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 to understand aggregate traffic patterns — which pages are visited and how often the calculator is used. This helps us improve the tool. Analytics are privacy-friendly, don't use cookies, and can't identify you personally.
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 or third-party tracking
We don't run ads, sell data, or embed third-party trackers. No advertising networks, no cross-site tracking, no remarketing pixels — nothing that follows you around the web.
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.
