Privacy Policy

Calcerra is a free collection of online calculators. We have built it to need as little of your information as possible — this policy explains exactly what that means.

Your calculations stay in your browser

Every calculator on Calcerra runs entirely in your browser. The numbers you enter — loan amounts, income, weight, anything — are never sent to a server, never stored, and never seen by us. When you close the tab, they are gone.

Shareable links

Some calculators let you copy a shareable link. That link encodes your inputs in the URL itself so you can bookmark or send it. The data lives only in the link you choose to share — we do not receive or record it.

No accounts

Calcerra has no sign-up and no login. We do not ask for your name, email, or any personal detail, because the site does not need them.

Analytics

We may use privacy-respecting, aggregate analytics to understand which calculators are useful and how the site performs. This measures page visits in aggregate — it does not identify you and does not capture the values you type into a calculator.

Cookies

Calcerra does not use tracking or advertising cookies. Your browser may store small preferences (such as a chosen unit) locally on your device; this never leaves your device.

Changes to this policy

If this policy changes, the updated date above will change with it.
