Privacy / updated 5 October 2026

A small site.
A clear data boundary.

The informational site has no contact form. Commerce now uses a separate D1 runtime, with production checkout locked until commercial approval.

Site requests

Cloudflare delivers this website and may process request metadata such as IP address, user agent, time, and security events under its service policies. Operational account metrics are not a customer analytics database.

Cookies and analytics

No marketing cookies, third-party analytics scripts, or advertising trackers are configured by this application. Cloudflare security features may operate at the hosting layer.

Downloads and calculator

Toolkit files are downloaded to your device. Calculator inputs are processed in your browser, are not saved by the site, and are not submitted to a server. Do not enter identifiable customer information.

External contact

GitHub enquiries are public and handled under GitHub’s policies. Do not submit sensitive information. A verified private email and formal privacy contact are pending owner confirmation.

Scope and review

Commerce stores cart items, immutable order snapshots, customer name/email, and payment references in Cloudflare D1. Private cart/order access tokens are kept in session storage on your browser; only their hashes are stored by the server. An enabled checkout sends the necessary order and customer information to Duitku for payment processing. No card details or API credentials are stored in this application. Browser payment messages do not determine payment status. Production checkout remains locked pending approval of the real product, customer support, refund/cancellation terms, and data retention/contact arrangements. Do not submit real customer data while testing.
