This is the notice the iPhone app shows, word for word, generated from the same text. Updated 26 October 2026.
Nothing. There is no account, no analytics and no advertising. Nobody running IRONWAVE sees what you search for, what you play.
On the iPhone the rate comes from the Health app, with your permission, as your Apple Watch records it. It is used in the app’s memory to show the number, pick a tempo and judge an interval phase, and it is never written to storage, never sent anywhere and never shared with any service. Withdraw the permission at any time in Settings › Health › Data Access & Devices › IRONWAVE. Heart rate is health data; this is the whole of what happens to it.
A search, or building a station, sends the words searched for (artist names, titles) to the services that are switched on. They see those words and the address of the phone asking, the way any site you visit does. Nothing else about you goes with them. Their policies:
Everything the app shows is part of the app or comes from the services above.
IRONWAVE is not directed at children and asks for no information from anyone.
This notice is dated at the top; a change is a new date.
The web app is a free, personal build that can carry more sources than the App Store build. Its notice follows; it differs only in which services it names.
Nothing. There is no account, no analytics and no advertising, and the app sets no cookies of its own. Nobody running IRONWAVE sees what you search for, what you play or how fast your heart beats.
The rate is read from a Bluetooth sensor you choose in the browser’s own device picker. It is used in the page’s memory to show the number, pick a tempo and judge an interval phase, and it is never written to storage, never sent to the app’s server and never shared with any service. Disconnecting the sensor, or closing the tab, is the end of it. Heart rate is health data; this is the whole of what happens to it.

The fonts, the icons and the motion loops are part of the app and come from the same place the page does. YouTube’s player script loads when the app starts; Spotify’s and Apple’s player scripts load only when you sign in to those services.
