What MetroDex is

MetroDex collects the New York City subway stations you’ve run or walked past, using routes you import from Strava or from GPX files. It’s available on the web and as an iPhone app.

Data stored on your device

Everything MetroDex knows about you is stored on your own device, in your browser’s storage on the web or in the app on iPhone:

• The routes you import: the GPS path, date, name and distance of each run, walk or hike.
• The stations, lines and badges you’ve collected, which are worked out from those routes on your device.
• Your settings, such as miles or kilometers and dark mode.
• If you connect Strava, the access keys Strava issues so MetroDex can import your activities.

This data is never uploaded to MetroDex. We can’t see your routes, and nobody else can either unless you choose to share something, such as a badge or your subway personality.

Strava

If you connect Strava, MetroDex asks for permission to read your activities, including private ones, so that your whole history counts. It reads your runs, walks and hikes that have a GPS route, and only uses them to collect stations for you. Your Strava data is shown only to you.

Connecting goes through a small MetroDex server, because Strava requires a secret key that can’t be kept inside the app. That server passes the one-time login code and your access keys between your device and Strava. It doesn’t store them and never receives your activities or routes, which your device downloads directly from Strava.

MetroDex isn’t made or endorsed by Strava. Strava’s own handling of your data is covered by Strava’s privacy policy.

GPX files

GPX files you import are read on your device. They’re never uploaded.

Server logs

Like any website, the MetroDex server and its host, Render, keep standard request logs, such as IP addresses, pages requested and error messages, for running and securing the service. They aren’t used to identify or track you.

Your choices

• Remove a route: open it under Recent routes on Home and tap Remove route. Stations only that route collected are removed too.
• Disconnect Strava: in Settings, tap Disconnect Strava. MetroDex deletes its Strava keys from your device and revokes its access on Strava’s side, so it can no longer read your activities. You can also remove MetroDex at strava.com/settings/apps.
• Delete all your routes: in Settings, tap Delete all routes. Because MetroDex keeps no copy, they’re gone for good, along with the stations and badges they collected.
• Delete everything: delete the app on iPhone, or clear this site’s data in your browser. This also removes your settings and Strava keys.

Children

MetroDex isn’t directed at children under 13 and doesn’t knowingly collect their information.
