Initiative
Security and ethical use of our ecosystem
About the initiative
Our users’ rights come first
The success of our business depends on the trust of our users and sellers. That’s why ensuring the security and privacy of personal and financial information, the integrity and availability of our technological infrastructure, and the ethical use of our platform are essential conditions for everything we do.
How it works
Cybersecurity
We are a tech company. Therefore, implementing data protection and fraud prevention on our systems require effort and dedication by our IT professionals. We have round-the-clock monitoring in place to avoid information leakage, and prevent and detect any potential cyber attack. The entire infrastructure supporting Mercado Libre's ecosystem is monitored, including all critical processes, equipment, and suppliers that are directly involved. You can find detailed information on the measures and procedures adopted in the Annual Report.
Privacy center
We exceed the legal requirements in each country, tailoring our regional operations to the strictest local regulations, such as Brazil’s General Data Protection Law (LGPD).
Anyone using our platforms agrees to how their information is handled according to our Privacy Statement, which is available on the homepage of each local site. Plus, our Privacy Center gives users full control over their personal data processing.
Ethical use of our platform
Each Mercado Libre site has specific procedures to prevent illegal activities on our platform, in accordance with the Terms and Conditions and Publication Policy of each country. To protect the health and safety of those who use our solutions, we prohibit over 40 categories of products and services, such as firearms and narcotics. In addition, we ensure that all products offered in Mercado Libre stores comply with applicable requirements and regulations regarding information and labeling.
We rely on technologies and artificial intelligence to help us analyze, pause, or remove listings that violate our Terms and Conditions. Also, our listings have a Report button so anyone can report products that break the applicable rules. Depending on the type of violation committed or its recurrence, the penalty can range from platform expulsion and/or reporting to authorities.
Responsible use of AI
We understand that generative AI tools have significant potential in our ecosystem to keep creating value for our users. For this reason, we created MELI's AI Principles and AI Governance Policy to ensure these tools are used responsibly and safely, following the highest ethical and legal standards.
Brand Protection Program
To help protect intellectual and industrial property and tackle any violations users might make on our platform, we offer the Brand Protection Program (BPP), a dedicated channel for reporting listings that violate trademarks, copyrights, related rights, patents, industrial models and designs, and more.
Fight against counterfeiting and piracy
The Mercado Libre Anti-Counterfeiting Alliance (MACA) is a regional initiative that, since 2021, has promoted collaboration with rights holders and brand associations to combat the sale of counterfeit and pirated products on our marketplace. We currently work with more than 40 Top of Mind brands and associations.
In 2025, we increased the efficiency of proactive removals of counterfeit and pirated products, achieving results up to 22 times higher than infringement reports submitted by members of the initiative through the BPP. In addition, in coordination with our partners, we have pursued criminal actions against organizations that use the platform for illicit activities.
Transparency
We were the first Latin American company to periodically publish a Transparency Report, which compiles projects and results in the areas of digital security, data protection, privacy, and anti-piracy efforts.
Anti-Money Laundering and Terrorist Financing
At Mercado Libre and Mercado Pago we have developed controls, collaboration agreements, and continuous improvement processes to prevent our products and services from being used for any type of illegal activity or contrary to our terms and conditions of use.
We are clear that trust is the foundation of our business, and transparency is the best way to honor our commitment to our users.
