Plain-language summary
The App stores everything on your device. We do not run a server, we do not collect analytics, we do not have user accounts, and we do not share any information with third parties for advertising or tracking. The only personal data the App ever touches is your device's location, and it never leaves your device.
§ 01 Information We Collect
The App accesses the following information only with your permission and only while the App is in use:
- Precise location. Used to display historical markers near you on the map and to sort the "Nearby" list by distance from your current position. Location data is read from iOS, used in real time, and is never stored, logged, or transmitted anywhere.
§ 02 Information Stored on Your Device
The App stores the following on your device using Apple's SwiftData framework. This data lives in your device's private app sandbox and is never sent off the device:
- The bundled Pennsylvania Historical Marker dataset (titles, descriptions, coordinates, counties — published publicly by the Pennsylvania Historical and Museum Commission).
- A flag and timestamp recording which markers you have marked as "visited," if you choose to mark any.
You can erase all of this at any time by deleting the App from your device.
§ 03 Network Activity
The App makes network requests only in one circumstance:
- When you tap "Refresh from data.pa.gov" in the Settings screen, the App downloads the latest marker dataset from
data.pa.gov, a public open-data portal operated by the Commonwealth of Pennsylvania. The request includes only the standard HTTPS metadata required to deliver the response (your device's IP address as seen by data.pa.gov, the User-Agent set by iOS, and the URL of the dataset). This request is governed by data.pa.gov's privacy policy.
No other network activity occurs. The App does not use ads, analytics SDKs, crash reporting services, or third-party trackers.
§ 04 Third-Party Services
None. The App contains no third-party SDKs.
The map view is rendered by Apple's MapKit framework, which is part of iOS and governed by Apple's privacy policy.
§ 05 Your Choices
- Revoke location access at any time in iOS Settings → Privacy & Security → Location Services → PA Historical Markers. The App will continue to function; markers will simply not be sorted by distance.
- Delete all data by removing the App from your device.
§ 06 Children's Privacy
The App is suitable for all ages and does not knowingly collect personal information from anyone, including children under 13.
§ 07 Changes to This Policy
If we materially change this policy we will update the effective date above and, where appropriate, note the change in a future App release.
