Digital Diary is a personal productivity platform that integrates encrypted account management, note-taking, visual planning, and financial tracking into one secure workspace. The encrypted accounts module stores login credentials, passwords, and two-factor authentication codes under AES-256-GCM encryption, with passwords decrypted only in memory when accessed. The smart notes feature supports markdown formatting, tag-based organization, and full-text search for efficient idea management. The visual planner offers an infinite canvas for mapping workflows with interactive drag-and-drop nodes and connection handles. The financial ledger tracks budgets, invoices, and expenses with automatic balance calculations and monthly summaries. Data syncs in real-time via MongoDB Atlas with TLS-encrypted transport. The zero-knowledge privacy architecture maintains security through isolated user schemas, JWT sessions stored in HTTP-only cookies, and bcrypt password hashing protocols.
