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.
