Sharing an apk on the internet

Hello, Vuforia Team! I'm a graduate student and I'm using the Vuforia Engine to develop an application prototype as part of my research solution. I've developed the prototype in Unity using the Vuforia SDK version 9.8.5. The prototype uses some of the Ground Plane features from the Vuforia Core Samples available on the Unity Asset Store. Recently, after Vuforia was updated to version 10, I added a basic license key to my Unity project and built an apk file. I would like to clarify the following questions. (1) Can I share, for free, a link to the apk file in my master's dissertation? (2) Can I share, for free, a link to the apk file on social networks? (3) Can I share, for free, a link to the apk file in portfolios? (4) Can I share, for free, a link to the apk file through other electronic means? (5) Can I share, for free, a link to the apk file in academic works so that other people can contribute to the research? I do not intend to commercialize the prototype. Kind regards, Glice Pires
