theSHFT - Encrypted Messaging

theSHFT is a private messaging app built for people who take privacy seriously.
Everything is encrypted on your device before it's sent — messages, calls, photos, and voice memos. We never see it. No one does.
Send texts, photos, videos, and voice memos with full end-to-end encryption. Each message uses its own encryption key with forward secrecy, so even if one key is compromised, nothing else is affected.
Your one-on-one messages go a step further: they're protected with post-quantum encryption (ML-KEM-768) in hybrid with classical encryption — safe against today's threats and tomorrow's quantum computers.
Messages automatically disappear after being read. Set timers from 5 seconds to 24 hours and watch a live countdown to the exact second it's gone. Once it disappears, it's permanently deleted from both devices.
Make encrypted voice and video calls secured with AES-256. Keys are derived from your existing secure session, so your calls stay private from start to finish.
Create encrypted group chats with up to 50 members (100 with Pro). Encryption keys rotate automatically when members change, and removed users can't access future messages.
Send voice memos with a visual waveform and scrub through playback. Like everything else, they're encrypted and self-destruct on your timer.
No phone number. No email. No personal information. Just a username and a PIN. Your 12-word recovery phrase is the only way to restore your account, and only you have it.
Screenshots and screen recordings are blocked inside the app. If someone manages to capture the screen, the other person is notified instantly.
Built on proven cryptographic protocols with forward secrecy, theSHFT uses a zero-knowledge architecture. Keys are generated and stored only on your device. We cannot read your messages, even if asked.
A duress PIN lets you instantly wipe all data without warning. No alerts. No traces.
theSHFT delivers real-time messaging, encrypted voice and video calls, group chats, voice memos with waveform playback, and live countdown timers on every message.
The free plan includes core messaging features with limits on contacts, messages, and timer length.
Upgrade to Pro: a monthly or yearly subscription to unlock unlimited messaging, media, and contacts, encrypted video calls, extended timers, larger groups, and the duress PIN.
Private. Secure. Yours.
