# Monitor Language Growth with Data Logging

When data logging is turned on, the device collects language usage data for a person. Data logging helps you track the progress an individual is making with language development. This process allows you to monitor, measure and maximize the person's use of the device.

## Turning Data Logging On/Off

Data Logging allows your device to collect data on what was said and when. Go to **Menu** > **Toolbox** > **Vocabulary** > **Data Logging** to open the Data Logging window.

![The Data Logging window features a on/off toggle to turn data logging on or off, a button to select a folder for exporting a data log, and a button for clearing logged data from the device](https://cdn.document360.io/7e1d5036-9a43-443d-8ea7-a17280ea302d/Images/Documentation/language-development---data-logging-image-iswlson3.png?sv=2026-02-06&spr=https&st=2026-11-07T08%3A42%3A56Z&se=2026-11-07T09%3A42%3A56Z&sr=c&sp=r&sig=sOtFhbOhgYzPrKlyeLjNMDq9zMkpBKkbuyhnQUCfO1A%3D)
