Hey @Hemant Kumar
Thx for writing back. Let me float a raw idea, where you can split the application into core and UI. Now core part is opensource and you keep the UI closed source.
Core:
Database
Encryption code
Authentication (Most important: This should pop up UI to enter master password and grant temporary access to UI without revealing master password)
Let me know if you get the gist; ping me back if something is unclear
Thx
Hey @Unsay
