Privacy Friendly Apps – improved privacy protection on the smartphone

I have a Samsung phone, s10+. I've not tried this app yet, but I will. However all apps I've tried so far got my steps wrong. I imagine because it's something that isn't documented by Samsung and they know exactly which values to use to calculate the steps and distance and speed.

So essentially you buy a product with the right sensors but there is no documentation for you on how to use those sensors to have near accurate conversion results if you're going to write software that uses those sensors.

If you know better, please let us know.

I don't wish to knock this great project, but I'm growing weary of reading what seem to be almost obligatory structures;

  1) Initial platitude about how smartphones are ubiquitous,
  inevitable, inescapable centres of existence without which humans
  would die within seconds.

  2) Tragic self-mocking account of how we're all idiots without
  self-control who can't work these things, but remain utterly
  dependent on technology we have no clue about.

  3) Confusing, terrifying litany of all the evil-doers, hackers,
  cybercriminals, corporations, agencies, and other bad guys f-king us
  over, while trying not to sound paranoid and hopeless.

  4) Optional apologetics justifying unconscionable shitshow of (3) on
  the basis of convenience and getting stuff for free. 

  5) (Point at which most normies stop reading) Solution involving
  jaibreaking, firmware updates, running a private VPS server,
  building your own DNS network and soldering in some new chips using
  dangerous solvents, X-Rays and a x100 bench microscope.

  6) Shrugging summary about how this "probably isn't for everyone".
