Your calculator inputs
Everything you type into a calculator stays in your browser. It never reaches us.
Calculator inputs you type — a birth date, a loan amount, a test score — are processed entirely in your browser. They are never sent to a server, logged, or stored anywhere. Every calculator on this site runs as client-side JavaScript: your numbers stay on your device.
This is a consequence of how the site is built, not a policy we could quietly change: the site is static, and the calculation code runs on your machine. There is no endpoint receiving your inputs.
What we don't currently collect
No accounts, no tracking cookies, no analytics, no ads, no mailing list.
CalculatorPlanet does not require an account, does not use cookies for tracking, and does not currently run third-party analytics or advertising. There is no mailing list sign-up and no data broker relationship of any kind.
What may change
If we ever add analytics or ads, this page gets updated before they go live — not after.
If that changes — for example, if we add privacy-respecting analytics to understand which calculators are most useful, or turn on advertising to help cover hosting costs — this page will be updated first, with the "last updated" date above reflecting the change, before any such service goes live.
Server logs
Our host keeps standard request logs, used for security and uptime — not for profiling you.
Like virtually every website, our hosting provider's infrastructure generates standard server logs for requests (IP address, browser type, timestamp, page requested) used only for security and reliability purposes — not for tracking individuals or building profiles.
Third-party links
We link out to sources. Those sites have their own privacy rules, which we don't control.
Pages on this site link to external sources (government agencies, research organizations, and similar) for citations. Those sites have their own privacy practices, which this policy doesn't cover.
