Tågkollen 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.
Tågkollen 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 | 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. |
| 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, logged, or transmitted anywhere other than the single Trafikverket API call needed to answer "what's the next train?" — described in the next section.
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.
Only 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.
There are no analytics, no advertising, no crash-reporting services, and no data brokers of any kind built into this app.
Tågkollen 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.
