Privacy

This website has no analytics or advertising trackers, registration or payment form. The calculator runs locally. YouTube connects only after a notice and your action. GitHub Pages, image servers and external websites may process technical connection data under their own policies.

Searching site materials takes place in your browser. After separate consent, “Ask AI” sends your question, language and up to three recent pairs of AI conversation messages through Cloudflare to OpenAI; long previous answers are shortened. Calculator values are not sent. Cloudflare and OpenAI process requests and technical data under their own terms. Do not send personal, confidential or tax details. This site does not save conversations on its server or in browser storage. Response storage is disabled for the OpenAI request, but providers may still process and retain data for service operations. Clearing the conversation removes its local history; closing the window withdraws consent and clears AI context. This does not delete data already sent to providers. AI can make mistakes: check VMI sources.

This site uses no advertising or analytics cookies. YouTube loads only after a separate click. Your browser saves acknowledgement of this notice and whether the parish appeal has been shown; the latter lasts until the tab is closed.
