Who We Are

Lumi Guru (“Lumi,” “we,” “us”) operates the website lumi.guru. We provide a free diamond recommendation quiz and educational guides. We do not sell diamonds, jewelry, or any products.

Information We Collect

Quiz responses. When you take our diamond quiz, your answers (budget range, preferred shape, occasion, etc.) are processed in your browser to generate recommendations. We do not store your quiz answers on any server.

Analytics. We may use privacy-respecting analytics (such as Vercel Web Analytics) to understand how visitors use the site. This data is aggregated and does not identify you personally. It may include:

  • Pages visited and time spent
  • Referral source
  • Browser type and device category
  • Country-level location (no precise geolocation)

No accounts or personal data. We do not require sign-ups, collect email addresses, or ask for any personally identifiable information.

Cookies

We may use essential cookies required for the site to function and anonymous analytics cookies. We do not use advertising cookies or third-party tracking cookies.
