💡 HOW IT WORKS

1. Create a passphrase only you know
2. Store your information securely
3. Access when you need — works offline

Your passphrase is never stored. It exists only in your memory. This PROVES there is no copy anywhere.

━━━━━━━━━━━━━━━━━━━━━━

⚠️ IMPORTANT

If you forget your passphrase, you WILL LOSE access to your data. There is no recovery. This is by design — it ensures nobody but you can access your information.
