"Your data" assumes there is some sort of Doppelganger attached to a data bundle which is mostly hot air and used to persuade those who buy from data brokers that the data is in-fact correct. I know some FOIA pests who are purposefully polluting such data-sets and then asking for the information and seeing some very skewed results. What if I sell back my data, since that's what they're after anyway? I keep more logs than brokerages and would be happy to hand them over for a fee. One item of browsing history alone is probably worth upwards of $10,0,00
