Last year I tried to buy a mahjongg game for my iPad. My requirements:

  No subscription
  No hoarding my personal data
  Updated in the last year or so

I couldn't find a single one. They're all subscriptions, slurping up personal information, or not updated in a very long time so they can continue to fly under the radar and not report what data they're selling about me.

I'd pay $20, maybe $25 for an app the just let me play a simple tile game. But greed rules the app world.
