Klaviyo and cookie consent on Shopify
Klaviyo (Klaviyo) is one of the most common trackers on Shopify. Here’s what it does, the data it collects, and how to check whether it fires before your visitors consent.
What is Klaviyo?
Klaviyo is an email and SMS marketing platform very popular on Shopify. Its “onsite” tracking script identifies visitors to personalise campaigns.
What data does Klaviyo collect?
Page views, products viewed and an identifier (cookie `__kla_id`) linking browsing to the Klaviyo profile (often to the email).
Why it needs consent
Klaviyo is a marketing/advertising tracker. In Europe, a non-essential tracker like this must only fire AFTER the visitor consents. If it loads or sets its cookie before, the very purpose of cookie banners isn’t being respected.
How it shows up
We detect Klaviyo via these network/cookie signals:
Does Klaviyo fire on YOUR store?
Our free scanner loads your storefront in a clean browser, without touching the cookie banner, and tells you in ~30 seconds which trackers fire before consent — and which app loads them.

The fix is to actually block the tracker until the visitor consents (via your tag manager, theme, or a properly configured banner). We’re building the Shopify compliance assistant that pinpoints the responsible app and blocks trackers before consent — automatically.
