Sekuvo is a fully offline password vault for Android. It does not request the
Internet permission, so your data is technically incapable of leaving the
device. No account, no cloud, no sync, no telemetry.

WHAT IT STORES
• Accounts and passwords, with the site or app they belong to
• Everyday details: name, phone, email, address
• Cards: number, expiry, CVV, IBAN
• Secure notes, including scripts, keys, recovery codes and config files
• Unlimited custom fields on any entry — all encrypted

ENCRYPTION
Every sensitive field is sealed with AES-256-GCM. The key is derived from your
master password with PBKDF2-HMAC-SHA256 at 600,000 rounds, on your phone, every
time you unlock. There is no recovery backdoor: if you forget the master
password, the data is gone. That is the design.

WITHOUT THE CLIPBOARD
The clipboard is where secrets get stolen, so Sekuvo delivers values straight
to their destination in three ways:
• Android autofill — sign-in and card forms offer your entries directly
• Sekuvo Keyboard — type a stored secret into any field, in any app
• Bluetooth — your phone becomes a keyboard and types into your computer, with
nothing installed on the computer (Windows, macOS, Linux)
Copying still works. The clipboard clears after 45 seconds while Sekuvo is
on screen, or the moment you return to it: Android does not let an app clear
the clipboard from the background, so a copied value stays there until you
come back.

LOCKING
The vault locks the moment the screen it is on goes dark — including folding a
foldable. Optional fingerprint or face unlock is a convenience layer; the
master password always works.

BACKUPS YOU CONTROL
System backup is deliberately disabled. Your vault leaves the phone exactly one
way: an encrypted .vaultbak file you create and place wherever you choose. File
plus backup password restores everything on any phone, even after a factory
reset. Secrets can also be brought over from a computer as an encrypted
envelope, pasted as text or scanned as QR codes.

USAGE LOG
Sekuvo records which field of which entry went where and when — to the
clipboard, to a computer, or into an app. Values are never written to the log.
When a computer is compromised, this answers what you need to change.

HARDENING
Screenshots and app-switcher previews blocked, clipboard auto-clear, PIN
brute-force throttling, size limits that keep a vault from becoming
unreadable.

OPEN SOURCE
