Terms of use

These terms apply when you visit blockchannel.one or install the Block YouTube Channels extension. Using either one means you accept them.

Last updated

Effective 10 November 2026.

1. Who provides the service

The website blockchannel.one and the Block YouTube Channels browser extension (together, the "Service") are provided by Captain Software Limited, Unit B, 11/F, 23 Thomson Road, Wan Chai, Hong Kong SAR China. "We" and "us" in these terms mean that company. If you do not agree with these terms, please do not use the Service.

2. Your license

The extension is free. We give you a personal, non-exclusive, non-transferable and revocable license to download, install and use it for your own non-commercial purposes under these terms. You may install it on as many of your own devices as you like.

You may not sell the extension, include it in a paid product, or publish modified copies under the name blockchannel.one or Block YouTube Channels.

3. Acceptable use

When you use the Service, you agree that you will not:

  • break any law that applies to you, or YouTube's own terms of service;
  • reverse-engineer the extension to build a product that misleads people about where it comes from, or strip notices out of it;
  • spread copies of the extension that contain malicious code or that collect data from the people who install them;
  • try to disrupt or overload the website or its server, or get into either without permission.

4. What the extension changes

The extension acts only on what your own browser displays. It hides items and adds buttons according to your settings. Your YouTube account, your recommendation history and everything stored on YouTube's servers stay as they were. YouTube can change its pages at any time, and a change on its side may stop some features from working until we release an update.

5. YouTube, Google and other names

Block YouTube Channels is an independent product. YouTube and Google LLC have not made, endorsed, sponsored or approved it, and we are not affiliated with them. YouTube, YouTube Shorts, YouTube Kids and YouTube TV are trademarks of Google LLC. Chrome, Edge, Brave, Opera, Firefox and other product names belong to their owners, and we mention them only to say where the extension works.

6. Price

The Service costs nothing today. Should we ever offer paid features, we will publish their price and terms on the website before they go on sale, together with the refund rules in our refund policy. We will not remove existing free features to push anyone into a purchase.

7. Updates and availability

We may change, pause or discontinue the Service or any part of it at any time, with or without notice. We are not obliged to release updates. Any update we do release falls under these terms.

8. Feedback

If you send us ideas or suggestions, we may use them to improve the Service, and we owe you nothing for doing so.

9. No warranty

We provide the Service "as is" and "as available", without any express or implied warranty, including warranties of fitness for a particular purpose, accuracy and non-infringement. We cannot promise that the extension will catch every matching item on YouTube, that it will run on every browser version, or that the Service will be free of errors and interruptions.

The extension is a convenience tool. It is no substitute for parental control or security software, so do not rely on it alone to keep content away from children.

10. Limitation of liability

As far as the law allows, Captain Software Limited and its staff are not liable for indirect, incidental, special, consequential or punitive damages, or for lost data, profit or goodwill, that result from using the Service or being unable to use it. For any claim about the Service, our total liability is capped at what you paid us for it in the twelve months before the claim. The Service is free, so that amount is zero.

These terms do not exclude any liability that the law says cannot be excluded, and they do not reduce the rights you have as a consumer under the mandatory laws of the country where you live.

11. Links to other sites

The website may link to sites run by others, such as browser help pages. We do not control those sites and are not responsible for their content or their privacy practices.

12. Ending your use

You can stop using the Service whenever you want by removing the extension. If you breach these terms, we may end your license. Sections 9, 10 and 13 continue to apply after your use ends.

13. Governing law

The laws of the Hong Kong Special Administrative Region govern these terms, and the courts of Hong Kong will hear any dispute. This does not affect mandatory consumer protection rules of the country where you live.

14. Changes to these terms

We may update these terms from time to time. This page always shows the current version and the date it was last updated. If you keep using the Service after a change, you accept the new version.
