This website
gaiya.cc collects nothing. There is no analytics script, no advertising network, no cookie, and no login. The site is a set of static files served by Cloudflare, which keeps standard server request logs.
Your theme preference is stored in your own browser's local storage so the page remembers it. That data never leaves your device.
