Share Secrets
That Vanish.
Encrypted in your browser. Readable once. Then destroyed forever. We never see your data.
VanishingVault
Vanish your secrets safely with VanishingVault - secure one-time secret sharing
How it works
Encrypted in your browser.
Destroyed on read.
Encrypt locally
Your secret is encrypted in your browser with AES-256-GCM before any network call.
Store ciphertext
Only the encrypted blob and IV reach our Cloudflare KV store. The key never leaves your device.
Share the link
The decryption key lives in the URL fragment, which browsers never send to servers.
Vanish on read
On first view, the recipient decrypts locally and the ciphertext is permanently deleted.
Zero knowledge means zero compromise.
We mathematically cannot read your secrets. The architecture makes it impossible. Your data is encrypted before it leaves your device, and the key never touches our servers.
Why VanishingVault?
Privacy you don't have to take on faith.
Most services ask you to trust their privacy policy. We built a system where trust is irrelevant — the math prevents us from seeing your data, even if we wanted to.
Client-side encryption
AES-256-GCM runs in your browser before any network request. Your plaintext never leaves your device.
No server knowledge
The decryption key lives in the URL fragment, which browsers never transmit to servers.
Self-destructing
Permanently destroyed on first view, or automatically after seven days. No recovery possible.
No logs, no analytics
No IP tracking, no behavior profiling, no cookies required. We don't want your metadata.
Open source
Our encryption implementation is open for audit. Verify the code does what we claim it does.
No account needed
Share secrets instantly without creating an account, verifying an email, or handing over personal data.
Built for teams
Share credentials without the risk.
Onboarding a contractor? Sharing API keys with a teammate? Send a one-time link that self-destructs after reading. No Slack history, no email trail, no permanent record.
