I try to make this site without JavaScript, I use Bulma Which doesn't require JS, but full disclosure, I've used a little JS for the mobile version (specifically the menu burger opening and closing). but this site will function if you turn JS off.
I do not store information, but cloudflare, does collect some information about what pages you visted, and what country you are from, the website is self-hosted on a raspbery pi, and I am working on moving the domain registrar from cloudflare, just need a little money first.
