Quill Chat

Private encrypted messenger

Free · Designed for iPad. Not verified for macOS.

Quill is a private, end-to-end encrypted messenger built for business teams that take confidentiality seriously. Every message, photo, file, voice note and call is encrypted on your device with the Signal Protocol — the same cryptography trusted by security professionals worldwide. Our servers relay only ciphertext: we cannot read your conversations, and neither can anyone else. PRIVATE BY DESIGN - End-to-end encryption for every conversation (Signal Protocol: X3DH + Double Ratchet with perfect forward secrecy) - Zero-knowledge server — no message content is ever stored server-side; undelivered messages wait as encrypted blobs and are purged on delivery - Encrypted voice calls secured with DTLS-SRTP - No ads, no trackers, no analytics SDKs BUILT FOR TEAMS - Invite-only: accounts are created by your organisation's administrator, so you always know who can reach you — there is no public sign-up - Private group chats with member verification and admin-only posting - Share photos, files and voice messages — all encrypted - Fast, familiar chat experience with a clean, modern interface SECURITY THAT GOES FURTHER - Passcode or Face ID / Touch ID lock before the app opens, with automatic locking after inactivity - Screen-capture protection to keep conversations private - Disappearing messages, one-time view media, and a full ephemeral mode that keeps no history at all - Local data protected with encrypted storage (SQLCipher) - Privacy-respecting push notifications that never contain message content WHO IS QUILL FOR? Quill is designed for businesses, teams and professional groups that need genuinely confidential communication — legal, finance, healthcare, management, or any team whose conversations shouldn't live on someone else's servers in plain text. GETTING STARTED Quill is invite-only. Your organisation's administrator creates your account and gives you your credentials. If your organisation doesn't use Quill yet, visit https://quill.clareinfotech.com or contact support@clareinfotech.com to get set up.

Workspaces for teams: businesses can now sign up for their own Quill workspace, invite members by e-mail, and manage plans and billing from the admin panel. If your admin gave you a temporary password, the app now asks you to choose your own after signing in. Plus the call and stability fixes from recent updates.
