Privacy Policy
Last updated: August 26, 2026
1. Our Client-Side Architecture
At PrepaymentCalculator, your financial privacy is our highest priority. All mortgage calculations, loan balance simulations, interest rates, and extra payment projections are calculated entirely inside your web browser (client-side JavaScript).
None of your loan balances, income details, or debt figures are ever transmitted to or stored on our servers.
2. Cookies & Local Storage
We use your browser's localStorage solely to remember your preferred currency symbol (e.g., $, ₹, £, €) and theme preference (Dark or Light mode). This information never leaves your device.
3. Third-Party Analytics & Services
We may use privacy-respecting website analytics to track anonymous aggregate metrics like total page views and browser compatibility. These analytics do not capture any personally identifiable information (PII) or financial inputs.
4. Third-Party Links
Our site may contain links to official banking portals, lending institutions, or regulatory guidelines. We are not responsible for the privacy practices or content of third-party external websites.
5. Contact Us
