# Synthetic Users Opt Out

By default, when a visitor **declines all consent categories**, the **JENTIS Predictor Collector** remains active. In this mode, JENTIS may still collect limited, non-consent-based data to train internal machine-learning models. This data is used to improve **Synthetic Users** and, where possible, to assign visitors to behavioral segments.

For some visitors, this behavior may be undesirable. They may expect that **declining all consents also disables any form of data collection**, including data used exclusively for machine-learning purposes.

To address this requirement, JENTIS provides an explicit **opt-out mechanism**. This opt-out can be triggered programmatically and fully disables the Predictor Collector for the current visitor.

#### Recommended Usage

The most common implementation is to expose this opt-out option on your **Data Privacy** or **Privacy Policy** page. Typically, this is done by:

* Adding a clearly labeled **“Opt-out from data processing”** or **“Disable data collection”** link
* Executing the JENTIS opt-out function when the visitor clicks this link

Once executed, the Predictor Collector will no longer collect data for this visitor, even if no consent has been granted.

#### Implementation

The following function is provided by JENTIS and can be executed, for example, in an `onclick` handler of a link or button:

```
window.jentisApp.optOutSyntheticUsers();
```
