Day0: Private Diary

Day0 is a diary that only you will ever read. Log the moments that matter: who they were about, when they happened, and a note only you need to understand. Everything stays on your phone. When you change phones, export an encrypted backup file and restore it on the new phone. What's inside: • Log a moment in a few taps, or let the built-in timer keep the record for you • Build a quiet profile for each character you care about: birthday, aliases, your own notes • Keep track of the things you've collected, and watch the cost of each use settle over time • Review your history as calendars, timelines, and monthly look-backs • Lock your most private notes behind Face ID; the lock screen shows none of them, and widgets show only what you choose • Nine hand-tuned themes, a quiet mascot, and achievements that never nag • Encrypted backups you control, exported as one file that opens with your restore code There's no streak to keep, no leaderboard, no nudging. Write as much or as little as you want. Day0 keeps the record, quietly.
