## What is Open Keep?

Open Keep is a simple, privacy-focused note-taking app designed for users who want full control over their data. No account required, no personal data collection - just your notes, stored how and where you choose.

Write notes using clean and powerful Markdown (.md), protect sensitive content with passcode protection/biometrics, and keep everything in sync across your devices using your preferred cloud storage provider.

Key Features:

- Privacy-focused – No account required, no vendor lock-in
- Cloud sync (Dropbox, Google Drive, OneDrive)
- Markdown Files (.md) – Write and edit notes in a standard, portable format
- Password Protection – Secure your notes with passcode/biometrics
- Import & Export Notes – Easily move your data in or out at any time
- Encrypted – 256-bit AES encryption, which is an industry standard (often referred to as military-grade encryption)

Open Keep is ideal for users who value privacy, data ownership, and open formats - whether you’re taking quick notes, writing documentation, or managing personal knowledge.

Your notes. Your storage. Your control.
