We use cookies to ensure that we give you the best experience on our Website. This policy provides detailed information about how and why we use cookies and how you can manage your cookie preferences.

1. Cookies and Other Tracking Technologies

A cookie is a small file of letters and numbers that we store on your browser or the hard drive of your computer if you agree. Cookies contain information that is transferred to your computer’s hard drive.

1.1. Types of Cookies

Cookie types by the duration of use: The Website uses permanent cookies according to the duration of use. Permanent cookies are not deleted when the internet browser is closed and are automatically deleted on a certain date or after a certain period of time.
First-party and third-party cookies: Cookies set by the Website owner (in this case, Ottan) are called “first-party cookies” (i.e, the URL shown in the address bar of the browser (www.ottan.co.uk). Cookies set by other than the Website owner are called “third-party cookies”. Third-party cookies enable third-party features or functionality to be provided on or through the Website (e.g., advertising, interactive content, and analytics). The parties that set the third-party cookies can recognize your computer both when it visits the Website in question and also when it visits certain other websites.

Cookies are not the only way to recognize or track visitors to a Website. We may use other, similar technologies from time to time, like web beacons (sometimes called “tracking pixels” or “clear gifts”). These are the tiny graphics files that contain a unique identifier that enables us to recognize when someone has visited our Website or opened an e-mail including them. This allows us, for example, to monitor the traffic patterns of the users from one page within a Website to another, to deliver or communicate with cookies, to understand, whether you have come to the Website from an online advertisement displayed on a third-party website, to improve site performance, and to measure the success of email marketing campaigns. In many instances, these technologies are reliant on cookies to function properly, and so declining cookies will impair their functioning.

1.2. How We Use Cookies and Tracking Technologies

We use the following cookies:

Essential cookies. These are necessary for the operation of a Website and typically do not require user consent. These cookies ensure that the Website functions correctly and provides services requested by the user.
Advertising cookies. These cookies record your visit to our Website, the pages you have visited and the links you have followed. We will use this information to make our Website and the advertising displayed on it more relevant to your interests. (We may also share this information with third parties for this purpose so that they can serve you with relevant advertising on their websites.)

You can find a list of the cookies we may deploy, including their duration, below.
