> **Note:** This guide focuses **only** on the technical aspects of integration. It is **not** a legal assessment or compliance consultation.

### Recap: What Is Essential Mode?

**Essential Mode** allows a data stream to operate in a **fallback configuration**.\
It can apply different schemas to individual property values, for example:

* **Anonymization** – Removing identifiable information
* **Pseudonymization** – Replacing identifiers with non-identifying placeholders

### Why Use Essential Mode?

If certain data cannot be processed without explicit user consent, Essential Mode allows you to:

* **Continue tracking with reduced detail** when consent is denied
* Ensure that **only data not requiring the same legal justification** (e.g., anonymized data) is sent to connected tools
* Maintain a **functional tracking setup** while respecting user privacy choices

Example:\
If a user denies consent, you could still send anonymized pageview data to an analytics tool, which is **not subject to GDPR restrictions** in the same way as personally identifiable information.
