Privacy Policy
Effective: October 16, 2026
AXIRN (“the app”) is a sensor instrument for iPhone and iPad. It reads your device's sensors and shows the readings on your screen. This policy explains what the app reads, where that data goes, and what stays on your device.
The short version
- Nothing you see in AXIRN is sent to us. We do not run servers, and the app has no account, analytics, advertising, crash reporting, tracking or third-party SDKs.
- Your readings stay on your device. They are processed in memory while a screen is open and are not uploaded.
- AI runs on the device only. When Foundation Models (Apple Intelligence) is available, questions and the readings you attach go to Apple's on-device language model and never leave the device. No cloud model is used.
- The one exception is weather. To show the forecast, Apple's WeatherKit service receives your location from the device. Apple handles that request under its own privacy policy.
What the app reads, and what happens to it
Every source is used only while you use it, and each one can be switched off in Settings › Data Access.
| Source | What is read | Where it goes |
|---|---|---|
| Motion, compass, barometer, orientation | Accelerometer, gyroscope, magnetometer, attitude, heading, pressure, altitude | Shown on screen; kept in memory only |
| Motion & Fitness | Pedometer counts and the activity Core Motion recorded over the last 7 days | Shown on screen; daily totals may be saved on the device for the widget |
| Location | Coordinates, altitude, speed, accuracy | Shown on screen; sent to Apple WeatherKit only when the Weather screen or row needs a forecast |
| Camera | Live preview frames for Camera Feed, Attitude, Face Detection, Face Tracking and LiDAR | Processed live; never recorded, saved or uploaded |
| Microphone | Input level (loudness) only | Processed live; no audio is recorded, saved or uploaded |
| Bluetooth | Advertisements from nearby Bluetooth LE devices: name, signal strength and advertised codes | Kept in memory and dropped 30 seconds after a device goes silent; the app never connects to devices |
| Health (read only) | Heart rate, steps, sleep, workouts, VO₂ max, blood oxygen | Shown on screen; daily values may be saved on the device for the widget. The app never writes to Health |
| Battery and device state | Charge level, charging state, thermal state | Shown on screen |
| Speech | What you say, only while the Speech screen is open | Transcribed on the device to show the text and to open a sensor you name. Audio is not recorded, saved, or uploaded. If the on-device speech model for your language is not installed, iOS downloads that model from Apple |
| Siri | Permission status only | Nothing is recorded |
The app asks for each permission when you open the screen that needs it, or when you tap Allow in onboarding or Data Access. You can change any permission at any time in iOS Settings.
On-device AI (Foundation Models)
The Foundation Models screen uses Apple's on-device system language model when your device supports Apple Intelligence and it is turned on.
- Your question and, only when the READINGS switch is on, the current live readings are sent to the on-device model. The exact lines that were sent are shown under your question.
- The model runs on your device. Requests are not sent to us, to Apple's servers or to any other service.
- The conversation is held in memory and cleared when you tap Clear or leave the screen.
- If the model is not available, the screen says why and nothing is sent.
What is stored on your device
- Settings: appearance, units, sounds, Data Access switches, alert rules, dashboard pins, the widget source, onboarding status and the model prompt.
- Widget data: the latest slow readings for the chosen widget source and up to seven daily totals, kept in an App Group container shared only with AXIRN's own widget.
This data does not leave the device through the app. It may be included in your own iCloud or computer backup of the device, under Apple's terms. Deleting the app deletes it. Data in Apple Health stays in Health.
Notifications
Alerts (for example, battery below a threshold) are local notifications created on the device while the app is open. No notification server is used.
Apple services
The app relies on Apple frameworks that process data on the device. WeatherKit (Apple Weather) receives your location to return weather data. The Speech screen transcribes on the device; the only related network request is iOS downloading a missing speech model from Apple, and that download does not include what you said. See Apple's privacy policy at https://www.apple.com/legal/privacy/ for how Apple handles those requests.
Children
The app does not knowingly collect personal information from anyone, including children, because it collects no personal information at all.
Changes
If this policy changes, the new version will ship with an app update and show a new effective date. A change that sends data off the device would be described here before it ships.
