Ciphar vs Privnote — One-Time Notes vs Real-Time Chat
Privnote and similar "burn-after-reading" tools are excellent for a very specific job: handing someone a single piece of secret text — a password, a recovery phrase, a one-time link — that vanishes after they read it once. Ciphar covers the next step: when you need to actually have a back-and-forth conversation under the same self-destruct constraint.
The short answer
Use Privnote when you need to deliver a single secret payload, no reply needed. Use Ciphar when you need a conversation — multiple messages, files, optional voice — that disappears on a timer.

When to use Privnote instead
- You need to send one secret string to one person.
- The recipient does not need to reply.
- You want the secret destroyed the moment it is opened, regardless of clock time.
When to use Ciphar instead
- You need a back-and-forth conversation, not a one-shot note.
- You want to share files in addition to text.
- You may want to switch to encrypted voice mid-conversation.
- More than two people need to participate.
- You want a fixed-time self-destruct rather than first-read self-destruct, so a session can keep going for an hour without resetting.
Common pattern: chain them
A common workflow: send the Ciphar channel link in the clear, then send the access key over Privnote. The link by itself is useless without the key, and the key is destroyed after the first read, leaving no trace anywhere of how the channel was reached.
