To enable access to only specific websites while blocking all others, go to the Extra Configs section in the settings. Then, turn on the White List Mode option. Once enabled, only the websites listed in your Dashboard table will be accessible — all other websites will be blocked by default.
Unfortunately, it is not possible to completely prevent the extension from being removed. This is due to Chrome's extension policy, which does not allow any extension to block or restrict its own uninstallation.
This policy is in place to ensure that users maintain full control over their browser and extensions. While this may seem like a limitation, it is a deliberate security measure by Chrome to prevent malicious behavior from extensions.
However, if you are using this extension in a supervised environment (such as in schools or organizations), it is possible to manage extensions using Chrome Enterprise policies or third-party management tools to restrict removal or modification through administrative controls.
The extension uses Chrome's localStorage to save your settings and configurations. This means all data is stored locally on your device and is not uploaded or synced to the cloud by default.
If you want to use the same settings on another PC or browser, you can manually export your data using the Sync option available in the extension. This allows you to back up or transfer your configurations easily and securely.

If you want to block only specific parts or sections of a website (rather than the entire domain), you can use the Blocks By Keys option. Simply enter a keyword or a partial URL, and any webpage that contains that keyword in its URL will be blocked automatically.
Alternatively, you can use the Rules feature to create more advanced blocking conditions. This allows you to precisely target specific paths or parameters in URLs for greater control.
