At Rivlosys, we believe your financial data is your business. Our "Privacy by Design" approach ensures your information remains secure.
All mortgage calculations are performed locally within your web browser. We do not transmit your purchase price, down payment, or income data to our servers.
We do not require accounts, logins, or personal identifiers (like names or phone numbers) to use our tools.
We use Umami Analytics, a privacy-focused, cookieless service, to track general site usage (e.g., page views) without identifying individual users.
Links to third-party sites (like Ratehub) are provided for your convenience. These sites have their own privacy policies which we encourage you to review.
