      <h2>4. Why we process your data</h2>
      <ul>
        <li>
          <strong>Contract performance:</strong> to provide video encoding, metadata handling,
          playlist actions, API access, and YouTube upload features you request
        </li>
        <li>
          <strong>Legitimate interests:</strong> to secure our service, prevent abuse, improve
          reliability, and enforce our terms
        </li>
        <li>
          <strong>Legal obligations:</strong> where required by tax, accounting, or regulatory law
        </li>

      </ul>

      <h2>5. Third-party services</h2>
      <p>We use trusted third parties to operate Songs2VID, including:</p>
      <ul>
        <li>
          <strong>Google / YouTube:</strong> authentication and video uploads via Google OAuth and
          the YouTube Data API. Your use of Google and YouTube is also subject to{" "}

          <strong>Hosting and infrastructure providers:</strong> servers, databases, queues, and
          storage
        </li>
        <li>
          <strong>Stripe:</strong> Pro subscriptions, Free-plan credit top-ups, and related billing

          )
        </li>
        <li>
          <strong>Matomo (self-hosted analytics):</strong> privacy-friendly analytics we operate at
          analytics.atakanozban.com to measure visits and improve Songs2VID. Analytics data stays on
          infrastructure we control; we do not sell it to advertising networks.
        </li>
      </ul>
      <p>
        These providers process data only as necessary to deliver their services and under
        appropriate contractual safeguards where required.
      </p>

      <h2>6. Google / YouTube user data (Limited Use)</h2>
      <p>
        Songs2VID&apos;s use and transfer to any other app of information received from Google APIs
        will adhere to the{" "}
        <a
          href="https://developers.google.com/terms/api-services-user-data-policy"
          target="_blank"
          rel="noopener noreferrer"
        >
          Google API Services User Data Policy
        </a>
        , including the Limited Use requirements.
      </p>
      <p>
        We request Google OAuth access (including the YouTube Data API scope needed to upload videos
        and manage playlists on your connected channel) solely to provide prominent, user-facing
        features of Songs2VID: signing you in, connecting your channel, encoding your media, uploading
        videos you create, and creating or listing playlists you request. We do not use Google user
        data for advertising, credit scoring, or unrelated profiling.
      </p>
      <p>
        We do not sell, share, transfer, or disclose Google user data obtained via Google OAuth /
        YouTube APIs to third parties, except as needed to operate the Service infrastructure under
        our control or when required by law. Google / YouTube themselves process data when we call
        their APIs on your behalf to perform actions you initiate.
      </p>
      <p>
        You can revoke Songs2VID&apos;s access to your Google account at any time in{" "}
        <a
          href="https://security.google.com/settings/security/permissions"
          target="_blank"
          rel="noopener noreferrer"
        >
          Google Account → Security → Third-party access
        </a>
        . After revocation (or when tokens can no longer be refreshed), we will stop using those
        credentials and delete or invalidate stored YouTube OAuth tokens and related connection data
        associated with that consent, subject to short-term backup or security logs and any legal
        retention duties.
      </p>

      <h2>7. Data retention and account deletion</h2>
      <ul>
        <li>
          Uploaded source files and generated outputs are retained only as long as needed to complete
          your jobs (typically removed after successful processing/upload or when no longer required)
        </li>
        <li>Account data is kept while your account remains active</li>
        <li>Billing records may be retained as required by law</li>
        <li>Logs are retained for a limited period for security and troubleshooting</li>
        <li>
          API key hashes are removed when you revoke the key, downgrade from Pro (where applicable),
          or delete your account
        </li>
      </ul>
      <p>
        You may delete your account from <strong>Dashboard → Settings</strong> (account deletion
        control) or by emailing{" "}
        <a href={`mailto:${LEGAL_OPERATOR.email}`}>{LEGAL_OPERATOR.email}</a>. Deletion removes
        account and connection data from active systems subject to legal retention obligations
        (for example certain billing records). Cancelling a subscription does not by itself delete
        your account.
      </p>

      <h2>8. Self-hosted deployments</h2>
      <p>
        If you deploy Songs2VID on your own infrastructure, you are the data controller for data
        processed on your instance. This Privacy Policy applies to the hosted cloud service
        operated by us, not to independent self-hosted installations unless we provide managed
        hosting for you under contract.
      </p>

      <h2>9. Your rights</h2>
      <p>Depending on your location, you may have the right to:</p>
      <ul>
        <li>Access the personal data we hold about you</li>
        <li>Request correction or deletion</li>
        <li>Restrict or object to certain processing</li>
        <li>Data portability</li>
        <li>Withdraw consent where processing is consent-based</li>
        <li>
          Lodge a complaint with a supervisory authority (in Hungary, the Nemzeti Adatvédelmi és
          Információszabadság Hatóság — NAIH)
        </li>
      </ul>
      <p>
        To exercise these rights, contact{" "}
        <a href={`mailto:${LEGAL_OPERATOR.email}`}>{LEGAL_OPERATOR.email}</a>, or use in-product
        account deletion where available. You may also revoke Google access as described in section
        6.
      </p>

      <h2>10. Cookies, analytics, and local storage</h2>
      <p>
        We use essential cookies and similar technologies for authentication, session management,
        and security.
      </p>
      <p>
        We also use <strong>Matomo</strong>, a self-hosted analytics tool on{" "}
        <code>analytics.atakanozban.com</code>, on our website (including the landing page and
        dashboard) and documentation site. Matomo helps us understand how people use Songs2VID so we
        can improve functionality, reliability, and content. Typical data includes pages viewed,
        approximate location derived from IP, device/browser type, referring site, and interaction
        events. We configure Matomo for our domains under <code>*.songs2vid.com</code>.
      </p>
      <p>
        We collect this analytics data to improve the Service, not to sell personal profiles to
        advertisers. The legal basis is our legitimate interest in operating and improving
        Songs2VID (and consent where required by local law). You can block analytics with browser
        settings, extensions, or Do Not Track / equivalent controls where supported. For rights
        requests related to analytics data, contact{" "}
        <a href={`mailto:${LEGAL_OPERATOR.email}`}>{LEGAL_OPERATOR.email}</a>.
      </p>

      <h2>11. Security</h2>
      <p>
        We implement appropriate technical and organizational measures to protect your data,
        including encryption in transit, encrypted storage of YouTube OAuth tokens at rest, access
        controls, and isolated processing environments. No method of transmission or storage is
        100% secure.
      </p>

      <h2>12. International transfers</h2>
      <p>
        If data is transferred outside your country, we ensure appropriate safeguards such as
        standard contractual clauses or equivalent mechanisms where required by law. Google, Stripe,
        and infrastructure providers may process data in other countries as described in their
        policies.
      </p>

      <h2>13. Children</h2>
      <p>
        Songs2VID is not directed at children under 16. We do not knowingly collect personal data
        from children. If you believe a child has provided us data, please contact us.
      </p>

      <h2>14. Changes to this policy</h2>
      <p>
        We may update this Privacy Policy from time to time. Material changes will be posted on
        this page with an updated effective date. If we change how we use Google user data, we will
        update this policy and, where required, notify you or obtain renewed consent.
      </p>
