4. Engineering disclaimer

The toolkit provides screening-level and engineering-level estimates based on published correlations and documented assumptions. Results depend entirely on the inputs and assumptions chosen by the user. They are decision support, not a substitute for competent engineering judgement, site-specific assessment, or the applicable codes and standards. All outputs must be reviewed and approved by a qualified engineer before being used in design, operations or safety decisions. The platform is provided “as is”, without warranty of any kind, and RiskCalcs accepts no liability for any loss or damage arising from its use.

The platform is under continuous development. Modules, methods, data and these terms may change without notice. Continued use after a change constitutes acceptance of the revised terms.
