Nothing to find, nothing to explain
Open a harmless everyday vault if you’re ever made to. The existence of any other vault is undetectable — there is no list, no count, no trace.
Use case
Privacy that holds when someone checks your phone.
If someone in your life goes through your phone, an ordinary “hidden” folder is a risk — and even a visible security app can escalate things. Sealby is different: what you keep in a hidden vault cannot be found, and cannot be proven to exist.
How can I keep documents safe if someone checks my phone?
Use a vault that is deniable, not just locked. In Sealby, a hidden vault is indistinguishable from nothing: someone scrolling your phone finds an innocuous app you can open to a harmless vault, while photos, records and plans stay in one no one can prove exists.
A place for what matters
Photos, screenshots, medical records, copies of IDs, important numbers, a plan — kept together, encrypted, and available the moment you need them.
A last-resort duress PIN
If you choose, set a PIN that irreversibly wipes hidden vaults when entered — so being forced to unlock destroys the evidence of the vault instead of revealing it.
If you are in immediate danger, contact local emergency services. Technology is one layer of safety — local support organisations can help with the rest.
Common questions
What if I’m forced to open the app?
Open your everyday vault — it is a real vault with real, innocuous content. Nothing in the app shows other vaults exist, and forensic inspection can’t prove otherwise. If you set a duress PIN, entering it silently wipes the hidden vaults instead.
Will the app itself draw attention?
Sealby looks like an ordinary utility, and opening it to a normal vault is a complete, consistent answer. There are no “decoy mode” toggles or second password prompts visible anywhere.
