Privdo

About

Privdo is a privacy-first todo manager. All your data is encrypted with AES-256 and stored locally on your device — nothing is sent to any server unless you explicitly enable optional end-to-end encrypted sync.

Core Features
• PIN-protected vault with AES-256 encryption (PBKDF2, 600k iterations)
• Multiple named task lists (work, personal, etc.)
• Drag-and-drop reordering
• Deadlines with overdue highlighting
• Instant search across tasks
• Dark and light mode
• Collapsible completed-tasks section
• Export and import encrypted JSON backups

Optional E2E Encrypted Sync
• Sync across devices via passphrase or email — your choice
• Zero-knowledge server: the server never sees your plaintext data
• Conflict-free merge with last-write-wins per field
• Works offline — queued changes sync automatically when you reconnect

Privacy by Design
• No account required
• No tracking, no analytics, no ads
• PIN never leaves your device
• Raw storage is opaque ciphertext
• Open source: https://github.com/chsafouane/local-todo-manager

Privdo is also available as a web app, macOS desktop app, and iOS/Android app.
