Data Ownership

This year I am taking better care of my digital life. There are two aspects I want to improve:

I would like to own my photos, words, contacts, and files. I want to have the knowledge that no one else can access them if I don't want them to, and delete them if I see fit. A good fraction of them is still in the hands of third parties, and I would like to mitigate that.

In the past I have kept my files disorganized, and oscillated between hoarding and purging. This is not a very effective behavior: at times I want to look up something I realize I too eagerly deleted, or I even forget I have the thing I want, lost in the myriad of useless noise.
