Privacy Policy

Calculation inputs

Calculator inputs and results are processed in your browser. This distribution has no account system, analytics tag, advertising tag or calculation backend. Entered values are not submitted to a calculation server. A link shared through the site contains the page address without input values.

Information saved on your device

The site can save theme, currency and number-format preferences, favorite calculator identifiers and recently used calculator identifiers in localStorage. It does not save calculation inputs or results. You can clear this data using your browser’s site-data controls. Private browsing or disabled storage may prevent persistence.

Hosting and third-party links

Like other websites, the hosting provider may receive network information such as your IP address, requested URL and browser headers. Hosting logs, retention and access are controlled by the operator’s hosting configuration. External reference links open third-party websites whose privacy policies apply separately.

Copying, sharing and feedback

Copy actions write the selected text to your clipboard when permitted. Downloads create files on your device. The Web Share interface sends information only to the destination you choose. The contact feedback report is created locally and is not sent automatically.

Changes

If analytics, advertising or a server feature is added, this policy must be updated to identify those services, their data use and applicable consent controls before deployment.
