How Stump n Grind uses cookies

Both Stump n Grind and third parties make use of cookies when you visit our websites. The following is a description of the types of cookie that are used, why they are used and details of the individual cookies.


Session cookies are used by us to recognise a user throughout a visit. This enables us to remember information that you have entered, for example, the product you have selected during a purchase which can then be used at each stage of processing your purchase. Session cookies are also used to remember you when you log in for the duration of your visit.


Persistent cookies allow us to retain information and settings about a user for more than one session. These cookies stay on a computer or a device until they expire or a user removes them. They enable us to recognise a user when they return to our site, identify their preferences so as to provide a user with a more personalised service and speed up searches a user conducts when visiting the site. They allow us to tailor marketing and servicing messages to users based on what we know users have or haven’t done in previous sessions. We are able to optimise the website for a user’s return to the site knowing whether they have previously bought something or whether they may need support to complete a service transaction.


Cookies enable us to identify which type of advertising results in sales. This means that we are able to tailor our marketing more effectively.

Website analytics:

Website analytics enables us to see how people use our website. This gives us the information to be able to make improvements, to make the site easier to use and based on the areas of the site people find most useful.

Website optimisation:

We test different versions of parts of the site before we finalise changes to ensure that any improvements make the site easier to use for our customers. Cookies help us to track how a user progresses through sections of the website that we are testing.
