End-to-end by default
Messages and sealed notes stay ciphertext on our servers. We cannot read them.
Security & privacy
Built like a briefing room, not a social network.
Hard edges. Thin trust surface. Your circle stays yours.
Invite-only access
No open registry. Membership is granted, not scraped from a signup form.
Minimal metadata
Ops-grade posture: less to leak, less to subpoena, less to habitually collect.
Zero ads
No attention market
No public profile
Private circle only
Device lock
Passcode after first unlock
The model
Wizper is an invite-only web app. A cell number is the identity. Email is collected once, at setup. A six-digit passcode locks the session after first unlock. Chat is end-to-end encrypted. Notes are sealed on the device and stored as ciphertext. This marketing site is not the messenger. A request does not open an account.
Invited members enter at wizper.pro.
Calls
Voice and video stay in the app. Direct media uses WebRTC. Group calls use a LiveKit selective forwarding unit, so there is no public room link. A forwarding unit is a server in the media path. Group video is not the same guarantee as sealed chat.
What we will not claim
- No third-party audit badge is displayed here.
- No jurisdiction shield. Infrastructure is hosted in the United States.
- No promise that every network log is empty. Minimized is the word.
- No card checkout, app store, or SMS enrollment on this site.
Internal scale
These figures are our own review, not a certificate. Invite-only messenger privacy sits about 9.75–9.8 on our scale, near Signal at about 9.8–9.9 for a private circle. Sealed Notes sit about 9.4–9.6, which we rank first or second among note apps we compared.
Only $98.00 per month. The request does not charge you.
