Cookies Policy

To enhance your experience on our site, many of our web pages use "cookies".

What are ‘cookies’?

Cookies are small pieces of information, which online services provide when users visit them. Software on the user's device (for example a web browser) can store cookies and send them back to the website next time they visit.

How are cookies used?

Cookies are a specific technology that store information between website visits. They are used in numerous ways, such as:

  • Remembering what’s in a shopping basket when shopping for goods online;

  • Supporting users to log in to a website;

  • Analysing traffic to a website; or

  • Tracking users' browsing behaviour.

Cookies are widely used in order to make websites work, or work more efficiently.

What cookies do we use?

We use cookies on dwell.co.uk to help us give you the best experience on our website. By continuing to use our website you’re giving us consent to use cookies.

We may use "session", "persistent", "first party" and "third party" cookies on dwell.co.uk.

What are ‘session’ and ‘persistent’ cookies?

Cookies that expire at the end of a browser session (normally when a user exits their browser) are called ‘session cookies’. Cookies that can be stored for longer are called ‘persistent cookies’.

Session cookies allow websites to recognise and link the actions of a user during a browsing session. They may be used for a variety of purposes such as remembering what a user has put in their shopping basket as they browse around a site.

Persistent cookies are stored on a user’s device in-between sessions. They can allow the preferences or actions of the user across a site (or across different websites) to be remembered. A user can delete previously set persistent cookies manually or configure the browser settings to delete cookies at a set interval.

What are ‘first-party’ and ‘third-party’ cookies?

Whether a cookie is ‘first’ or ‘third’ party refers to the website or domain placing the cookie.

First-party cookies are set directly by the website the user is visiting, ie the URL displayed in the browser's address bar.

Third-party cookies are set by a domain other than the one the user is visiting. This typically occurs when the website incorporates elements from other sites, such as images, social media plugins or advertising. When the browser or other software fetches these elements from the other sites, they can set cookies as well. You should check the third party’s website for more information about how they use cookies.
