Terms and Conditions of our
commercial software licensing

Individuals who have purchased and hold a personal use license may use our software on any of their personally and privately owned machines, networks and mass storage devices. We believe it's ridiculous to expect a private individual who owns multiple PCs and many drives to purchase separate copies for every machine or drive. In return, we ask that our software not be given to friends. Since it can be purchased and downloaded easily and immediately, they can have it quickly if you direct those individuals here.
Consultants who have purchased and hold a consultant / corporate site license may use our software on any of their client's machines.
Corporate sites may use:
  • SpinRite on multiple machines located at a single physical site if they purchase and hold a consultant / corporate site license.
  • DNS Benchmark at multiple locations with one separately-licensed copy per location.
Absolute Satisfaction Guarantee: Our products are licensed with a 30-day absolute satisfaction guarantee. If you are unhappy — for any reason — with your software purchase decision, you may write to within 30-days of your purchase to request and promptly receive a full refund of your purchase charge. Unless you instruct otherwise, the charge will be “reversed” with a credit for the charge amount applied to your card. If you contact our offices for this purpose, please state that the software in question has been removed from all computers and all copies have been deleted. Provide your email address, product serial number or the transaction code that appeared on your purchase receipt for the product you wish refunded. You will promptly receive an eMail confirming that the refund has been applied to your card.
Limitation of Liability: As is typical for all software products, except as otherwise provided for by prevailing law, the entire extent of our liability for the use of our software is limited to the product's purchase price. This is true even if we have been advised of and are aware of any problems with our software which may have caused trouble or unexpected or undesired consequences from its use. The software's user assumes and accepts the full burden of responsibility for all consequences of the use of the software. These necessary limitations notwithstanding, we have always made, and will always make, every effort possible to produce software that meets or exceeds the highest quality standards and performs as stated.
Thank you for your support of our commitment to developing the highest quality tools and technology for preserving the health, security, and integrity of personal computing.
