BTWN – Hide Messages in Photos

关于此应用

BTWN lets you hide encrypted text messages inside ordinary photos. To anyone looking at the image — it's just a photo. Only the person with the password sees what's between the pixels. HOW IT WORKS Tap Encrypt, write your message, set a password, and choose a photo. BTWN invisibly embeds your encrypted text into the image using steganography — the science of hiding data inside other data. Share the photo anywhere. On the other side, tap Decrypt, upload the photo, enter the password, and your message appears. The photo looks completely unchanged. The message is completely hidden. WHY BTWN IS DIFFERENT - AES-256 Military-Grade Encryption — Your message is encrypted before it's hidden. Even if someone discovers the technique, the content is unreadable without your password. - Zero Servers — BTWN never transmits your data anywhere. There is no backend. There are no accounts. Nothing is stored in the cloud. - Fully Offline — Works with zero internet connection. Encrypt and decrypt entirely on your device. - No Account Required — Open the app and start using it. No sign-up, no email, no phone number. - Works with Any Sharing Method — Send the image over iMessage, WhatsApp, email
