            <p>
              The Other Dude is self-hosted software. All data is stored on infrastructure
              you own and control. The authors do not collect, transmit, or have access to any
              of your data. This privacy policy describes what data the Software stores locally
              on your deployment.

            <h2 className="text-lg font-semibold text-text-primary">2. Data We Store</h2>
            <p>When deployed, The Other Dude stores the following data in your local database:</p>
            <ul className="list-disc pl-6 space-y-1">
              <li>
                <strong>User accounts:</strong> Email addresses, names, and authentication data.
                Passwords are never stored &mdash; The Other Dude uses SRP-6a zero-knowledge
                authentication, meaning the server only stores a cryptographic verifier derived
                from your password, never the password itself.
              </li>
              <li>
                <strong>Encryption key material:</strong> Per-user encrypted key sets for
                zero-knowledge encryption. Your Secret Key is stored only in your browser
                (IndexedDB) and is never transmitted to or stored on the server.
              </li>
              <li>
                <strong>Device credentials:</strong> RouterOS usernames and passwords for managed
                devices, encrypted at rest with AES-256-GCM via per-tenant envelope encryption.
              </li>
              <li>
                <strong>Device data:</strong> Hostnames, IP addresses, firmware versions, hardware
                models, and configuration backups retrieved from your MikroTik devices.
              </li>
              <li>
                <strong>Metrics:</strong> Time-series performance data (CPU, memory, bandwidth,
                wireless stats) collected from your devices by the polling service.
              </li>
              <li>
                <strong>Audit logs:</strong> Records of user actions within the portal (logins,
                configuration changes, device management operations). Encrypted at rest with
                zero-knowledge encryption.
              </li>
              <li>
                <strong>Certificates:</strong> TLS certificates and encrypted private keys generated
                by the internal certificate authority for device API connections.
              </li>
            </ul>

            <h2 className="text-lg font-semibold text-text-primary">3. No External Transmission</h2>
            <p>
              The Other Dude does not send any data to external servers, analytics services,
              or third parties. All communication occurs between the portal and your MikroTik
              devices over your local or private network. The only outbound connections are:
            </p>
            <ul className="list-disc pl-6 space-y-1">
              <li>
                <strong>Firmware checks:</strong> Queries the MikroTik download server to check
                for RouterOS updates (no device data is sent).
              </li>
              <li>
                <strong>Email notifications:</strong> If configured, alert emails are sent via
                your SMTP server. Only alert data you configure is included.
              </li>
              <li>
                <strong>Webhook notifications:</strong> If configured, alert data is sent to
                webhook URLs you specify.

            <h2 className="text-lg font-semibold text-text-primary">4. Multi-Tenancy</h2>
            <p>
              The Other Dude supports multiple tenants (organizations). Data isolation between
              tenants is enforced at the database level using PostgreSQL Row-Level Security (RLS).
              Each tenant can only access their own devices, users, and data. The super_admin
              role has cross-tenant visibility for platform administration.
