Decoy vaultsDeny everything.
Show them a vault.Not the vault.
In Sigilock, every sigil opens a different vault, and nothing on the phone lists them. So when someone insists on seeing what’s inside, you can open one that holds nothing that matters.

How it works
- 01
Draw a new sigil
On the lock screen, draw a pattern you haven’t used. Sigilock offers to seal a new vault behind it.
- 02
Make it believable
Give it a name, and add a few ordinary photos so the decoy looks lived in.
- 03
Open the right one
Draw the decoy when you have to, and your real sigil when you’re alone.
Why a vault app needs a decoy
A vault app on your home screen invites a question: what’s in there? A password can protect the contents, but it can’t make the question go away, and refusing to answer often says more than the photos would.
A decoy lets you answer. Draw a second sigil and a real, working vault opens, with real photos in it, just not the ones that matter. The person looking sees exactly what they expected to see.
Built for plausible deniability
A decoy only works if nothing gives it away. Sigilock has no list of vaults, no count, no switcher between them and no setting that mentions the others. Each vault is opened only by its own sigil, and from inside one there is no trace of the rest.
On disk, every vault is just encrypted data. Someone with full access to the phone’s files could see that several encrypted vault folders exist, but not which sigil opens which, which one is the decoy, or what any of them contain.
Making a decoy convincing
An empty vault is suspicious. Give the decoy a believable name and fill it with things people really hide: a few screenshots, ordinary documents, photos you would rather not share but wouldn’t mind being seen. Open it now and then, so it doesn’t look untouched.
As many as you need
Personal, work, a decoy or two. One sigil each.
Nothing to find
No vault list, no counter and no setting that gives the others away.
A real vault
A decoy isn’t a fake screen. It is a full, encrypted vault and behaves exactly like one.
A partner, a parent or an official asks you to open your photo vault. You draw the decoy sigil, they see a few holiday photos, and the conversation ends there.
Decoy vaults, answered.
More questions? See Support or read how the security design fits together.
How many vaults can I have?
As many as you need. Any new sigil can open its own vault.
Can someone tell how many vaults I have?
Not from the app. Someone with full access to the phone’s files could count the encrypted vault folders, but not tell which sigil opens which, or what is inside.
Is a decoy vault different from a normal vault?
No. Every vault is a full, encrypted vault. The only thing that makes one a decoy is what you choose to keep in it.
How do I switch from one vault to another?
Lock the vault, then draw the other vault’s sigil. There is deliberately no menu that lists or switches between vaults.
Can I rename or delete a vault?
Yes. Each vault has its own settings, where you can rename it or delete it. Deleting a vault erases its contents permanently.
Does a decoy cost extra?
No. Every plan includes as many vaults as you need, decoys included.
Do decoy vaults have their own recovery phrase?
Yes. Every vault, decoy or not, gets its own 12-word phrase when you create it.
