Leaveby is built to be private by default. There is no account, no sign-in, and no tracking. The short version: we don’t collect your data, and your location never leaves your device.
Leaveby works fully anonymously. You never create an account or sign in, and the app does not ask for your name, email, contacts, or any personal identifier.
Leaveby asks for your location only while you’re using the app (“When In Use”). It uses your location on your device to find nearby stops and stations and to estimate your walking time so it can tell you when to leave.
Your location stays on your device. When the app looks up live departures, it identifies stops by their public transit ID — your coordinates are not sent to our servers or to anyone else. You can decline or revoke location access at any time in iOS Settings; the app still works, you’ll just pick your starting point manually.
Nothing. Leaveby has no analytics, no advertising, no tracking SDKs, and no third-party trackers. We do not build a profile of you, and we have no way to identify you.
Real-time arrival data comes from the Metropolitan Transportation Authority’s public GTFS and GTFS-Realtime feeds. To fetch them, the app sends the transit stop ID you’re looking at to a lightweight proxy service (hosted on Supabase) that relays the request to the public feeds. These requests contain the stop ID only — no personal information, no account, and no precise location. Leaveby is not affiliated with or endorsed by the MTA.
Your saved places, starting points, and preferences are stored on your device (and shared with the Leaveby widgets and Apple Watch app through a private, on-device app group). This information stays on your devices and is not uploaded to us.
Leaveby is a general-audience app and does not knowingly collect information from anyone, including children.
If this policy changes, we’ll update this page and the “last updated” date above.
