There is a growing emphasis among users on safeguarding personal privacy and authorization for applications. To address this, Security and Privacy Updates (SPU) are employed to bolster app security, alleviate user apprehensions regarding security, and encourage users to share data and permissions with greater confidence.

We will investigate this process through a set of online experiments.
