Lucive

Lucive is a journal and planner that keeps everything you write private.

Every entry is encrypted end to end and stored on your own device. When your devices sync, they talk through a relay that only ever handles sealed, opaque data. It cannot read your entries, and neither can we. There is no cloud account for your journal, no analytics, and no telemetry.

WRITE
• A clean editor with full markdown support
• Keep separate journals for separate parts of your life
• Link entries to each other and follow the threads back
• Slash commands for quick formatting as you type
• Fast full-text search across everything you have written

PLAN ACROSS EVERY HORIZON
• Plan by day, week, month, and year, with each horizon nested in the next
• Give any period a focus, so you always know what this week is actually for
• Commit tasks to a period, or keep them as references for when there is room
• Today shows what you set out to do; Upcoming shows what is heading your way
• Recurring tasks for the things that keep coming back around
• Reminders that reach you on your iPhone and your Mac
• Drag to reorder, act on many tasks at once, and undo when you change your mind
• A scratchpad for catching thoughts fast, archived day by day

SYNC BETWEEN YOUR OWN DEVICES
• Pair a device by scanning a QR code, exchanging keys directly between them
• Everything stays encrypted end to end in transit
• Works fully offline; your changes sync when you reconnect

KEEP IT PRIVATE
• Lock the app behind a password, with an inactivity timer you set
• Entries are hidden behind a blur in the app switcher
• A 12-word recovery phrase means you never lose access to your own writing
• Modern, well established cryptography: XChaCha20-Poly1305 and Argon2id

Lucive is also available on Mac, so you can plan at your desk and pick up where you left off on your phone, with the same end-to-end encrypted sync between them.

A journal only works if you are honest in it, and honesty needs privacy. Lucive is built so that what you write stays yours.
