We collect minimal information. Specifically:

• Email address — only if you voluntarily sign up for our interest list. We use your email solely to send you updates about Metarium.
• IP address and browser user-agent — collected when you submit the interest signup form. This data is used for spam prevention and abuse detection.

We do not use cookies, analytics trackers, or any other form of user tracking beyond the signup process described above.

How We Use Your Information

Third-Party Services

This website uses the following third-party services:

• Google Fonts — for typography. Google may collect limited technical data (such as IP addresses) when fonts are loaded. See Google's Privacy Policy.
• Cloudflare Turnstile — for bot protection on our signup form. When you submit the signup form, Cloudflare processes your request to verify you are human. Cloudflare may collect technical data as part of this verification. See Cloudflare's Privacy Policy.

We do not control these third parties' data practices.
