Woodlands Trail Guide

Privacy Policy

Effective June 29, 2026

Woodlands Trail Guide is an independent iOS app built by Anthony Compofelice. This policy describes what the app collects, how it uses it, and what choices you have.

What we collect

The app collects only the data necessary to do its job, and we deliberately keep the list short.

• Location. When you grant location permission, your device's GPS coordinates are used on-device to show your position on the map, find nearby trailheads, and follow your progress during walking navigation. Your location is never transmitted off your device, never logged, and never associated with any account.
• Advertising identifier (IDFA). The app shows a small banner ad via Google AdMob to help support development. If you allow tracking via Apple's App Tracking Transparency prompt, Google AdMob may access your device's advertising identifier to personalize ads. If you deny tracking, AdMob serves only contextual (non-personalized) ads. AdMob's handling of this data is governed by Google's advertising privacy policy.
• On-device settings. Your favorites, onboarding state, preferred map style, launch counter, and trip log live in iOS UserDefaults — locally on your device only. Uninstalling the app deletes them.

What we do NOT collect

• No accounts, no sign-up, no email address.
• No analytics SDK, no crash reporter, no usage tracking by us.
• No contacts, photos, microphone, or motion data.
• No server we operate stores any data about you.

Third parties

The only third party with access to any data from this app is Google AdMob, which serves the banner ad. AdMob receives standard ad-request metadata (device type, IP, IDFA if you allow tracking). It does not receive your location, your favorites, or anything else from this app.

Where the trail data comes from

Trail geometry, names, parks, bridges, and amenities are sourced from The Woodlands Township GIS's public ArcGIS REST services. This data is bundled with the app and refreshed periodically from a static mirror hosted on GitHub Pages. No personally identifiable information is sent or received during a data refresh — the app simply downloads a static JSON file.

Children

The app is rated 4+ and is not directed at children under 13. It collects no personal information from any user, including children.

Changes to this policy

If the data the app collects ever changes, we'll update this page and bump the effective date above. Material changes will also be noted in the app's release notes.
