Privacy Policy
Last Updated: September 2026
1. Our Privacy Commitment
At TongueWeight.com, we believe trade utilities should not track users. Our calculations run 100% in your local browser runtime. Your trailer specifications, scale weights, and vehicle ratings are never stored on or transmitted to our servers.
2. Local Storage and Client-Side State
We do not collect personal identification information (PII). We do not set tracking cookies or use third-party analytics trackers. Standard browser localStorage is used for a single purpose:
theme: Remembers your preferred interface visual contrast setting (dark or light mode).
3. Device Permissions & Clipboard Access
Our copy functions utilize the browser's native Clipboard API (navigator.clipboard.writeText) strictly upon user initiation (clicking "Copy Specification"). We never read from or monitor your system clipboard.
