One file. Unlimited vaults. Every password opens different data. Under pressure? Give any password — they'll never know your real secrets exist. What they find isn't what you hide.
Features
Not just encryption — a completely new approach to hiding what matters.
One storage file, unlimited passwords. Each password reveals completely different data. There's no way to prove other passwords exist.
Every password reveals a different truth. Hand over a decoy — your real secrets remain in vaults they can't prove exist.
Drop any files onto the MAGIC disk — a photo, a document, anything or just create few folders. Those exact files and folders with names and content become your key. No password to remember, just have the right files.
Your encrypted storage mounts as a real APFS/ExFAT disk. Use Finder, any app, drag & drop — just like a USB drive.
TOTP secrets never stay in memory. Decrypt → generate code → destroy instantly. The most secure way to use 2FA on a computer.
Your encrypted file looks like random data. No headers, no signatures at all. Forensic tools can't even identify it as encrypted or encrypted with Sundy.
How It Works
Traditional password or revolutionary MAGIC disk.
Enter any password. Each unique password creates its own isolated vault. Use different passwords for different sensitivity levels.
Sundy creates a special MAGIC volume. Copy specific files to it — their content becomes your password through hashing. Same files = same vault.
Your vault appears as a real disk in Finder. Save files, open documents, use any app. Everything encrypted on-the-fly.
Eject the disk, close Sundy, or remove MAGIC disk — your vault locks instantly. No traces left behind.
Use Cases
Sundy shines where regular encryption fails.
Authorities demand your password? Give them one — they'll see innocent files. Your real data stays hidden in a password they'll never ask about.
Store wallet seeds in one vault, trading credentials in another. Even if compromised, attackers only get one piece of the puzzle.
Sensitive R&D, trade secrets, strategic plans — each in separate password-protected vaults. Insider threats see only what you allow.
Protect your sources. Store evidence in hidden vaults. Under coercion, reveal a decoy. Your critical data remains invisible.
Patient data, case files, privileged information. MAGIC disk access means no password shoulder-surfing in the office.
Financial records, estate plans, personal matters. Different passwords for accountant, lawyer, and truly private data.
Security
The vault they can't prove exists. Real privacy leaves no trace.
Your Sundy file contains no signatures, no headers, no magic bytes, no metadata — nothing that identifies it as encrypted or created by Sundy. To any forensic tool, file analyzer, or expert — it's indistinguishable from random data.
No one can prove it's a container. No one can prove you're hiding anything. No one can prove Sundy was ever installed. It's just a file filled with noise. Maybe it's encrypted. Maybe it's corrupted data. Maybe it's nothing.
Same encryption as classified government data
Zero identifiable patterns or markers
Can't prove how many vaults exist
Keys decrypted, used, destroyed instantly
No cloud, no servers, no leaks
Stop relying on "hidden folders" and hope. Get real protection.
