EpsiVault: Private Vault

EpsiVault is a private vault for your photos, videos, and documents —
encrypted on your device with post-quantum cryptography, and opened only by
your fingerprint or face.

WHY EPSIVAULT

Most "secure folder" apps protect a password, not your files. EpsiVault
encrypts every file you import with strong, modern cryptography designed to
resist attack even from future quantum computers — before it's ever written
to storage. The key that unlocks your vault lives in your device's secure
hardware (Secure Enclave / Android Keystore) and is only released after a
successful biometric check. Your fingerprint or face scan itself never
leaves your device's biometric hardware — EpsiVault never sees it, stores it,
or sends it anywhere.

HOW IT WORKS

• Import photos, videos, or documents from your gallery or files.
• Each file is sorted into a category (Photos, Documents, Financial,
Medical, Videos, Other) and encrypted individually.
• Unlock the vault with your fingerprint, face, or a PIN (offered only on
devices without biometric hardware).
• Browse and view your files — they're decrypted only for the moment
you're viewing them, never left sitting unencrypted on your device.
• Optionally send a file directly to another one of your own devices over
your local Wi-Fi network — never through the internet or a server.

PRIVATE BY DESIGN

• No account, no sign-in, no ads, no analytics or trackers of any kind.
• Nothing about you or your files is ever uploaded anywhere. There is no
server — EpsiVault has nothing to send data to even if it wanted to.
• No cloud backup or cloud sync. Your vault's key exists only on your
device — that's what makes it yours alone.

IMPORTANT: BECAUSE THERE'S NO CLOUD BACKUP

If you lose this device, reset it, or uninstall EpsiVault, the files inside
your vault cannot be recovered — there is no backup key anywhere, including
with us. EpsiVault will warn you about this the first time you use it. This
is a deliberate trade-off: the only way to guarantee nothing about your
