Vasenglück review for Complianz GDPR Cookie Consent

Aug. 24, 2025

We experienced recurring problems with this app. One major issue: the cookie banner went offline for a long time because an update was supposed to be triggered manually. Unfortunately, there was no notification about this – you only see it if you actively open the app. This meant our tracking was not working properly for a long time. Another frustration: technical support is only possible via installing a separate support app. This is very unusual compared to other Shopify apps, where normal backend access is sufficient. The final straw (and the reason we uninstalled the app): without making any changes in our shop, the cookie banner simply disappeared. It had been active in the settings, yet suddenly our Klaviyo newsletter signup forms were no longer visible in the shop. After some digging, we discovered it was caused by the cookie banner app. As a result, Google Ads performance also dropped drastically since no data was being sent. In summary, this app caused us significant business damage, and we cannot recommend it.
