    1. Introduction

    Kernio AI ("we", "our", or "us") operates the website kernioai.com and the Kernio AI platform. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our service.

    • Device information: Browser type, operating system, and device identifiers.

    3. How We Use Your Information

    • Detect and prevent fraud, abuse, and security threats.
    • Comply with legal obligations.

    4. AI Processing

    When you use our AI features, your content is sent to third-party AI providers (such as OpenAI and Anthropic) for processing. We send only the minimum context necessary for each operation. These providers process your data according to their own privacy policies and data processing agreements. We do not use your content to train AI models.

    5. Data Sharing

    We do not sell your personal information. We share data only with:

    • Service providers: Supabase (hosting & database), Lemon Squeezy (payments), Resend (transactional emails), OpenAI/Anthropic (AI processing).
    • Legal requirements: When required by law, regulation, or legal process.

    6. Data Storage & Security

    Your data is stored on Supabase infrastructure. We use industry-standard security measures including encryption in transit (TLS), row-level security policies, and secure authentication. Payment data is handled entirely by Lemon Squeezy and is never stored on our servers.

    7. Data Retention

    We retain your account data and content for as long as your account is active. If you delete your account, we will delete your personal data within 30 days, except where retention is required by law (e.g., billing records). Top-up credits expire 6 months after purchase.

    8. Your Rights

    Depending on your jurisdiction, you may have the right to:

    • Access the personal data we hold about you.
    • Request correction or deletion of your data.
    • Export your content.
    • Withdraw consent for optional data processing.
    • Lodge a complaint with a data protection authority.

    9. Cookies

    We use essential cookies for authentication and session management. We use a regional pricing cookie to remember your detected pricing tier. We do not use third-party advertising or tracking cookies.

    10. Children's Privacy

    Our service is not directed to children under 16. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us.

    11. Changes to This Policy

    We may update this Privacy Policy from time to time. We will notify you of material changes by email or by posting a notice on our website. Your continued use of the service after changes constitutes acceptance.
