Maybe you might know. I assume most webpages and native apps are harvesting all data available that they can get their hands on that the users/OS will let them take and then selling that off to the highest bidder. Including information that is completely unrelated to the operation of the application. Seems like you can make correlations with almost any type of data these days so I imagine even things that seem useless to capture could be valuable in the future.
