Please read these Terms of Service ("Terms") carefully before using YT1s (the "Service"). By accessing or using the Service, you agree to be bound by these Terms. If you do not agree, please do not use the Service.

1. Eligibility

You must be at least 13 years old to use the Service. By using YT1s, you confirm that you meet this requirement and that your use of the Service complies with all laws applicable to you.

2. Description of Service

YT1s is a free online tool that lets you search for YouTube videos and convert them into formats such as MP3, MP4, 3GP, WEBM, and M4A for personal, offline use. The Service does not require registration or an account. We may add, change, or remove features of the Service at any time without notice.

3. Acceptable Use

You agree to use the Service only for lawful purposes. In particular, you agree not to:

• Use the Service to download or distribute content that infringes someone else's copyright or other intellectual property rights;
• Use automated tools, bots, or scripts to access the Service in a way that places excessive load on our systems;
• Attempt to interfere with, disrupt, or gain unauthorized access to the Service or its underlying infrastructure;
• Use the Service for any commercial redistribution of downloaded content without the rights holder's permission;
• Reverse engineer, decompile, or otherwise attempt to extract the source code of the Service.

You are solely responsible for making sure you have the right to download and use any content you access through the Service. YT1s does not host, store, or claim ownership of any video or audio content; it acts only as a conversion tool for content already publicly available on YouTube.

4. Copyright

We respect intellectual property rights and expect users of the Service to do the same. Downloading copyrighted content without the permission of the rights holder may violate the law in your jurisdiction — the Service should only be used to download content you own, that is in the public domain, or that you otherwise have permission to save. If you believe content accessible via the Service infringes your copyright, please contact us at support@yt1s.works with details of your claim.

5. No Account Required

YT1s does not require you to create an account to use the core features of the Service. Because of this, we do not maintain user profiles, passwords, or persistent identifiers tied to your identity.

6. Service "As Is"

The Service is provided "as is" and "as available," without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not guarantee that the Service will be uninterrupted, error-free, or available at all times.

7. Limitation of Liability

To the maximum extent permitted by law, YT1s and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, arising from your use of, or inability to use, the Service. Your use of the Service is at your own risk.

8. Third-Party Links and Content

The Service may reference or link to third-party websites, including YouTube, which are outside our control. We are not responsible for the content, policies, or practices of any third-party site, and linking to a site does not imply endorsement of it.

9. Termination

We reserve the right to suspend or restrict access to the Service, in whole or in part, for any user or IP address that we believe is violating these Terms, without prior notice.

10. Changes to These Terms

We may update these Terms from time to time. When we do, we will revise the "Last updated" date at the top of this page. Continuing to use the Service after changes take effect means you accept the revised Terms.

11. Governing Terms

These Terms constitute the entire agreement between you and YT1s regarding use of the Service and supersede any prior agreements. If any provision of these Terms is found to be unenforceable, the remaining provisions will remain in full effect.
