About · ClarityHub

Quick Summary

This app lives only inside your browser window, and it sends no data to the internet. It's grounded, not in the cloud.

It helps you write notes, plan your tasks, see your calendar, and keep a daily journal — all in one page, without the internet.

Local-first: Everything saved in your browser.
No Cloud: No accounts, no telemetry, no remote calls.
Modules: Notes & Files, Matrix, Calendar, Journal.
Backups: One-click export and restore.
Needs: Chrome, Brave, Edge, or Arc (desktop) for full file access.

💡 Clearing cookies or site data erases the app’s saved state. Make sure you have used Backup before clearing.

What It Is

ClarityHub is a small helper that runs inside your browser. It has four tools: one for writing, one for sorting work, one for seeing your days, and one for journaling. It never sends your data anywhere — it keeps it inside your computer.

How It Works (simple view)

You open the App.
The page becomes a control room with four buttons on top.
You click the tab you need — Notes, Matrix, Calendar, or Journal.
You do your work, and save it.

Browser support

Chromium (desktop): Full File System Access (connect folders, open/save, autosave). Speech input is optional.
Firefox/Safari: Limited mode. Notes open via file picker and save via “Download .md”. Files left panel is hidden.
Mobile (iOS/Android): Works in limited mode. No directory access.

Important: If you clear browser cookies or site data, your saved tasks, events, and journal disappear. Always press Backup to save a copy (.json) before clearing anything.

Notes & Files

This is like your notebook shelf.

Click + Connect Folder → choose a folder on your computer (Chromium desktop).
Open, read, and edit .md or .txt files inside it. Make new files or rename existing ones.
Use Ctrl + S to save. Autosave also runs after edits.
Type on the left and see live Markdown preview on the right: headings, bold/italic/strike, lists, quotes, code blocks, links.
Outline pane lists your headings. Drag any heading to reorder that whole section in the document.
Export PDF uses your browser’s print-to-PDF.
Dictation is available where supported (WebKit speech).
In limited mode, use Open (file picker) and Download .md to save.

The Eisenhower Matrix

Sort your chores into four boxes:

Do now — urgent + important.
Plan — not urgent + important.
Delegate — urgent + not important.
Ignore — neither urgent nor important.

Click inside any box to add a task. Set a due date or mark it done with ✓. Done tasks fade and drop. Everything persists locally.

Calendar

Month grid with simple events.

Use ◀ or ▶ to move between months. Today jumps back.
Add events with title, date, time, and notes.
Repeat options: daily ×10 or weekly ×10.
Edit or delete by clicking an event badge.
Export/import calendar via .ics.

Journal

A diary per date. Pick a day, write in Markdown, and it stays saved for that date.

Pick a day with the date picker.
Write using Markdown. Optional side-by-side preview.
Click Save when done. Entries are stored locally.

Backup and Restore

Press Backup → downloads ps_backup_YYYY-MM-DD.json.
Keep that file safe — it includes tasks, events, and journal.
To restore, press Restore and select that file.

What Stays Safe When You Clear Cookies

Your actual files and folders on disk stay safe.
App memory (tasks, journal, calendar) vanishes unless you backed it up.
You’ll reconnect folders next time.

Limitations (the fine print)

Full file features require desktop Chromium (Chrome, Edge, Arc, Brave). Firefox/Safari run in limited mode.
No online sync or multi-device storage.
Calendar repeats limited to daily ×10 or weekly ×10.
Markdown renderer is minimal: no tables, no syntax highlighting.
No global search yet.
Backups are plain JSON, unencrypted. Treat them as private.

💡 Clearing cookies or site data erases the app’s saved state. Make sure you have used Backup before clearing.

More Notes

State is stored in localStorage and IndexedDB.
Folder access uses the File System Access API (where supported).
No telemetry, no network requests.
Single-file app, loads fast, works offline after first load.

Privacy & data

No servers, no tracking. Logic runs client-side.
Back up or migrate using Backup/Restore in the header.
In limited mode, use “Open” (file picker) and “Download .md” to save.
