Powered by Google’s Nano Banana models — the same image AI behind Google AI Studio. Cinematic compositions, vivid colors, no watermarks.

AES-256-CBC Encryption
Your API key is encrypted using AES-256-CBC — the same standard used by banks — before being saved to your WordPress database.
Per-Site Encryption Salt
A unique random salt is generated for each WordPress installation. Even if two sites use the same key, the encrypted values will differ.
Nonce-Protected AJAX
Every admin action is verified with a WordPress nonce token, protecting against CSRF attacks and unauthorized requests.
