7. AI-Generated Content

The Service uses third-party AI models to generate text, images, videos, and other content. AI-generated content may contain inaccuracies or errors. You are solely responsible for reviewing and verifying AI-generated content before use. The Company does not guarantee the accuracy, completeness, or suitability of AI-generated content for any purpose.

8. Data Handling

We respect your privacy and handle data according to the following policies:

• Your account password is not stored on our servers.
• Your data is never used to train AI models.
• For purposes such as translation and fraud detection, data may be transmitted to the APIs of Anthropic, Google, and OpenAI. Each of these providers explicitly states that data received through their APIs is not used to train their AI models, and we only use AI models whose policies on this point we have verified. While data may be temporarily retained on these platforms, it is automatically deleted after a certain period.
• Content you input into the Service is not stored in any database or other persistent storage managed by the Company. On the server side, we only record usage metrics (such as token and character counts) and the minimum information required to prevent abuse (such as the IP address for anonymous use).
• Screen captures and inputs or outputs processed through AI features are sent to third-party AI providers for processing. They are not retained on our servers beyond the duration necessary for processing, and are completely deleted the moment you reset a session.
• By design, we do not store usage data other than meeting minutes, and our employees do not view the content you input or any translation results.
• Meeting recordings processed by the AI Notetaker feature are handled in accordance with our Privacy Policy. They are recorded in our environment only when you choose the cloud storage setting, and even in that case our employees do not view the recordings or the resulting minutes. When you choose the local storage setting, nothing is recorded in our environment and the data is stored only on your device.

The Company implements the following security measures to protect your data:

• All communications between you and the Service, and between the Service and external providers, are encrypted using HTTPS (TLS 1.2 or higher).
• User data stored by the Company is encrypted at rest when saved in databases, backups, and other persistent storage.
• We apply a Web Application Firewall (WAF) to our primary public endpoints to block common attacks and unauthorized access attempts.

10. Intellectual Property Rights

• Intellectual property rights in text, images, videos, and other data you submit through the Service, as well as information output by the Service based on such data (collectively, "Transmitted/Received Information"), shall belong to you.
