This GPT directly collects no data regarding your queries provided, and does not give Open AI permission to train its models 
on the conversations with the GPT

It does use the Power Query formatter API, documented at https://www.durchblick-durch-daten.de/power-query/m-formatter/ 

This formatter does not collect any metadata, with the exception of Error tracking. 
It does track Errors that occur during formatting in order to fix bugs and improve their service. 
In these cases metadata about the error is sent to the azure app insights remote service which contains a stacktrace. 
This stacktrace might indirectly contain some information about the query that caused the error
