no real mature tool out there to fill that gap. this is why we built Chryptor.
people aren't going to move their whole life to a new app + apps get blocked anyway. Chryptor offers an offline keyboard that encrypts text and files before they move to Telegram, WhatsApp, email etc. the content stays unreadable to the platforms.
the key exchange part: you scan a QR code to add someone's public key, or agree on a passphrase together (ideally in person). both are stored in Chryptor for future use and always stay in your control. that's it.
no account, no servers, encryption works offline, plus a private local vault to keep sensitive files encrypted at rest.
encrypting files and text doesn't hide metadata or the SIM-linked number. but what people write stays unreadable to the platform (or anyone who gets into the platform's servers).
launching in December. everything about how it works is on the website (we will add more content about making the most out of the app and better protecting privacy), if you want to cover it in your guide.
