Apex Flow Shield

Every feature, and whether it is really built

We label every feature with what is actually true today.

Works on your phone alone Built; needs a server or account you provide Not built yet

Encrypted vault

Works on your phone alone

Passwords, notes and 2FA codes, locked with a key made from your passphrase (Argon2id and XChaCha20-Poly1305). Optional decoy passphrase, growing lockouts, erase after too many wrong tries, panic erase.

Device check

Works on your phone alone

Screen lock, root or jailbreak warning signs, and how old the system software is. Unknown checks are shown as unknown, never as passed.

Scam link checker

Works on your phone alone

Spots look-alike brand names, the "@" trick, raw addresses and link shorteners. It never opens the link and never says a link is safe.

Leaked-password check

Works on your phone alone

Checks passwords against the public Have I Been Pwned list. Only the first 5 characters of a scrambled fingerprint leave your phone.

"Prove it" tests

Works on your phone alone

Runs the encryption against published test values and real round trips on your own device, so you do not have to take our word.

Private chat

Built; needs a server or account you provide

End-to-end encrypted (MLS, with a hybrid scheme designed to resist future quantum computers). Safety numbers, key-change alarm, disappearing messages, burn a chat on both phones. Needs a relay server.

Voice calls

Built; needs a server or account you provide

End-to-end encrypted. Call setup travels inside the encrypted chat so nobody can swap the call's certificate. Proven on desktop; not yet on phones.

Protected DNS

Built; needs a server or account you provide

Sends website lookups over HTTPS to a server that refuses known tracker and malware names, for every app. Needs a DNS server.

VPN file builder

Built; needs a server or account you provide

Makes the keys and config file for the free WireGuard app, on your phone. Needs a VPN server.

Burner numbers

Built; needs a server or account you provide

Rent a number from your own Telnyx account and read its texts here. Shows the exact cost first and will not buy without a monthly cap.

Android app scan

Not built yet

Scanning installed apps for malware on Android.

None of the features that need a server has been tried on a real phone yet. Voice calls are proven on desktop only.
