Introducing SimpleX Chat: The Most Secure Messaging App

SimpleX Chat is a messaging app that prioritizes your privacy and security. Developed by Trail of Bits, this app offers end-to-end encryption for all your messages, along with a range of other features to keep your conversations safe and secure.

Features of SimpleX Chat

SimpleX Chat offers a range of features to make your messaging experience secure and convenient. These include:

End-to-End Encryption

All messages sent through SimpleX Chat are end-to-end encrypted, meaning only the sender and receiver can access them. This ensures that your conversations remain private and cannot be intercepted by anyone else.

Disappearing Messages

With SimpleX Chat, you have the option to send disappearing messages that will automatically delete after a set period of time. You can also choose to opt-out of this feature for specific contacts or groups.

Message Reactions and Delivery Receipts

SimpleX Chat now offers the ability to react to messages and receive delivery receipts, giving you more control over your conversations.

Multiple Chat Profiles and Incognito Mode

You can create multiple chat profiles on SimpleX Chat, and even hide certain profiles for added privacy. The app also offers an incognito mode, unique to SimpleX Chat, for even more discreet messaging.

Secure File Sharing and Voice Messages

SimpleX Chat allows you to send end-to-end encrypted images, files, and voice messages up to 5 minutes long. This ensures that all your shared content remains secure and private.

Secret Chat Groups and Audio/Video Calls

With SimpleX Chat, you can create secret chat groups that only members know about. The app also offers end-to-end encrypted audio and video calls for secure communication.

Connection Security Code Verification

To protect against man-in-the-middle attacks, SimpleX Chat offers connection security code verification for contacts and group members.

Private Instant Notifications and Encrypted Portable Chat Database

SimpleX Chat offers private instant notifications and an encrypted portable chat database, allowing you to transfer your chat contacts and history to another device securely.

The Advantages of SimpleX Chat

SimpleX Chat offers several advantages over other messaging platforms, including:

Privacy of Your Identity and Data

Unlike other messaging apps, SimpleX Chat does not use phone numbers or any other identifiers assigned to users. This ensures that your identity and data remain private and hidden from the app's servers and any observers.

Protection Against Spam and Abuse

As SimpleX Chat does not use any identifiers, you are protected against spam and abuse. You can only be contacted if you share a one-time invitation link or a temporary user address.

Full Ownership, Control, and Security of Your Data

All user data is stored on client devices, and messages are only held temporarily on relay servers until they are received. This gives you full ownership, control, and security of your data.

Decentralized Proxied Peer-to-Peer Network

SimpleX Chat allows you to use your own relay servers and still communicate with people using pre-configured or any other SimpleX relay servers. This decentralized network adds an extra layer of security to your conversations.

Open-Source Code

The code for SimpleX Chat is fully open-source, meaning anyone can view and verify the app's security and privacy features.

How to Use SimpleX Chat

Using SimpleX Chat is easy and straightforward. Simply connect with anyone you know via a link or QR code and start sending messages instantly - no emails, phone numbers, or passwords needed.

Your profile and contacts are only stored on your device, and relay servers do not have access to this information. All messages are end-to-end encrypted using an open-source double-ratchet protocol and delivered via relay servers using the open-source SimpleX Messaging Protocol.
