If you do not agree to these Terms, you must immediately uninstall the Extension and discontinue all use.

The Extension does not require account creation, registration, or login. There is no username, password, or profile associated with your use of the Extension.

We reserve the right to take appropriate action in response to violations of these Terms, which may include restricting access to the Extension through Chrome Web Store mechanisms or pursuing legal remedies.
The Extension, including its software, design, logos, trademarks, service marks, icons, user interface, and user experience design, is owned by the Developer and is protected by applicable intellectual property laws. All rights not expressly granted in these Terms are reserved.
Portions of the Extension's source code may be made available on GitHub (https://github.com/YouJaeBeom/clutio) under applicable open-source licenses. Your use of such source code is governed by the terms of the applicable open-source license, and nothing in these Terms restricts your rights under such licenses.
You retain all rights to the vocabulary data you create using the Extension (saved words, notes, and similar user-generated content). We claim no ownership of or rights to your data.
The intellectual property rights in content generated by AI APIs (translations, definitions, example sentences, etc.) are subject to the terms of service of the respective AI service provider. We do not claim any rights to AI-generated content.
We respect the intellectual property rights of others. If you believe that any content accessible through the Extension infringes your copyright, you may submit a notification pursuant to the Digital Millennium Copyright Act (DMCA) by providing the following information in writing to contact@clutio.com:
Please note: Because the Extension operates entirely locally on users' devices and we do not host or control user-generated content on any server, our ability to remove specific content is limited. We will, however, address any claims relating to the Extension's own code and materials.
The Extension integrates with the following third-party AI services to provide translation functionality:
When you use the translation feature, the following data is transmitted to your selected AI service provider via HTTPS-encrypted communication:
This transmission occurs only when you actively request a translation. No data is transmitted without your explicit action.
Your use of third-party AI services is governed by the respective service provider's terms of service and privacy policy. You are solely responsible for reviewing and complying with those terms. We are not a party to any agreement between you and any third-party AI service provider.
We do not endorse, warrant, or assume responsibility for any third-party AI service, its availability, performance, output accuracy, or compliance with applicable laws.
Content generated by AI APIs (translations, definitions, example sentences, etc.) is produced automatically by machine learning models. Such content may be inaccurate, incomplete, misleading, biased, or otherwise flawed. You acknowledge that:

These Terms shall be governed by and construed in accordance with the laws of the Republic of Korea, without regard to its conflict of law provisions. For Users located outside the Republic of Korea, mandatory consumer protection laws of your jurisdiction may also apply to the extent they provide greater protection.
Before initiating any formal dispute resolution proceeding, you agree to first contact us at contact@clutio.com and attempt to resolve the dispute informally for at least 30 days.
For Users located outside the Republic of Korea: Any dispute, controversy, or claim arising out of or relating to these Terms or the Extension that cannot be resolved informally shall be finally settled by binding arbitration administered by the Korean Commercial Arbitration Board (KCAB) under its International Arbitration Rules.

The arbitral award shall be final and binding and may be entered as a judgment in any court of competent jurisdiction.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, YOU AGREE THAT ANY DISPUTE RESOLUTION PROCEEDINGS WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION.

Nothing in this Section prevents either party from seeking injunctive or other equitable relief from a court of competent jurisdiction to prevent the actual or threatened infringement, misappropriation, or violation of intellectual property rights or confidential information.
If any provision of these Terms is held by a court or arbitrator of competent jurisdiction to be invalid, illegal, or unenforceable, such provision shall be modified to the minimum extent necessary to make it valid, legal, and enforceable. If such modification is not possible, the provision shall be severed from these Terms. The invalidity or unenforceability of any provision shall not affect the validity or enforceability of the remaining provisions, which shall continue in full force and effect.
These Terms, together with the Privacy Policy, constitute the entire agreement between you and the Developer regarding your use of the Extension, and supersede all prior and contemporaneous understandings, agreements, representations, and warranties, both written and oral.
The failure of the Developer to exercise or enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver must be in writing and signed by the Developer.
You may not assign or transfer your rights or obligations under these Terms without the prior written consent of the Developer. The Developer may assign its rights and obligations under these Terms without restriction.
The Developer shall not be liable for any failure to perform or delay in performing any obligation under these Terms to the extent that such failure or delay is caused by circumstances beyond its reasonable control, including but not limited to natural disasters, war, terrorism, riots, labor disputes, government actions, internet or telecommunications failures, or actions of third-party service providers.
Any notices required or permitted under these Terms may be sent to us at contact@clutio.com. We may provide notices to you through the Extension, our website, or Chrome Web Store listing.
The section headings in these Terms are for convenience only and have no legal or contractual effect.
