IRONDOTS CHAT

IRONDOTS CHAT allows you to send and receive encrypted text messages through sound waves.
The app does not connect to the internet and all encrypted messages are only transmitted by sound or ultrasound.
To receive incoming messages, you only need to allow access to your device's microphone.
THE IRONDOTSCHAT PRINCIPLE
IRONDOTSCHAT protects your messages from access by hackers, companies and governments through physical separation and end-to-end encryption. The app can be used completely anonymously (without registration; without providing a phone number or email address). IRONDOTS is based on the "box" model of the open source NaCl Networking and Cryptography Library to transmit messages with a maximum length of 40 characters encrypted through sound waves.
COMMUNICATE WITHOUT TRACES
IRONDOTSCHAT is designed for offline operation, without an internet connection. We have simply not implemented the possibility to communicate with the Internet or other devices. Your secret certificate is stored encrypted with your password on the mobile phone/tablet. All this prevents the collection and misuse of personal information. IRONDOTS is fully compliant with the European Data Protection Act (DPA).
BEST ENCRYPTION
All messages are always end-to-end encrypted. You can be sure that no one except the intended recipient can read your messages. The key pair is generated and stored encrypted directly on your device. 256-bit long asymmetric keys are used, which are generated using elliptic curve cryptography (Curve25519). This asymmetric key is used to obtain a unique 256-bit symmetric key for each message sent.
NO ADS, NO TRACKERS, NO COOKIES
