Strictly necessary Always on
Needed for the site to work: your basket, checkout, signing in to your account, security and remembering your cookie choices. The site can't work properly without them.
Our cookie policy.
How StemUp uses cookies on stemup.co.uk, and how you can control them.
Last updated 1 October 2026
What cookies are
Cookies are small text files that a website saves on your device. They let the site remember things, like what's in your basket or whether you've already answered the cookie banner. Similar technologies, such as pixels and local storage, work in much the same way, so we cover them here too.
This website is run by STEM UP LIMITED ("StemUp", "we", "us"). Our store is hosted on Shopify.
The cookies we use
We group cookies into four types. Only strictly necessary cookies are used without asking you first. The rest are only set if you agree to them in our cookie banner.
Preferences Optional
Remember choices you've made, such as your country and currency, so you don't have to set them every visit.
Analytics Optional
Help us understand how people use the site, such as which pages are popular and where people get stuck, so we can improve it.
Marketing Optional
Used to show you relevant StemUp adverts on other sites and social media, and to measure whether those adverts work.
Shopify cookies
Shopify sets cookies to run the store, including the basket, checkout and customer accounts. Some common examples:
| Cookie | What it does | Type |
|---|---|---|
cart | Keeps track of what's in your basket | Strictly necessary |
secure_customer_sig | Keeps you signed in to your account | Strictly necessary |
_tracking_consent | Remembers your cookie choices | Strictly necessary |
localization | Remembers your country and currency | Preferences |
_shopify_y | Shopify's store analytics | Analytics |
Shopify explains its cookies in full in its cookie policy.
Other providers
With your consent, these providers may also set cookies when you use our site:
| Provider | What it's for | Type |
|---|---|---|
| Shopify | Store analytics, such as which pages are visited | Analytics |
| Meta (Facebook and Instagram) | Measuring and personalising our adverts | Marketing |
These providers use the information under their own privacy policies.
Changing your choices
You can change or withdraw your consent at any time. Your new choices apply from then on.
You can also block or delete cookies in your browser settings. Blocking strictly necessary cookies may stop parts of the site, such as checkout, from working. Your browser's help pages explain how: Chrome, Safari, Firefox, Edge.
How long cookies last
Session cookies are deleted when you close your browser. Persistent cookies stay on your device for a set time, from a few minutes up to around two years, or until you delete them.
Changes to this policy
We'll update this page if the cookies we use change. The date at the top shows when it was last updated.
