Cookie Policy
The cookies and similar technologies this site uses, and why.
We use cookies and browser storage that the site needs to work or to keep it secure. These are always on. We also use analytics and marketing cookies, but only if you agree to them in the cookie banner. You can say no, and the shop works exactly the same. You can change your choice at any time with “Cookie settings” at the bottom of every page.
If you visit from the United States, analytics and advertising cookies are on by default. You can opt out at any time with “Your Privacy Choices” or “Cookie settings” at the bottom of every page. We honour the Global Privacy Control signal from your browser as an opt-out of the sale or sharing of your data for targeted ads. Visitors outside the United States are asked first.
On grizzstudio.co.uk we also count, without any cookie or browser storage, how many visits arrive from each kind of source (for example search, social media or one of our adverts) and how many product views, add-to-bags, checkouts and orders there are each day. The page sends only the step and the kind of source, with no ID, so the totals cannot be linked to you. If you choose “Reject all” or switch Analytics off, you are not counted.

Analytics and marketing cookies (only with your consent)
We use Google Tag Manager to load Google Analytics 4 and Google Ads on this site. Nothing from Google is allowed to store or read identifiers on your device until you choose Accept all, or switch on Analytics or Marketing in Customise. Until then Google only receives a basic signal that you have not agreed. If you choose Reject all, no analytics or advertising cookies are set.
Analytics lets us see which pages and pieces people look at, how people move through the shop and which orders are completed, so we can improve it. Marketing lets us measure our adverts and show Grizz Studio® to people who have visited the shop. If you agree to Marketing, a scrambled (hashed) version of your email address may be sent to Google when you order, so that an advert can be matched to a sale. We never send your email address in readable form.
With Marketing switched on we also use the Meta Pixel (Facebook and Instagram adverts) and Microsoft Advertising (Bing adverts, with Microsoft Clarity) in the same way. Our server also tells Meta about checkout steps and orders (Meta's Conversions API), only if you agreed to Marketing. If you came from one of our adverts and agree to Marketing during your visit, the pieces you viewed or added to your bag earlier in that visit are passed to Meta at that moment; until you agree they stay only in the open page, and if you say no they are discarded.
