Launch promotion: official rules

These rules set out the terms of the promotion announced on qcalculatrice.com for contractors: the temporary free project files and the credit draw among the first activated accounts. They supplement the Terms of Sale (contractors), which continue to apply. By creating a contractor account during the promotion, you accept them.
