EXTRA SAFE: Encrypted Chat

Secure Private Messaging and P2P Voice & Video Calls

Message with confidence using a private messaging app built for secure, encrypted chat. EXTRA SAFE lets you chat privately in E2EE chats that self-destruct by default. Set a timer, and all messages, files, and images disappear on your schedule.
Make private voice and video calls using your anonymous EXTRA SAFE number over a direct P2P connection, secured by on-device encryption keys.

EXTRA SAFE is a secure private chat app built on core GDPR principles. You get:
– An identity-free setup.
– Direct device-to-device communication (P2P).
– E2EE messages, files, and images with cryptographic keys generated locally on your devices. Just like key pairs work in blockchains like Ethereum.
– No collection of user identities, metadata, or message history: storage is encrypted and temporary by default, following your timer.

KEY FEATURES
1. Encrypted Private Chat
Your text and voice messages are protected with E2EE, so only you and your contact can see them. Everything you send is encrypted on your device, stays encrypted while in transit, and is decrypted only when it reaches your contact’s device. In the app, your identity is verified with a cryptographic signature. You sign requests with your private key, and the server can confirm that the action was performed by you. Every signature includes a timestamp, so old or stolen signatures can’t be reused.

The chat history clears by default – you decide how long the messages stay visible. Set a custom timer for each chat, from one minute to one month. Once your contact views the message, it will disappear automatically within the time you choose.

2. Encrypted File Transfer
Send files of any type, images, and videos up to 25 MB. File transfer is also E2EE, and since EXTRA SAFE chats self-destruct by default, everything you share will disappear at the custom time you set.

3. Secure Private Voice & Video Calls
Direct device-to-device calls with a phone-like experience, including P2P encrypted in-call chat, that vanishes once the call ends (supports messages and file transfer).

4. Private P2P Video Meetings
Start a video call with up to 5 people, with no time limit. Anyone can join your call via a link, even if they don’t have the app installed.

EXTRA SAFE is designed for anyone looking for secure messaging, private chats, encrypted messaging, and private calls without sharing personal data or relying on centralized servers.

You can use one EXTRA SAFE number on multiple devices.
