SP SecurePrefs is a group of classes focused on securing PlayerPref data on the user's machine/mobile using encryption and also to integrate a timer that you can use to give the user to activate certain functionality.
This script will Encrypt / Decrypt your PlayerPrefs. It is very simple to use as same as how you use PlayerPrefs.
* Encrypt User Data (PlayerPrefs) using encryption keys. 
* Manage User Data in 1 script that is active across All Scenes. 
* Functional code of knowing if this is the user’s first time or not for initialising Tutorials or Intro Scenes etc... 
* Integrated encrypted timer so you can call certain functionality every X timescale (hh:mm:ss). 
* Full working example of all the above in a Scene with fully commented code.
