What is AES-256 in simple terms?
AES-256 is a widely used standard for encrypting digital data.
Without going into mathematics, you can think of it as a very strong digital safe. A normal file can be read directly. Once encrypted, its contents are transformed into protected data that cannot be meaningfully read without the correct cryptographic key.
To return the protected data to its original readable form, the correct key is required.
In PrivateProScanner, that process happens automatically. You do not have to create long keys, store technical codes, or perform a manual encryption routine every time you open a document.
From your perspective, the workflow remains normal: scan a file, save it, and open it later. The encryption works in the background.
AES-256 is important because it protects the stored data itself, not just the screen you see when entering the app.
That is different from a PIN or Face ID. A PIN and biometrics control access. Encryption protects the form in which the files are stored.
PrivateProScanner uses AES-256 as part of its protection model while keeping the user experience simple.
