Privacy Policy

Plain-language summary — last updated with the site's initial release.

The short version

• You can use every calculator without an account. We never ask for your name, email or financial details.
• All calculations run locally in your browser. No calculation data is sent to or stored on a server.
• We do not use tracking cookies or advertising pixels.

Local storage

Your browser stores a few small preferences locally: your chosen currency, light/dark theme, and optional saved calculation history. This data never leaves your device. It may not transfer between devices or browsers, and clearing your browser storage removes it.

Shared calculation links

The Share button creates a URL containing only the calculator inputs (principal, rate, duration, method, currency). Anyone with the link loads the same numbers — don't include amounts you consider private in calculations you share.

Changes

If this policy changes materially, the update will be published on this page with a new "last updated" note above.
