TaxNinja collects no personal information. Every number you enter stays in your browser — we never see it, store it, or share it. Here's our full privacy policy in plain English.
TaxNinja never asks for your name, email, or any personal information. No account. No profile. Nothing.
All income figures and deductions you enter are processed locally in your browser using JavaScript. Nothing is transmitted to any server.
TaxNinja uses Google AdSense to display ads. AdSense may set cookies to show relevant ads. This is the only third-party data activity on this site.
TaxNinja is a free, client-side tax estimation tool built for US freelancers, 1099 contractors, and self-employed individuals. It runs entirely in your web browser — nothing you type is ever sent to a server. There are no user accounts, no sign-ups, and no data collection of any kind. This privacy policy explains our approach to data (or rather, our lack thereof), the limited third-party services we rely on, and your rights.
Nothing. TaxNinja performs every calculation locally using JavaScript. Your income, deductions, filing status, and any other information you enter stays on your device.
TaxNinja collects zero personal data. No name, no email, no financial records — nothing is stored on our servers because we don't have any.
Since we collect nothing, there is nothing to use. TaxNinja runs standard JavaScript math in your browser. No data is transmitted, stored, or processed on any server.

Your data is inherently secure because it never leaves your device.
