PRIVATE BY DESIGN

Calculations run on your device. The numbers you enter, your results and search text are not sent to analytics or advertising. Saved history is stored locally and excluded from cloud backup. Optional anonymous usage and crash sharing is off by default and can be changed in Settings.

Most tools work offline. Live currency-rate refresh needs an internet connection; cached rates remain available offline. OmniCalc is ad-supported when consent permits. An optional one-time Remove ads purchase hides advertising. No account is required.

IMPORTANT

Financial, health, tax, construction and engineering results are estimates for general information. Check important decisions with a qualified professional and the relevant authoritative source.
