If you’re interested, I’m building something similar. Just published a working MVP at https://bearli.app

Polish level is low so far but:

    - works without sign-up
    - local-first (if you don’t sign up, no data ever leaves your device)
    - end-to-end encryption if you do decide to sign up

Not implemented yet, but planned:

    - proper PWA functionality (install to Home Screen, push notifications)
    - sharing kids with other users, etc.

Building primarily for personal use, but happy to hear feedback/suggestions/complaints (will add some in-app contact channels soon).
