Elementium is an interactive educational web application offering a periodic table of elements enhanced with 3D visualizations, quiz tools, element comparison, a molar mass calculator and educational chemistry content.

The Premium subscription is offered in two plans: monthly (€4.99/month) and yearly (€24.99/year). Payments are processed securely via Stripe.

The subscription renews automatically at each billing date. You can cancel at any time from your Stripe customer portal. Cancellation takes effect at the end of the current period — no partial refund is granted.
