Hello @mababu,

Welcome to the Klaviyo Community! 

Although we don’t have a list of what our Klaviyo Cookies will track, I think taking a look at our Understanding cookies in Klaviyo Help Center article could help. I believe an important thing to keep in mind is that Klaviyo uses customer-first data is data that’s sourced directly from your customers. This means that visitors to your site aren’t automatically cookied, but rather need to consent prior to being tracked. 

Cookies can also be disabled or blocked through consent management tools such as OneTrust other domain-level blocking tools. You can also maintain Klaviyo JavaScript but remove a cookie by toggling Klaviyo tracking on and off by creating a new cookie, __kla_off, and running document.cookie = "__kla_off=true".

Our Community Champion, @mat.bingham also wrote a great post surrounding the importance of data privacy which I’ve included below:

I hope this helps!

Hello dear Klaviyo Community,

For data protection reasons, we would like to deactivate the setting of cookies in our Shopify store.

I have two questions about this:

1. If I perform the above steps (creating a new cookie, __kla_off, and running document.cookie = ‘__kla_off=true’) for testing purposes in our Shopify development theme, does this only affect the development theme or also the live shop?

2. How can i undo the deactivation of the cookies if any unwanted effects occur?
Would creating a new cookie, __kla_on, and running document.cookie = ‘__kla_on=true’ be the right steps here?

Many thanks for any support 
Stephan
