Privacy policy

Calculator inputs are processed locally in your browser. The calculator code does not send them to a server, put them in a URL, or save them in cookies or browser storage. Reloading the page returns the form to its source-example defaults.

Tracking and page requests

This site does not include its own analytics or tracking scripts. Loading a page requires ordinary requests to the hosting server for HTML, styles, and JavaScript. The hosting infrastructure may handle technical request information in its standard logs. The calculator does not request personal details or require an account.

Advertising

This staged version reserves space for advertising but contains no active ad scripts. Third-party ads from Adsterra may be added later. If served, those providers may set cookies or use device and request information for advertising, delivery, and measurement. Their handling of that information is separate from the local calculator logic. Browser privacy controls can manage cookies and other site data.

Official source links

Links to official references take you to their websites. Those services have their own privacy practices. The site does not load those sources in the background when you calculate a result.

This policy describes the files in this site as of October 5, 2026. Read about the tools for calculation methods or return to the cumulative interest calculator.
