In addition to the active conversion suite, our development roadmap on the Other Tools directory features upcoming client-side financial and mathematical calculators (such as Loan, Mortgage, and Percentage tools). These tools are architected to run strictly in-browser without sending user financial figures to remote analytics providers.
