Send a private message — no account
Share private messages as an encrypted one-time link, without registration and without an app. Encryption happens in the browser; the key stays in the URL fragment after # and is never sent to the server.
What zero-knowledge gives you
- No account and no app required
- Client-side encryption in the browser
- Read-once and expiry against lasting traces
- Verify with F12 that the key stays local
Private, and what that does not cover
Private here means confidential in transit and at rest: the content is encrypted before upload, the key stays in your browser, and the server holds nothing it can read. No account is required, so there is no profile accumulating alongside your messages.
It does not mean anonymous. A connection still has an IP address and a timestamp, and those can be observed at the network level regardless of what the payload contains. If unlinkability is your requirement, confidentiality alone will not deliver it.
It also does not authenticate the person at the other end. The link proves possession, not identity. Where that distinction matters, recipient approval adds a step: the content is only released after you approve the specific device that asked for it.
Frequently asked questions
How do I send a private message without an account?
Open pcpx.one, write your message and create an encrypted link. No registration. Share the link with the recipient, who can open it without an account.
Is the message really private?
Encryption happens in the browser and the server only stores encrypted data. Without the key in the URL fragment nobody can read it.
