Privacy Policy

Effective July 2, 2026 · wbcheck.com and the WBCheck app

The short version

WBCheck collects no personal data. There are no accounts, no analytics trackers and no ads.

What stays on your device

Your load inputs, unit preference and the empty weight / CG you enter from your aircraft's weighing record are stored in your browser's or app's local storage, on your device only. They are never transmitted to us. Clearing site data removes them.

Purchases

In-app purchases are processed by Apple's App Store or Google Play. We don't receive your payment details. Purchase receipts are validated through the store's standard mechanisms.

Server logs

Our hosting provider (Cloudflare) keeps standard, short-lived operational logs (like request counts and error rates) to keep the service running. We don't use them to identify you.
