Talk Bi

【Product Introduction】 Talk Bi is an end-to-end encrypted application for local task requests and chat/office communication. Users can send messages and communicate with each other at any time. It primarily protects personal information and privacy through various information methods. The software uses RSA and SRP encryption to protect user information, and asymmetric encryption and double ratchet algorithms for transmission protocols and messages.

The product has undergone continuous technological upgrades and iterations to comprehensively protect your information security.

【Product Features】
1. Chat Encryption: End-to-end encryption; messages do not pass through the server.

2. Voice and Video: Supports encryption for various chat formats including text, images, voice, and video calls.

3. Chat Protection: Chat privacy protection functions such as automatic deletion, read receipts, and password unlocking.

4. Mass Chat: Super mass chat for tens of thousands of users.

5. Two-way Recall: Withdrawal is enabled for one-click two-way recall.

6. Task Request Circles: Users can set up to receive task requests in a specific area within a circle. Task requests posted by other users in the task request lobby will be displayed there, supporting text, image, and video posting. 7. File Encryption: Encrypt your favorite photo albums and share offline files with encryption.

【Product Features】
1. Assistant: Search for IDs of non-friends and check if they are in a violation status. Also check the number of contacts with you, in group chats, among friends, and in circles.

2. My Notes: Create and share product descriptions, images, text, videos, and store locations within your shop.

3. Super Album: After creating an album, share one or more albums via an encrypted link with nearby friends.

4. Agent Management: After creating an agent session, obtain the encrypted session link. Copy the link and send it to other third-party non-Talk Bi users to enable instant cross-platform chat between Talk Bi users and non-Talk Bi users. Supports simultaneous opening of multiple chat windows to send products, images, and requests to multiple non-Talk Bi users, making your promotions more reliable.

4. Message Grouping: Group messages for viewing in one-on-one chats, group chats, read status, and unread status.

5. Tag Grouping: Set tags for friends.

6. Enriched group functions: Group member protection, group member data protection, and group member muting.

7. Always uses end-to-end encryption; messages, calls, voice messages, images, videos, groups, and files are never stored on the server.

8. User Login: Proactively logs users who haven't used the app for a long time; they need to re-enter their password to log in again.

【Privacy Features】
1. Change User Password: Passwords can only be changed using the bound email, mobile phone, and security information, preventing account loss due to password leaks.

2. Login Device Management: You can view information about currently logged-in devices and kick out suspicious devices.

3. Lock Code Management: After setting a lock code, you need to enter this password to reopen the app when the phone is locked.

4. Privacy Management: You can set permission settings for friends, voice messages, groups, circles, etc. Avoid unnecessary harassment

5. File privacy: All text, images, voice, and video information you use in the APP are protected by RSA and SRP encryption. The transmission protocol and messages use asymmetric encryption and double ratchet (combining a symmetric key ratchet and a DH ratchet to form a double ratchet) algorithm. No one can obtain the original file information by using network packet capture, sniffing, or other methods, thus comprehensively protecting your information security.
