B-Message is a privacy-first text encryption tool that locks your messages with industrial-grade AES-256-GCM encryption — right on your device. Your text never leaves your phone unencrypted, and not even we can read it. WHY B-MESSAGE? In a world where messages pass through countless servers, B-Message takes a different approach: everything happens locally on your device. There are no accounts, no servers processing your content, no logs, and no tracking. Your privacy isn't a feature — it's the foundation. HOW IT WORKS 1. Type or paste your message. 2. Set a password that only you and your recipient know. 3. B-Message encrypts your text instantly, on your device. 4. Share the encrypted result through any app you like — messaging, email, anywhere. 5. Your recipient decrypts it with the same password. The encrypted text is meaningless to anyone who intercepts it. Only someone with the password can unlock it. KEY FEATURES - AES-256-GCM encryption — the same standard trusted by security professionals worldwide - 100% on-device — your messages are encrypted and decrypted locally, never sent to any server - Zero data collection — no accounts, no analytics, no tracking, no logs - Works offline — encrypt and decrypt without an internet connection - Password-based — you control the key, we never see it - Simple and fast — clean, distraction-free interface - Share anywhere — use the encrypted output with any app you already use YOUR PRIVACY, GUARANTEED BY DESIGN B-Message is built on a zero-knowledge principle. Because encryption happens entirely on your device and nothing is transmitted to us, your private messages stay private — by design, not just by promise. PERFECT FOR - Sending sensitive information securely - Protecting private notes and messages - Anyone who values privacy and control over their data - Adding a layer of security on top of any messaging platform No sign-up. No data collection. No compromise. Developed by Beaver Byte.
