Most calculator inputs are processed in your browser and are not intentionally sent to CalcNator's server. Some tools require external services. For example, the Currency Converter requests exchange-rate data from ExchangeRate-API, and the QR Code Generator uses an external QR image service. Information entered into a tool that explicitly identifies an external service may be transmitted to that provider.
