Focus Lock - Privacy Policy

Focus Lock is designed from the ground up with a privacy-first, local-first philosophy. We believe your attention patterns and browsing data should remain entirely yours.

Below is a plain-English, jargon-free explanation of how Focus Lock handles your data.

1. What Data Focus Lock Collects & Stores

Focus Lock stores only the minimum data required to run your focus sessions and generate insights:

Preferences & Settings: Your active theme (light/dark), data retention period, auto-resume settings, and YouTube Focus Filters.
Workspace Configurations: Customized whitelist domains and configurations you define.
Focus Sessions: Timestamps, custom durations, reflection notes, and outcomes (e.g. "Succeeded", "Bypassed").
Attention Analytics: Domain names visited during focus sessions and transition tallies (e.g., navigating from github.com to chatgpt.com).

All information is stored locally on your device.

2. Where Your Data is Stored

100% Local: All stored data is saved directly on your local device.
Storage Engines: We use Chrome Storage (chrome.storage.local) for settings and preferences, and browser-secured IndexedDB for focus session logs and transition graphs.
No Cloud / No Servers: We do not run any cloud servers, databases, or analytics engines. Your data never leaves your device.

3. Data Deletion & Portability

Reset Data: You can clear all logs, analytics, and settings instantly via the "Reset" button inside the Focus Lock Settings panel.
Uninstall: Uninstalling the extension completely deletes all local storage and IndexedDB data associated with Focus Lock.
Data Portability: You can export a zip file backup of your settings and history at any time. Backup exports are created only when initiated by the user.

4. Why We Request Specific Permissions

Focus Lock requests browser permissions only to provide its core functionality:

storage: Needed to save your local configurations, whitelists, and daily statistics.
tabs: Used to identify the active tab's URL to check if it matches your workspace rules.
webNavigation: Used to intercept blocked pages before they load, redirecting you to your intentional reflection page.
alarms: Powers your focus timer and measures whitelisted bypass durations.
notifications: Displays a system alert when a focus session completes.
scripting: Injects a calming green focus ring overlay on allowed tabs to remind you of your target task.
idle: Detects if your computer screen is locked so focus tracking pauses automatically.

Host permissions are used solely to provide Focus Lock's core functionality, including workspace enforcement, voluntary website restrictions, and visual focus overlays on websites chosen by the user.

These permissions are never used to collect browsing history, monitor activity outside the extension's intended functionality, or transmit browsing data to external services.

5. Third-Party Services & Telemetry

0 Trackers: Focus Lock contains no analytical trackers, Google Analytics, or external logging tools.
0 Network Requests: Focus Lock makes zero outbound network requests to any server. All calculations (directed graphs, scorecards, narrative summaries) are computed locally.
