About YouCanCalc

The site exists because most calculator pages bury the answer under ads and filler. Here, the answer comes first, the formula is printed next to it, and nothing else competes for attention.

Every tool runs entirely in your browser. Inputs are never uploaded, stored or sold — there is no account, no advertising trackers and no paywall. The only measurement on the site is privacy-first Cloudflare Web Analytics, which collects no personal data.

Who builds this

A small independent team of software engineers, working on the site directly rather than through a content mill. We are not doctors, dietitians, veterinarians or financial advisers, and the site never pretends otherwise: where a calculator touches health or money it names the published method it implements and points you to a professional for the decision itself.

How the formulas are chosen

Each calculator implements a method that already exists in the literature or in standard practice, rather than one we invented: the WHO scale for BMI, Mifflin–St Jeor for calories, Naegele’s rule for a due date, the UC San Diego epigenetic formula for dog age, standard amortization for loans. Where several conventions compete we pick the one a reader is most likely to be checking against — a spreadsheet, a clinic, a bank — and say which it is on the page. Where no authority exists, the tool says it is a convention rather than dressing it up as science.

Editorial rules

Each calculator states its method. Where results depend on population averages — pet ages, due dates, fertile windows — the page says so explicitly. We never invent ratings, reviews or statistics, and we don’t publish fake precision: a number is shown to the number of digits it is actually good for.

Corrections and review

If a result is wrong, that is a bug and it gets fixed rather than argued with. Report it to [email protected] with the calculator name and the exact inputs; we reproduce it, correct the engine, and add a test so the same error cannot come back. Health and finance pages additionally carry a "Method reviewed" line naming the source and the date a person last checked the implementation against it — when a method changes, or a page has drifted too long since its last check, it is re-verified and that date moves.
