ClarityHub

A local-first productivity hub

Notes, tasks, calendar, and journal — all running entirely in your browser.
No server, no telemetry, no cloud dependencies.
Your data remains only on your device.

Browser support:
Full features on Chromium (Chrome, Edge, Arc) over HTTPS.
Firefox/Safari run in limited mode: notes work via import/download.

All work and no play makes Jack a dull boy. Need a break? Check out ClarityToybox!
But if you do feel like working some more, you might like ClarityForge too.
