Privacy
DeductMate is built privacy-first. Your calculator inputs stay in your browser, and the only data we collect is aggregate, anonymous traffic stats.
No accounts, no data stored
DeductMate's calculators run entirely in your browser. The numbers you enter never leave your device — there's no server, no database, and no account to create. Close the tab and the inputs are gone.
Anonymous usage analytics
We use Vercel Analytics (cookieless) and Google Analytics to understand aggregate traffic patterns — which pages are visited and how often the calculator is used. This helps us improve the tool. Google Analytics may set a small analytics cookie (_ga) to tell repeat visits apart; it is used only for usage statistics, never for advertising, and can't identify you personally. You can opt out anytime with Google's official browser add-on (tools.google.com/dlpage/gaoptout).
Core Web Vitals monitoring
Vercel Speed Insights collects performance metrics (like page load time) from real visits so we can keep the site fast. This data is aggregated and doesn't include personal information.
No advertising, no data selling
We don't run ads, sell data, or do remarketing. The only third-party services on this site are the analytics tools above (Vercel Analytics and Google Analytics), used solely to measure aggregate usage of our own pages. No advertising networks, no cross-site ad tracking, no remarketing pixels.
External links
Links to IRS and SSA official sources use rel="noopener nofollow" — we don't endorse or control third-party sites, and they open in a new tab so you can verify the rules yourself.
