This means:

All mathematical calculations happen locally on the user’s device.
Input values entered into calculators are processed only within the browser session.
Calculatorr Rex does not store, transmit, or log calculation inputs or results on our servers.

The data entered into calculators is not saved, recorded, or sent to any backend server operated by Calculatorr Rex.

Once the user leaves the page, refreshes the browser, or closes the session, the calculation data is automatically cleared from the browser memory.
