Silverstack is offered as a yearly subscription and as a temporary license especially intended for single projects.
Silverstack yearly subscription
The yearly licenses are valid for one year from the date of the purchase. Their renewal can be canceled at any time. For further questions on our yearly licenses or on billing, see this article.
If you later decide that you would like to upgrade your Silverstack yearly license to a Silverstack XT yearly license, please contact us at firstname.lastname@example.org.
You can upgrade to Silverstack Lab via the automatic upgrade form.
Silverstack temporary licenses
We also offer Silverstack, Silverstack XT and Silverstack Lab as temporary licenses which are especially intended for single projects. These licenses are valid for the chosen time period (14 days, 1 month, 2 months). The license period starts on activation in the software, which can be later than the date of purchase. These licenses also expire after the chosen time period with no automatic renewal available.
