Snow10 is a small text-based steganography app that utilizes zero-width characters or tabs/spaces to hide messages in plain sight.
The encoded message can then be copy-pasted into a text message, social media messages, forum post, etc.
Using Snow10, secret messages can be hidden in almost any digital medium.
Encoded messages can optionally be encrypted with AES (password protected).
Important security notice/disclaimer: While we strive to create a secure app, no system is 100% secure. In addition, messages encoded with this app can be discovered by determined people or using specific tools. (Messages using the encryption setting can have their existance discovered but hopefully not their decrypted form assuming the code is secure and a strong password is used). This app relies on no network service.
While this app is listed as 0.99 USD, it is actually free and open source, and the source can be found in the repository: https://github.com/beardog108/snow10-android (GPLv3 license)
A free build of this app is available elsewhere, but we cannot say where because of Google's terms of service.
