• Full name.
• Company or organization name, where applicable.
• Email address.
• Phone and WhatsApp number.
• Type of project of interest (industrial construction, agribusiness, specialty construction, commercial construction, site development, residential, or other).

• Tax, administrative, or billing information, only when necessary to formalize a business relationship.

IDU does not request sensitive personal data through the website forms. We recommend that you do not provide information that is not necessary to handle your request.

Purposes of Data Processing

Personal data will be used for the following primary purposes, which are necessary to handle the user's request and manage the relationship with them:

• Identify and respond to requests for information, proposals, and quotes.
• Analyze the requirements of the proposed project.
• Contact the requester by phone, WhatsApp, or email.
• Provide commercial, administrative, and operational follow-up on the request.
• Compile commercial, administrative, or billing records when a business relationship is formalized.
• Address follow-up questions, clarifications, or subsequent requests.
• Comply with applicable legal, tax, contractual, and administrative obligations.
• Protect the security of the website and communications.

As a secondary purpose, IDU may use contact information to send information about its projects, services, and news. The data subject may request at any time to stop receiving these communications by writing to direccion@idu.com.mx; this will not affect the handling of their main request.

Residential Developments and Third-Party Websites

This site presents the Privada San Andrés and Laguna Residencial residential developments and links to each one's official website for models, sales information, and contact process. IDU does not collect information on this site for the sale of homes. Data entered by users on those sites is processed in accordance with the privacy notice of each development or its sales team, and IDU is not responsible for that processing.

The same applies to WhatsApp, mapping services, social networks, YouTube, and other external platforms: the processing they carry out directly is subject to their own terms and privacy policies. IDU is responsible only for the information it receives and retains through its own service channels.

Legal Basis and Consent

Personal data is processed in accordance with Mexico's Federal Law on the Protection of Personal Data Held by Private Parties (Ley Federal de Protección de Datos Personales en Posesión de los Particulares), its secondary regulations, and other applicable provisions in Mexico. By voluntarily submitting information through forms, email, WhatsApp, phone, or any other contact channel, the data subject acknowledges having read this notice and consents to the processing of their data for the purposes described.

Transfers of Personal Data

IDU may share personal data only when necessary to handle a request, comply with a legal obligation, or coordinate activities related to its operations. Where applicable, information may be disclosed to:

• Technology, web hosting, administrative, accounting, or billing providers.
• Sales teams of the residential developments, when the user's request relates to one of them or the user expressly asks for it.
• Partner companies or subcontractors involved in services requested by the user.
• Competent authorities, when there is a legal obligation or requirement.

IDU will seek to ensure that third parties involved in the processing maintain reasonable confidentiality and protection measures. Data will not be sold or marketed as databases.

Cookies and Browsing Technologies

This site may use cookies, technical logs, and similar technologies to enable its operation, maintain its security, remember preferences, understand in general terms how pages are used, and improve the browsing experience. For security reasons, IP addresses and access events are also recorded.

Depending on the site's configuration, these technologies may collect information such as browser type, device, pages viewed, browsing time, approximate IP address, and traffic source.

Users may limit or disable cookies in their browser settings. Some site features may not work properly if certain cookies are rejected.

Rights of Access, Rectification, Cancellation, and Objection (ARCO)

The data subject may request access to their personal data, correction of incorrect or outdated information, cancellation when they believe their data should no longer be processed, or object to the processing for specific purposes. They may also withdraw their consent or request limits on the use and disclosure of their data.

To exercise these rights, a request must be sent to direccion@idu.com.mx with the following information:

• Name of the data subject and a means to communicate the response.
• Clear description of the personal data related to the request.
• The right the data subject wishes to exercise.
• A document or information that reasonably verifies their identity.
• Any element that helps locate the data.

IDU will handle the request within the time limits and under the conditions established by applicable law.

Data Retention

Personal data will be kept for as long as necessary to handle the request, maintain the business relationship, comply with contractual, administrative, tax, or legal obligations, and resolve potential clarifications. Once those purposes are fulfilled, the data may be blocked or deleted, and will be retained only when a legal obligation requires it.

Security of Personal Data

IDU seeks to maintain reasonable administrative, technical, and physical measures to protect personal data against damage, loss, alteration, destruction, or unauthorized use, access, or processing. No electronic transmission or storage system can guarantee absolute security; users are also responsible for protecting their devices, accounts, and communication channels.

Data of Minors

IDU's services are directed to companies, developers, industrial firms, purchasing or operations managers, and adults with the capacity to request information or contract services. IDU does not intentionally seek to collect personal data of minors; if it detects such information without valid authorization, it may delete it.

Changes to the Privacy Notice

IDU may update this notice to reflect legal, administrative, technological, commercial, or site-operation changes. Changes will be available on this same page with the date of the last update.
