Your conversations stay yours

Lucid is a client, not a middleman. It holds no provider keys of its own, so there is nothing here for anyone to mine.

We hold no keys

Your provider key stays in your browser and is sent only with the request that needs it. It is never written to our database.

Files delete themselves

Uploads expire 24 hours after you send them and are removed by a job that sweeps daily, and again whenever you use Lucid. Enforced in code, not promised in a policy.

Nothing is tracked

No analytics SDK, no advertising SDK, no third-party tracker. Not disabled by default: not present at all.

One caveat we will not hide: your prompt goes to the provider you chose, and what they do with it is governed by their terms, not ours. Read the full policy.

Bring your own key. Keep your own data.

Connect an account you already pay for and start in under a minute.
