That's really not actually how open source works and how it influences privacy and security. It is not easy to determine what apps do even with full access to the sources, let alone if they are private and secure.

Sandboxing and permissions are certainly relevant to open source apps. They are very relevant within the OS too. Sandboxing and the principle of least privilege is used throughout the OS and is immensely important. Open source doesn't change this.
