Fully encrypted chat — even with people outside Private.Ki
Open a private channel with anyone by sending them a secure link. They can reply instantly without signing up, while encryption keeps the conversation fully private.
Privacy isn’t a feature. It’s the foundation.
Private.Ki Chat encrypts every message, attachment, and metadata element directly on your device. People you invite don’t need an account, and no identifiable information or logs are ever exposed — security is embedded at every layer.
How it works
Start a private, end-to-end encrypted chat with anyone — even if they don’t have a Private.Ki account.
Send an invite
Enter your contact’s email address and send a secure chat invite. No account or password is required on their side in advance.
They open the secure link
Your contact clicks the link from the email and chooses a username. No sign-up is required.
The chat opens automatically
As soon as they join, a private and fully encrypted chat between the two of you is created.
All messages and metadata are end-to-end encrypted. Nobody else can read your messages.
All essential messaging features, encrypted
Message freely, share files, and invite anyone to chat, with no phone number or personal details required.
Unified with Private.Ki Mail (one account, one app)
Messenger works inside the same encrypted system as Private.Ki Mail, using your single account and the same device-side keys.
There’s no separate login, no second app, and no additional setup.
Mail and chat operate as one system, seamlessly and securely.
Encrypted attachments
Files you send in Messenger are encrypted on your device before upload and remain encrypted at rest and in transit.
Private.Ki servers never see plaintext versions of your attachments.
Recipients decrypt files locally with their own keys, keeping shared content fully private.
Invite anyone — no signup required
You can start a secure conversation with anyone by sharing a private, encrypted chat link.
External users join through a temporary, end-to-end encrypted session without creating an account or providing personal information.
This keeps communication private and seamless, even with people outside Private.Ki.
No phone number or personal info required
Messenger doesn’t ask for a phone number, email verification, or identifying data.
You can use it anonymously or under a pseudonym, with your encryption keys providing the trust model — not external identifiers.
Privacy is built into onboarding, not added later.
Privacy that follows you across devices
Your messages stay encrypted and synchronized across all your devices. All keys remain on your side, and only your devices can decrypt your data.
Multi-device secure sync
Your conversations stay synchronized across all your devices using fully encrypted data.
No plaintext is ever transmitted or stored — only encrypted blobs that your devices decrypt locally.
Keys stay on your devices
Encryption and decryption happen on your device using keys that never leave it.
Servers store only encrypted data, so your keys remain fully under your control across all platforms.
Private-by-default behavior
All communication is encrypted before it leaves your device, with no identifiable metadata stored.
Privacy is built into every operation, keeping your chats protected regardless of where or how you use Messenger.
