Privacy Policy

1. Introduction

This Privacy Policy explains how Hearing FullSpeed ("we", "our", "the App") handles your information when you use our mobile application. We take your privacy extremely seriously.

By using the App, you agree to the practices described in this policy. If you do not agree, please do not use the App.

2. Zero Data Collection

We collect absolutely nothing.

• No servers. The App operates entirely on-device. There are no backend servers, no cloud storage, and no remote databases.
• No accounts. You do not need to register, log in, or create an account.
• No tracking. No analytics SDK, no crash reporting SDK, no advertising SDK, no fingerprinting, no cookies.
• No data transmission. All audio processing happens in real time on your device. Your audio never leaves your phone.
• No persistent storage of audio. Sound is processed in volatile memory and destroyed instantly.

0-byte privacy guarantee: We record zero bytes of your data. We store zero bytes. We transmit zero bytes.

3. Microphone Permission

The App requires microphone access solely for real-time audio processing to provide hearing assistance (amplification, noise reduction, equalization).

• Audio is processed locally and in real time using our native C++ audio pipeline.
• No audio is recorded, saved, or transmitted.
• You may revoke microphone permission at any time via your device's system settings.
• If you revoke permission, the hearing assistance features will stop working, but the App will continue to function for other purposes.

4. No Medical Use

Important: This App is NOT a medical device.

Hearing FullSpeed is a lifestyle and entertainment audio calibrator. It is not intended to diagnose, treat, cure, or prevent any disease or medical condition, including hearing loss. Always consult a qualified healthcare professional for medical advice.

5. Third-Party Services

The App does not integrate any third-party analytics, advertising, or tracking services. The only network request the App makes is to check for software updates (if enabled) — no personal data is included in such requests.

6. Children's Privacy

The App is not directed at children under the age of 13. We do not knowingly collect any personal information from children.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted within the App. Your continued use of the App after changes constitutes acceptance of the updated policy.
