Sesam - Secure

Sesam protects what is yours: your messages, your photos, your papers, your passwords, your 2FA codes, your crypto. Everything is encrypted on your phone. Nothing leaves for a server — there is none. MESSAGES NO ONE ELSE CAN READ Sesam turns your message into an unreadable block. Send it anywhere — SMS, WhatsApp, email. Only the person who holds your key can read it, and that key is exchanged in person, by QR code: it never goes through the internet. Photos and videos included. The Sesam keyboard encrypts without leaving the app you're in, and your message can even hide between the letters of an ordinary conversation. A safety number, compared out loud, confirms no one slipped in between you; in doubt, renew the key in one gesture. YOUR 2FA CODES, NO OTHER APP NEEDED All your codes on one screen, with the service's logo and the countdown. Bring your accounts over in one go from Google Authenticator or 2FAS. Tick the ones you use most: they show on Apple Watch, iPhone still in your pocket — the watch computes them on its own, offline. Your messages can be read on your wrist too. A TRUE COLD WALLET Bitcoin, Litecoin, Ethereum and EVM networks — Polygon, Base, Arbitrum, Optimism, BNB Chain, Avalanche. The key is born on your phone and never leaves it. Before signing, offline and after Face ID, Sesam shows the transaction IN THE CLEAR: network, recipient, amount, maximum debit. No more blind signing. Your balance is checked via a watch-only export, and your 24 words stay encrypted in the vault. A SAFE IN YOUR POCKET Photos, videos, documents, notes, passwords: everything behind your code. Masked cards for your credentials, a clipboard that erases itself, a document scanner that never touches the photo roll. And from any app: Share, then Sesam. NO ONE KNOWS SESAM EXISTS Sesam can take the appearance of another app — about fifteen disguises, with the real icon and the real interface. A second code opens a decoy vault, a third erases everything. Before a border, travel mode makes your files unreadable. The access log tells you who tried to open, and when. Too many failures, or too many days without opening: everything is erased. NOTHING IS EVER LOST Twenty-four words, written on paper, are enough to recover everything on a new phone. A sealed archive under a secret phrase carries everything — without a server. On the Mac, Sesam waits in the menu bar. DON'T TRUST US. VERIFY. Switch to airplane mode: everything still works. Then open Settings, Privacy, App Privacy Report: next to Sesam, the list of connections stays empty. It's a record kept by your own phone.
