Privacy Policy

Last updated: July 07, 2026

This Privacy Policy describes how the HD ROLS Chrome extension ("the Extension") handles your information when you use it.

1. Overview

The Extension is a productivity tool designed exclusively for authorized employees working with the internal service at hd.crystals.ru. It provides quick filters, theme customization, and local history management.

2. Information Collected

The Extension processes the following types of information:

• Action history — retrieved from the hd.crystals.ru API using your existing session credentials. This data is stored locally in your browser via chrome.storage.local.
• User preferences — such as theme selection and filter settings. Stored locally in chrome.storage.local.

3. How Information Is Used

• Action history is used solely to display past records within the Extension popup and to allow the user to copy them to the clipboard.
• Preferences are used to apply the user's chosen settings when visiting hd.crystals.ru.

4. Data Transmission

The Extension does not transmit any user data to external servers, third parties, or the Extension developer. All network requests made by the Extension are directed exclusively to hd.crystals.ru and use the user's existing authentication cookies — no additional credentials are collected or sent.

5. Data Storage and Retention

• All data is stored locally on the user's device using chrome.storage.local.
• Saved action history is automatically deleted after 30 days.
• The user can manually delete all stored data at any time through Chrome's extension settings or by uninstalling the Extension.

6. Permissions Used

• storage — to save user preferences and history locally.
• host permission for hd.crystals.ru — to interact with the internal service the user is authorized to access.

7. Third-Party Services

The Extension does not integrate with any third-party services, analytics, advertising networks, or external APIs.

8. Children's Privacy

The Extension is intended for use by authorized adult employees only and is not directed to children under the age of 13.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
