Cookies and browser storage

WaterCalcLab uses cookies and local browser storage for technical features and preferences. Cookies are sent to the relevant server; local browser storage initially remains on your device.

Essential features

Administrator sessions require cookies for sign-in and form protection. The application stores unit and optional-service choices under entries prefixed with watercalclab:. Optional-service choices are reassessed after 180 days.

Statistics and optional services

Google Analytics 4 may set statistical cookies. The optional-services control manages the optional integrations connected to it; it is not a general browser block for every external service. The privacy policy explains Analytics. Advertising services load only when configured on the website and the required permissions are present.

Managing preferences

Change your optional-service choice through cookie settings in the footer. You can also delete or block cookies and local storage in your browser. This may remove saved preferences and administrator sign-in. You can also block Google Analytics using https://tools.google.com/dlpage/gaoptout.
