Today I tried the data detox kit on myshadow.org and I learned quite a few things I did not know, even though I care about my privacy.
One of the most important things one should know is that you can actually influence what data is collected on you — even if you do not want to give up on using certain services. Many offer settings where you can view and delete data they have on you, and you can disable data collection in the first place.
I found it impressive to see all the data Google has on me by visiting the Google My Activity page. And I was relieved to find what they do not have, because I have carefully adjusted the privacy settings on my account.
Even if you do not feel the need to change anything, I cannot recommend highly enough to take the tour they have created. Just seeing what others know about you is scary — and may change your mind.
Btw, I also disabled various default settings of this blog which enable tracking, like the social media sharing buttons. Many more are out of my control since it’s a free blog though. Especially the ads displayed here and not run by me, but by wordpress.com and/or their partners. You can use tools like ADBlock or Privacy Badger by the EFF to get rid of them.
