- Resend — Transactional email delivery.
- Anthropic — AI-powered features (design and code generation).

6. Data Storage and Security
Your data is stored using industry-standard encryption in transit (TLS) and at rest. We implement reasonable administrative, technical, and physical safeguards to protect your information. However, no method of electronic storage or transmission is 100% secure, and we cannot guarantee absolute security.
7. Cookies
We use essential cookies for authentication and session management. These cookies are strictly necessary for the Service to function and cannot be disabled. We do not use third-party advertising or tracking cookies.
