Terms & Privacy
1. What this app does
Hertz & Health uses your device's microphone to estimate sound pressure levels and compute a model of Temporary Threshold Shift (TTS). It is designed to help you understand your acoustic environment and make informed decisions about your hearing health.
2. Not a medical device
Hertz & Health is not a medical device and is not intended to diagnose, treat, or prevent any medical condition. The measurements and health indicators it provides are estimates based on a computational model. Do not make clinical decisions based on data from this app. If you have concerns about your auditory health, consult a qualified audiologist or medical professional.
3. Accuracy limitation
Measurement accuracy depends on your device's microphone calibration. Results may vary significantly between devices. The app may underestimate or overestimate actual sound pressure levels. Calibrating the app in the calibration settings improves accuracy but does not guarantee professional-grade results.
4. Microphone access
This app requires microphone access to function. Audio is processed entirely on your device. We do not record, store, or transmit raw audio to any server.
5. Data we collect
When the app crashes, diagnostic data (crash logs, device model, OS version) is sent to our crash reporting service to help us fix bugs. No personally identifiable information is included.
Other data we collect includes: device model, OS version, app version (during bug reports done by the user), phone manufacturer, model, board name, calibration method, method of calibration, and an anonymous install ID (during submission of calibration data by the user).
Before collecting any data, the app will ask for your explicit consent and explain what is being sent.
6. Your health data
Health data generated by this app is stored locally on your device only. You can delete it at any time in Settings → Clear Data. We do not upload your health data.
7. Changes to these terms
We may update these terms as the app evolves. If the terms change materially, you will be asked to review and accept them again before continuing to use the app.
8. Contact
For questions, feedback, or bug reports, use the Feedback screen inside the app or contact us by email: hzandhealth@gmail.com
