In a statement on January 12, an NIA spokesperson had said: 'Till recently Rahman was in regular communication with ISIS terrorists located abroad as well as in India, including Sami on 'Threema', a secure messaging platform.' Wani and Beigh were arrested in March 2020, while Rahman in August. On the other side, Signal is open source (Threema is 'only' audited multiple times), is also usable as SMS application and is currently developing a Web client (we all hope that Threema is as well, but we don't know).The NIA during its probe into the Islamic State Iraq and Syria Khorasan Province (ISIS-KP) case has found that arrested accused Jahanzaib Sami Wani and his wife Hina Bashir Beigh and Bengaluru-based doctor Abdur Rahman aka 'Dr Brave' were using Threema, a secure messaging platform. Privacy options like read-indicator, writes-indicatorĭetailed, per-chat notification settings, export chats into an encrypted zip, usable without Google play services (though the battery live isn't that good without GCM), tablet optimized version. Small, but (imo) neat feature: You can scan and generate QR codes to/from a message. The app can be locked with a PIN, a password or with your android system lock (pattern, fingerprint)

In groups you can create polls (comparable to doodle?)

You can use Threema on devices without a SIM-card, even without having a phone number at all. If you trust Threema, you can install the QR-scanner and voice message plugin. Permissions in Threema for Android are modular, so you can install it without granting microphone and camera permission. So you can sync your adress book, but at the same time you could give a stranger an opportunity to contact you without giving away your number. You have an anonymous ID, which is not tied (but can be connected) to a phone number. Here are a few cool things Threema has, but Signal doesn't:
