Yes. In fact, there are several different options.
ZotPad participates in Apple Volume Purchase Program for Education, which gives 50% discount to purchases of 20 or more licenses. All licenses purchased through the program receive the same support from ZotPad as the licenses purchased outside the program.
Institutions that participate in App Store Volume Purchase Program for Business can purchase a campus license. With this option, the institution receives a custom B2B build of ZotPad, which can be downloaded for free in the App Store. Pricing is negotiated case-by-case. Please contact firstname.lastname@example.org for details.
Institutions that participate in iOS Developer Enterprise Program can deploy ZotPad through In-house Distribution. This option can be implemented by downloading the ZotPad source code, licensed under GPL version 3, and compiling it in-house for distribution. ZotPad does not provide end-user support for in-house builds of ZotPad and the institution is responsible for testing and rolling out updates. However, producing in-house builds and user support can be purchased as a service from ZotPad. Please contact email@example.com for details.
In the future there will be a free student version of ZotPad and this may satisfy the needs of some institutions. Check this page for up to date information on future plans.
