in the privacy policy.)
- Are there ads or in-app purchases?
- No.
- How many sessions are kept?
- The 30 most recent. Older ones are deleted automatically. Each entry holds only the date, time and length — nothing else.
- Do the timer sounds play if I leave the App?
- Yes. If the App goes to the background while the timer runs, the halfway and finishing sounds still play.
- How long can the timer be?
- From 1 to 60 minutes.
4. If Something Goes Wrong
- Close the App completely and open it again.
- If that does not help, restart your device.
- Check the App Store / Google Play for an update.
- If it still happens, email support@mainichi-apps.win with the three details listed above.
Reinstalling the App can fix some problems, but it also erases your records. Please treat it as a last resort.
