Booking Information: When booking vehicle hire services we ask for your name, postal address, telephone number and email address. This helps us to process your booking, to contact you if we have any problems with your request or to send you an electronic confirmation of the booking.


We try to ensure that the personal data we retain about you is stored securely and is as accurate, current and complete as necessary for the purposes we use it for.


We generally retain personal data about our customers for as long as we believe appropriate for the purposes for which it was collected or as otherwise required by applicable law. Our principal electronic database for storing the personal data we collect is secure, local and not virtual. 


As you may be aware, there is no completely secure method of transmitting or storing data. Although their physical characteristics are different, postal mail, telephone calls, text messages, faxes and transmissions over the Internet all present possibilities of loss, misrouting, interception and misuse of the data that is transmitted.

We aim to maintain appropriate physical, procedural and electronic safeguards to protect your personal data, including: Restricting access to personal data to our employees on a “need to know” basis; Enforcing policies and procedures for our employees in their handling of personal data.


You may access and review your personal data and correct factual errors upon request. To protect your privacy and the security of your personal data, we will take steps to verify your identity before granting you access or making corrections to the data we store about you.
