Screen Time Tracker

Windows desktop tracker for active computer time, focused on study discipline and daily limits.

The app tracks only active time, pauses after idle time, supports exact browser-domain classification, runs in tray, and helps enforce limits for:

• total computer time
• study
• browser fun / manga / manhwa
• social media

Default limits:

• total: 3h
• study target: 2h to 2.5h
• browser fun: 30m
• socials: 18m

Highlights

• Active-time tracking instead of simple PC uptime
• Idle detection
• Silent launcher EXE builder for cleaner startup
• Rules by process, window title, URL, or domain
• Custom categories mapped to built-in parent categories
• Review screen for uncategorized activity
• Health screen with rule suggestions
• Weekly review and calendar heatmap
• Focus mode and hard block mode
• Tray controls and quick glance mini window
• Per-day storage with summary cache for better performance
• CSV / JSON export

Tech Stack

Project Structure

• launcher/ScreenTimeTrackerLauncher.cs - source for the silent EXE launcher
• scripts/build-launcher.ps1 - builds ScreenTimeTracker.exe
• ScreenTimeTracker.exe - generated silent launcher without console window
• start-tracker.vbs - legacy fallback launcher
• start-tracker.bat - convenience launcher
• settings.json - default settings
• rules.json - built-in classification rules
• browser-extension/ - unpacked Chromium extension for exact site tracking
• Image/ - application icon assets
• docs/screenshots/ - GitHub screenshots
• data/ - runtime data, logs, caches, exports, backups

Quick Start

From a GitHub checkout:

1. Build the launcher:

powershell -ExecutionPolicy Bypass -File .\scripts\build-launcher.ps1

2. Double-click ScreenTimeTracker.exe
3. Open the tray icon if the window starts minimized
4. Adjust limits in Settings
5. Refine classification through Rules, Categories, Review, and Health

Fallback if you do not want to build the launcher:

• Double-click start-tracker.vbs
• Or run start-tracker.bat

Build a portable release archive:

powershell -ExecutionPolicy Bypass -File .\scripts\package-release.ps1 -Version v0.1.0

Manual run from terminal:

powershell -ExecutionPolicy Bypass -File .\ScreenTimeTracker.ps1

Run self-test:

powershell -NoProfile -ExecutionPolicy Bypass -File .\ScreenTimeTracker.ps1 -SelfTest

Browser Extension

To classify browser activity by exact domain instead of only the tab title:

1. Open edge://extensions or chrome://extensions
2. Turn on Developer mode
3. Click Load unpacked
4. Select the browser-extension folder

The extension sends active-tab data to 127.0.0.1:38945.

Quick Glance

Main Screens

• Today - top activities, apps, and categories for the current day
• History - recent daily totals
• Insights - compact weekly overview
• Week review - slipped days, top distractions, and heatmap
• Goals - progress toward daily limits and study target
• Analytics - charts, streaks, and exports
• Timeline - hourly activity and session view
• Review - uncategorized items to fix
• Health - classification coverage and suggested rules
• Rules - loaded rule set

Customization

Built-in parent categories stay fixed:

• study
• browser_fun
• socials
• other

You can add your own categories under those parents from the app. This keeps limits and dashboards stable while allowing more detailed classification.

You can edit:

• Settings
• Categories
• Rules
• Classify current

You can also edit settings.json and rules.json manually if you want.

Data and Privacy

All data is stored locally.

Runtime files are written under data/, including:

• per-day usage files
• browser bridge cache
• summary cache
• exports
• backups
• startup logs

These runtime files are ignored by git and should normally not be committed.

Performance Notes

The app already includes:

• per-day storage instead of one huge JSON file
• summary cache for history and analytics
• lighter background refresh behavior
• tray-first workflow

Repository Notes

• This repository is intended for Windows users
• No external package installation is required
• ScreenTimeTracker.exe is generated locally and is not committed
• portable release archives are generated locally under release/
• Runtime data is generated automatically on first run
• License: MIT
