EXTRA SAFE: Encrypted Chat

EXTRA SAFE is a private chat application that prioritizes security and privacy. It allows users to make voice and video calls using an anonymous number, ensuring that their conversations remain private and protected. The app operates on a direct peer-to-peer (P2P) connection, which means that communication is not routed through a central server, making it less vulnerable to hacking or interception. One of the key features of EXTRA SAFE is its adherence to core GDPR principles, which means that user identities, metadata, and message history are not collected or stored. This is achieved through an identity-free setup and the use of on-device encryption keys. These keys are generated locally on the user's device, similar to how key pairs work in blockchain technology. This ensures that messages, files, and images are encrypted and can only be accessed by the intended recipient. The app also offers a timer feature, allowing users to set a custom time for their messages to remain visible. This means that the chat history automatically clears after the set time, providing an extra layer of privacy. Additionally, all messages are verified with a cryptographic signature, ensuring that they are sent and received by the intended parties. This signature includes a timestamp, preventing the reuse of old or stolen signatures. In addition to encrypted private chat, EXTRA SAFE also offers secure file transfer and private voice and video calls. File transfer is also encrypted and self-destructs after the set time, while calls are direct device-to-device and include an in-call chat feature. The app also allows for private P2P video meetings with up to 5 people, without any time limit. This can be done through a link, even if the other participants do not have the app installed. EXTRA SAFE is designed for individuals who prioritize secure messaging and private communication without sharing personal data or relying on centralized servers. It allows for the use of one number on multiple devices, providing convenience and flexibility for users. With its emphasis on privacy and security, EXTRA SAFE is a reliable option for those looking for encrypted messaging and private calls.
