Privacy

How this default website handles calculator inputs, bookmarks, and ordinary web requests.

Published September 15, 2026

Calculator inputs stay in your browser

The supplied calculators run locally in JavaScript. The site does not upload or persist calculator input values or results. Changing pages or closing a tab may clear those values. Copying, printing, or exporting a result is an action you choose; the resulting file or clipboard content is then under your control.

Bookmarks on your device

The bookmark feature stores only calculator identifiers in your browser's local storage under the key cc-bookmarks. It does not store your calculations. Remove individual bookmarks using the bookmark buttons, or remove all saved data by clearing this site's browser storage.

Hosting and network requests

Your browser requests website files from the hosting service. The hosting provider, network, or security service may process standard request information such as an IP address, browser information, requested URL, and access time. That is separate from calculator input processing. Retention and handling of hosting logs depend on the operator's provider and settings.

No advertising or analytics scripts in this release

This supplied version contains no advertising network, analytics tracker, external font service, or account-registration system. It does not set application cookies. If the site operator later adds analytics, advertising, forms, or other integrations, this notice and any required consent controls must be reviewed and updated before those integrations are enabled.

External links

Reference links lead to independent websites. Their privacy practices apply after you follow those links. No calculator inputs are added to the reference URLs.

Questions

Contact details, when configured by the site operator, are shown on the About page. Do not send sensitive financial details or personal identifiers in a public message or ordinary email.
