marine radio, anywhere — privacy & acknowledgements

Last updated: 17 June 2026

Privacy

MyNarwhal is a listen-only marine-radio app, built to collect as little as possible.

No account, no sign-up, no ads, no tracking. No analytics, cookies, or third-party trackers.
No device permissions beyond internet. The app doesn't access your location, microphone, contacts, or files. The map shows receivers and ships; it never reads your GPS.
Stays on your device. Your settings (such as a custom relay address) are stored locally on your device and are not sent to us.
Sent to our relay. The map area you're currently viewing (a box of latitude/longitude, so we can show ships near that view) and your audio-playback requests. This isn't tied to any identity.
Server logs. Our relay and our network provider (Cloudflare) may keep standard technical logs — such as IP address and request times — briefly, to operate the service and prevent abuse. These are not used to profile you.
Third-party content. Audio is streamed from volunteer-run public receivers (KiwiSDR, OpenWebRX, WebSDR) operated by others; ship positions come from aisstream.io; maps from OpenStreetMap and CARTO. Your use of that content is also subject to those operators' terms.
Children. The app is not directed at children and collects no personal data.
Changes. Any updates to this statement will be posted on this page.

MyNarwhal stands on the work of volunteer receiver operators and open data & software. Thank you:

Receiver operators running KiwiSDR, OpenWebRX and WebSDR receivers worldwide — the audio comes from them. Please support the receivers you use.
VHF feed — VC Brandaris (Terschelling, NL).
Receiver directories — the public KiwiSDR list and receiverbook.de (OpenWebRX).
Ship positions (AIS) — aisstream.io.

MyNarwhal is free and community-supported, not commercial. It is listen-only and does not transmit.
