Privacy Policy for "Close on Back" Chrome Extension

This Privacy Policy describes how the "Close on Back" Chrome Extension (hereinafter, "the Extension") processes information. The Extension is designed to provide a specific navigation functionality in your browser and does not collect any personally identifiable information about you.

What Information Does the Extension Collect?

The Extension collects and processes the following types of information:

• Browse History (URLs): The Extension reads the URL of the tabs you visit to apply its "Close on Back" functionality. This involves checking the URL to determine if it starts with https:// and performing internal history manipulation (e.g., adding a #closeonback hash). This URL information is processed only locally within your browser and is neither stored nor transmitted to external servers.
• Extension State: The Extension locally stores your preference regarding whether the "Close on Back" functionality is active or inactive. This setting is saved via chrome.storage.sync, meaning it will synchronize across your Chrome installations if you're logged in with the same Google account. This information is purely functional and contains no personal data.

How Is Information Used?

The collected information is used solely for the following purpose:

• To provide the Extension's functionality: The URL information is essential to determine when and how to manipulate the browser history to enable the "Close on Back" feature. The Extension's state (isActive) is used to enable or disable the Extension's functionality based on your preference.

Is Information Shared with Third Parties?

No, the "Close on Back" Extension does not share any information with third parties. All data processing occurs entirely locally within your browser. No data is transmitted to external servers, including those of the developer.

How Is Information Secured?

Since the Extension does not collect personally identifiable information or transmit it to external servers, the risks related to data security are minimal. All information used by the Extension (such as URLs for processing purposes and your active/inactive preference) remains stored locally in your browser and is subject to Chrome's own security measures.

Data Retention

Information (such as the isActive status and temporary URL references in browser history) is retained for as long as the Extension is installed in your browser. When the Extension is uninstalled, all locally stored data related to the Extension will be cleared.

Changes to This Privacy Policy

This Privacy Policy may be updated from time to time. We encourage you to review this policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
