A daily journal built on creative constraints. One note per day — no folders, no tags, no decisions. Yesterday's notes become read-only, keeping you present instead of endlessly editing the past. End-to-end encrypted so you can trust it with your most private thoughts — not even we can read them. Runs entirely on your device as a PWA. No internet required. No account required. Open the app, start writing.

Hey Product Hunt! 👋 I built Ichinichi because I wanted a daily journal that: 1. Let me start writing in under 2 seconds 2. Encrypted my thoughts so nobody — not even the app operator — could read them 3. Didn't guilt me into organizing anything The core idea: one note per day, encrypted on your device, viewable on a calendar. That's the whole app. The encryption is real — AES-GCM with PBKDF2 key derivation (600k iterations). Your notes are encrypted client-side before touching any server. In local mode, there's no server at all. Some things I'm proud of: - Zero to writing in 1 click — no signup wall - Visual streaks — the calendar dots are surprisingly motivating - Read-only past — you can't "cheat" your streak by editing old entries - Seamless local → cloud migration — start local, add sync later without losing anything It's MIT licensed and self-hostable. Would love your feedback!
