1. Full Platform Coverage, Seamless Experience

2. Cloud Sync & Offline Access

3. Security & Privacy First

• Fully Open Source and Transparent: Code hosted on GitHub — anyone can review, audit, or build it themselves. No paywalls, trial periods, or feature restrictions.
• Enhanced Field Protection: Enable "protected" mode for specific fields (e.g., passwords), hiding them by default and storing them more securely in memory.
• Local-First Approach: All data encryption/decryption occurs on the local device; only encrypted database files are stored in the cloud.

  • Drag-and-Drop: Drag attachments or database files directly into the app window.
  • Keyboard Shortcuts: Extensive support for shortcuts to boost productivity.
