Billed usage in Pencil Spaces is calculated in
participant-minutes, starting only when there are
two or more participants in a Space. If a teacher or participant is alone in the Space, no usage is billed. Additionally, you are not charged for using multiple devices with the same account—for example, joining the Space on a desktop while annotating over PDF in the Space on an iPad. However, you cannot join the same call on two devices at the same time using the same account. You can learn more about our billing methodology
here.
If you are using on certain Enterprise plans, we may bill you differently. Please contact Support to learn more about how billing is calculated for your institution.
