Cookie Policy

1. Introduction

At Nexus Stem Cells (“we”, “us”, or “our”), we use cookies and similar tracking technologies on our website (the “Platform”). This Cookie Policy explains what cookies are, why we use them, how you can control them, and how we comply with applicable laws, including Mexico’s Ley Federal de Protección de Datos Personales en Posesión de los Particulares (LFPDPPP, 2025) and, where applicable, the General Data Protection Regulation (GDPR) for users in the European Economic Area. For more information about how we process your personal data, please see our Privacy Policy.

2. What Are Cookies?

Cookies are small text files that are placed on your computer, smartphone, or other device when you visit a website. They are widely used to make websites work more efficiently, enhance user experience, and provide information to the website owners. Cookies may be set by us (“first‑party cookies”) or by third‑party services we use (“third‑party cookies”).

3. What Types of Cookies Do We Use?

We categorise cookies as follows:

• Essential Cookies (Strictly Necessary): These cookies are required for the basic operation of our Platform. They enable core functionality such as page navigation, security, and access to secure areas. You cannot opt out of these cookies because the website cannot function properly without them. These cookies do not require your consent under the LFPDPPP.
• Preference Cookies (Functional): These cookies allow our Platform to remember choices you make (such as your language preference or region) and provide enhanced, more personalised features. These cookies require your explicit consent.
• Analytics Cookies (Performance): These cookies collect information about how you use our Platform (e.g., which pages you visit most often, if you receive error messages). All information collected is aggregated and anonymised. We use this data to improve our Platform. These cookies require your explicit consent.
• Marketing Cookies: These cookies are used to deliver advertisements that are more relevant to you and your interests. They may be placed by our advertising partners. These cookies require your explicit consent.

The following table lists the specific cookies we may use, their purposes, and their retention periods:

We currently use Google Analytics 4 (GA4) with anonymise_ip enabled to protect your IP address. GA4 does not store IP addresses, and we do not combine this data with other personally identifiable information. For more information, please see How Google uses information from sites that use Google Analytics. We may add or remove third‑party analytics services from time to time; any changes will be reflected in this Cookie Policy.

4. How We Obtain Your Consent

When you first visit our Platform, a cookie banner will appear. The banner:

• Informs you that we use cookies.
• Provides a link to this Cookie Policy.
• Offers you the ability to accept or reject all non‑essential cookies (preferences, analytics, marketing).
• Allows you to manage your preferences granularly through our Cookie Preference Manager.

Under the LFPDPPP (2025), we are required to obtain your explicit, prior, opt‑in consent before placing any non‑essential cookies on your device[reference:2]. This means we will only set these cookies after you actively click “Accept” or select your preferences. Pre‑ticked checkboxes, cookie walls, and continued browsing do not constitute valid consent. Additionally, cookie consent is valid for a maximum of 12 months, after which we will request your consent again[reference:3].

We maintain records of your consent (including timestamp, cookie preferences, and policy version) for a minimum of 12 months, as required by law[reference:4].

5. How to Manage or Withdraw Consent

You can manage your cookie preferences at any time by clicking the “Cookie Preferences” link in the footer of every page. This will reopen the Cookie Preference Manager, where you can adjust your settings.

Additionally, you can set or modify your browser controls to accept or refuse cookies. Most web browsers allow you to:

• View and delete cookies already stored on your device.
• Block cookies from specific websites or all websites.
• Set preferences for first‑party and third‑party cookies.

Instructions for managing cookies in popular browsers are available at the following links:

• Google Chrome
• Mozilla Firefox
• Safari
• Microsoft Edge

If you choose to reject or disable cookies, some parts of our Platform may not function properly or may be slower.

6. Consent for Users in the European Economic Area (GDPR)

If you are located in the European Economic Area, the GDPR applies to our use of cookies. Under the GDPR, we must obtain your freely given, specific, informed, and unambiguous consent before setting any non‑essential cookies[reference:5]. Our cookie banner and preference manager are designed to meet these requirements. You have the right to withdraw your consent at any time with the same ease as you gave it. Withdrawal does not affect the lawfulness of processing based on consent before its withdrawal.

7. Updates to This Cookie Policy

We may update this Cookie Policy from time to time to reflect changes in our practices, legal requirements, or regulatory guidance. The “Last updated” date at the top of this page indicates when the most recent changes were made. If we make material changes, we will notify you by posting a prominent notice on our website or, where required, by requesting fresh consent. Your continued use of the Platform after any such changes constitutes your acceptance of the revised Cookie Policy.
