Your numbers stay yours
OnlyCalculators is built to be useful without watching you. Here's the plain-English version.
Calculations run in your browser
Every calculator computes locally on your device. The values you type, your weight, your salary, your measurements, are never transmitted to our servers, because there is no server doing the math.
No accounts, no profiles
You don't need to sign up to use anything here, and we don't build advertising profiles. When you copy a result link, the inputs are encoded in that URL so you can share or revisit them, that link is only created when you ask for it.
Analytics
If we measure traffic, we use a privacy-friendly, cookie-free analytics tool that records anonymous, aggregate page views only, never personal data. It is disabled by default and, if enabled, does not track individuals across sites.
Embedded calculators
Our embeddable widgets load only the calculator and an attribution link. They set no tracking cookies on the sites that host them.
