Your master password never leaves your device, so only you can access your encrypted notes - not even we can. All of your data is sealed with AES-256 bit encryption, and PBKDF2-SHA-256 (100k Iterations).
Ciphernote will be initially released for Windows Desktop and Tablets. Versions for other platforms such as macOS, Android and iOS following after the Windows Beta Phase.
Your notes only leave your devices in encrypted form and are stored in the cloud. As additional protection we replicate your (encrypted) notes to multiple data-centers in different geographic regions.
