HearRelay (“the App”) is designed to be private by default. This policy explains what data is, and is not, processed when you use HearRelay.
If you have any questions, please contact us at hearrelay-privacy@conex-cp.com.
HearRelay is developed by CONEX Corporation (株式会社CONEX), a company incorporated in Japan (“the Developer”, “we”, “us”). Because HearRelay processes no personal data on our servers, we do not act as a “data controller” in any meaningful sense — we are the app’s publisher. For correspondence, please use the email addresses at the bottom of this page.
We do not collect, store, transmit to our servers, or share any of the following:
HearRelay does not contain any third-party SDKs for analytics, advertising, or tracking.
The App processes the following on your device, and only on your device:
| Data | Purpose | Retention |
|---|---|---|
| Microphone audio (live) | Real-time monitoring to headphones or to a paired device on the same Wi-Fi | Not stored |
| Audio recordings (optional) | You can record sessions manually | Deleted automatically after 24 hours by default; you may extend or delete earlier |
| Connection history (peer name, last connected time) | Convenience feature to reconnect quickly | Stored locally; cleared when you uninstall the App |
| App preferences | Remember your settings | Stored locally |
When you uninstall the App, all of the above data is removed with it.

HearRelay communicates only with other Apple devices that are:
Communication is encrypted with TLS 1.3. HearRelay does not send any data over the internet to remote servers, nor does it support remote monitoring across networks. Remote use is deliberately prohibited to prevent covert surveillance.

Because HearRelay does not transfer data out of your devices, there is no international transfer of personal data performed by us.
HearRelay is a utility intended for adults, typically parents or caregivers. It is not directed at children under 13, and we do not knowingly collect personal data from children. The App’s processing is local to your device, so no personal data of children is collected, stored, or transmitted.
Because we hold no personal data about you, there is typically nothing for us to access, correct, delete, export, or restrict. Nevertheless, depending on your location (EEA, UK, California, Brazil, Japan, etc.), you may have statutory rights, including:
To exercise any right, contact us at hearrelay-privacy@conex-cp.com. Please note that to delete all data the App has stored locally, you only need to uninstall the App from your device.

We may revise this Privacy Policy. The revision date will be updated at the top of this page, and material changes will be announced in the App’s release notes. Continuing to use the App after changes take effect constitutes acceptance.
