## Overview

The application protects access through its calculator-style vault passcode, but the stored data is not bound to that authentication boundary. A local actor who can access shared external storage, such as through an authorized non-root ADB shell or another local file-reading context with suitable storage access, can copy the SQLite database and media files directly without entering the vault passcode.

## Remediation
