Privacy policy
Last updated: 17 October 2026
This policy covers the livematrix apps: the client on iPhone, iPad, Apple Watch, Android, Windows, macOS, Linux and in the browser, and the server and bridge software. livematrix is made by livemotion gmbh, Bolacker 1, 4563 Gerlafingen, Switzerland (“we”).
In short
Section titled “In short”- livematrix is intercom software that your organization runs on its own server. Your voice, your sign-in and your settings go to that server, not to us.
- The apps contain no advertising, no analytics, no tracking and no crash reporting. We do not sell or share personal data.
- The app does not record audio. It streams your voice live and keeps nothing.
Who is responsible
Section titled “Who is responsible”The organization that runs your livematrix server, usually your employer or the production you work on, decides who has an account and what happens on its server. For data on that server it is the responsible party (the controller). Ask it about the data it keeps, how long it keeps it, and who can see it.
We are responsible only for the few services we run ourselves, listed under Services we run.
What the app sends to your server
Section titled “What the app sends to your server”When you sign in, the app sends your server:
- your username and password;
- a random device ID the app creates when it is installed, which tells your devices apart;
- the device’s name and model, so you and your administrator can see which device is connected;
- your audio settings and which keys you press;
- your IP address, as every internet connection does.
While your microphone is on, the app streams its audio to your server, which passes it only to the people and lines you talk to. The audio is encrypted on the way (DTLS-SRTP), as is the rest of the connection when the server uses HTTPS. Neither the app nor the server records it.
If a direct connection is not possible, the audio may pass through a relay (TURN) server that your server’s administrator chose.
What stays on your device
Section titled “What stays on your device”The app stores, in its own private storage on the device:
- the servers you added, with your username and, if you choose to stay signed in, your password. Disconnecting removes the password;
- your device ID and your settings;
- a connection log of the last 2,000 connection events (connected, reconnecting, network changes). It contains no audio and no passwords. It leaves the device only if you export it under Settings › Diagnostics and send it to someone yourself.
Uninstalling the app deletes all of it.
Permissions
Section titled “Permissions”| Permission | What it is for |
|---|---|
| Microphone | To talk. The app uses the microphone only while you are connected. |
| Camera (iPhone and iPad) | Never used. iOS requires the entry because the audio library the app uses contains camera code. |
| Local network (iPhone and iPad) | To reach a livematrix server on your local network. |
| Bluetooth (Android) | To use Bluetooth headsets. |
| Notifications (Android) | To show that a session is running. Refusing hides the notification and nothing else. |
| Running in the background (Android foreground service, iOS background audio) | To keep talking and listening with the screen off or while you use another app. |
| Ignore battery optimisation (Android) | Asked only if you choose it in Settings, so that Android does not cut a session in the background. |
The app does not use your location, contacts, photos or camera.
Services we run
Section titled “Services we run”A few connections reach servers that we, livemotion gmbh, run:
- Connection helper (STUN). If your server names none of its own, the app
asks
stun1.livematrix.iofor its public IP address, which it needs to set up the audio connection. The helper sees that address and nothing else, and we use it for nothing else. - Secure access relay. If your administrator uses a livematrix hostname
(for example
yourname.livematrix.app), the app’s connection to your server passes through our relay. The relay forwards the connection, sign-in included, and stores none of it. It keeps counts of connections without IP addresses, and records an IP address only briefly when it has to diagnose a failed connection. The audio does not pass through it. - Update checks (Windows, macOS and Linux). The desktop client asks
console.livematrix.ioevery six hours whether a newer version is out. The request carries the app’s version and your IP address, nothing about you. Set Settings › Updates to Off to stop it. The phone apps update through the App Store and Google Play.
The app stores
Section titled “The app stores”Apple and Google, who distribute the apps, may collect data of their own, for example about downloads and crashes, under their own privacy policies. We see only the summaries they show developers, which do not identify you.
Children
Section titled “Children”livematrix is for professional productions and not meant for children under 16. We do not knowingly collect data from children.
Your rights
Section titled “Your rights”Under the Swiss Federal Act on Data Protection and, where it applies, the EU General Data Protection Regulation, you may ask what data is held about you and have it corrected or deleted. For data on your organization’s server, ask your administrator. For data we hold, write to us at support@livematrix.io. You may also complain to a data protection authority, in Switzerland the Federal Data Protection and Information Commissioner (FDPIC).
Changes
Section titled “Changes”When this policy changes, we update this page and the date at the top. If a change affects what the apps send, we say so in the release notes.
