TERMS OF SERVICE - SHORT VERSION 1. We do not guarantee that the service will be uninterrupted or error free. 2. We do not make any warranty as to the quality or usefulness of the calculation results that may be obtained from use of the service. 3. Your data may be deleted one month after the creation of your trial account, unless you register for a full account. You will be provided 300 CPU-seconds to perform calculations on CalcUS Cloud, with common calculations taking between 2 and 10 seconds. Conformational searches use much more computing power; to avoid spending all your computation time, use them only for small molecules at the GFN-FF theory level or register for a full account.
