<summary><strong>Is it legal to use Google Analytics?</strong></summary>

From the decisions made so far by the data protection authorities of the EU member states, a recommendation crystallized for how US tools can be used in a DSGVO-compliant manner. The solution is very simple: Instead of transferring data directly to the USA (or to US servers in the EU), JENTIS interposes its patented twin-server technology. Here, personal data is pseudonymized and only then is the data forwarded to US tools such as Google Analytics.

<summary><strong>What resources are needed to implement JENTIS?</strong></summary>

Based on our experience, you will need a **developer/IT employee** for the initial setup, which includes adding the JavaScript snippet and configuring the A-record.\
This task typically requires **no more than one person-day** of a technician's time.\
After this step, the remaining implementation can usually be handled by **team members with tracking experience** or by your **agency partner.**
