        <h2>Data Controller</h2>
        <p>
            VISIALIS, SAS with share capital of €200,000, registered with the Paris Trade Register under number 478 885 122,<br>
            59 rue de Ponthieu, 75008 Paris, France.
        </p>

        <h2>General Principles</h2>
        <ul>
            <li>Alter does not collect, store or transmit any personally identifiable data.</li>
            <li>The application relies exclusively on public data available through EVM-compatible RPC endpoints.</li>
            <li>No account, identifier or subscription is required. When a user connects a wallet and signs to prove ownership of an EVM address, the cryptographic proof is stored locally on the device and never sent to VISIALIS or any third party.</li>
        </ul>
        <p>For contractual obligations, please review the <a href="terms_en.html">Terms of Use</a>.</p>

        <h2>Network Connections</h2>
        <p>
            Outbound traffic is limited to public RPC endpoints configured by default or added by the user. VISIALIS does not operate proprietary servers to intercept or enrich these requests. Should VISIALIS offer its own RPC endpoint in the future, this will be clearly indicated in the application and documentation.
        </p>
        <p>
            The web version of Alter is delivered as a static application: all interactions remain within the user’s browser. No data related to the addresses viewed or wallet signatures is sent back to the hosting server.
        </p>

        <h2>Cookies and Local Storage</h2>
        <p>
            The web version may store technical preferences locally (such as the status of an information banner). These data stay on the user’s device and are never transmitted to VISIALIS.
        </p>

        <h2>Security</h2>
        <p>
            VISIALIS recommends using trusted RPC endpoints only. If there is any doubt about a third-party endpoint, users should remove it from the configuration.
        </p>

        <h2>User Rights</h2>
        <p>
            As no personal data is collected, there is no data enabling rights of access, rectification or erasure. For any question, please contact: <a href="mailto:contact@visialis.fr">contact@visialis.fr</a>.
        </p>

        <h2>Changes</h2>
        <p>
            This policy may be updated to reflect service or legal developments.
