Data and permissions
- No sign-up, and nothing is sent to the developer's servers.
- Location is used only to find nearby stops. Only an approximate position (rounded to 100 m–2 km) goes to Korea's public bus-information APIs, and stop search works without location access.
- Notification permission is requested only when you turn on an arrival alert.
- Favourite and recent stops, and saved stop and route information, stay on this device.
- Arrival data comes from Korea's public transit data (MOLIT TAGO, Seoul, Gyeonggi) and may differ from actual times.
