Almost nothing. The site remembers only your language choice (English/Japanese), stored in your own browser's local storage so the site works the way you left it when you return. The dark theme is fixed for everyone. No accounts, no tracking cookies, no advertising trackers are set by this website.
The contact form does not send anything to a server. It opens your own email app with a pre-addressed message, so your words travel through your email provider like any normal email.
Links and embeds point to YouTube, Instagram, Facebook, TikTok and Spotify. When you follow them, those platforms' own privacy policies apply. Live counters and video feeds, when enabled, are fetched from those platforms' public data.
