Questions you probably have
Yes. Every calculator, every result, forever. ZeroNova has no paid tier, no credit card requirement, and no trial period. You create an account with email and password, and every tool is yours to use unlimited.
Two reasons: to unlock your calculation results, and to save calculations you want to revisit later. No spam, no data selling, no email sequences. The account exists so you can pick up where you left off.
The math is the same whether you sell fashion, electronics, home goods, or beauty products. Profit margin is profit margin. ROAS is ROAS. The calculators adapt to whatever numbers you enter, so they work for Shopify, WooCommerce, Etsy, Amazon, or any other platform.
That is the best time to use them. Run the numbers before you order inventory, before you run ads, before you commit to a product. Find out if a product is viable on paper before you spend real money.
No. ZeroNova runs entirely in your browser. Nothing to download, nothing to update, no browser extensions. It works on Chrome, Safari, Firefox, and Edge on any device.
