Secure Notes for Windows
Secure Notes is a privacy-focused Windows journal and notebook application that stores your memories, notes, photos, and personal content inside a single encrypted KeePass KDBX 4.x database.
Built on open standards, Secure Notes gives you full ownership of your data. Your vault can be accessed using many compatible KeePass applications, ensuring you are never locked into a proprietary format.
