Proof, not promises

Your key has never met our server.

Encryption happens in your browser. Only unreadable ciphertext leaves your device, so a breach of our infrastructure cannot expose what we never possessed.

Only ciphertext crosses this boundary

Try it. Right now.

Type anything. Watch your browser do the real math.

This runs entirely in this browser tab — PBKDF2-SHA256 at 250,000 iterations, then AES-256-GCM. Nothing you type here is sent anywhere or stored.

Nothing here touches a server. Refresh and it's gone.

The comparison

What they ask for.What we never need.

Same notes. A completely different architecture underneath — and a shorter list of things you have to hand over.

Before you ask

Straight answers.No soft-focus privacy theater.

The questions people ask before trusting an encrypted vault with their private life.

What happens if I forget my passphrase?

Your vault becomes unreadable. There is no reset email and no recovery key — that trade-off is what makes zero-knowledge possible.

Can SEES read my notes?

No. Notes are encrypted in your browser before they ever reach storage, and SEES never receives the key that could decrypt them.

Has SEES been audited?

Not yet. We'd rather say that plainly than hide behind a security badge — treat it as early-stage software until an independent audit is published.

Built on one belief

Your private life should not be someone else's business model.
