Privacy Policy for Offhours

1. What Data Is Processed and Stored

To provide time limits, downtime schedules, and usage charts, the Extension stores information locally on your device using standard Chrome APIs[cite: 1]:

A. Extension Settings & Configuration

• What is stored: Your custom domain rules, time limits, downtime schedules, sort preferences, and total usage view modes[cite: 1].
• Where it is stored: chrome.storage.sync[cite: 1].
• How it is used: Saved configuration syncs across Chrome browsers where you are signed in with the same Google Account[cite: 1]. This data is strictly managed by Google Chrome and is never sent to us[cite: 1].

B. Usage History

• What is stored: The time spent (in seconds) on websites visited while using Chrome[cite: 1].
• Where it is stored: chrome.storage.local on your local device[cite: 1].
• Data Minimization & Compaction:
  • Detailed History: Exact per-domain usage is kept for the current day to enforce limits[cite: 1].
  • Historical Compaction: At the end of each day, usage for non-configured websites is aggregated into a single generic bucket (__other)[cite: 1]. The specific domains of unconfigured sites you visited on previous days are permanently discarded[cite: 1].
  • Retention: Usage history is stored for a maximum of 3,700 days (~10 years) to power your local usage charts and is subject to an automatic local storage cap of 8 MB (evicting oldest records first)[cite: 1].

C. Temporary Session Data

• What is stored: Temporary states such as active "Snooze" durations[cite: 1].
• Where it is stored: chrome.storage.session[cite: 1].
• How it is used: This data is ephemeral and is cleared automatically when the browser restarts[cite: 1].

2. Remote Servers & Analytics

• No External Servers: Offhours does not operate external databases, analytical servers, or tracking endpoints[cite: 1].
• No Telemetry / No Tracking: We do not track which sites you visit, how long you use the extension, or your personal identification details[cite: 1].
• No Third-Party Advertising: We do not display ads, sell data, or integrate third-party ad networks[cite: 1].

3. Data Export and Portability

You own your data[cite: 1]. You can export your full local usage history at any time as a .csv file via the Export data option located on the extension's Options page[cite: 1].

4. How to Delete Your Data

Because all data resides locally on your browser:

• Removing a site: Deleting a configured site from your settings clears its distinct historical data during the next daily compaction[cite: 1].
• Uninstalling the extension: Uninstalling Offhours instantly deletes all local storage, settings, and browsing history managed by the extension[cite: 1].
• Clearing browser data: You can also manually clear extension storage through Chrome's native developer tools or site data settings[cite: 1].

5. Permissions Justification

Offhours requests permissions through the Chrome Extension Manifest solely to fulfill its core features[cite: 1]:

• storage: Used to save your options and local time usage records[cite: 1].
• idle: Used to pause active time tracking when you are away from your computer[cite: 1].
• alarms: Used to trigger daily background maintenance (such as resetting daily limits at midnight and compacting history)[cite: 1].
• tabs / webNavigation / Active Tab Access: Used to detect the current domain, display time remaining on the extension badge, and redirect blocked tabs to the block page[cite: 1].

6. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect updates to the extension. Any updates will be reflected with a revised "Effective Date" at the top of this page.
