Privacy Policy

Your privacy matters to us. This Privacy Policy explains how TrainKeeper handles information when you use the app.

1. Overview

TrainKeeper is designed to store your core train-logging data on your device. Some optional features, such as friend sharing and membership purchases, use Apple services to function.

2. Information We Collect

Data you enter in the app

When you use TrainKeeper, you may create or save:

• train sightings

• photos

• UIC numbers and train numbers

• locations and map coordinates

• routes

• notes

• favorites

• manufacturer, company, and vehicle details

This information is stored locally on your device unless you choose to share it with friends.

Data used for friend sharing

If you enable friend sharing, TrainKeeper may store and sync sharing data through Apple’s CloudKit/iCloud services. This can include:

• your display name

• your profile image

• your sharing settings

• your private sharing token or code

• shared sighting data you choose to publish

Depending on your sharing choices, shared sighting data may also include:

• photo

• location or map coordinates

• route

• notes

• train number

• company

• manufacturer

• country

Data used for membership

If you purchase TrainKeeper Plus, the App Store and StoreKit handle the purchase process. TrainKeeper receives transaction and entitlement information so it can unlock membership features, but it does not receive your payment card details.

Data used for location features

If you allow location access, TrainKeeper uses it to:

• attach coordinates to a sighting

• show sightings on maps

• support nearby location and reverse-geocoding features

If you deny location access, the app still works without location-based features.

Data used for photos and camera

TrainKeeper may request access to:

• your camera, to scan UIC numbers

• your photo library, to select photos for sightings and sharing

If you deny either permission, the app still functions with reduced features.

3. How We Use Information

We use the information above to:

• save and organize your sightings

• show photos, maps, routes, and analytics

• power friend sharing when you choose to use it

• process membership access

• improve the app’s core features

We do not sell your personal information.

4. Where Data Is Stored

• Local sightings and settings are stored on your device.

• Friend sharing data is stored in your iCloud/CloudKit account when sharing is enabled.

• Membership status is stored locally to remember whether the active subscription is unlocked.

5. Third-Party Services

TrainKeeper uses Apple services to provide certain features:

• CloudKit/iCloud for friend sharing

• StoreKit for memberships and subscriptions

• Apple Maps / MapKit and Core Location for map display and location features

• Photos and Camera frameworks for image selection and scanning

These services are operated by Apple and are subject to Apple’s own privacy policies and terms.

6. Sharing and Disclosure

TrainKeeper does not share your local sighting library with other people unless you explicitly enable friend sharing.

If friend sharing is enabled:

• only people who have your current private link or code can access the shared feed

• you can stop sharing at any time

• stopping sharing invalidates the current link and code

7. Retention and Control

You control your data.

• Your local sightings remain on your device until you delete them or remove the app.

• You can stop friend sharing whenever you want.

• You can remove your profile image and sharing settings in the app.

• Membership access is tied to your App Store subscription status.

8. Children’s Privacy

TrainKeeper is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13.

9. International Users

If you use TrainKeeper outside of your home country, your data may be processed and stored on Apple-managed services in other regions as needed to provide CloudKit, iCloud, or StoreKit functionality.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the effective date and make the updated version available.
