This policy covers ParkMarker and Springly (the "Apps"), made by Trailmarker Studios ("we", "us"). We built these apps to be simple, offline-friendly tools — and we've tried to keep the data we touch just as simple.
We do not run any analytics or advertising SDKs in either app, and we do not track you across other apps or websites. The only diagnostic information we receive is standard crash reports generated by Apple's built-in crash reporting, if you've opted in to sharing those with app developers in your iOS settings. These reports help us fix bugs and do not include content you've entered in the app.
Both apps can request access to your device's location. This is used entirely on-device to show you parks or springs near you and to support location-based check-ins (e.g. marking a park as visited while you're there). Your location is not sent to us or stored on our servers, and you can deny or revoke location access at any time in your device's Settings without losing core functionality.
Signing in is entirely optional. If you choose to link a Google or Apple account, we receive the account ID and email address that provider gives us, so your ratings and reviews can follow you to a new device. We don't use this for anything else, and we don't share it with anyone.
ParkMarker connects to a database we operate to display park ratings and to let you submit your own ratings and reviews. If you're signed in, these are linked to your account so you can edit or remove them later — but they're never published with your name or email. If you're not signed in, they're tied to a random, anonymous device ID instead. You can also submit feedback or bug reports, which we use only to improve the app.
Cloud Sync is an optional subscription that backs up your favorites, visit history, and notes to a server we operate, so they can be restored if you reinstall the app or switch phones. This backup stays on our servers until you delete your account — canceling the subscription pauses new backups but doesn't delete what's already there. See deleting your account for details.
Purchases (the one-time Unlimited Park Access unlock and the Cloud Sync subscription) are handled entirely through Apple's App Store or Google Play. We never see or store your payment details.
Our apps are not directed at children under 13, and we do not knowingly collect personal information from children.
If this policy changes, we'll update this page and revise the date above. Significant changes will also be noted in the app's release notes where practical.
