Privacy Policy

The short version: HearTime has no account, no ads, and no analytics. Everything about your listening habits — usage history, volume samples, calibration settings — stays on your device. Nothing is uploaded to us or anyone else.

Information HearTime uses

On Android, while tracking is on, a foreground service reads which app is currently playing audio, its volume, and the connected output device (e.g. wired, Bluetooth, speaker) so HearTime can attribute listening time and estimated loudness to that app. This requires Notification Access, which you grant and can revoke at any time in system settings.

On iOS, HearTime reads your headphone audio-exposure samples from Apple Health (read-only) to show real measured listening levels instead of an estimate. iOS doesn't allow apps to see which app is playing audio, so per-app tracking and blocking aren't available there.

During the earphone calibration wizard only, HearTime briefly samples your microphone to measure a relative loudness level for your headphones. That audio is processed in memory and discarded immediately — it is never recorded to a file, saved, or sent anywhere.

HearTime also asks for notification permission, to warn you as you approach your sound budget and to tell you when a lock or break starts.

Where your data lives

All of it — session history, sound budgets, earphone calibration profiles, and settings — is stored in a local database and local preferences on your device. HearTime has no backend server, so there is nowhere for this data to be sent even if we wanted to send it.

Exporting your data

The "Export data" action in Settings copies a JSON summary of your session history to your clipboard, entirely on your device, so you can paste it wherever you'd like — for example, to share with an audiologist. HearTime does not transmit this anywhere on its own.

Third parties

HearTime doesn't include advertising, analytics, or crash-reporting SDKs, and doesn't share data with any third party — there's simply no code path for it to do so.

Your choices

You can turn tracking off at any time in Settings, and revoke Notification Access, Health, or Microphone permission in your system settings whenever you like. Demo mode lets you explore every screen with seeded sample data before granting any permission at all. Uninstalling HearTime removes all of its local data from your device.

Children's privacy

HearTime is not directed at children and does not knowingly collect personal information from anyone — nothing described above ever leaves your device in the first place.

Changes to this policy

If this policy changes, we'll update the effective date above and, for any material change, call it out in the app. The current version always lives at heartime.app/privacy.
