Introvert Maps — Privacy Policy

Effective date: 5 July 2026

Introvert Maps is an offline-first hiking and biking map for iPhone and Apple Watch. It is built to work without an account and without tracking you. This policy explains, plainly and completely, what the app does and does not do with your data.

The short version

• There are no user accounts and no sign-in. We do not ask for your name, email, or any profile.
• The app is offline-first: you download maps, routing data, and train timetables while you have a connection, then use them (and on-device search) without a signal. Weather forecasts and live train-delay updates refresh over the internet when it is available and are cached, so the last copy still shows when you go offline.
• We use no third-party advertising or analytics SDKs, and we do not track you across apps or websites.
• The only information that ever leaves your device to us is an optional diagnostics report that is turned OFF by default — nothing is sent unless you switch it on yourself.

Data downloaded to your device

To work offline, the app downloads map regions, routing data, and train timetables while you have a connection; once downloaded they are stored on your device and used without a signal. The map files are served from our content-delivery domain (cdn.introvertmaps.com) and the app fetches a small index and a few live features from our server (maps.introvertmaps.com). (On first launch the app may also fetch a coarse overview of your current region so a map appears.) Downloading a file necessarily involves your device's IP address, which is visible to the hosting server as part of any internet request; we do not use it to build a profile of you, and there are no accounts to attach it to.

Two features refresh over the internet when it is available and cache their results on your device so the last copy still shows offline: live train-delay updates (fetched from our server) and weather forecasts (described below).

Location

With your permission, the app uses your location to show your position on the map, to keep you oriented while hiking, and to plan routes. Route planning runs entirely on your device using downloaded routing data — your location and routes are not sent to us for routing. Aside from the weather forecast described below (where a coordinate is sent to fetch a local forecast), your location is not shared with anyone, and it is never shared with advertisers or used to track you.

Weather

When you open the weather view, the app fetches a local forecast for the area you are looking at. It normally requests this through our own server (maps.introvertmaps.com), which relays the free Open-Meteo weather service. If our server cannot be reached, the app queries Open-Meteo directly as a fallback — in that case the approximate (rounded) coordinates are sent to Open-Meteo so it can return the forecast for that area. No account, name, or identifier is attached to the request. The forecast is cached on your device so it can be shown again while you are offline.

Optional diagnostics (off by default)

The app has an optional Diagnostics setting that is turned off by default. It stays off, and nothing is sent, unless you explicitly enable it in the app's settings. It exists so that, if you run into a problem, you can help the developer diagnose it.

When — and only when — you turn Diagnostics on, the app sends its application log to the developer's server (maps.introvertmaps.com/ingest). This log:

• can include GPS coordinates (they appear in the diagnostic log lines the app records while running);
• includes a random per-install identifier generated on your device, used only to group log lines from the same installation — it is not tied to your identity and is not an advertising identifier;
• includes basic technical details such as app version and OS version, and crash and hang summaries (collected via Apple's MetricKit) that ride the same channel — these too are sent only while Diagnostics is on.

When you enable Diagnostics, only log lines recorded after you opt in are sent; earlier history is not retro-shipped. Turning Diagnostics back off stops all sending immediately. This data is used solely to diagnose and fix problems in the app. It is not sold, and it is not shared with advertisers or analytics providers.

Apple Health (Apple Watch)

If you choose to record a hike as a workout on Apple Watch, the app uses HealthKit to save that workout (and to keep GPS active during the hike). This data is stored in Apple's Health app on your device under your control. It is not sent to us and is not used for advertising.

Camera and photos

The camera and photo-library permissions are used only for the app's in-app night-photography feature. Photos you capture are saved to your own photo library. They are not uploaded to us and are not shared with any third party.

Sharing maps with a nearby device

The app can share already-downloaded map regions directly with another nearby device over a local peer-to-peer connection (using Apple's MultipeerConnectivity / local network). This is a device-to-device transfer for hikers without signal — the map data travels directly between the two devices and does not pass through our servers.

Children

The app is a general-purpose maps utility and is not directed at children. It does not knowingly collect personal information from children.

Map data attribution

Map data is derived from OpenStreetMap, © OpenStreetMap contributors, available under the Open Database License (ODbL).
