Why We Use Cookies

Use of cookies on this website

To comply with the Privacy and Electronic Communications Regulations we periodically conduct a Cookie Audit of our website. This Cookie Audit was last updated on 27 May 2012.

Our website uses a number of cookies to store data on our visitor’s computers. For more information about managing cookies, please see http://www.aboutcookies.org/.


In Summary

Our current assessment of the intrusiveness of the cookies used by our website is as follows:

First-party cookies: we use cookies to monitor how visitors find and use our website. We report on this activity in aggregate, and use this information solely for the purposes of monitoring and improving our website.

Third-party cookies: we use a variety of widely-used third-party plugins as marketing tools for our own business and to provide convenience tools for our visitors. In our belief the use of these plugins represents current "best practice". We have no direct control over the content of the cookies they create, the use made of any data collected, or the security of that data. These third parties may collect information about your visit to our website, and they may use this with other data in order to serve advertising which may be more relevant to you.

Some visitors may see this use of data as intrusive to some degree. We believe there is no reason for our website visitors to be particularly concerned about the privacy implications of any of the cookies we use, but we do recognise the importance of making you aware of the purpose and scope of the data stored in the cookies which are created or updated on your computer when you visit our website.

You may choose to delete these cookies from your computer between visits to our website. We recommend that if you have concerns about the privacy implications of the cookies we use, then you should investigate how to do this using the cookie management tools in your web browser.


In Detail

First party Cookies: First party cookies are specific to the host site that created them (in this case, northerntankservices.co.uk). In all cases these first-party cookies do not store any personal or sensitive information, or anything that makes you personally identifiable to us.

Session IDs: Our web server creates an essential session cookie which is essential for your use with our Wordpress website. The cookie contains a session ID which is a mechanism for distinguishing your visit to our website from any other visitors that may be using the website at the same time. For more information you can read technical articles on the Microsoft website about Session IDs. This cookie expires when you leave our website.

Cookie Consent: If you have chosen to consent to our use of cookies, as outlined on this page, then we place a cookie called usecookiestanks on your computer. This stores the word "Yes" and is set to expire 20 years after you first give us your consent.

Analytics: We use Google Analytics, which creates a number of first-party cookies, all prefixed __utm:

__utma: contains a unique and anonymous identifying ID, which allows us to ensure that subsequent visits to our website are recorded as belonging to the same (unique) visitor. This cookie expires after two years.

__utmb: used to establish and continue a unique user session. Each time you request another page from the website the cookie is updated to expire after 30 minutes.

__utmc: works with __utmb to determine when to create a new session for a website visitor. This is a session cookie and expires when you exit the browser.

__utmz: tracks how you found us and is used to calculate traffic and navigation within the website. It is updated with every new page view and expires after 6 months.

You may also sometimes find a __utmv cookie which relates to custom reporting segments, a feature which we occasionally use on Google Analytics.

Full details of the cookies which Google Analytics uses can be found in Cookies & Google Analytics in documentation for Google’s Analytics tracking code. You can also read Google’s Privacy Policy for Google Analytics. We don’t share the data that Google Analytics collects, and we don’t believe that our use of Google Analytics is privacy-intrusive.

We use the data that is collected in the following ways: to report, in aggregate, how our visitors find and use our website; to understand overall visitor behaviour; and to inform how we update and improve our website. To opt out of our use of Google Analytics you may wish to consider using the Google Analytics Opt-out Browser Add-on.

Third-party cookies: In addition to our first-party cookies, you may be served one or more of the following third-party cookies during your visit to our website. Third party cookies are cookies created by an external service when you use a page on our website. These cookies are specific to the third-party’s domain and accordingly the data held in them can be seen and managed by the third party and not by us. We control whether or not we use the third-party service with our website, and how it is integrated and presented on our website. We do not have control over the cookies themselves.

Flash Local Shared Object (LSO) storage: If you want to manage the contents of your Flash Local Shared Objects, please use Adobe’s Website Storage Settings panel. We do use Flash technology on our website and information on the cookies Flash uses and their management can be found here.

Other cookies we may be using: We occasionally trial other services which may create cookies on your computer. If we are currently doing so then these trials will be listed here. No other trials are currently running.
