Policy

Last updated: May 10, 2026

TrailStamp is a national parks journal and planning app. It is designed to keep personal memories private by default. TrailStamp does not sell personal data and does not use personal data for third-party advertising or tracking.

Information TrailStamp Uses

Park progress and journal details. TrailStamp stores the parks you mark as visited or planned, visit dates, ratings, notes, best moments, favorites, achievements, and trip plans. This information is used to show your progress, profile, plans, suggested parks, and year recap.

Sign in with Apple profile. If you choose to sign in with Apple, TrailStamp may receive your Apple user identifier and, when Apple provides them, your name and email address. TrailStamp uses this information to show your account profile and sync supported app data with iCloud.

iCloud sync. If you sign in and iCloud is available, TrailStamp syncs your park progress, notes, ratings, favorites, visit details, trip plans, account profile details, and photo memories using your private iCloud database.

Location

TrailStamp may ask for location access to sort nearby parks, show distances, and make nearby park suggestions. Location is used for app functionality. TrailStamp does not sell location data.

Photos and Photo Metadata

If you choose to import photos, TrailStamp stores compressed copies of those photos locally on your device for the photo journal. TrailStamp may read photo metadata such as capture date and GPS location to suggest a visit date or match a photo to a nearby national park.

When iCloud sync is enabled, those compressed TrailStamp photo copies may sync through your private iCloud database so your photo memories can appear on your other Apple devices.

Purchases

TrailStamp may offer an optional one-time purchase to unlock premium passport features. Purchases are processed by Apple through the App Store. TrailStamp does not receive or store your payment card number, bank account information, or other payment credentials.

Network Requests

TrailStamp may make network requests to:

  • National Park Service APIs for park data, official photos, operating hours, fees, and alerts.
  • NOAA/National Weather Service services for weather forecasts.
  • Apple MapKit for maps and map-related features.
  • Apple iCloud and Sign in with Apple services when you use account and sync features.
  • Apple App Store and StoreKit services when you make or restore a purchase.

TrailStamp does not currently use analytics SDKs, advertising SDKs, or third-party tracking SDKs.

How Information Is Used

TrailStamp uses information to save and show your park progress, build your profile, manage trip plans, import and display your personal photo journal, sort parks by distance, sync supported progress, trip plan, profile, and photo memory data through iCloud, process and restore optional App Store purchases, and load official park, alert, weather, and map information.

Data Sharing

TrailStamp does not sell your personal data. TrailStamp does not share your personal data with advertising networks or data brokers.

Some app features necessarily involve Apple services, such as iCloud, Sign in with Apple, and MapKit. TrailStamp also sends requests to NPS and NOAA/National Weather Service services to load public park and weather information.

Data Storage and Deletion

TrailStamp stores app data locally on your device. If you sign in and iCloud sync is available, supported progress, trip plan, profile, and photo memory data is also stored in your private iCloud database.

You can sign out from the TrailStamp Account section. You can also reset local and iCloud data from the same section. Resetting clears TrailStamp progress, trip plan, and photo memory records, signs you out, clears the local profile, and removes local personal photo files stored by TrailStamp on that device.

You can also delete the app from your device to remove local app data, subject to normal iOS and iCloud behavior.

Children

TrailStamp is not intended to collect personal information from children for advertising or tracking. If children use the app, location, photo, account, and iCloud features should be managed by a parent or guardian through Apple device and family settings.

Changes

This policy may be updated as TrailStamp changes. If the app adds new data collection, analytics, payments, sharing, shared photo libraries, or original-quality photo backup features, this policy and App Store privacy answers should be reviewed and updated.
