Introduction

ALGSoft Inc. ("we," "our," or "us") built Digi Voice as a commercial amateur radio digital voice communication application. This Privacy Policy explains how we handle information in connection with your use of the Digi Voice app on iOS, macOS, and watchOS devices.

Digi Voice is intended for licensed amateur radio operators. Use of this application requires a valid amateur radio license issued by your country's telecommunications authority.

Digi Voice Collects No Data

Your Callsign, DMR ID and Passwords Belong to Third-Party Platforms

Your callsign and DMR/NXDN ID are credentials you registered on RadioID.net, BrandMeister, TGIF, or another radio network — independently of Digi Voice. Digi Voice does not issue, register, store, or manage these credentials on its own servers.

When you enter your callsign and password in the Settings screen, that information is saved only on your local device and sent directly from your device to the third-party server you select. We never receive it.

Configuration Stored Locally on Your Device

The following fields are stored only on your device. They are not "collected" by us — we never see them:

Diagnostic Log Files

The app writes session logs to the device's Caches directory (not iCloud-synced). Logs contain connection events, handshake status, audio engine status, GPS acquisition status, and error messages. Logs are stored locally and are never transmitted to us or any third party automatically.

How We Use Your Information

Your information is used exclusively to operate the application's core radio communication features:

• 🔐
  Protocol Authentication

  Callsign, digital ID, ESSID, and password are included in protocol handshake packets sent to the server you select.
• 📍
  Position Reporting

  Coordinates you enter or retrieve via GPS are included in protocol configuration packets. This is standard in DMR/BrandMeister/TGIF protocols.
• 🔍
  Callsign / ID Lookup

  When you tap the ID lookup button, your callsign is sent to radioid.net via HTTPS to retrieve your registered DMR or NXDN ID.
• 🎙️
  Voice Transmission

  Microphone audio is encoded and transmitted in real time to the radio server for the duration of PTT activation.

Information Shared with Third Parties

We do not sell, rent, or commercially share your personal information. The following limited sharing occurs as a direct result of the application's radio network functionality.

Radio Network Servers

When you connect to a network server, the following data is transmitted directly from your device to the server operator you choose — not through our infrastructure:

RadioID.net

When you use the Digital ID lookup feature, your callsign is transmitted to https://radioid.net via HTTPS. Please refer to their privacy policy at radioid.net.

Device Permissions

• 🎙️
  Microphone — Required for PTT

  Requested on first PTT attempt. Audio is captured only while PTT is active and is transmitted exclusively to the radio server you are connected to. The app does not record audio to a file.
• 📍
  Location (When In Use) — Optional

  Requested only when you tap "Get GPS Location." Uses requestWhenInUseAuthorization() — background location is never requested. Location service stops immediately after coordinates are retrieved.
• 🌐
  Local Network — For local hotspot connections

  Required to allow UDP connections to DMR hotspot devices on your local Wi-Fi network. Does not grant access to files or data on other devices.

Data Security

All settings, including passwords, are stored using UserDefaults on your local device, protected by iOS/macOS Data Protection and your device's passcode or biometrics.

Passwords are transmitted to network servers in the format required by the protocol: DMR uses a SHA-256 hash; other protocols may transmit within the UDP payload. We recommend using network-specific hotspot security keys rather than primary account credentials.

Data Retention and Deletion

Settings: Stored indefinitely until you reset or delete the app. Delete Digi Voice from your device to remove all settings.

Log Files: Stored in the Caches directory. The OS may delete them under storage pressure. You can clear logs manually from the Logs tab. All logs are removed when the app is deleted.

Children's Privacy

Digi Voice is intended for licensed amateur radio operators and is not directed at persons under the age of 13 (or the applicable minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has used this application without appropriate supervision, please contact us.

International Users

Digi Voice is developed in Türkiye. All data you enter is stored locally on your device. When you connect to radio network servers, your data is transmitted to servers operated by third parties in various countries. By using network features, you consent to this cross-border transmission as part of the radio network operation.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last Updated" date and, where appropriate, provide notice within the application. Continued use of Digi Voice after the effective date of a revised policy constitutes your acceptance of the changes.

Your Rights and How to Exercise Them

Because Digi Voice holds no personal data on its own servers, how you exercise data rights depends entirely on where the data actually lives.

Data Inside the Digi Voice App (on your device)

• 👁
  Access / Export

  Read all settings directly in the Digi Voice Settings screen — everything is visible to you.
• ✏️
  Rectify

  Edit any field in the Settings screen at any time, directly in the app.
• 🗑️
  Erase

  Delete the Digi Voice app from your device. All UserDefaults and cached log files are permanently removed. There is nothing to request from us — we hold no copy of your data.

Data on Third-Party Radio Network Platforms

Your callsign, DMR ID, account profile, and transmission history are held by the platforms you registered with. Digi Voice has no access to this data and cannot modify or delete it on your behalf. Contact those platforms directly:
