How it works

1

Paste your secret

Password, API key, private note — anything sensitive.

2

We encrypt it

AES-256 encryption happens in your browser. We never see the content.

3

Share the link

Send it via Slack, email, SMS — any channel you trust.

4

It self-destructs

After one view, the secret is permanently deleted.

Why it's secure

Zero-knowledge

Encryption happens in your browser using the Web Crypto API. The decryption key is in the URL fragment, which never reaches our servers.

AES-256-GCM

Military-grade encryption with authenticated encryption. Tamper-proof — any modification is detected and rejected.

Auto-destructing

Secrets are permanently deleted after being viewed once. You choose the expiry: 1 hour, 24 hours, or 7 days.

Optional PIN

Add a PIN for extra protection. Even if the link is intercepted, the secret can't be viewed without it. Burns after 5 wrong attempts.
