Show HN: Ichinichi – One note per day, E2E encrypted, local-first

Ichinichi is a minimalist, local-first journaling app that allows one note per day, with no ability to edit past entries, and features end-to-end encryption.

Look, every journaling app out there wants you to organize things into folders and tags and templates. I just wanted to write something down every day.

So I built this. One note per day. That's the whole deal.

Can't edit yesterday. What's done is done. Keeps you from fussing over old entries instead of writing today's.
Year view with dots showing which days you actually wrote. It's a streak chart. Works better than it should.
No signup required. Opens right up, stores everything locally in your browser. Optional cloud sync if you want it
E2E encrypted with AES-GCM, zero-knowledge, the whole nine yards.

Tech-wise: React, TypeScript, Vite, Zustand, IndexedDB. Supabase for optional sync. Deployed on Cloudflare. PWA-capable.

The name means "one day" in Japanese (いちにち).

The read-only past turned out to be the thing that actually made me stick with it. Can't waste time perfecting yesterday if yesterday won't let you in.
