Model boundary

RainLab is an offline educational reduced-order model. It is not professional drainage design, flood forecasting, emergency guidance, or a calibrated site prediction. Read the assumptions and limits shown with each result.

Privacy

RainLab does not require an account or network connection. See the Privacy Policy for the app’s data and export behavior.
