Privacy Policy for Echo

Last Updated: September 14, 2026

I (Mark Garrison Jr.) built Echo to listen to radio signals, not to listen to you. Here is exactly how your data is handled.

Section 1

No Tracking, No Ads, No Analytics

I do not know who you are, how you use the app, or what stations you listen to.

No Third-Party Analytics — Echo does not contain Google Analytics, Firebase Analytics, Mixpanel, or any equivalent analytics platform.

No Ads — Echo has no advertising or advertising SDKs. It does not track you across apps or build an advertising profile about you.

Section 2

Your Data is Yours

Echo stores your data on your device.

Echo Pro and iCloud — Echo Pro can sync supported recordings, transcripts, translations, favorites, saved stations, saved servers, notes, and preferences through your private iCloud account.

Your Echo data is stored on your device and, when synced with Echo Pro, in your private iCloud/CloudKit database.

Section 3

Recordings, Transcription & Translation

Recording, transcription, and translation are handled on your device.

On-Device Processing — Transcription uses on-device speech recognition models, and translation uses Apple's on-device frameworks.

Your recordings, radio audio, transcripts, translations, notes, and favorites are not sent to Hugging Face.

Section 4

Connections to Radio Servers

When you connect to a KiwiSDR, OpenWebRX, WebSDR, or FM-DX Webserver, your device makes a direct connection to that independently operated server.

IP Addresses — The server operator may see your public IP address and ordinary connection information in its logs.

Independent Servers — Echo does not control these servers or their logging practices. It sends only what is needed to make and use the radio connection you requested.

Section 5

Speech Model Downloads

Echo downloads the speech recognition models used for transcription from Hugging Face.

Like any internet service, Hugging Face may receive your IP address and ordinary technical information about the download. Its handling of that information is governed by its own privacy practices.

Hugging Face provides the model files. Your radio audio is processed on your device and is never sent to Hugging Face.

Section 6

Location Data

Echo may ask for your location to show you the distance to radio servers.

On-Device Only — Your location is used on your device to calculate that distance. Echo does not upload or share your precise location.

Section 7

Deleting Your Data

Deleting Echo removes the app's local data from that device.

iCloud Sync — Content already synced with Echo Pro may remain in your iCloud account. When you delete synced content inside Echo, that deletion is also reflected across your synced devices through iCloud.
