Software licence terms

VPQ Audit is licensed, not sold. Until a full end-user licence agreement is published here, these terms and the licence key or written agreement you receive from ATK govern your use.

What a licence key grants

Each key names the customer, the edition (trial, engagement, team, business or partner), the expiry date, and the maximum number of hosts and users. You may install and use the software within those limits for your own organisation, or, for a partner licence, for the clients named in your agreement. When the key expires the product stops producing unwatermarked reports.

Payment and refunds

Fees are invoiced or paid by PayPal before the key is issued. If we cannot deliver a working installation or, for the PQC Readiness Audit, the analyst review, we refund the fee in full. Write to support@atkvn.com.
