Post Anonymously Online

If you want to say something anonymously without signing up for anything, Letheca is built for exactly that moment. No registration. No email. No phone number. No profile. No social graph. Just a temporary post that disappears after 24 hours.

How to Post Anonymously

  1. Open the board. No account or download needed. Letheca works in any browser on any device.
  2. Write something. Up to 500 characters. Say what you need to say.
  3. Submit. Your post goes live immediately and is visible to anyone on the board.
  4. Walk away. After 24 hours, your post is permanently deleted. No record of it remains.

That is the entire process. There is no signup flow, no verification step, and no "create your profile" screen. Letheca does not know who you are because it does not ask.

What Makes This Actually Anonymous

Many platforms claim to offer anonymous posting but still collect identifying information behind the scenes. Letheca takes a different approach:

This is anonymity by design, not by policy. The system cannot identify you because it does not collect the data needed to do so.

When Anonymous Posting Is Useful

There are moments when saying something under your own name carries more risk than the statement itself warrants:

Letheca is a low-stakes outlet for these moments. Say it, release it, and let it disappear.
