Cooperation without exposure
Refusing to unlock can mean detention or a refused entry. Sealby removes the dilemma: comply, open an innocuous vault, and the rest stays invisible and unprovable.
Use case
Cross the border. Keep your life private.
Device searches at borders are legal in many countries and you can be required to unlock. Sealby is built for exactly this moment: open a harmless vault and cooperate fully — nothing can prove another vault exists.
How do I protect my phone’s data at a border crossing?
Travel light: remove what you don’t need, and keep what you do need in a deniable encrypted vault. With Sealby, unlocking your phone and even opening a vault reveals only that vault — the number of vaults is forensically undetectable, so there is nothing further to demand.
No count, no list, no trace
There is no vault registry to find. Forensic tools see the same thing whether you have one vault or ten — random, unreadable data.
Travel empty, restore later
With Premium sync you can even travel with a clean install and restore your vault from its encrypted blob when you arrive, using its recovery phrase.
Common questions
Can border agents tell I’m using a hidden-vault app?
They can see the Sealby app itself, and you can open a real, innocent vault for them. What they cannot do is prove any other vault exists — there is no count, no index, and unrevealed vaults are indistinguishable from random data.
Is it legal to use encryption when travelling?
In most countries, yes — encryption is standard on every modern phone. Rules on unlocking differ by country, which is exactly why Sealby is designed so that complying with an unlock request doesn’t expose everything you own. This isn’t legal advice; check the rules for your route.
