Privacy Policy & Client-Side Security
Last updated: September 2026 • VanBuildCalculator.online is engineered with a strict client-side first architecture where your build data never leaves your browser.
1. 100% Client-Side In-Browser Computation
Unlike traditional web applications that transmit form data to remote servers for processing, VanBuildCalculator operates entirely within your browser's local JavaScript runtime.
When you enter vehicle dimensions, battery capacities, electrical loads, or heating specifications, all mathematical calculations occur instantaneously on your local machine. None of your inputs, vehicle choices, budget estimates, or appliance lists are ever transmitted to, logged by, or stored on our servers.
2. Zero Third-Party Advertising & Tracking Cookies
We maintain an uncompromising stance against behavioral advertising networks and surveillance capitalism:
- Zero Tracking Pixels: We do not load Facebook Pixels, TikTok trackers, Google Marketing Platform remarketing tags, or third-party behavioral scripts.
- Zero Cross-Site Tracking: We do not sell, rent, monetize, or disclose user data to data brokers or advertising exchanges.
- No User Fingerprinting: We do not deploy canvas fingerprinting, audio context fingerprinting, or battery status tracking techniques.
3. LocalStorage & Session State
To improve user experience, our tools may utilize your browser's standard localStorage API solely to preserve your active calculator inputs across browser tab refreshes. This data remains strictly inside your local browser sandbox and is never transmitted over the network. You may clear this data at any time via your browser settings.
4. Cloudflare Edge Delivery & Infrastructure Logs
This website is hosted and delivered globally via Cloudflare Pages edge network. Standard, non-identifying server logs (such as IP addresses and user-agent strings) are processed by Cloudflare at the edge solely for DDoS mitigation, bot defense, and HTTP caching, in accordance with Cloudflare's strict Enterprise Privacy Policy.
5. GDPR & CCPA Compliance
Under the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), you retain full rights over your data. Because we do not collect, process, or store personal identifiable information (PII), your browsing and calculation activities on this platform remain private by design.
