Privacy Policy

Last updated: May 1, 2026

Overview

VoxDMR is software for connecting to DMR talkgroups on BrandMeister and other DMR networks. This policy explains what data the app stores and what network connections it makes.

Data Collection

VoxDMR does not collect, store, or transmit any personal data to the developer or any third party. The app contains no analytics, advertising, or tracking of any kind.

Data Stored on Your Device

The app stores the following data locally on your device only:

  • Configuration: DMR ID, hotspot password, server address, talkgroup settings, and PTT key binding. Stored in ~/.config/voxdmr/
  • App preferences: audio device selection, PTT mode, UI preferences

This data never leaves your device except when connecting directly to the DMR servers you've configured.

Microphone

VoxDMR accesses your device microphone solely for push-to-talk voice transmission to the DMR servers you connect to. Audio is encoded using the AMBE+2 codec and sent directly to the server you are connected to. Audio is not recorded, stored, or transmitted elsewhere.

Network Communication

VoxDMR makes the following network connections:

  • Rewind/UDP: real-time audio and control to the DMR servers you configure
  • HTTPS (first launch only): firmware download from md380.org and GitHub, SHA-256 verified. Only triggered when you click "Download" during setup.

No other network connections are made. There is no telemetry, no update check, and no cloud service.

Third-Party Services

VoxDMR does not use any third-party services, SDKs, or APIs beyond the DMR networks you connect to and firmware download sources. There are no ads, analytics, crash reporting, or cloud services.

DMR Networks

VoxDMR connects to DMR servers (BrandMeister and other DMR networks) operated by independent parties. The developer of VoxDMR does not operate, control, or moderate these servers. Communication through these servers is real-time voice between connected users.

Children

VoxDMR is not directed at children under 13. The app requires a licensed amateur radio DMR ID to operate.

Changes

This privacy policy may be updated. Changes will be posted at this URL with an updated date.
