Sleeper Train Privacy Policy

Last updated: 11 September 2026

Sleeper Train does not collect, store, transmit, or share any personal data.

What the app does

Sleeper Train plays a designed overnight train journey, mixed live on your iPhone from audio files built into the app. That is the whole of it. It asks for no permissions at all: no microphone, no location, no notifications, no contacts, no photos, no health data, no motion.

The arrival time it suggests comes from a sunrise worked out from the date and your device’s time zone. It does not use Core Location, so the app never knows where you are.

What is kept

One thing, on your phone: whether you have read the first-run sheet, so that it appears once and then stops. The time you ask to arrive lives only while the app is running and is not written anywhere.

Network

Sleeper Train makes no network connections. It has no analytics, no advertising, no accounts, no in-app purchases, and no third-party services. Every sound is inside the app, so nothing is fetched to make it work and nothing is reported back.
