people will hate about this, but as long as you didn't installed malware, and you blocked pirated software with firewalls (simplewall:https://github.com/henrypp/simplewall), you can have "privacy" because it never connects to internet and you don't give anyone information. so shoot for it if you want.
Mint is always recommended because it just works, it looks windows-like, it's legit fine no it doesn't look dated or ugly. Cinammon is hot.
