Why Are These Free?

CalcIQ is a privacy-first calculator platform. We don't sell user data (we don't collect any). Free embeds serve two purposes:

• For you: Interactive content that keeps visitors on your blog longer, improving engagement and SEO
• For us: Each embed includes a small "Powered by CalcIQ" attribution link. More embeds = more visibility = more direct users discovering the platform

That's the entire business model for free embeds. No tracking, no data harvesting, no hidden costs. The calculators perform all math locally in your visitor's browser — we literally cannot see what numbers they enter.
