Share secrets that vanish.
Encrypted in your browser, readable only once, automatically destroyed. We never see your data — ever.
How it works
Encrypted in your browser. Destroyed on read.
- 01
Encrypt locally
Your secret is encrypted in your browser with AES-256-GCM before any network call.
- 02
Store ciphertext
Only the encrypted blob and IV reach our Cloudflare KV store. The key never leaves your device.
- 03
Share the link
The decryption key lives in the URL fragment, which browsers never send to servers.
- 04
Vanish on first read
On first view, the recipient decrypts locally and the ciphertext is permanently deleted.
Why Zero-Knowledge?
Privacy you don't have to take on faith. The architecture mathematically prevents us from reading your data.
Client-side encryption
AES-256-GCM runs in your browser before any network request.
No server knowledge
The decryption key lives in the URL fragment, never transmitted.
Self-destructing
Permanently destroyed on first view, or after seven days.
