Terms of Service

1. Eligibility

You must be at least 13 years old (or the minimum age required in your jurisdiction) to use LingoLens. If you are under 18, you represent that a parent or legal guardian has reviewed and agreed to these Terms on your behalf. By using the Service, you represent and warrant that you meet these eligibility requirements.

2. Account Registration

To access most features of LingoLens, you must create an account. You agree to provide accurate, current, and complete information during registration and to keep your account information up to date. You are solely responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account. You must notify us immediately if you suspect unauthorized access to your account. We reserve the right to suspend or terminate accounts that contain false or misleading information.

3. The Service

LingoLens provides language-learning tools that work alongside YouTube content, including real-time subtitle translation, interactive word tracking, vocabulary management, flashcard study, and progress analytics. The Service includes both the browser extension and the web dashboard. LingoLens does not host, stream, or redistribute any YouTube content. The extension operates as an overlay within your browser while you watch videos on YouTube.

4. Subscriptions and Payments

4.1 Free and Paid Plans

LingoLens offers both free and paid subscription plans. Features available on each plan are described on our pricing page and may change over time. We will notify existing subscribers before removing features from their current plan.

4.2 Billing

Paid subscriptions are billed in advance on a recurring basis (monthly or annually, depending on the plan you select). By subscribing, you authorize us to charge your payment method at the applicable rate. All payments are processed securely through Stripe. Prices are displayed in US dollars unless otherwise noted and are exclusive of applicable taxes.

4.3 Automatic Renewal

Your subscription will automatically renew at the end of each billing cycle unless you cancel before the renewal date. You can cancel your subscription at any time from your account settings. Cancellation takes effect at the end of the current billing period, and you will retain access to paid features until that date.

4.4 Refunds

Payments are generally non-refundable. However, if you experience a technical issue that prevents you from using the Service, or if you cancel within 48 hours of your initial subscription purchase, you may request a refund by contacting us. Refund requests are reviewed on a case-by-case basis. We reserve the right to deny refund requests that we determine to be abusive or fraudulent.

4.5 Price Changes

We may change subscription prices from time to time. If we increase prices, we will provide at least 30 days' notice before the change takes effect. The new price will apply at your next renewal date. If you do not agree to the price change, you may cancel your subscription before the renewal.

5. Acceptable Use

You agree to use the Service in compliance with all applicable laws and our Acceptable Use Policy. Without limiting the foregoing, you agree not to:

• Reverse engineer, decompile, or disassemble any part of the Service
• Attempt to gain unauthorized access to our systems, other user accounts, or data
• Use automated tools (bots, scrapers, crawlers) to access the Service except through our published APIs
• Interfere with or disrupt the integrity or performance of the Service
• Use the Service to violate intellectual property rights of others
• Resell, sublicense, or redistribute access to the Service without our written permission
• Create multiple free accounts to circumvent usage limits

6. Your Content and Data

6.1 Ownership

You retain all rights to the content you create within LingoLens, including your word bank entries, notes, and custom study data.

6.2 License to Us

You grant LingoLens a limited, non-exclusive, worldwide, royalty-free license to process, store, and display your content solely for the purpose of providing and improving the Service. This license terminates when you delete your content or account.

6.3 Data Portability

You may export your learning data at any time through the dashboard. Exported data is provided in standard formats for your convenience.

7. Intellectual Property

The LingoLens name, logo, website design, software, and all related materials are owned by LingoLens and protected by copyright, trademark, and other intellectual property laws. Nothing in these Terms grants you any right to use our branding, trademarks, or proprietary materials without our prior written consent. The Service may include open-source components governed by their respective licenses.

8. Third-Party Services

LingoLens integrates with and relies on third-party services including YouTube (for video content and subtitles), Stripe (for payment processing), and translation/dictionary APIs. Your use of these services is subject to their respective terms and policies. We are not responsible for the availability, accuracy, or practices of any third-party service. LingoLens is not affiliated with, endorsed by, or sponsored by YouTube or Google.

9. Service Availability and Changes

We strive to keep LingoLens available and reliable, but we do not guarantee uninterrupted or error-free operation. We may modify, suspend, or discontinue any part of the Service at any time for maintenance, security, legal compliance, or business reasons. We will provide reasonable advance notice when changes materially affect your use of the Service. If we discontinue the Service entirely, we will provide at least 30 days' notice and an opportunity to export your data.

10. Termination

10.1 By You

You may stop using LingoLens and delete your account at any time from your account settings. Upon deletion, we will remove your personal data in accordance with our Privacy Policy.

10.2 By Us

We may suspend or terminate your access to the Service if we reasonably believe you have violated these Terms or our Acceptable Use Policy, if your use poses a security risk to the Service or other users, or if required by law. Where possible, we will provide notice and an explanation before or at the time of suspension. In cases of severe or repeated violations, we may terminate without prior notice.

10.3 Effect of Termination

Upon termination, your right to use the Service ceases immediately. Sections of these Terms that by their nature should survive termination will remain in effect, including provisions relating to intellectual property, limitation of liability, indemnification, and dispute resolution.

11. Disclaimers

The Service is provided on an "as is" and "as available" basis without warranties of any kind, whether express, implied, or statutory, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. LingoLens does not warrant that the Service will be uninterrupted, timely, secure, or error-free, or that translations and definitions provided through the Service will be accurate or complete. You acknowledge that language learning results may vary and depend on your individual effort and engagement.

12. Limitation of Liability

To the maximum extent permitted by applicable law, LingoLens and its officers, directors, employees, and agents shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or goodwill, arising out of or related to your use of the Service, regardless of the theory of liability. Our total aggregate liability for all claims arising from or related to these Terms or the Service shall not exceed the amount you paid to LingoLens in the twelve (12) months preceding the event giving rise to the claim, or one hundred US dollars ($100), whichever is greater.

13. Indemnification

You agree to indemnify, defend, and hold harmless LingoLens and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to your violation of these Terms, your misuse of the Service, or your violation of any third-party rights.

14. Dispute Resolution

If a dispute arises from these Terms or the Service, you agree to first attempt to resolve it informally by contacting us. If the dispute cannot be resolved within 30 days, either party may pursue resolution through binding arbitration administered under the rules of the American Arbitration Association, conducted in English. You agree that any dispute resolution proceedings will be conducted on an individual basis and not as part of a class, consolidated, or representative action.

15. Governing Law

These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of law provisions. Any legal action not subject to arbitration shall be brought in the federal or state courts located in Delaware.

16. General Provisions

• Entire Agreement: These Terms, together with our Privacy Policy, Cookie Policy, and Acceptable Use Policy, constitute the entire agreement between you and LingoLens regarding the Service.
• Severability: If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force and effect.
• Waiver: Our failure to enforce any right or provision of these Terms will not constitute a waiver of that right or provision.
• Assignment: You may not assign or transfer these Terms without our consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.
• Force Majeure: We are not liable for failures or delays caused by circumstances beyond our reasonable control, including natural disasters, war, government actions, or internet outages.

17. Changes to These Terms

We may update these Terms from time to time. When we make material changes, we will update the "Last updated" date at the top of this page and notify you by email or through the Service at least 15 days before the changes take effect.
