Graphical Analysis Pro and Vernier Video Analysis do not track individual users or collect any personally identifiable info.

Both applications are distributed by subscriptions that have tiered pricing depending on school or department size.

We trust schools to give us an estimate of the school size at the time of purchase. We may look up how big a school is online to make sure estimates of school size are correct. We do not know who the users are at all, other than that they are using a particular school’s license. We only know that the activation code for a given school is being used by a device. No information is captured that can track or identify the device or user.
