Sibling comment does a great job, but I just wanted to add that their Terms and Privacy Policy are simply not compatible with privacy-friendliness.

I used to analyse PPs to detect usage of data brokers, and I’ll confidently say that these 2 have some of the worst policies out there, although less obvious companies such as Netflix and Spotify also had appalling conditions.

If a policy is compatible with data brokerage, you can very well assume they do it, and that means they’ll share your data and get shared data about you in return. But hey, “we don’t SELL your data!”
