Mortgage Math is designed so that your financial information never leaves your device.
Nothing. Mortgage Math has no accounts, no sign-in, no analytics, and no advertising. We do not collect, store, transmit, sell, or share any personal information.
Everything you enter — income, debts, savings, home prices, saved calculations — is stored only in the app on your phone. Deleting the app deletes this data. We have no servers that receive it and no ability to see it.
Some features look up public information over the internet. These requests do not include your personal or financial details:
These third-party services (for example redfin.com, duckduckgo.com, census.gov, cfpb.gov) receive standard technical information inherent to any web request, such as an IP address, subject to their own privacy policies.
Mortgage Math is a general-audience financial calculator and does not knowingly collect information from anyone, including children.
Mortgage Math provides educational estimates based on published guidelines and public data. It is not a lender, broker, or financial advisor, and its results are not a loan offer or approval.
If this policy ever changes, the updated version will be posted at this address with a new date.
