Business idea:

Create a VPN type app thay runs in the background of your phone to encrypt and spoof companies and governments that are looking at your data.

Spoof GPS location

Encrypt all data in and out of your phone to prevent people from seeing your texts, listening to your calls, tracking your internet searches ect.
