Wisp
The private messenger. Every message and every call is end-to-end encrypted — we can't read them, and neither can anyone else.
Wisp uses the Signal protocol, the gold standard of messaging encryption, with post-quantum key agreement. Your conversation history lives only on your device. No ads, no trackers, no selling your data — privacy is the product, not you.
- • End-to-end encrypted messages, voice and video calls
- • Private groups — even our servers can't see who is in them
- • Disappearing messages, view-once media, screen security
- • Encrypted backups you alone hold the key to
Truly end-to-end encrypted
Every message, call, photo, and file is encrypted on your device with the Signal protocol before it leaves — including a post-quantum key exchange. The keys never touch our servers, so nobody in the middle, us included, can read a word.
Private by design
Sealed sender hides who sent a message even from our servers. Your name and photo are encrypted so only your contacts can see them. Your message history exists only on your phone — we keep no copy and have nothing to hand over.
You stay in control
Disappearing messages, view-once media, remote delete, message requests from strangers, blocking and reporting, app screen lock. Delete your account at any time, straight from the app — it removes your data from our servers immediately.
Calls that stay private
Voice and video calls are end-to-end encrypted with the same technology that protects your messages — and they ring even when the app is closed.
Groups without surveillance
Group names, photos, and member lists are encrypted end-to-end. Our servers store an opaque blob — they cannot tell who belongs to which group.
Everything a messenger needs
Reactions, replies, typing indicators, stickers, GIFs, link previews, stories, starred and pinned chats — full-featured messaging, without the tracking that usually pays for it.
