Arc Interpreter Terms of Service

1. Acceptance of Terms

By downloading, installing, or using Arc Interpreter (the "App"), you confirm that you have fully read, understood, and agreed to all of these Terms. If you do not agree, do not use the App.

If you are under the age of 14 (in mainland China) or under the legal age in your jurisdiction, do not use the App.

2. Description of Service

The App is an AI-powered real-time voice translation tool, with the following features:

• Cross-language real-time voice interpretation (primarily Chinese ↔ English);
• Pre-meeting brief preparation (web-search-based meeting context);
• Post-meeting translation summary, key-point extraction, and participant profile generation;
• Bluetooth communication with paired smart-glasses hardware.

The App is currently in MVP (Minimum Viable Product) stage and is provided free of charge.

3. Important Disclaimer — Translation Accuracy

⚠️ Arc Interpreter provides AI-automated translation. It is NOT a substitute for professional human interpretation.

You acknowledge and accept the following:

• The App uses third-party AI models for translation; results may contain errors, omissions, inaccuracies, or cultural-context distortions;
• For high-stakes contexts — including but not limited to legal, medical, financial, government, contract negotiation, immigration, and critical medical diagnosis — engage a certified professional human interpreter;
• Any consequences arising from your reliance on the App's translation output (including but not limited to commercial loss, legal disputes, medical misjudgment, property damage, or personal injury) are your sole responsibility;
• We make no express or implied warranty as to translation quality, accuracy, completeness, or timeliness;
• We are not responsible for the output of third-party AI services.

4. User Conduct

You agree NOT to:

• Illegal use: translate content related to illegal activities, terrorism, threats to national security, or threats to public order;
• Infringement: record conversations in violation of recording-consent laws applicable in your or the other parties' location; translate content that infringes others' privacy, likeness, reputation, or intellectual property rights;
• Misuse: reverse-engineer, decompile, modify, or tamper with the App; circumvent the App's usage limits, rate limits, or security mechanisms;
• Commercial abuse: resell or redistribute the App; provide translation services to third parties using the App as backend;
• Service interference: attack our servers, third-party APIs, or interfere with other users' normal use;
• Resource abuse: invoke the App's services through automated scripts, bots, or scrapers in bulk.

Violation of any provision above gives us the right to immediately terminate your access and pursue legal remedies.

5. Recording Compliance

⚠️ You are responsible for understanding and complying with the recording-consent laws of your jurisdiction and the jurisdictions of all conversation participants.

Notes:

• Some jurisdictions (e.g., California, Illinois, Florida in the US, and many EU member states) require all-party consent before recording a conversation;
• Mainland China generally permits one-party-consent recording (your own consent suffices), but recordings used for litigation evidence or commercial disclosure are subject to additional rules;
• Cross-border meetings may be subject to multiple jurisdictions' laws simultaneously — comply with the strictest applicable law.

The App is not responsible for the legality of your recording behavior.

6. Intellectual Property

6.1 The App

• All source code, trademarks, icons, visual design, UI copy, and product documentation of the App are owned by Hedy Song (宋慧雯);
• Without written permission, no party may copy, modify, distribute, or commercially use the above.

6.2 Your Content

• The meeting context you input, the meeting voice you produce, and the translation outputs generated — ownership remains with you;
• You grant us a limited, non-exclusive, temporary license solely to: complete translation tasks and operate App features. This license terminates when you uninstall the App or end the current session;
• We do not use your content for any other purpose (see the Privacy Policy).

6.3 Third-Party Processors

The third-party AI services (Deepgram, DeepSeek, Anthropic, Tavily) used by the App handle your content under their respective Terms of Service. Please review them.

7. Service Availability

• As an MVP-stage product, the App may contain bugs, instabilities, temporary outages, or feature changes;
• We reserve the right to modify, suspend, or terminate any feature at any time; in principle, material changes will be communicated in advance;
• We are not liable for losses arising from service interruption, network issues, third-party API failures, or device-compatibility issues;
• Service quality depends on your network conditions, device performance, and third-party-service availability.

8. Limitation of Liability

To the maximum extent permitted by applicable law:

• We are NOT liable for any direct, indirect, incidental, special, punitive, or consequential damages (including but not limited to lost profits, lost business opportunities, loss of goodwill, data loss, business interruption, or personal injury) arising from your use or inability to use the App;
• Our cumulative total liability shall not exceed the total amount you have paid us for use of the App in the past 12 months. As the App is currently free, this liability is zero;
• The above limitation applies regardless of any failure of essential remedy;
• If applicable law does not allow exclusion or limitation of certain damages, this section adjusts to the maximum permitted in that jurisdiction.

9. Termination

9.1 Termination by You

You may terminate at any time by uninstalling the App. Upon termination, this Agreement automatically ends, but Sections 3, 6, 8, 10, and any other provisions that by their nature should survive termination remain in effect.

9.2 Termination by Us

We may immediately terminate your access without prior notice if:

• You violate any provision of these Terms;
• Your use causes or is likely to cause harm to other users, third-party processors, or the App;
• We decide to discontinue operating the App (with reasonable notice).

10. Governing Law and Dispute Resolution

10.1 Governing Law

These Terms are governed by the laws of the People's Republic of China (excluding the laws of Hong Kong SAR, Macao SAR, and Taiwan).

10.2 Dispute Resolution

Any dispute arising out of these Terms or your use of the App shall first be resolved through friendly negotiation; if unresolved, the dispute shall be submitted to the people's court with jurisdiction over the developer Hedy Song's place of household registration.

10.3 Class Action Waiver (US users only)

To the extent permitted by applicable law, you agree to resolve disputes on an individual basis (not as part of a class action).

11. Changes to These Terms

We may update these Terms from time to time. Material changes will be communicated via in-App notice or by updating the effective date in this document. Your continued use after a change constitutes acceptance of the new Terms. If you do not agree, stop using and uninstall the App.

12. Miscellaneous

These Terms (together with the Privacy Policy) constitute the entire agreement between you and the developer regarding the App, superseding all prior oral or written agreements.

12.2 Severability
