One of DEADFACE's junior developers has shared a new Android app that they wrote to store secure notes. We managed to get our hands on it, but when we run it, the secure note requires a password that we just can't figure out. Can you use your skills to tear the app apart and find the flag?

Submit the flag as: `deadface{flag_text}`.
