Zero-Data Privacy Policy
Effective Date: August 20, 2026
Our Core Privacy Guarantee
We do not collect, store, transmit, or monetize your personal physical information. Every single parameter you input into DIN Calculator Pro (weight, height, age, boot sole length, skier type) is processed entirely in your device's local memory (RAM) and is discarded the moment you close your browser tab.
1. Information We Do NOT Collect
- No Biometric or Physical Data: Your weight, height, age, and boot sole length are never transmitted to any server or third party.
- No User Accounts: There are no user sign-ups, passwords, logins, or member databases.
- No Tracking Cookies: We do not set persistent advertising, tracking, or cross-site profiling cookies.
2. Pure Client-Side Execution
DIN Calculator Pro is built using static site generation (SSG). When you visit the site, your browser downloads a lightweight TypeScript calculation script. When you adjust sliders or form fields, the calculations execute in <1ms directly on your device's CPU. Zero API requests or background network packets are sent during calculation.
3. Privacy-Preserving Web Analytics
To monitor site performance and understand general traffic volume, we may use privacy-first, cookieless analytics (such as Cloudflare Web Analytics or Plausible). These tools do not track individual users, do not use cookies, and do not collect Personally Identifiable Information (PII) or IP addresses.
4. Third-Party Hosting & CDN
This website is hosted on modern edge content delivery networks (such as Cloudflare Pages or Vercel). Standard web server access logs (such as request timestamps and HTTP status codes) may be collected automatically by infrastructure providers for network defense, DDoS mitigation, and reliability purposes.
5. Compliance with Global Regulations
Because we do not process, store, or sell personal identifying data, DIN Calculator Pro is designed from the ground up to comply with global privacy standards, including the European Union General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and UK Data Protection Act.
