Read full descriptionHide full description
Krypta ECC is a privacy-focused communication app that looks and functions like a regular calculator, but behind a secret code lies a secure, end-to-end encrypted chat system. It's designed for users who want private conversations without drawing attention. A Calculator with a Secret At first glance, Krypta ECC appears to be a simple, fully functional calculator. You can perform normal operations like addition, subtraction, multiplication, division, and percentage calculations. It works exactly as any standard calculator would. However, when you enter your personal secret code and confirm it, the app unlocks a hidden chat interface. Only you know how to access it, making your private messages truly discreet. Private and Secure Messaging Behind the calculator is a fully featured chat system, designed for direct and private communication between users. Each user creates a unique username and a personal app code. The code is stored locally and never shared with any server, ensuring that your access to the chat is entirely secure and private. You can start conversations in two ways: • By username: search and connect directly with another Krypta ECC user. • By invite link: share or open a secure link that instantly starts a chat connection. The messaging interface is simple and familiar, featuring real-time text communication, timestamps, delivery and read indicators, and privacy settings. You can also block unwanted contacts or report misuse directly in the app. End-to-End Encryption Every message you send or receive is protected with end-to-end encryption (RSA-2048 + AES-256-GCM), meaning only you and your chat partner can read the conversation. Even Krypta ECC's servers cannot decrypt or view your messages. All encryption keys are generated and stored locally on your device, never uploaded or shared. Messages are automatically deleted after delivery, ensuring your conversations remain private and temporary. Powered by Firebase Technology Krypta ECC uses Google Firebase to provide reliability, speed, and scalability: • Firestore: Real-time chat and message storage • Firebase Authentication: Secure and simple user management • Cloud Functions: Serverless automation for invites and moderation Discreet and Intuitive Design The app is designed for maximum discretion. No one will ever suspect there's a hidden chat behind your calculator. You can quickly return to the calculator screen at any time with a simple gesture or tap, making it safe to use in public or shared environments. The interface is clean, minimalist, and familiar. Whether you are calculating something or chatting securely, the experience is smooth, fast, and distraction-free. Privacy by Design Krypta ECC is built around privacy principles. Your personal information, conversations, and contacts are not tracked, analyzed, or sold. Only the essential data required for functionality is stored. The app follows GDPR-compliant data handling and allows you to delete your account and all related data at any time. No advertising, no tracking, no profiling — just secure, private communication. Content Moderation Krypta ECC includes comprehensive content moderation: • Automatic filtering of objectionable content • Report functionality for inappropriate behavior • Block functionality to remove unwanted contacts • Developer contact information available in Settings • All reports reviewed within 24 hours

theSHFT is the private messenger that forgets, by design. Say what you mean, and let it disappear on your terms. DISAPPEARING MESSAGES, DONE RIGHT Set a timer from seconds to 24 hours. Your messages expire from the moment you send, theirs from the moment they read, and unread messages never burn by the clock. Countdowns are instant and exact on both ends. END TO END ENCRYPTED, ALWAYS Every message, photo, video, voice note, story, and call is end to end encrypted. One to one chats add post quantum protection. Group messages advance their keys with every message. Nobody can read along, including us. A REAL VAULT Your conversations live behind your PIN or Face ID. A separate duress PIN wipes everything instantly if you are ever forced to open the app. No phone number required to sign up. Screenshots of your chats come out black. PRIVATE CALLS Voice and video calls are end to end encrypted with a fresh key for every call. Nothing is stored, nothing is heard. COMMUNITIES AND VOICE ROOMS Find your people in private communities like ^encryption-talk, with daily discussion threads, digests you control, and live voice rooms where you can host, raise your hand to speak, or just listen and leave quietly. STORIES FOR YOUR CIRCLE Share moments that vanish. Stories are encrypted and visible only to your contacts, enforced on the server, not just in the app. YOURS, NOT OURS No ads. No tracking. No selling your data. Your recovery phrase is the only way back in, and it belongs to you alone. theSHFT Pro unlocks video calls, unlimited call length, hosting voice rooms, extended timers, larger groups, the duress PIN, and panic wipe. Private. Secure. Yours.
