This policy describes how the Missoula Ice Age Floods app (“the App”) for iPhone and iPad handles your information.
No account, no collection by us
The App does not require an account. The App does not collect, transmit, or store any personal information on servers we operate. All in-app preferences (units, playback speed, bookmarks, intro state) are stored locally on your device via iOS UserDefaults and never leave the device.
Third-party SDK: Mapbox
The App uses the Mapbox Maps SDK to render its map. Mapbox collects anonymous usage and diagnostic telemetry from apps that embed its SDK, including device identifiers (such as the iOS IDFV), coarse location derived from IP, and performance and crash diagnostics. Mapbox does not link this telemetry to your identity and does not use it for cross-app tracking. Mapbox’s privacy policy is at https://www.mapbox.com/legal/privacy.
Location
Location is optional. The App asks for your location (“When In Use” only) when you tap the Map’s “You Are Here” button, open the AR view, use the Shoreline Scanner, or tap “Check in on site” or “Near Me” in Floodwater Passport. It never asks at launch and never in the background. The position is used on your device for that one answer and is not stored, logged, or sent to us. The nearest town name is looked up through Apple Maps. If you decline, the rest of the App works normally.
Floodwater Passport saves, on your device only, the destination and the calendar day of each visit you log or check in to, plus your saved sites and earned seals. It saves no coordinates, accuracy, distance, route, or time of day. This progress leaves your device only inside an ordinary device or iCloud backup that you control.
Camera, compass, and photos (Shoreline Scanner and AR)
The AR lake view and the Shoreline Scanner use the camera so they can show the live view of your surroundings behind the lake and shoreline lines. Camera images are used on your device to draw that view. They are not stored and are not sent to us or to anyone else. The Shoreline Scanner also uses your location and your device’s compass heading to line the modeled shorelines up with the landscape. These readings are used only on your device, only while the scanner is open, and are not stored, logged, or sent anywhere. The scanner works without an internet connection.
The App saves a photo only when you tap Save. It asks only for permission to add photos to your library; it cannot read, list, or change the photos you already have. A saved Shoreline Scanner photo is written without location or compass data. If you choose to share a photo, it goes where you send it.
Children
The App is rated 4+ and contains no behavioral advertising, in-app purchases, or user-generated content. It is suitable for general audiences. The App does not knowingly collect any information from anyone, including children under 13.
