BlackVault Chat

BlackVault is a private, invitation-only messenger for teams and organisations that need confidentiality. Accounts are created with an invitation code from your organisation's administrator. No phone number or email address is needed — you choose a username. END-TO-END ENCRYPTED • Messages, photos, videos, documents and voice notes are encrypted on your phone and can only be opened by the people in the chat. • Voice and video calls, including group calls, are encrypted from phone to phone and ring like normal iPhone calls. • The server only relays encrypted data. There is no cloud backup: chats stay on the participants' phones. YOU DECIDE WHO CAN REACH YOU • Chat requests: people who add you by username must be accepted before they can message or call you. • Colleagues from your organisation's directory can connect directly. • Block, Block & report, and a Blocked contacts list in Settings. PRIVATE BY DESIGN • Locked with your BlackVault PIN or Face ID. • Screenshots of chats and opened files come out black; Settings stay normal. • Screen-recording privacy cover and hidden app-switcher previews. • Disappearing messages, view-once and view-twice photos and videos. • Delete for everyone without a trace, and clear chats on one or both sides. • Security status screen and contact key verification. BUILT FOR WORK • Group chats with admin settings (who can send messages, edit group info and add members) and automatic admin handover. • Group voice and video calls; add people to a call. • Open PDF, Word, Excel and PowerPoint files inside the app — files stay inside BlackVault. • Forward messages with control over where they went. • Search messages, per-chat notification tones, read receipts on or off. ACCOUNT CONTROL • Delete your account permanently from Settings. BlackVault requires an invitation code from your organisation.
