Common questions about licensing and pricing.
Yes, it is genuinely perpetual. The version you license never stops working. There is no kill-switch, no online activation server that can be revoked, and no time-limited DRM. Even if we ever stopped operating, your installed software would keep running exactly as it does today.
Every license includes one year of free upgrades from the purchase date, so you receive all new versions and features released during that year. After the year you keep using your version for as long as you like, and renewing maintenance to continue receiving updates is entirely optional.
Yes. Deactivate on the old machine, then activate on the new one. If you change machines often, or need to run it for the same single user on more than one device, contact us and we will help.
Yes, there is a full-feature free trial with no credit card required, so you can confirm the software fits before you pay. Because you can evaluate first, purchases are generally final once your license key is issued; if something is genuinely wrong, contact us and we will make it right.
No. All modeling, calculation, and report generation happen entirely on your machine. The software does not send your decision data, probabilities, or models to any cloud service, which keeps your work audit-ready and procurement-friendly.
The software runs on Windows today, and native macOS support is on the way, so you will be able to run it on both.
Yes. For procurement we provide formal quotes on company letterhead, vendor questionnaires, tax forms, and net-30 invoicing. Volume pricing applies as you add users beyond the first, and unlimited-seat site licenses are available. Contact us with your requirements and we will prepare exactly what your purchasing team needs.
