The agreement between you and CalcNex governing your use of the Platform
These Terms of Service ("Terms") govern your access to and use of the CalcNex engineering calculation platform ("Platform") operated by CalcNex ("we", "us", "our"), an Australian sole trader business.
By registering an account, accessing the Platform, or clicking "I agree", you confirm that you have read, understood, and agree to be bound by these Terms. If you are accepting these Terms on behalf of an organisation, you represent that you have the authority to bind that organisation.
If you do not agree to these Terms, do not use the Platform.

All prices are in Australian dollars (AUD) and exclude GST. Subscriptions are billed monthly in advance via Stripe.
Each subscription plan includes a maximum number of user seats: Free (1 seat), Essential (1 seat), Professional (2 seats), Enterprise (4 seats).
