# Manage anonymous data collection

Akamas might collect anonymized usage information on running optimizations. Collection and tracking are disabled by default and can be manually enabled.

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.

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