Privacy Policy

Last updated: September 22, 2026

This policy covers the Subway Pulse website at nycsubway.info and the Subway Pulse apps for iOS and Android. Where the platforms differ, the platform is called out explicitly.

The Short Version

There is no account and no login. We do not know who you are. Your settings live on your device, your location never leaves it, and the only thing we collect is anonymous, aggregate usage data that you can turn off in the app.

What Stays On Your Device

Your pinned stations, your selected route, and your preferences are stored locally — in localStorage on the web, and in app storage on iOS and Android. They are never transmitted to our servers, and clearing your browser data or deleting the app removes them.

Location

The website and the apps can use your location to find stations near you (and, in the apps, to show your position on the line diagram). Location access is always optional — you enable it, and everything else works without it.

Your coordinates are never sent to our servers or to any third party. Nearby stations are calculated entirely on your device, by comparing your position against a station coordinate list bundled with the app or website. On the web your coordinates stay in the browser and are never stored; in the apps your most recent location is cached on-device so the home screen widget can show nearby stations, and it stays within the app’s own storage.

You can revoke location access at any time — in your browser’s site settings on the web, or your device’s Settings in the apps.

Analytics

We use Plausible Analytics to understand which screens and features get used. Plausible is a privacy-focused, EU-hosted analytics service that:

sets no cookies and uses no advertising identifier;
creates no persistent profile — visitors are counted by a hash of IP address and device type that is discarded and re-salted every day;
does not follow you across other websites or apps;
never receives your location, your pinned stations, or any personal information.

The apps report screen views and a small number of feature events (for example, that an “All Lines” view was opened, or that a route was selected). You can turn this off with the “Share anonymous usage data” switch under Privacy in the app’s Help screen; it takes effect immediately. Website and app statistics are kept as separate properties.

Feedback

If you submit feedback, we receive the message you write and, optionally, your email address. Diagnostic information — device model, OS version, screen size, your current route, and the number of stations you have pinned — is included only if you explicitly switch it on, and never includes your location. Feedback is processed by Formspree, Inc.; see their privacy policy.

Advertising

We do not serve third-party ads on the website or in the apps, and we do not use any advertising identifier.

Cookies

We set no cookies. Our analytics provider, Plausible, is cookieless by design.

Third-Party Services

MTA GTFS-Realtime — train position data. Requests go from our servers to the MTA; no user data is sent.
Plausible Analytics — anonymous usage statistics (web and app).
Formspree — feedback form processing.
AWS Lightsail — hosting.

Data Retention

We store no user data on our servers. Plausible retains only aggregate statistics with no individual records. Feedback submissions are retained by Formspree under their retention policy.

Children

Neither the website nor the app is directed at children under 13, and we do not knowingly collect information from them.

Changes

If this policy changes materially, the date at the top will be updated and the revised policy posted here.
