I have a Facebook account on which I have shared as little as possible. When I downloaded the data off the platform, it was completely empty which was no surprise.

But, as it turned out my friends were not so lucky. All of them had my number saved. Some had my birthday. Quite a few had tagged me at my work location etc.

So, even with efforts on my side to try and not share data, FB still has a profile on me. I find it hard to believe that there are lot of other platforms which can build such a cache of information about me, without me giving them explicit permission.
