Privacy Policy

This informational site uses standard server logs. We do not request sensitive project or health information through the calculators.

Information handled by the site

This informational website may receive ordinary technical request data such as browser type, requested URL, time of access and general server diagnostics. The calculators operate as planning tools and are not intended for confidential, medical, financial or personally identifying information.

Third-party destinations

Links may take visitors to Amazon or another external resource. Those services operate under their own privacy policies and may use cookies or account information according to their terms. We do not control their checkout, account or tracking systems.

Your choices

You may browse the published research without submitting a project profile. Avoid entering sensitive information into any field on this site. Questions about a page correction should identify the public page and source rather than private household or business details.

Retention and security

Routine platform logs may be retained for operations, security and troubleshooting according to the infrastructure provider’s controls. No internet service can promise absolute security. Visitors should use the site only for general research and keep confidential building, customer and payment information out of calculator fields.
