Introduction
KizunaX ("we", "our", "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our AI API platform and related services.
Information We Collect
We collect information you provide directly: account details (name, email, password), billing information, API usage data, and support communications. We also automatically collect device information, IP addresses, browser type, and usage analytics through cookies and similar technologies.
How We Use Your Information
We use your information to provide and maintain our services, process transactions, send service notifications, monitor usage patterns for platform improvements, enforce our terms of service, and comply with legal obligations.
Information Sharing
We do not sell your personal information. We may share data with trusted service providers (payment processors, cloud hosting, analytics), when required by law, or to protect our rights. All third-party providers are bound by confidentiality agreements.
Data Security
We implement industry-standard security measures including encryption at rest and in transit (TLS 1.3), secure API key storage with AES-256 encryption, regular security audits, and access controls. However, no method of transmission over the Internet is 100% secure.
Cookies & Tracking
We use essential cookies for authentication and session management, and optional analytics cookies to understand how our platform is used. You can manage cookie preferences through your browser settings.
Data Retention
We retain your account data for as long as your account is active. API usage logs are retained for 90 days, billing records for 7 years (as required by law). You may request deletion of your account and associated data at any time.
Your Rights
Depending on your jurisdiction, you may have the right to access, correct, or delete your personal data, object to processing, request data portability, and withdraw consent. To exercise these rights, contact our privacy team at privacy@kizunax.io.
Children's Privacy
Our services are not directed to individuals under 16. We do not knowingly collect personal information from children. If we learn we have collected such information, we will promptly delete it.
