Q. I don't feel any vibration.
A. Please use a real device that supports Core Haptics (iPhone 12 or later). It won't work in the Simulator or on unsupported devices.
Q. Where is my data stored?
A. By default, records are stored only on your device. Only if you agree to "Send Usage Data" in Settings — available only on devices set to Japan — some usage data is sent to the developer together with a random ID. See the
Privacy Policy for details.
Q. How do I stop sending usage data, or delete data I've already sent?
A. You can stop at any time in Settings > Send Usage Data. To delete records already sent, see "Deleting Your Data" in the
Privacy Policy and contact us below.
Q. How do I delete my records?
A. You can delete all records at any time from the log screen inside the app.
