myNIFOG collects no personal data. There are no accounts, no analytics, no advertising, no third-party tracking SDKs, and no server operated by the developer. Nearly everything the app does — all reference content and all coverage computation — happens entirely on your device.
We do not collect, store, sell, or share your name, email, contacts, identifiers, usage analytics, or any personal information. The app has no login and no user profile.
The app makes network requests in exactly two user-initiated situations, both over encrypted HTTPS:
We do not receive or log any of these requests — they go directly from your device to those public services. Please review the privacy practices of AWS and the OpenStreetMap Foundation for how those services handle requests.
If you use the “Around me” option in the offline data manager, the app reads your device location once, on demand, solely to choose which terrain tiles to download around you. Your location is never stored beyond that moment and is never transmitted to us or to anyone else. If you deny location permission, the feature simply falls back to a default area.
The app stores your preferences (edition, night mode, units, starred items) and any terrain you download in the app’s private storage on your device. This data never leaves your device except through your own device backups, and can be removed by deleting the app.
myNIFOG is a professional reference tool and is not directed to children. It collects no data from anyone, including children.
If this policy changes, the updated version will be posted here with a new effective date.

myNIFOG is an independent application and is not affiliated with, sponsored by, or endorsed by CISA, FEMA, or the U.S. Department of Homeland Security. Coverage estimates are statistical planning aids, not a guarantee of radio coverage.
Frequencies, tones (CTCSS/DCS), NAC codes, and other channel parameters presented in this application may contain errors or may have changed since publication of the source documents. Verify all frequencies, tones, and channel parameters against authoritative sources and confirm with radio checks before operational use.
Information in this application regarding frequency licensing, authorization, and permitted usage may be incomplete, outdated, or inaccurate. Many frequencies referenced in the NIFOG and AUXFOG require an FCC license, NTIA authorization, agency approval, or specific eligibility to transmit. All channels — whether licensed, license-free, or federally managed — are subject to operational and technical constraints, which may include transmit power limits, antenna height and equipment restrictions, geographic limitations (including restrictions near the Canadian and Mexican borders), permitted emission modes, and license-class privileges. A license or authorization permits operation only within its specific terms. You are solely responsible for verifying all licensing, authorization, and technical requirements and for ensuring compliance with all applicable laws and regulations, including FCC rules and NTIA regulations governing federal spectrum, before transmitting on any frequency. The developers of this application assume no liability for unauthorized or non-compliant transmissions or for any harmful interference caused by your use of the information provided.
Good operating practice requires monitoring a channel before transmitting to confirm your transmission will not disrupt ongoing communications, and immediately ceasing operation if you learn your transmission is causing interference or other harm.
