# Manage anonymous data collection

Akamas collects anonymized usage information on running optimizations, and you can decide at any moment whether to opt-out.

External tracking is managed through the following environment variables:

* **AKAMAS\_TRACKER\_URL**: the target URL for all tracking info.
* **AKAMAS\_TRACKING\_OPT\_OUT**: when set to 1, disables anonymous data collection.

Tracking for a running instance can be disabled by executing this simple command in the folder where the Akamas compose file is located:

```
AKAMAS_TRACKING_OPT_OUT=1 docker-compose up -d
```

As usual with environment variables, it is strongly suggested to export the desired value to your \~/.bashrc file to ensure persistence.

```bash
echo "export AKAMAS_TRACKING_OPT_OUT=1" >> ~/.bashrc
source ~/.bashrc
```
