theSHFT vs CallSec

theSHFT is the private messenger that forgets, by design. Say what you mean, and let it disappear on your terms. DISAPPEARING MESSAGES, DONE RIGHT Set a timer from seconds to 24 hours. Your messages expire from the moment you send, theirs from the moment they read, and unread messages never burn by the clock. Countdowns are instant and exact on both ends. END TO END ENCRYPTED, ALWAYS Every message, photo, video, voice note, story, and call is end to end encrypted. One to one chats add post quantum protection. Group messages advance their keys with every message. Nobody can read along, including us. A REAL VAULT Your conversations live behind your PIN or Face ID. A separate duress PIN wipes everything instantly if you are ever forced to open the app. No phone number required to sign up. Screenshots of your chats come out black. PRIVATE CALLS Voice and video calls are end to end encrypted with a fresh key for every call. Nothing is stored, nothing is heard. COMMUNITIES AND VOICE ROOMS Find your people in private communities like ^encryption-talk, with daily discussion threads, digests you control, and live voice rooms where you can host, raise your hand to speak, or just listen and leave quietly. STORIES FOR YOUR CIRCLE Share moments that vanish. Stories are encrypted and visible only to your contacts, enforced on the server, not just in the app. YOURS, NOT OURS No ads. No tracking. No selling your data. Your recovery phrase is the only way back in, and it belongs to you alone. theSHFT Pro unlocks video calls, unlimited call length, hosting voice rooms, extended timers, larger groups, the duress PIN, and panic wipe. Private. Secure. Yours.
