Most calculator sites are ad-farms that sell your data. We built the opposite. A privacy-first, open-source stack for Finance (Mortgage, Affordability, Debt Payoff) and Time (Business Days, Work Hours). Zero ads. Zero tracking. Instant client-side logic. Stop giving your financial data to lead-gen forms; just get the math you need and get back to work. Obviously, it's free.
Most PDF tools require you to upload your sensitive files to a random server. We built a privacy-first alternative.
