# How to export evaluation data
GO Feature Flag allows for the collection of flag usage data.
During flag evaluation, the key, flag variation and other non-sensitive information used are collected and cached for a
configurable period of time.

The usage data is then written to a file in a chosen format (`parquet`, `JSON` or `CSV`) at a specified interval and
exported to your desired location. This provides a single source for easy processing of the data. The feature can be
configured with options for file format, flush interval, and file location.

To use, simply configure, use the feature flag as normal, and analyze the collected usage data.
