Bulbul
A vault with no master password — every code opens a different space
Bulbul is a private file vault with no master password. There is no separate "unlock screen" — what you type IS the vault. 1234, 0000, 9876 — any digits instantly open a fresh space, with no "main" or "decoy" hierarchy.
Key Features
The Code IS the Vault
No unlock screen. The code you type is the destination, and each code opens a completely different space. Like Schrödinger's cat, no one can tell whether a vault exists until you type the right code.
Everything Inside the Vault
Files, a Markdown editor, a camera that saves photos and videos straight into the active vault instead of your camera roll, and a built-in browser whose history and bookmarks never leak between vaults — all in one place.
Share Extension
Send files into a vault directly from other apps via the system share sheet. The extension shares App Group and Keychain access group with the main app for the same security context.
Escape Action and Biometrics
Optional Face ID / Touch ID gates each vault, and Escape Action snaps a vault closed in response to a trigger such as a shake. iCloud sync is opt-in per vault.
System Requirements
iOS 26+
