Vernier Video Analysis and Graphical Analysis Pro are distributed on a site license basis. A school with a site license may use the app on any computer or device under the school’s control. In addition, the access URL (for Vernier Video Analysis) or code (for Graphical Analysis Pro) may be shared with faculty, staff, and students so that the app can be used on their personal devices.
Most trial periods last for 30 days. In North America, purchased licenses run through June the year following the purchase. For example, a license purchased in January 2020 is active through June 2021. A license purchased in October 2020 is also active through June 2021.
Continuous use of Vernier Video Analysis or Graphical Analysis Pro over multiple years thus requires a new purchase every year.
A device must have internet access to activate these apps, but it does not have to be continuously online to use the app. As long as the app has been used while online in the previous two weeks, it can be used offline.
The About dialog of the app shows the name of the school holding the license and the license expiration date. Schools and user may not distribute the access URL or code outside of the school system.
