Vehicle Motion Cues reduces motion sickness by drawing gentle dots that move with your
vehicle. Everything it needs happens on your phone. This policy explains exactly what the
app touches — and what it never does.

In short
No personal data is collected. The app has no accounts, no sign-in, and no user profiles.
Nothing leaves your device. Motion, activity, and location signals are processed on the phone in real time and are never uploaded, stored, or shared.
No analytics, ads, or trackers. The app contains no advertising and no third-party tracking SDKs.
What the app processes on your device
To move the dots in sync with the vehicle, the app reads a few live signals from your phone
while the cues are running. These are used only in the moment, on the device, to compute where
the dots should be — then discarded. They are not written to a server or to any file that
leaves your phone.
Motion sensors (accelerometer / gravity) — to detect acceleration, braking, and turns so the dots can respond.
Physical activity — used only to detect when you enter or leave a vehicle, so Automatic mode can start and stop on its own.
Location (optional) — if you grant it, GPS speed and heading improve accuracy and let the cues start when you begin moving. The app requests foreground location only; it never requests background location. Cues work without location.
Information we collect
None. Vehicle Motion Cues does not collect, transmit, sell, or share any
personal or device information. There is no backend server that receives your data. Because
nothing is collected, there is nothing for us to retain, export, or delete on your behalf —
uninstalling the app removes its on-device settings.
Permissions, and why each is used
Display over other apps — draws the motion dots on top of whatever app you are using while you ride.
Notifications — shows the ongoing notice Android requires while the overlay service runs.
Physical activity — detects vehicle entry/exit for Automatic mode.
Foreground service — keeps the sensor and overlay pipeline alive while cues are showing.
Run at startup & wake lock — lets Automatic mode re-arm after a reboot and keeps the cues responsive in the background.
Children
Vehicle Motion Cues is a general-audience accessibility utility. It is not directed at
children and does not knowingly collect information from anyone, including children.
Changes to this policy
