Calculator inputs

The tools calculate in your browser. This site does not send entered dates, times, or payment amounts to a calculator server. Do not enter account identifiers or personal information. There are no account forms and no own analytics or tracking scripts in this staged site.

The browser downloads local HTML, CSS, JavaScript, and the official-data JSON file. The calculator inputs are not saved to local storage or placed in the page URL. Reloading a page restores its initial illustrative inputs.

Third-party advertising

Advertising containers are reserved for possible future ads. Third-party ads, including Adsterra, may set cookies or use similar technologies when advertising is added. No advertising script is included in this staged version. Browser privacy settings can restrict cookies and third-party storage.

Links and hosting

Official source links open the relevant external website when you choose to follow them. That website applies its own privacy practices. The calculators do not fetch those external pages during use.

The static site does not implement server logging. Hosting software may maintain request logs according to its configuration. This page does not claim to disable hosting logs that are outside the static site files.
