RailCheck Sweden is a Garmin Connect IQ watch app that shows live Swedish train departures from Trafikverket. This page explains, plainly, what data the app touches and what it does with it.
RailCheck Sweden is built and published by an independent developer, not a company. There is no backend server operated by the developer — the app running on your watch talks directly to Trafikverket's public API. No data passes through, or is stored on, any server the developer controls.
| Permission | Used for |
|---|---|
| Positioning | Reading your watch's GPS location, to work out which train station is your home, your work, or the one currently nearest you — so the app can show the right departures automatically. |
| Communications | Mainly sending your coordinates or a chosen station code to Trafikverket's open data API, to fetch real departure times — no name, email, or device identifier is ever included. Also used for a small amount of anonymous usage tracking; see "Who else sees anything," below, for exactly what that sends. |
| Background | Waking briefly every 5 minutes to refresh departures, so the glance and watch face data stay current without you having to open the app. |
| ComplicationPublisher | Making the next departure time available to watch faces that support Garmin's Complications feature, entirely on-device. |
None of this is collected or logged anywhere the developer controls — it's sent directly from your watch to the two destinations described in "Who else sees anything," below.
Everything the app remembers is stored locally, on your watch, using Garmin's on-device app storage — never uploaded anywhere:
Uninstalling the app, or clearing its data from Garmin Connect, removes all of it. Nothing survives outside your watch.
Trafikverket (the Swedish Transport Administration), whose public open-data API this app queries to get real departure information. Their API receives geographic coordinates or a station code and an API key identifying the app — never anything that identifies you personally. Trafikverket's own data is published under a CC0 public-domain license; see their site for how they handle API traffic.
The app also sends a small amount of anonymous usage data to Google Analytics (the same GA4 property this website itself uses — see "This website," below): a random identifier generated on your watch and stored only there, when the app is opened (which mode you're using, the app version) and when you switch between the main screens (which screen). This is aggregate "how many people use which feature" counting, not tracking of who you are — no name, email, GPS coordinates, station choice, or device identifier is ever included, and the random identifier isn't linked to anything else Google or the developer holds about you.
There is no advertising, no crash-reporting service, and no data broker of any kind built into this app.
RailCheck Sweden isn't directed at children and doesn't knowingly collect data from them — the app has no concept of a user identity or age at all; it only ever handles a location and a station choice.
If what the app collects or how it's used ever changes, this page will be updated and the date at the top revised accordingly. Since the policy lives at a stable URL, checking back here is enough — there's no separate notification mechanism.
Everything above the previous section describes the watch app, including its own small Google Analytics usage (section 04). This website — the page you're reading now, and the donation page — is a separate thing, and separately uses Google Analytics to see aggregate traffic like page views and rough visitor counts. Both the app and this website report to the same underlying GA4 property, but with independent, unlinked identifiers — visiting this website reveals nothing about whether or how you use the app, and vice versa.
