This policy is superseded and is kept only so its original URL keeps working. It describes the earlier device-only version of the app, which had no internet permission. That is no longer how Interstate Tracker works: the current app syncs to a server.
The current, versioned policy is at interstatetracker.com/privacy.
Last updated: 6 August 2026
Interstate Tracker records which parts of the U.S. Interstate Highway System you have driven. Doing that requires your location. This policy describes what the app does with it.
The short version: everything stays on your phone. The app has no permission to access the internet, so it cannot send your data anywhere, and it does not.
What the app accesses#
Location. With your permission, the app reads your device’s GPS location, including while it is in the background, so it can record a drive without you having to keep the app open. Location is used to match your route against interstate geometry that ships inside the app.
Physical activity. With your permission, the app reads Android’s activity recognition signal to detect automatically when you have started or stopped driving. You can decline this and start and stop trips manually instead.
Notifications. While a trip is recording, the app shows an ongoing notification, as Android requires for an app using location in the background.
Where that data goes#
Nowhere. It is stored in the app’s private storage on your device and is never transmitted.
This is not only a policy commitment. The app does not request the Android
INTERNET permission, so the operating system prevents it from making any
network connection at all. There is no account to create, no server to sync
with, and no analytics, advertising, or crash-reporting service in the app.
Because your data never leaves your device, there is nobody to sell it to, and no third party receives it.
Google Play services#
The app uses Google Play services on your device for location and activity recognition. These are Android system components, not part of Interstate Tracker. Any processing Google performs through them is governed by Google’s own privacy policy, at https://policies.google.com/privacy. Interstate Tracker does not send Google, or anyone else, the data it stores.
Data you choose to export#
The app can export your trips and coverage as a file, and can import GPX files you already have. Exporting is always something you initiate. Once you have saved or shared an exported file, it is an ordinary file on your device and outside the app’s control — where it goes next is up to you.
Keeping and deleting your data#
Your data stays on your device until you remove it. You can delete individual trips from within the app. Uninstalling Interstate Tracker deletes everything it stored, permanently; because there is no server copy, this cannot be undone and there is nothing left behind to request the deletion of.
Children#
Interstate Tracker is not directed at children under 13 and does not knowingly collect information from them.
Changes to this policy#
If a future version of the app changes what it does with your data — for example by adding optional accounts or cloud sync — this policy will be updated before that version is released, and the change will be described here.
