At our company, privacy begins with trust.

In 2001, Merck & Co., Inc. (Kenilworth, NJ, USA), which operates as MSD outside of the U.S. and Canada, established a Privacy Office to develop and oversee a global privacy program for our operations around the world. Our program is based on four privacy values that provide the foundation for responsible engagement, interactions and use of information about people:

  • respect for individual privacy expectations,
  • building and preserving trust,
  • preventing privacy harms, and
  • compliance with the letter and spirit of privacy and data protection laws around the world.

Our privacy program is built on a platform of organizational accountability for privacy, stewardship of the data we use to operate our business, consistent global privacy practices and standards that carry on our tradition of upholding high ethical standards across our business practices, and ongoing oversight to ensure that we continue to respond to changes in privacy expectations as technology and our business continue to evolve. For more information about our program, please see the global privacy program section of our corporate responsibility report.

Our Approach to Privacy Trust

Since we believe that trust is a core privacy value and essential to our corporate mission to discover, develop and provide innovative products and services that save and improve lives around the world, our global privacy program strategy is centered on two primary goals that aim to drive trust in how we engage with people and how we access, use and transfer information about people around the world:

Consistent Global Standards

Since we established our global privacy program in 2001, we have worked to implement and uphold consistent global privacy standards to provide assurance for how we manage our privacy and data protection obligations across countries and regions and to support our certifications under the following privacy frameworks recognized by regulators:

  • US-EU Safe Harbor (2001)
  • US-Swiss Safe Harbor (2009)
  • APEC Cross Border Privacy Rules (2013)
  • EU Binding Corporate Rules (2016)
  • US-EU Privacy Shield (2016)
  • US-Swiss Privacy Shield (2018)

Each of our certifications is based on our Cross Border Privacy Rules Policy


We recognize that it can be difficult and overwhelming for people to understand all of the different ways that information about them can be observed, sensed, collected, shared, used, analyzed and transferred, so we use a variety of approaches to support our goal of making our practices transparent both to people about whom we process information as well as the regulators and their agents who review our practices. Key examples include:

  • Online Privacy – our Internet Privacy Policy describes the ways in which we process information about people online;
  • Cookies – our Cookie Privacy Commitment supports our Internet and describes the ways in which our web sites and online services use cookies and other online trackers;
  • Comprehensive Privacy Notices – these are intended to provide a thorough perspective on how our privacy practices apply to specific stakeholders.;
  • Mobile App Privacy as a supplement to our Internet Privacy Policy we provide certain mobile app privacy disclosures below;
    • Protection of Social Security Numbers and other government-issued identification numbers; and
    • Contextual Notices – which we provide at the time you use or participate in our services.
