🔒 Privacy & Security

• 100% Client-Side: All operations run in your browser. No data is sent to any server.
• No Dependencies: Pure HTML, CSS, and JavaScript — no npm packages or frameworks.
• HIBP Integration: Password breach checking uses the k-Anonymity model (only a partial hash prefix is sent).
