๐ Verification
Encrypted, and you can prove it
Direct messages are end-to-end encrypted by default, and so are private rooms and their files once encryption is on. Angaara uses Matrix's Olm and Megolm through the Rust crypto engine, built on the Double Ratchet, the same design Signal uses. Compare emojis or scan a QR code to prove there's nobody in the middle.
invoice_march.pdf.lnkDangerous
- Fake file type. A Windows shortcut named to look like a PDF.
- Hidden command. Runs PowerShell with its window hidden.
- Decoded payload. Base64 that downloads and runs a file.
- Download link. A site registered 3 days ago. Check link
๐ File & Link Check
Check it before you open it
Got a file from someone you don't know? File Check takes it apart on your device without running it: fake file types, shortcuts and scripts, macros and remote templates, packed Windows programs, and ReversingLabs' open malware rules. Link Check follows every redirect in a sandbox and flags days-old sites and fake sign-in pages.

๐ถ๏ธ Privacy
We keep almost nothing
Your messages never pass through us. They go straight between the app and your Matrix homeserver. Turn on private mode and the app stops contacting Angaara's own server entirely. Everything we do store is listed, line by line, on our data page.
Where should your account live?
matrix.orgFree public server
mozilla.orgRun by Mozilla
chat.yourfriends.orgYour own server
Self-hosted
โ Can still talk to people on every other Matrix server
๐ Decentralised
You choose who runs the server
Angaara runs on Matrix, an open, decentralised network. Use a public homeserver, or run your own so your data lives on hardware you control. Teams on different servers can still talk to each other, and the app itself is open source, so you can audit it or host your own copy.
๐๏ธ Voice & Screen Share
Private briefings, face to face
Voice channels are end-to-end encrypted, with AES-256 keys where every device supports it. Walk your team through a document by sharing your screen in up to 1440p at 60 FPS, with everyone lined up underneath.
What encryption can't hide
Know a tool's limits before you trust it with anything that matters. Here's what stays visible, no matter which app you use on Matrix.
๐๏ธMetadata
Your homeserver can see who's in a room, when messages are sent and by whom, and room names, topics and profiles. It can't read the messages.
๐Public rooms
Rooms anyone can join aren't encrypted, because anyone can read them anyway. Keep sensitive talk in DMs and private rooms.
๐Unverified devices
Until you verify someone, you're trusting your homeserver to hand you their real keys. Verify the people who matter.
๐ฑYour device
Encryption can't help if a device is already compromised. Keep devices updated and sign out of ones you don't use.
Facing a serious threat? No app is enough on its own. Pair it with a proper threat model, and talk to a digital security specialist.
