My Caltrain — Privacy Policy
Effective October 18, 2026
Summary
My Caltrain collects no personal data. There are no accounts, no analytics, no ads, and no tracking. The app does not use your location.
What stays on your device
Your commutes (stations, days, colors, return time), appearance and app icon choice, and your optional 511.org key are stored only on your iPhone. Your commutes are shared with the app's Home Screen widget on the same device. Deleting the app deletes all of it.
Network requests
- 511.org. To get live train times and service alerts, the app asks 511.org for all Caltrain predictions. The request contains an API key (the app's shared key, or yours if you added one) and nothing about you or your stations. 511.org sees your IP address, as any website would. See 511.org's privacy policy.
- Apple Weather. To show weather for your commute, the app sends Apple the map coordinates of your two commute stations, never your own location. See Apple's privacy policy.
Tesoro Industries runs no servers for this app and never receives any of this information.
Children
The app collects no data from anyone, including children.
Changes
If this policy changes, the new version will be posted here with a new effective date.
