About

Sogool

Features
Read full description

Sogool is a privacy-focused secure messenger that brings secure chat, private chat, video calls, voice calls, private notes, and file protection together in one app. No phone number, email registration, or separate account is required. Sogool is designed to keep conversations and personal data as device-centered as possible. P2P Secure Chat After the minimum signaling needed to establish the initial connection, Sogool secure chat allows users’ devices to communicate directly through P2P. Messages and files are encrypted on the sender’s device first and then sent directly to the other device. Chat content is not stored on Sogool’s service servers. The first one-to-one connection uses a 16-character secret key. Once the connection is established, the other person is registered as a secure friend on the device. After that, you can start a conversation from the secure-friends list without entering the secret key again. Video Calls · Voice Calls You can make video and voice calls with secure friends. Video and audio data are protected by WebRTC’s encrypted transport together with Sogool’s additional frame encryption. You do not need to open a chat room first. Choose a secure friend directly from the video-call or voice-call menu and start the call. Video and voice calls can be used without a separate limit on the number of calls. Private Notes Keep personal memos, journals, schedules, ideas, and other important records encrypted on your own device. Create and read notes without an internet connection. Sogool also supports image and file attachments, category management, and encrypted backup and restore. Private Notes work independently and do not require secure chat or a friend connection. File Protection Protect important photos, videos, documents, and other files with AES-256-based encryption on your device. Files are not uploaded to a Sogool server for encryption or decryption, and file protection can be used offline. Large files and a variety of file formats can also be encrypted and managed.
