  • vehicle-icon-mode: remembers whether vehicle markers use standard icons or directional triangles.
  • map-clustering: remembers whether vehicle clustering is enabled.
  • app-theme: remembers the selected app theme.
  • app-theme-custom-color: remembers a custom theme color, if selected.
  • layer-visibility: remembers which map layers are shown or hidden.
  • follow-location: remembers whether the follow-location control is enabled.
  • tracked-vehicle-id: temporarily remembers the vehicle you chose to follow so the app can offer to resume tracking.

These cookies are set by Boston Train Tracker and are used only to provide the preferences and map behavior described above.

Analytics

Boston Train Tracker uses Rybbit for privacy-friendly analytics. Rybbit does not use these preference cookies, and Boston Train Tracker does not use cookies for analytics.

Analytics are used to understand general site usage and are not used to identify visitors.

How long cookies last

Preference cookies are currently set to expire after approximately one year. If you change a setting, the related cookie may be refreshed for another year.

The tracked-vehicle-id cookie is cleared when you stop tracking a vehicle, decline to resume tracking, or start a conflicting tracking mode.

Managing cookies

You can clear these cookies at any time through your browser settings. Clearing cookies may reset map preferences such as theme, visible layers, clustering, and follow-location behavior.

Because these cookies are used only for app preferences, Boston Train Tracker does not currently provide a separate cookie consent banner.
