3.1 What We DO NOT Do

3.2 Third-Party AI Services

When you use our service, your prompts are sent to the AI model providers you select (OpenAI, Anthropic, Google, xAI, etc.) using your API keys. Each provider has their own privacy policy and data handling practices. We recommend reviewing their policies.

3.3 Service Providers

We may share your information with trusted third-party service providers who assist us in operating our service, such as:

• Payment processors (for billing and subscription management)
• Cloud hosting providers (for data storage and computing)

• Email service providers (for transactional emails)

These providers are contractually obligated to protect your data and use it only for the purposes we specify.

3.4 Anonymized Data for Marketing

We may anonymize and aggregate your prompts and usage data to create general insights, trends, and marketing materials. For example:

• "Users found that Model X performed 20% better on coding tasks"
• "Common use cases include content writing and data analysis"
• Example prompts demonstrating service capabilities (with all identifying information removed)

This anonymized data cannot be traced back to you or your account.

We may disclose your information if required by law, court order, or government regulation, or if we believe disclosure is necessary to protect our rights, your safety, or the safety of others.

However, no method of transmission or storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.
