1/ There has been a lot of noise around Data Privacy since WhatsApp changed their T&C in order to share more data with Facebook. If you're worried about that, you should be really worried about Google. Disclaimer: This is just my personal opinion, so take it with a pinch of salt.

2/ Did you know that you could download almost all the data Google has on you? Try Google Takeout ( https://takeout.google.com/settings/takeout). It might take a couple of days to prepare your exports. But when it's done, look at the size of the download and tell me you're not surprised. I was.

3/ Google uses your activities to build an online profile of you (You remember 'The Social Dilemma'? Yeah, just like that). You can access your online alter-ego in Google's Ad Personalization ( https://adssettings.google.com/authenticated ). It's more accurate the more you use Google's services.

4/ Talking about Activities, Google records everything you do across devices and Apps. Go to My Activity ( https://myactivity.google.com/item ) to see it. This includes Web Activity, App Activity, Location History and Search History. Anything you've ever done online, Google probably knows.

5/ What's interesting about 'My Activity' is that it continues to store your data even if you've deleted it in the primary device. You have to delete it in the primary device AND 'My Activity' for Google to stop using it. If you don't, they will continue to use it.

6/ This is overlooked, but Google also stories the metadata of your Google Docs, Emails and so on. The Geotag on your Photos, the wordings on your Resume and details about every email you've sent, trashed or market as spam.

7/ To top it all off, Google uses AI tools as powerful as the AlphaGo Zero to analyze these data. I don't have to tell you much about AlphaGo Zero, but here's a nice summary from DeepMind themselves. https://deepmind.com/research/case-studies/alphago-the-story-so-far

8/ With algorithms as powerful as AlhpaGo Zero and a montainload of data, Google is poised to make the best out of it. It’s a virtuous cycle where Google understands what data it needs, how to better interpret it, how to better collect it and what else to collect.
