+      Copyright © Verae / FlightLookup Inc. / George Lambert<br/>
+      You must accept this agreement to continue installation.
+    </div>
+
+    <div class="box">
+      <strong>Accept to install.</strong> By clicking Agree / Continue in the macOS
+      Installer, you accept these terms. If you do not agree, click Agree is not
+      available until you review, or cancel the installer.

+
+    <h2>1. License</h2>
+    <p>
+      UNLICENSED — all rights reserved unless otherwise agreed in writing with Verae.
+      Subject to this agreement, Verae grants you a limited, non-exclusive,
+      non-transferable license to install and use Verae Print Stamp on Apple
+      macOS computers you own or control, for timestamping documents with Verae.
+    </p>
+
+    <h2>2. What is sent to Verae</h2>
+    <p>
+      This software sends only a <strong>SHA-256 digest</strong> of your document
+      (and related registration metadata) to Verae for timestamp registration.
+      Document bytes remain on your computer. You are responsible for network
+      access, account credentials (including xVerae- keys), and lawful use.
+    </p>
+
+    <h2>3. Accounts and keys</h2>
+    <p>
+      Signing keys and customer tokens are tied to your Verae account. Keep keys
+      secret. Lost keys may prevent proving prior stamps. Portal:
+      https://customer.verae.ai/portal/
+    </p>
+
+    <h2>4. Restrictions</h2>
+    <ul>
+      <li>Do not reverse engineer except where mandatory law allows.</li>
+      <li>Do not remove Verae branding, copyright, or product identification.</li>
+      <li>Do not use the software to infringe others’ rights or violate law.</li>
+      <li>Do not misrepresent timestamp receipts or certificate contents.</li>
+    </ul>
+
+    <h2>5. Ownership</h2>
+    <p>
+      The software, Verae marks, and documentation remain property of Verae and
+      its licensors. No trademark license is granted beyond normal use of the
+      installed product UI.
+    </p>
+
+    <h2>6. Disclaimer</h2>
+    <p>
+      THE SOFTWARE IS PROVIDED “AS IS” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
+      IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
+      NON-INFRINGEMENT. TIMESTAMPING DEPENDS ON NETWORK, ACCOUNT, AND UPSTREAM
+      SERVICES.
+    </p>
+
+    <h2>7. Limitation of liability</h2>
+    <p>
+      TO THE MAXIMUM EXTENT PERMITTED BY LAW, VERAE AND ITS SUPPLIERS ARE NOT
+      LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE
+      DAMAGES, OR LOSS OF DATA, PROFITS, OR BUSINESS, ARISING FROM USE OF THE
+      SOFTWARE.
+    </p>
+
+    <h2>8. Termination</h2>
+    <p>
+      This license ends if you breach it. On termination, stop using and uninstall
+      the software. Provisions that by nature should survive (ownership,
+      disclaimer, liability) survive termination.
