Privacy Policy

Joel Research Corporation — Last updated: June 6, 2026

The short version

Joel Research Corporation does not collect, store, or transmit any personal data from users of its apps. Our apps run locally on your device and communicate only with hardware you own on your local network.

What this policy covers

This policy applies to the Joel Research Corporation website (joelresearchcorporation.com) and to all iOS apps published by Joel Research Corporation, including CAV6 Control.

Information our apps process locally

Our apps process the following on your device only. None of it is transmitted to us:

Network communication

CAV6 Control communicates with Russound® CAV6.6 multi-zone audio controllers via a network-to-serial bridge that you provide on your own local network. No data is sent to Joel Research Corporation, Russound, Inc., or any third party as part of normal app operation.

Apple App Store

When you download our apps from the App Store, Apple may collect data per their own privacy policy. This is governed by Apple, not by Joel Research Corporation. See Apple’s Privacy Policy for details.

Crash reports and diagnostics

If you have Share With App Developers enabled in iOS Settings, Apple may share anonymized crash reports and performance data with us. This data does not contain personally identifiable information. You can disable this at any time in Settings > Privacy & Security > Analytics & Improvements on your device.

Children’s privacy

Our apps are not directed to children under 13 and we do not knowingly collect any data from anyone, including children.

Changes to this policy

If we ever change what data our apps process — for example, by adding a cloud-sync feature — we will update this policy and the “Last updated” date above. Continued use of the apps after a change constitutes acceptance of the revised policy.
