For a "privacy-focused" search engine that's "operating in “no tracking” mode by default" I find "only" 9 trackers 9 too many TBH.

Maybe they'd get on steady if you asked them. Many people are very cooperative when there's money to be made.

For little fun projects I really like uberspace.de. it's a shared hosting platform, basically you get a user account on one of their Linux servers where you can login and do whatever you want. Price is 10€/month by default but you can go down to 5€ if you're low on cash. They let you pick your own price, just try to be fair. You can't register domains directly from them but your account comes with a yourname.uber.space subdomain and setting up domains you bought somewhere else is super easy too, they also take care of SSL certificates automatically. They also have a lot of documentation about how to run practically any service you'd want there. Here's the page for flask for example: https://lab.uberspace.de/guide_flask/

EDIT: German company run by some nerds that are really helpful if you need something.
