My personal solution is to obfuscate my online data. I have many disparate identities online which I think makes it a bit harder to be targeted directly. I know that a concerted attack could easily tie my data together but I think I am not significant enough for anyone to bother with me. As a result I see very generic advertising.
Simple solution to this specific issue is to get a cheap second phone and drop the app on that. Leave it at work or in the car turned off when you are off the clock.
What I am curious about is how valuable is this sort of GPS data specifically. Especially for lower socio economic people, who for the time being seem to be the ones that are targeted with this sort of pervasive monitoring. I’m at a loss for actual valuable ideas to do with a knowledge of poor peoples movements that I couldn’t get from some generic anonymous socio economic data.
