Privacy
FM One Privacy Policy
Effective November 3, 2026
We don't track you or share your personal data. The FM One app has no account or advertising. It counts anonymous usage and sends crash reports so we can improve it, and you can turn both off.
What stays on your device
Your channels, radio settings, frequency cards and profile name are saved only on your device. They aren't sent to us.
Anonymous analytics
FM One uses TelemetryDeck to count how the app is used, such as which radios, lessons, Explore cards and tools are opened and how Practice sessions score. Each count includes an anonymized ID for this installation, a timestamp rounded to the hour, and device details such as the system version, app version and device type. It never includes your channels, frequencies, tones, names or profile contents. TelemetryDeck says it doesn't store IP addresses. To turn this off, open the menu, choose About FM One and turn off Share Analytics. No analytics or crash reports are sent while it's off.
Crash reports
If FM One crashes, it sends a report to Sentry with technical details such as the code involved, the app version and device type, and anonymous session counts. Reports don't include screenshots, your channels, frequencies, tones, names or profile contents. Share Analytics turns these off too.
Sharing a profile
If you choose to share a profile, FM One creates a file with your channels, settings, frequency cards and the profile name you entered. It goes only where you send it, using AirDrop, Messages, Mail, Files or another option you pick. We never receive it.
Library links
The Library links to documents on other websites, which open in your browser. Those sites have their own privacy policies.
This website
This website uses no cookies or analytics of its own. It's hosted by GitLab, which may keep standard server logs under its own privacy policy.
If you email us, we'll use your message and address only to reply.
Reporting a problem
Report a Problem opens an email to us with what you wrote and details of the radio you were using: the screen it was on, the selected channel and its frequencies, your app version and your device model and iOS version. You can read it and change it first, and nothing is sent until you send it. If you choose to, you can also attach all your channels and frequency cards. We use these only to look into the problem.
Children
FM One doesn't knowingly collect personal information from children.
Changes
If this policy changes, the new version will be posted here with a new effective date.
