Privacy Policy for Cyrillic Killer

Last Updated: January 1, 2026

Introduction

Cyrillic Killer ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how our browser extension handles information when you use it.

Data Collection and Storage

Cyrillic Killer does not collect, transmit, or store any personal information or user data on external servers.

The extension operates entirely locally on your device. The only data stored is:

  • Site Exception List: A list of website domains that you choose to exclude from Cyrillic character blurring. This list is stored locally in your browser's storage using Chrome's storage API.
  • Extension Preferences: Your personal settings and preferences for the extension, which are stored locally in your browser.

All stored data remains on your device and is never transmitted to any external server, third-party service, or our servers.

How We Use Information

The extension uses locally stored data solely for the following purposes:

  • To remember which websites you have excluded from Cyrillic character blurring
  • To maintain your extension preferences and settings
  • To provide the core functionality of blurring Cyrillic characters on web pages

Permissions Used

Cyrillic Killer requires the following permissions:

  • Storage: Used to store your site exception list and preferences locally on your device.
  • ActiveTab: Used to access the current tab's content to detect and blur Cyrillic characters.

The extension only accesses the content of tabs when you are actively viewing them. It does not access tabs in the background or when they are not active.

Third-Party Services

Cyrillic Killer does not use any third-party services, analytics tools, tracking scripts, or external APIs. The extension operates completely independently and does not communicate with any external servers.

Data Security

Since all data is stored locally on your device using your browser's built-in storage mechanisms, your data is protected by your browser's security features. We do not have access to your stored data, and it cannot be accessed by external parties through our extension.

Data Deletion

You can delete all data associated with Cyrillic Killer at any time by:

  • Uninstalling the extension from your browser
  • Clearing your browser's extension storage data through your browser's settings
  • Manually removing sites from the exception list through the extension's popup interface

Children's Privacy

Cyrillic Killer is not directed to children under the age of 13. We do not knowingly collect personal information from children. Since we do not collect any personal information, this policy applies to all users regardless of age.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date at the top of this policy.
