End-to-end encrypted messaging, files, and tools — engineered so your data stays yours. Private by design, protected by default.
Threadlock brings your digital life together with powerful tools and uncompromising security.
THREADLOCKMessages, files, and vault entries are encrypted on your device before they ever leave it. Your keys never touch our servers — so no one, not even us, can read what you lock.
Most apps say they protect you. Threadlock is built so we can't read your data even if we wanted to — because your keys never leave your device.
Every prize is a badge, a number, or a theme. Nothing you win changes what your account can do — security, storage and privacy are the same for everybody, always.
Join before August 1st and claim a founder number. Assigned in order, locked in for good — the first 25 get an extra badge.
Find a real bug and earn the Whitehat badge. Three accepted reports makes you a Bug Hunter. Test your own account only.
Five signups from your invite link earns Recruiter. Top ten on the board at launch earns Ambassador and a low founder number.
We held back a pool of two and three character usernames. Ask for one and we hand them to people actually using the app.

Yes. The core platform is free forever — no card, no trial. We may add optional paid extras later, but privacy and encryption are never behind a paywall.
Your messages, files, and vault entries are encrypted on your device with a key derived from your passcode. That key never reaches our servers, so we only ever hold unreadable ciphertext. We can't read your content, and we can't hand it over.
Use a recovery code you saved, or an admin can reset it. Passcodes themselves can't be recovered, only reset — that's by design, and it's what keeps them safe.
Yes. Create a business account, share one join code, and manage your team in a private encrypted workspace. There's a separate business sign-in built just for that.
No tracking, no ads, ever. We don't sell data — encrypted or otherwise — and there's nothing to sell, since we can't read it.
