A day with FuaFlow Vault
The day you get the keys to your new place: papers, photos, messages and the ride home — all under lock and key.

09:05
Your papers, under lock and key
You pick the photos of the lease and your ID, and FuaFlow Vault packs them into an encrypted vault right there on your phone: with a password, or sealed for specific people. With “View contents” you see the thumbnails instantly and pull out a single file when you need it.

You send it sealed
Your roommate asks for the lease. You seal it with her contact key and send it however you like — AirDrop, Messages, email. The vault travels encrypted and only she can open it; we can’t either.
-
11:32
You text her, even when she’s away
The app’s chat is end-to-end encrypted. On the same Wi-Fi, the message goes straight from phone to phone, no internet needed; when she’s away, it waits in a blind mailbox that only sees sealed envelopes and reaches her when she opens the app. The envelope is deleted once delivered.

Photos that can be verified
When you get the place, you take photos of how it looks. The verified camera signs them on your phone with the time and place, and, if your contacts agreed to be your witnesses, their phones with the app open on the same Wi-Fi sign it too. Later, anyone with FuaFlow Vault can check they weren’t edited.

“Back in 30 min”
On your way home, you start a check-in and share your live location with your circle until 23:30. If you don’t confirm in time, a notification reminds you and, when you open the app, your SOS goes off.
-
23:16
Home safe
You tap “I’m OK” and the check-in closes. Tomorrow, what’s yours is still under lock and key.
What’s inside
Vault, camera, chat and circle in one app, with no account.
Encrypted vaults
Photos, videos and documents in a .pvault file, encrypted with AES-256-GCM on your phone.
For whoever you choose
For you (by default, with your identity), with a password, or sealed with your contacts’ keys: only they can open it.
Verified camera
Photos and videos signed on your phone with the time and place.
Witnesses
Contacts who agree to be your witnesses sign, with their location, that they were there when you took it. The first time, the app asks them.
Private chat
End-to-end encrypted: direct on the same Wi-Fi or, when you’re apart, through a blind mailbox. Photos and files only go direct, on the same Wi-Fi.
Send over Wi-Fi
A vault from phone to phone, no internet needed; if it drops, you resume where it left off.
Your identity
A key born on your phone; share it by QR or link so people can add you.
Lock
If you want, the app asks for Face ID or your iPhone’s passcode; your system does the check.
Circle & SOS
Emergency contacts, SOS, check-in and temporary location. Free, always.
Your circle and SOS, one tap away.
Free, always: with or without Pro. SOS and alerts use no server: they reach your people through Messages and phones running the app on your same Wi-Fi. Live location, if your contact is away, travels sealed through the relay mailbox.
It doesn’t replace 911: if you’re in danger, call emergency services too.
- SOS: one tap alerts phones running FuaFlow Vault on your same Wi-Fi and gets the text with your location ready for your circle. iOS doesn’t let an app send texts on its own: you tap send.
- Check-in: “back in 30 min”. If you don’t confirm in time, a notification reminds you and, when you open the app, your SOS goes off.
- Live location for your circle for 15 min, 1 h or 24 h: encrypted to your FuaFlow Vault contacts (if they’re away, it travels sealed through the relay mailbox, which can’t read it), or by text message.
- Public alert to phones running the app on your same Wi-Fi, for a lost pet or child.
We can’t open what’s yours.
FuaFlow Vault has no accounts, no trackers and no ads. Your vaults and your messages are encrypted on your phone; the little that goes through our server travels sealed and is deleted once delivered.
- Your vaults are encrypted with AES-256-GCM on your phone, with your identity, with your password or with the key of whoever receives them.
- The relay server’s mailbox only keeps sealed envelopes: it doesn’t know who sends them and deletes them on delivery, after 7 days at most. You can turn it off.
- Your identity is a key pair created on your phone and kept in the system Keychain. Back it up in Profile → “Back up identity” to open your “For you” vaults on another phone.
- If you forget a vault’s password, nobody can recover it — including us. That’s what makes it safe.
Price
14 days free for first-time subscribers, then a monthly subscription — or a single payment, forever — at your country’s price. The 14 days are the start of the monthly plan: cancel anytime from your Apple account.
Pro is for creating and sending: new vaults, verified photos and videos, messages, transfers and linking devices. Without Pro the app becomes read-only, never locked: you open, view, extract, share and verify what you have and whatever people send you. SOS and your circle always work, with or without Pro.
