Nothing lasts.That's the point.
Sublemonable is end-to-end encrypted messaging that disappears. No logs. No screenshots. No trace.
x3dh handshake · new key per message
Encrypted before it leaves your hands.
Signal Protocol. Every message gets its own key. We store nothing readable. Not because the law says so — because it's technically impossible.
burn-on-read · 600ms
Read it. Watch it go.
Burn-on-read. Timed destruction. 30 seconds to a week — your call. The server deletes the moment your recipient gets it.
blocked
Screenshots? We blur those.
Android blocks them entirely. iOS and browser blur your messages the instant a screenshot is attempted. We also watermark every conversation — if something leaks, we know who did it.
scan to connect · no phone number
No number. No email. No name.
Connect by QR code. Your identity is a key pair we generate on your device. We don't know who you are.
How it works
Five steps. Zero knowledge on our end, start to finish.
Generate keys
Your device creates your identity. Keys never leave your device.
Exchange codes
Share a QR or link. No personal info changes hands.
Send encrypted
Every message encrypted locally before sending.
Delivered and deleted
Server purges message the instant it's delivered.
Gone forever
Set to burn, or burn on read. Nothing stays.
We show our work.
Sublemonable is open source. The encryption, the server, the apps — all of it auditable. Trust shouldn't require faith.
