DELKA LINK UP is a fast, beautiful desktop messenger with true end-to-end encryption. Your messages, files and voice notes belong to you — and only you.
Windows 10 & 11 · v0.1.0 · 1.6 MB · invite code required to register
Messages are encrypted on your device with modern ratcheted encryption. The relay stores only opaque ciphertext — it can never read your chats.
Send files up to 2 GB. They are encrypted, delivered once, then deleted everywhere — no copies linger on the server.
Online status is hidden by default. Nobody can see when you’re online or offline unless you choose to share it with them.
Invite-only registration. No ads, no link previews, no analytics. Your metadata footprint is kept to the absolute minimum.
