Does Peakto write its meta data / categorization to each photos meta data?

Does Peakto write its meta data / categorization to each photos meta data?

Hi, 

The application finds and tags photos automatically with things it finds.
This information is then searchable. 

Does the new meta data exist in Peakto's database and/or 
it is written to the original photos meta data?

Which would then allow me to use that information in say Lightroom.
