Privacy Policy

Effective October 6, 2026

Axsen (“the app”) is a sensor and hardware information viewer that runs entirely on your device. The principle is simple: the app does not collect, upload, sell or share any personal data.

We collect no data

The app contains no networking code, no accounts, and no advertising, analytics, crash reporting or third-party SDKs. The developer has no access to anything you see in the app.

Information read on your device

To show readings on screen, the app reads the following on your device. Readings are kept in memory only, sampling stops when the app goes to the background, and everything is discarded when the app closes. Nothing is written to files or leaves your device.

InformationPurposePermission
Location: coordinates, altitude, speed, headingGNSS location and compass on the Sensors tabLocation “While Using the App”; you can decline
Motion & Fitness: steps, activity, air pressureSteps, floors, activity type, barometric altitudeMotion & Fitness; you can decline
Accelerometer, gyroscope, magnetometerAttitude gauges and raw sensor chartsNone
Advertisements from nearby Bluetooth Low Energy devicesName, signal strength and manufacturer after you tap “Scan Nearby Devices”. The app never connectsBluetooth, requested only when you start a scan
Network status, interface addresses, traffic counters, cellular radio technology, audio routeNetwork and audio information on the Connectivity tabNone
Model, chip, memory, storage, battery, CPU load, boot timeHardware and system status on the Device tabNone

Settings stored on your device

The app keeps a few interface preferences locally, such as which detail sections are expanded, how the Bluetooth list is sorted and filtered, and whether a hint banner was dismissed. They contain no personal information and are removed when you delete the app.

Shared images

The app creates an image of the current readings only when you tap Share. By default precise location is hidden, with coordinates rounded to about 1 km, and so are IP addresses and Bluetooth and audio device names. You decide where the image goes through the system share sheet. Saving to Photos asks for “Add Photos Only” access; the app never reads your photo library.

Managing permissions

You can change these permissions at any time in Settings › Privacy & Security, or in Settings › Axsen. Declining a permission only hides the related section; everything else keeps working.

This website

axsen.app uses no cookies, analytics or tracking scripts. The site is hosted on Cloudflare, which processes standard request data such as IP addresses to deliver and protect the site. The bubble level on the home page reads your device’s motion sensors inside the browser only after you allow it, and those readings are never transmitted.

Children’s privacy

The app collects no personal information from anyone, including children under 13.

Changes to this policy

If this policy changes, this page and its effective date will be updated. If a future version handles data differently in a material way, the App Store release notes will say so.
