Quantext: Hide your Messages

Need to share a private note without abandoning the communication apps you already use? You need a simple way to seal a note on your device and share the text and the key separately.

Most secure communication requires everyone to install a brand new messenger and create accounts. Quantext is a compact text vault that changes this by sealing text you intend to paste elsewhere. Simply type your message, choose an active labeled key, and encrypt the text with on-device AES-256-GCM. The app generates a sealed envelope that you can copy and paste directly into your current SMS or email thread. Because it is purely a vault and not a chat app, you never have to sign up for a Quantext account, keeping you completely in control of your shared secret.

✨ Key Features & Benefits

🔒 On-Device AES-256-GCM: Quantext uses Web Crypto AES-256-GCM directly on your device to seal messages. This ensures your data is processed locally before you share the sealed text across other apps.
🔑 Labeled Keyring: Store multiple shared secrets with custom nicknames you choose. This allows users to keep more than one labeled secret on the same phone and easily tell them apart visually.
📱 No Account Required: Generate your key and unlock messages without signing up for any service. Quantext does not host messages or keys, meaning your data stays out of first-party cloud syncs.
⭐ Vault Lock & Premium: Free users can manage up to four usable labeled keys. Upgrading to Premium offers an ad-free experience, unlimited key storage, and a vault passphrase to blur key nicknames from shoulder-surfing.

🏆 Why Choose Quantext?
Developed by Knox Studios, Quantext is designed with a dark, compact vault UI rather than a social layout. It provides a factual, serious approach to securing your private notes, giving you a straightforward tool to encrypt your clipboard data without overpromising anonymity.
