Privacy policy
How this site handles analytics, external links, and information you choose to send.
Last updated: August 1, 2026
Access data and analytics
The hosting provider may process access logs for delivery and security. GA4 loads only when NEXT_PUBLIC_GA_MEASUREMENT_ID is configured, and is designed to record page activity and non-personal interaction events—not calculator inputs. Without that setting, no Google Analytics script is loaded. We also use Vercel Web Analytics to understand site usage and improve the site. Vercel Web Analytics does not use cookies and processes anonymized, aggregated information.
Calculator inputs
Free-tool inputs are calculated in your browser and are not stored by our server. Tool-use analytics events are designed not to include the values you enter.
External links and contact
External services apply their own privacy policies. GitHub Issues are public, so do not post personal, health, or confidential information.
