What Are Web Cookies?

Cookies are small pieces of data stored on your computer by the web browser you’re using. They’re not very sophisticated at all. In fact, they’re just text files and not very interesting to look at. Here’s an example:

Cookies Screenshot

When you visit a website that uses cookies for the first time, the browser downloads the cookie (or text file) to your computer. So your browser ‘knows’ you’ve visited. When you visit that same site again, your browser checks to see if it has a cookie from that site, if it does, it sends that info back to the site. The site then ’knows’ that you’ve visited before. That’s why sometimes you’ll get a ‘Welcome back’ message. 

Why Use Web Cookies?

Most websites use cookies because they help to improve your online experience. That’s because website developers and writers can create better content for you if they remember you’ve been before. They can do things like not ask for your info again (annoying), remember what’s in your shopping bag (#grateful) and display things as you like them. 

Cookies and the Law

EU and UK legislation state that a website must let you know when it uses cookies. That’s why you get those pop-ups that ask you to accept a website’s cookies when you first visit it. 

So without further ado, here’s our cookie policy:

How Picnic Uses Cookies

The way we use cookies is pretty simple.

  1. Necessary website cookies
    We use a unique XSRF Token cookie as a security measure to protect you against malicious activities such as cross-site scripting. This token is used to validate your user session each time you submit a form or perform an action, which requires a security check.

  2. Google Analytics & PostHog
    These cookies help us analyse our website's performance. They count how many people visit the site and how they use it. This helps us improve the way the website works. For example, we can make information easier to find and read.

  3. Facebook marketing pixel
    Advertising, recommendations, insights and measurement
    We use a Facebook marketing cookie to help us show ads and to make recommendations for our website visitors who may be interested in the products, services or causes we promote. We also use this cookie to help us measure the performance of ad campaigns on Facebook.

Third-Party Cookies

We use Trustpilot widgets to display reviews across our website, which means we are required to add Trustpilot third-party scripts to our website. Trustpilot collects data and stores cookies for its own purposes - you can read more about it here.

Turning Cookies Off

If you don’t want your cookies on, you can disable them by adjusting the settings in your browser.
