Privacy Policy

Last updated June 11, 2026

The short version

Trailmark ADV has no accounts, no analytics, no tracking, and no server of ours. Your waypoints, tracks, trips, photos, and settings are stored only on your device. We cannot see them, and we do not want to.

What the app stores

Everything you create — waypoints, recorded tracks, planned routes, trips, photos, and preferences — is stored locally on your device. It leaves your device only when you explicitly export or share it, and then it goes only where you send it.

Location

The app uses your device's GPS to show your position, record tracks, and create waypoints. Location data is processed and stored on the device. It is never transmitted to us — we operate no servers that could receive it.

Network requests the app makes

To draw maps and provide optional features, the app talks directly to public services: map tiles from USGS, USFS, BLM, and AWS Terrain; Apple Maps for place search; the U.S. National Weather Service for forecasts; and USGS for elevation. (Route snapping currently uses the public OSRM routing service.) These requests carry only the coordinates needed to answer them (for example, the area of map you're viewing) and are governed by those services' own policies. No identifiers, accounts, or advertising IDs are attached — the app has none.

What we collect

Nothing. There is no sign-up, no email list, no crash reporter, and no analytics SDK.

Children

Trailmark ADV does not collect personal information from anyone, including children.

Changes

If this policy ever changes, the updated version will be posted on this page.
