Before you use the ULEZ Checker skill

ULEZ Checker is intended to be used only for certain purposes. By submitting a request to the ULEZ Checker skill, you acknowledge that one or more of the following cases apply:

  • You are either the owner or registered keeper of the vehicle being checked; or

  • The vehicle registration number relates to a vehicle that is being, or is intended to be, marketed or offered for sale; or

  • You have a genuine and legitimate interest in determining whether or not the vehicle is ULEZ compliant; or

  • The vehicle registration number relates to a vehicle that you are involved in providing services to.

How We Collect Your Personal Information

The ULEZ Checker skill does not collect any personal information from you, except the car registration which you are checking is ULEZ compliant. Car registration plates cannot be used to identify you directly as an individual except by the UK Government’s Driver & Vehicle Licensing Agency.

Our skill does not use Account Linking at the present time, although it is our intention to use this functionality in future releases and this policy covers that usage. In the case, when we do use Account Linking, your explicit consent will be sought and required. Our intention is to use any data that we collect from our skill users to:

  1. Improve the functionality of our ULEZ Checker skill by making it more accurate. Our intention is to use the collected data together with our proprietary algorithms, AI and improved Natural Language Processing to provide enhanced and improved auto correction experience for our skill users.

  2. In the case, where a car registration indicates that a car is not ULEZ compliant (that is the vehicle may be subject to charges when it enters an Ultra Low Emission Zone) to make suggestions on replacement vehicle makes and model(s) which would be ULEZ compliant.

The Types of Information We Collect

We only collect the information that's necessary such as your registration plate, to provide the particular service you've requested, and to keep you informed of related content and information that we think may be of interest to you.

Why We Collect Your Personal Information and How We Use It

Generally, we will use your information to provide a service you have requested, to offer you a more personalised experience, so we can understand our customers' needs better.

The information we collect may be disclosed when legally required to do so, at the request of governmental authorities conducting an investigation, and applicable laws or to protect against misuse or unauthorised use of our skill.

The information you provide may be shared with third-party suppliers such as Transport for London to assist us in the use of the data for the purposes described in this policy.

How We Handle Your Information and Other Organisations

We will never share, sell, rent or trade your personal information to any third parties for marketing purposes without your prior consent. We will always ask for your consent to share personal information with anyone else other than Transport for London.

ImproveCX is not responsible for the privacy notices and practices of Transport for London, even if it accessed as a web service using our skill. We recommend that you check the policy of Transport for London on their website and contact its owner or Data Protection Officer if you have any concerns or questions.

Security and Retention

Despite all our precautions, no data transmission over the internet is 100% secure. So, whilst we ensure that we have in place all appropriate security measures to protect your data we cannot guarantee the security of any information which you disclose to us and so wish to draw your attention to the fact that you do so at your own risk.

We'll keep your personal anonymised information for as long as we need it to provide the required services. We may also keep it to comply with our legal obligations, and resolve any disputes.

In all cases, our need to use your personal anonymised information will be reassessed on a regular basis, and information which is no longer required for any purposes will be disposed of.

We reserve the right to provide information to law enforcement agencies or assist where it is necessary for the prevention & detection of crime.
