Calculator inputs
Calculator inputs and results are processed in your browser. The public beta does not intentionally transmit or save those calculation values to an M&H Engineering LLC customer database.
Infrastructure and analytics
Our hosting and security providers may process routine technical information such as IP address, browser type, requested page, timestamp, response status, and performance measurements. We use Cloudflare Web Analytics for aggregate, cookie-free traffic and page-performance reporting. It is not used to build advertising profiles.
Cookies and accounts
The public beta does not provide customer accounts, payment processing, or application-level advertising cookies. Infrastructure providers may use essential technical mechanisms required to deliver and protect the site.
Links and retention
External technical-reference links are governed by their respective privacy notices. Infrastructure and aggregate analytics information is retained according to the applicable provider settings and operational needs.
Changes
This notice will be revised before memberships, saved calculations, payments, or additional personal-data features are introduced.
