Introduction
CleanZone UK (“we”, “our”, or “us”) is committed to protecting your privacy. This Privacy Policy explains how the CleanZone UK mobile application (“the App”) collects, uses, stores, and shares information when you use the App.
By using CleanZone UK, you agree to the collection and use of information in accordance with this Privacy Policy.
Who We Are
CleanZone UK is an independent mobile application owned and operated by ulez.co.uk.
Information We Collect
Vehicle Registration Information
When you enter a vehicle registration number (number plate), the App uses it to retrieve vehicle information and determine compliance with:
- Ultra Low Emission Zone
- Clean Air Zones
- Congestion Charge (where applicable)
If you choose to save a vehicle, the registration number and associated compliance information are stored locally on your device to improve your experience.
Location Information
The App may request access to your device’s precise or approximate location.
Location is used only for features that require it, including:
- Detecting whether your current location is inside or near a ULEZ, Clean Air Zone (CAZ), or the Congestion Charge Zone.
- Supporting the Use Current Location feature when checking destinations or planning trips.
- Providing optional Zone Entry Alerts when enabled by you.
Location permission is optional.
You can continue using the App without granting location permission, although location-based features may not function.
CleanZone UK does not continuously track your location in the background for advertising or profiling purposes.
We do not sell your location information.
You may revoke location permission at any time through your device settings.
Saved Vehicles
If you choose to save vehicles within the App, vehicle information is stored locally on your device so that you can quickly access compliance results without repeatedly entering registration numbers.
Reminder Information
If you enable reminders, the App may store reminder information such as:
- MOT expiry reminders
- Vehicle tax reminders
- Custom reminder preferences
Reminder information is stored only to provide these features.
Usage Information
We may automatically collect limited technical information such as:
- Device model
