Privacy Policy

Prepared October 30, 2026. This notice describes the local Lineproof implementation. A verified publisher identity, monitored contact channel and production hosting review remain prerequisites for public launch.

Calculators and checklist

Calculator values are processed in your browser and are not submitted to a server by this application. Checklist selections are saved in this browser’s local storage. Reset clears the selections; your browser settings can remove the stored data. Do not enter confidential production information or personal data.

Search and connections

Search uses a static index downloaded from this site. A search phrase in the page URL can remain in browser history and is included when that URL is requested from the local server. The page and asset requests necessarily reach the server. This implementation does not add analytics or collect leads.

Advertising and external sources

No AdSense client, advertising scripts, third-party tracking pixels or external font services are configured. Official reference links take you to other websites with their own practices.

US privacy review

Privacy obligations depend on the operator, processing and applicable law. The California Privacy Protection Agency FAQ explains CCPA rights and business applicability. This local preview does not assert that the operator meets or is exempt from a legal threshold. The publisher must assess applicable state requirements, hosting logs, retention and request handling before launch or adding advertising.

Requests

There is currently no verified publisher contact channel. See Contact for this unresolved status. No request form is offered and no assurance of a response is fabricated. The publisher must supply the actual contact and update this notice before public use.
