Send secrets that self-destruct
Encrypted in your browser. Burned after reading. Works once — then vanishes from every server, forever.
Encrypted locally · Server never sees plaintext or your key
Zero knowledge · Always
How it works
Type your secret
Write your message or attach a file. Your browser encrypts everything locally using AES-256 before sending anything.
Get a one-time link
You receive a unique link. The encryption key is embedded in the URL fragment — it never reaches our servers.
It self-destructs
When the recipient opens the link, the message decrypts locally in their browser — then vanishes from our servers forever.
Not just "send a secret"
8 ways to protect what matters
Every mode is free to try. Each one solves a problem that no other tool handles.
Burn After Reading
The classic. Zero trace.
Text or file. Link works once — then the data is gone from every server. Forever.
Time Capsule
Send a message to the future
Write now. Choose a date: 1 year, 5 years, your kid's 18th birthday. Opens only then.
Simultaneous Swap
Both see at the same time
You both write a secret. Neither reads first. Both reveal at once. Perfect for salary comparisons, confessions, negotiations.
Plausible Deniability
Two passwords. Two truths.
Real secret + convincing decoy. Under pressure, hand over the decoy link. Cryptographically impossible to prove which is real.
Dead Man's Switch
Releases if you go silent
Check in every N days. If you stop — the secret fires automatically to your designated recipient. For journalists, whistleblowers, contingency planning.
Honeypot Canary
Find your insider threat
Distribute unique copies to suspects. Monitor which one gets opened. Identify the leaker instantly. Enterprise insider threat detection.
Bulk Create
100 credentials in 30 seconds
Upload a CSV. Get a CSV back with 100 unique one-time encrypted links. Perfect for IT onboarding and team password resets.
Voice Note Secret
Record. Encrypt. Burns after listening.
Record a voice message that self-destructs after the recipient listens. No trace. No recording. Encrypted locally in your browser.
Why CipherEdge
Built different from every competitor
Zero-Knowledge
Your browser encrypts everything locally. We receive ciphertext only — mathematically impossible for us to read.
Burns after reading
The moment a secret is opened, it's simultaneously deleted. The second request always gets a 404.
Bot-Safe Gateway
Slack, Telegram and Discord bots burn links on preview. Our edge gateway detects bots and serves them a safe placeholder.
Edge Delivery
Runs on 300+ global edge locations. Sub-50ms response times worldwide. No cold starts.
Audit Logs
B2B teams get immutable logs: who created a secret, when it was opened, from which IP. SOC2-ready.
GDPR Compliant
EU-only data residency available. Zero personal data processed — we can't read content we never receive.
