No Google Tag Manager before consent? The Hanover ruling under legal review

This webinar explores the legal risks of using Google Tag Manager before consent, explains the implications of the Hanover ruling, and offers practical compliance strategies and insights into future EU privacy regulations.

The Administrative Court of Hanover recently ruled that using Google Tag Manager may already pose data protection issues as soon as the container loads, even before any tracking tool is activated. Many companies treat GTM as a neutral container and load it before the cookie banner, but this common practice is now under scrutiny. What does this mean for companies using GTM? Is there even anything to do?

In this webinar, you’ll learn:

  • The legal implications of the ruling: Is GTM truly “technically necessary”? What are the risks of loading it before consent, and what penalties could follow?
  • Your options: Practical solutions ranging from technical adjustments to alternative setups.
  • Bonus – ePrivacy outlook: How will EU legislation evolve, and could cookie banners soon become obsolete?

Hands-on rather than theoretical: Tilman Herbrich from Spirit Legal, one of the leading privacy lawyers in the DACH region, and tracking expert Christian Kletzander will share concrete recommendations for your setup. Bring your questions – we look forward to the discussion!
