How the app handles your data.

The short version

• No account, sign-in, advertising, or crash-reporting library in the app. The app does not send usage analytics. The web test build keeps local usage measurements as described below.
• Your app records are stored on your device. They are not automatically uploaded to us. If you send us an export or screenshot, we receive the information it contains.
• Network requests: the weather-station lookup sends your coordinates to the U.S. National Weather Service. Catalog downloads contact a server hosted on GitHub Pages. Both services receive your IP address and request metadata. These requests do not include your saved rifle profiles or shot logs.
• You can export your records, delete saved location data in Settings, and remove local app data by deleting the app. Exported files, support correspondence, and beta feedback are separate copies.

Who we are

American Marksman Ballistics is published by American Marksman Company Inc., Volusia County, Florida, USA (“we”). The app is titled American Marksman on your phone. Questions about this policy go tosales@PrecisionRifleworks.us.

What the app stores on your device

Everything you enter or measure lives in the app’s private storage on your phone (or, for the web build, in your browser’s storage):

• Rifle profiles: name, scope and click value, zero distance, sight height, barrel twist, and the scope-check results you save.
• Ammunition and loads: the projectile, the ballistic coefficient and its model, and the muzzle speed you entered or measured, with a label saying which.
• Shots and range cards, including the conditions at the time and, if you had the weather-station feature on, the coordinates used for it.
• Live-fire calibration records and their verification history.
• Settings: units, display mode, text size, teaching level, and which devices you have saved for reconnection.
• A cached copy of the projectile catalog and its trust metadata.

The app does not automatically upload these records to us or sync them through a cloud account. Coordinates used for a weather lookup are sent as described below. You may also choose to share records in an export or a support message.

Weather and catalog requests

1. Coordinates, to the National Weather Service

When you turn on Position and the nearest weather station, the app asks for permission to use your location while you use the app. It then sends your latitude and longitude to api.weather.gov, a service of the U.S. National Weather Service (part of NOAA), to find nearby observation stations and read their latest temperature, pressure, and humidity. NOAA receives your coordinates, your IP address, and the app’s standard request headers, and handles them under theweather.gov privacy policy.

The app does not send coordinates for weather lookups in the background or while the feature is off. Your latitude is also used on the phone itself for the earth-rotation allowance in the firing solution. Coordinates saved with shots and conditions can be deleted at any time with Delete saved location data in Settings; rifles and the rest of each shot stay intact.

2. Catalog updates, from our catalog server

The app periodically downloads the signed projectile catalog from our catalog server on GitHub Pages. The catalog is a public file of projectile identities, masses, diameters, and drag values. It contains no personal data. GitHub receives the request, including your IP address and standard request metadata, underGitHub’s privacy statement. The request does not include your saved rifle profiles or shot logs. If the download fails, the app keeps using the last good copy.

Analytics and advertising

There is no analytics, advertising, or crash-reporting library in the app. Beta-distribution services and information you send us are described separately below. We update this policy when the app adds a request or changes how it handles data.

Permissions and sensors

Location (while using the app)

Used only for the weather-station lookup described above and for the earth-rotation latitude. On iPhone, the compass heading is also read on the phone to capture shot direction when you ask for it. The app never uses location in the background.

Bluetooth

Used only to connect to devices you choose — a rangefinder, a chronograph, or a weather meter. Readings feed the firing solution and are stored with the shot on your phone. The app talks to the device directly; it does not sign in to any device maker’s cloud service. On Android, a device session uses a persistent notification. Keeping devices connected through screen lock and app switches is still under test on iPhone and Android and should not be relied on.

Motion and barometer

The phone’s barometer measures air pressure at the firing line. Motion data is used on the phone to judge whether the compass reading is steady. Nothing is transmitted.

Notifications (Android)

Only for the “device connected” notice that Android requires while a device session runs. The app sends no other notifications.

Garmin watch bridge (Android, optional)

If you install the optional watch app, the current solution is passed to the Garmin Connect app on your phone so it can be shown on your watch. That app belongs to Garmin and is covered by Garmin’s own privacy policy.

You can revoke any permission in your phone’s settings. The related feature stops; the rest of the app keeps working.

Files you export

Download my data writes a single file containing your rifles, loads, shots (including any saved coordinates, unless you deleted them), calibration history, and settings. You choose where the file goes and who sees it; anyone you share it with can read it.Restore reads a file you pick. Export and restore do not automatically send us a copy.

The web test build

The browser version stores the same data in your browser’s local storage on the device you use, caches the app for offline use, and keeps a small local log of how the interface is used (for example, taps to the first solution) so we can judge the design during testing. That log never leaves the browser. Clearing the site’s data in your browser removes all of it.

App stores and beta distribution

If you install a test build through Apple’s TestFlight or Google Play’s testing tracks, Apple or Google may collect device information, crash reports, and any feedback you choose to send, under their own privacy policies, and may share crash reports and feedback with us.

Information you send us

If you email support, we receive your email address and the message, screenshots, or exported records you attach. Those copies are separate from the records stored in the app. An export may include saved coordinates, so review it before sending it.

When you request a field-test invitation on this website, we store your email address, the signup source, the date, and your IP address. Contact sales@PrecisionRifleworks.us to ask about deleting your invitation request, support correspondence, or feedback we hold.

Children

The app is intended for adults and is not directed to children under 13. We do not knowingly collect personal information from children.

Your choices

• Turn the weather-station feature off, or revoke location permission, to stop sending coordinates for weather lookups.
• Delete saved coordinates with Delete saved location data in Settings.
• Export your data whenever you like; it is yours.
• Delete the app, or clear the web build’s data in your browser, to remove local app records. Delete exported files separately wherever you saved them.
• Contact us about information you sent to support, your field-test invitation request, or beta feedback. Deleting the app does not delete those copies.

Changes to this policy

When the app’s data handling changes, we update this page and the effective date at the top. Material changes are also noted in the release notes of the version that makes them.
