Cipheus

Is this two aliens talking? It might be. Or it might be your group chat in Cipheus. โ Cipheus turns every text you send into ancient runes, celestial symbols, or geometric glyphs. Your friends with the same Language Pack see the real message. Anyone glancing at your phone sees... something they can't read. It's not magic. It's not really alien. But it kind of looks like both. โ WHAT IT'S FOR - Group chats your parents/siblings/coworkers shouldn't read - Aesthetic texting (your messages look cool now) - A private second layer for conversations that matter - Just for the vibes, honestly โ HOW IT WORKS Pick a Language Pack โ Nordic Runes, Celestial, Geometric, and more. Share it with one friend or a whole group. Every message you send turns into symbols. Long-press to see what's underneath. It's encrypted end-to-end. Even I (the dev) can't read your messages. That's the point. โ FROM THE DEV Hi, I'm Flood. I built Cipheus solo because I wanted texting to feel like a secret again. The kind of secret you and your best friend share in a language no one else speaks. I'm still adding Language Packs, fixing rough edges, and listening to everyone using it. Send feedback. I read everything. โ CIPHEUS+ (Optional) Unlock unlimited Language Packs and unlimited friends. $3.99/month or $29.99/year. Cancel anytime. โ Privacy Policy: cipheus.com/privacy Terms: cipheus.com/terms Contact: cipheus.com (yes I read DMs) cipheus.com

P2P Secure Chat & AES-256 Encrypted Notes/File Management โ No Relay Server Welcome to Sogool, a 100% P2P secure chat and AES-256 encryption-based personal privacy management tool. Sogool is designed to fully protect your personal information and valuable data from external threats. After the initial connection, all communication is handled via direct P2P without any relay server, combined with powerful local encryption technology to deliver true privacy. โฃ No Account Required - Most apps require sign-up or other verification before use. Sogool skips all of that, keeping your privacy completely in your hands. โฃ Key Features 1. 100% P2P Secure Chat (No Relay Server) - Serverless Communication: After the initial signaling phase, devices connect directly (P2P) without passing through any relay server. - Strict Security: Only users with the room key (secret key) generated by the host can join. All conversations and files are sent and received directly in an encrypted environment. - No Trace Left: Once the socket connection is closed, no records remain on any server, making data theft fundamentally impossible. 2. Secure Private Notes (Full Offline Support) - Smart Recording: Freely record diaries, ideas, recipes, and more using an editor that supports file attachments. - Organized Management: Use category grouping to safely classify and protect your personal knowledge base. - Backup & Restore: Encrypted backup files compatible across devices are provided. With just your secret key, you can instantly and safely restore your data on any device. 3. Secure File Vault (Large File Support) - Powerful Local Encryption: Important files such as documents, photos, and videos are encrypted on-device using the world-standard AES-256 method. - Large File Optimized: A dedicated process ensures stable encryption and decryption of large files without delay. - Fully Offline: All encryption is performed in a completely local environment without a network connection, eliminating any risk of external leakage. โฃ Why Sogool? - Since no relay server is used at all, the scenario of data leakage through server hacking simply does not exist. - You can safely write personal notes and manage encrypted files even in an offline environment without an internet connection. - No tedious sign-up process. The secret key you set is the strongest security there is. - To support the service, ads may be displayed on some screens. โฃ Safe and Responsible Usage Guidelines (UGC Policy Compliance) Sogool provides technical privacy while strictly complying with Google's User Generated Content (UGC) policy to maintain a safe community environment. - A [Report and Block] system is in place to immediately report illegal content and malicious users within chat rooms. - In cases of repeated reports or confirmed policy violations, the user's access to the service may be restricted. - Opening chat rooms that infringe on others' rights or violate applicable laws is strictly prohibited.
