Terms of use

Draft for the proof of concept. To be replaced by terms reviewed by a lawyer before commercial launch.

The service

ChemEngWorks provides engineering calculations as a service. Results are screening estimates from the methods described on each calculator page. A competent engineer must check them before relying on them in design, safety or operating decisions.

Credits

Calculations are paid for with prepaid credits. The price of a run is shown on its Run button before you start it, and the charging rules are shown on the Credits page. Credits do not expire. Credits are not money and cannot be exchanged for money except as the law requires.

Acceptable use

You must not try to reverse engineer, extract or reproduce the calculation methods, data or software, including by systematic probing of inputs and outputs, and you must not try to get around rate limits, quotas or security controls. We may suspend accounts that do.

Your data

Your inputs and results remain yours. How we handle personal data is described in the privacy notice.
