Privacy Policy

Effective date · June 14, 2026

01 — Who we are

VoidMic is developed and published by Julien Bayle, operating under the name Structure Void, based in Marseille, France. For any privacy-related question, contact voidmic@structure-void.com.

02 — What data the app processes

VoidMic processes the following data, and only the following data:

• Microphone audio, captured from your device when you tap Start and stop being captured the moment you tap Stop or close the app. Audio is processed in memory only.
• Peer name, a label you choose for your device (default: the device model). Stored locally on your device using Android DataStore. Never transmitted off your network.
• Network broadcast packets, technical messages used by the Ableton Link Audio protocol to advertise your device's presence and audio channel to other peers on your LAN.

The VoidMic Android app does not collect: your name, email, account, contact list, location, IP address (beyond what's needed to talk to other peers on your LAN), device identifier, advertising ID, usage analytics, or any personally identifiable information. (Aggregate, anonymous website analytics on the landing page are described in section 07.)

03 — Where your audio goes

Microphone audio captured by VoidMic is transmitted exclusively to peers on your local Wi-Fi network via the Ableton Link Audio protocol (UDP, with multicast for peer discovery). It does not pass through any server we operate, any cloud service, or any third party. We have no infrastructure that receives or stores your audio.

If you turn off Wi-Fi, the stream stops. If no peer on your network subscribes to the channel, the audio packets are not received by anyone.

04 — Permissions explained

• Microphone (RECORD_AUDIO): required to capture the audio you want to stream. Only used while you are actively streaming.
• Network and Wi-Fi state (INTERNET, ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE, CHANGE_WIFI_MULTICAST_STATE): required to send audio and discovery packets on your local network. The Internet permission is the Android name for any socket, including LAN-only ones. VoidMic does not contact any remote server.
• Foreground service (FOREGROUND_SERVICE, FOREGROUND_SERVICE_MICROPHONE): required so the audio keeps streaming when your screen is off or the app is in the background. Android shows a persistent notification while this is active, so you always know streaming is on.
• Wake lock (WAKE_LOCK): required to prevent the CPU from sleeping while streaming.
• Notifications (POST_NOTIFICATIONS): required on Android 13+ to display the persistent streaming notification with a Stop action.

05 — Data storage and retention

VoidMic does not store recorded audio at any point. Audio is processed in real time and discarded as soon as it leaves the device. The only persistent data is your chosen peer name, stored locally on your device. Uninstalling the app removes it.

06 — Third parties

VoidMic uses the open-source Ableton Link library by Ableton AG to handle peer discovery and timing on the local network. This library runs entirely on your device and does not transmit data to Ableton or any other server. We do not embed any analytics SDK, advertising network, crash reporter that transmits off-device, social login, or tracking pixel. The only analytics anywhere in the project is the self-hosted, first-party website analytics described in the next section — it runs on our own server, not as a third-party SDK, and is not present in the app.

07 — Website analytics

The VoidMic landing page (voidmic.structure-void.com) uses Umami, a privacy-respecting, self-hosted analytics tool running on our own server (stats.structure-void.com). It records aggregate, anonymous visit data such as page views, referrer, browser type, and country, to help us understand traffic. It does not use cookies, does not collect personal data, does not track you across other websites, and does not build a profile of you. No data is shared with any third party. This applies to the website only. The VoidMic Android app itself contains no analytics of any kind and does not phone home.

08 — Children's privacy

VoidMic is not directed at children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect data from children. Because the app processes only on-device audio and does not collect identifying information, no child-specific data could be transmitted.

09 — Your rights under GDPR

If you are a resident of the European Union, the United Kingdom, or another jurisdiction with similar privacy laws, you have the right to access, correct, delete, or restrict processing of your personal data. Since VoidMic does not collect or store personal data off your device, there is nothing for us to retrieve or delete on our side. For any question, contact voidmic@structure-void.com.

The legal basis for the processing performed by the app (microphone capture and LAN audio transmission) is the performance of the service you explicitly initiate by tapping Start.

10 — Security

Because audio stays on your local network and is not transmitted to any server we operate, the security of your stream depends on the security of your Wi-Fi network. We recommend using a password-protected Wi-Fi network. The Ableton Link Audio protocol does not encrypt audio packets on the LAN; any device on the same network can subscribe to a published channel. Use VoidMic on trusted networks.

11 — Changes to this policy

If we make material changes to this policy, we will update the effective date above and, where appropriate, notify users through the Google Play store listing.
