Privacy Policy for Tab History Navigator

Last Updated: February 12, 2026

Overview

Tab History Navigator is a Chrome extension that enables browser-like back/forward navigation through your tab history. We are committed to protecting your privacy and being transparent about our data practices.

Key Points:

  • Tab history is stored locally on your device only
  • Anonymous usage analytics can be completely disabled
  • We do not collect personally identifiable information
  • We do not sell or share your data with third parties

Information We Collect

1. Local Tab History

The extension stores your tab navigation history locally in your browser’s storage. This includes:

  • Tab IDs (internal Chrome identifiers)
  • Navigation position in your history
  • Timestamp of last cleanup operation

Storage: This data is stored locally using Chrome’s storage API and never leaves your device except as described in the Analytics section below.

Retention: History is limited to your last 60 tab visits and is automatically cleaned up. Data is deleted when you uninstall the extension.

2. Anonymous Usage Analytics (Optional)

We use PostHog analytics to understand how users interact with the extension. This helps us improve features and fix bugs.

What we collect:

  • Extension events (e.g., “navigated back”, “navigated forward”)
  • Anonymous session identifiers
  • Browser type and extension version
  • General error information (no personal data)

What we DO NOT collect:

  • URLs you visit
  • Tab titles or content
  • Personally identifiable information
  • IP addresses (anonymized by PostHog)

Note: The current version does not include a user-facing option to disable analytics. If you prefer to use the extension without analytics, you can build it from source and disable analytics by editing src/analytics-config.js. See the GitHub repository for build instructions.

How We Use Information

  • Tab History: To provide back/forward navigation functionality
  • Analytics: To understand feature usage, identify bugs, and improve the extension

Data Sharing and Third Parties

We do not sell, trade, or share your data with third parties, except:

  • PostHog: Anonymous analytics data is sent to PostHog (us.i.posthog.com) for usage analysis. PostHog’s privacy policy: https://posthog.com/privacy

Data Security

Tab history is stored locally using Chrome’s secure storage API. Analytics data transmitted to PostHog uses HTTPS encryption.

Your Rights

You have the right to:

  • Access: View your locally stored tab history in Chrome DevTools (inspect extension background page)
  • Delete: Clear all data by uninstalling the extension or clearing Chrome’s extension storage
  • Opt-out: Disable analytics as described above

Children’s Privacy

This extension does not knowingly collect information from children under 13. The extension is not directed at children.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated “Last Updated” date.
