Privacy Policy

Last updated: April 3, 2025

This Privacy Policy describes how Sylph handles information when you use our API service.

1. Information We Collect

Sylph acts as a proxy layer and does not store the content of your API requests or the responses generated by the underlying AI models. We may collect the following types of information:

• Usage Data: We may collect metadata about your API requests, such as the timestamp, the model used, request duration, and status codes. This data is used for monitoring, improving the service, and enforcing rate limits.
• API Keys: If authentication is enabled, we store a secure representation (e.g., hash) of API keys for verification purposes. The original keys are not stored.
• Error Logs: We may log error details to diagnose and fix issues with the service. These logs do not contain the content of your prompts or responses.

2. How We Use Information

We use the collected information solely for the purpose of operating, maintaining, and improving the Sylph service. This includes:

• Providing API functionality.
• Monitoring service performance and uptime.
• Troubleshooting errors and technical issues.
• Enforcing rate limits and security policies.
• Analyzing usage patterns to optimize resource allocation.

3. Information Sharing

We do not share your usage data or API key information with third parties, except as required by law or to protect the security and integrity of our service.

Your prompts and the generated responses are passed directly to the respective third-party AI providers you select via the model ID. We do not control how these providers handle your data. Please review the privacy policies of the specific AI providers you use.

4. Data Security

We implement reasonable security measures to protect the metadata we collect. However, no method of transmission over the Internet or electronic storage is 100% secure.

5. Data Retention

We retain usage metadata and error logs only for as long as necessary to fulfill the purposes outlined in this policy, or as required by law. Typically, logs are rotated and deleted periodically.

6. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
