Frequently Asked Questions

The Apple Women’s Health Study is the first long-term research study of this scale and scope that aims to advance the understanding of menstrual cycles and their relationship to various health conditions including infertility, menopause, and health across the lifespan using data collected with a mobile application.

Certain behaviors and habits could have an impact on menstrual cycles and gynecologic health conditions including infertility, menopause, and polycystic ovary syndrome (PCOS). This study aims to advance the understanding of the relationship between menstrual cycles, health, behavior, and habits. This will also help inform development of new products for menstrual cycles, as well as early screening and risk assessment of gynecologic conditions.

You can participate in this study with your iPhone and the Apple Research app. The study will ask you to:

1. Provide your consent to collect data from your iPhone and Apple Watch (optional), such as your Health app data, medical history data, sensor data, and other device/Apple Research app related data.
2. Complete occasional, short surveys to help researchers understand the relationship between your menstrual cycle, health, behaviors, and habits.
3. If you are menstruating, track your menstrual cycle in the Health app with Cycle Tracking or any other menstrual cycle tracking app that writes your data to the Health app.

Any information collected or accessed by the Research app is stored with encryption if you have a passcode on your iPhone. Information from the Research app will be shared with the study only after you have joined the study by signing the informed consent form, and have authorized the study to collect or access information in the Research app. Your information will be encrypted when transferred to and stored on Apple’s servers that are designed to meet the technical safeguard requirements of the Health Insurance Portability and Accountability Act (HIPAA).

The Apple Women’s Health Study has recently been granted a Certificate of Confidentiality by the National Institutes of Health providing additional privacy protections for the Study. This means researchers cannot release information that may identify you in any regulatory or legal action unless you say it is okay. This protection covers federal, state, civil, criminal, administrative, legislative, and other proceedings, such as court subpoenas or lawsuits.

The Certificate of Confidentiality does not stop you from willingly releasing information about your involvement in this research. It also does not prevent you from accessing or sharing your own information. Researchers may also still release information about you when you say it is okay. For example, you may give them permission to release information to insurers, medical providers, or any other persons not connected with the research.

Your identifiable data can only be released by Study researchers in a few additional circumstances. For example, researchers are still required to comply with federal, state, or local laws that require reporting in certain instances. These include laws that require reporting of child or elder abuse, some infectious diseases, and threats to harm yourself or others. Researchers may also still disclose information about the Study and participants to organizations who are responsible for oversight of safe research practices such as the Study’s Institutional Review Boards (IRB), the Food and Drug Administration (FDA), and agencies with the United States federal or state governments.

Only certain authorized people and institutions will have access to the study data. These include Apple (the sponsor), the Harvard T.H. Chan School of Public Health, the National Institute of Environmental Health Sciences (one of the National Institutes of Health), and the Research Studies Support Center (operated by Apple’s third-party service provider). Advarra Institutional Review Board and certain regulatory or government agencies (such as the Department of Health and Human Services) may also have access to the study data under certain circumstances.

Study data that directly identifies you (such as your name, email address, and phone number) will be kept separate from the rest of your study data and replaced with a random code that is unique to you, but which is not based on any information about you.  Most authorized people and institutions will only have access to Research app data with directly identifying information removed. However, identifiable information will be made available to a limited number of study staff at the Harvard T.H. Chan School of Public Health who need this to administer the study, or to the Research Studies Support Center if you reach out for support.  When required by law, legal process or litigation, study data in identifiable form may also be made available to the Advarra Institutional Review Board and certain regulatory or government authorities.

Please refer to “Who will have access to my study data?” in the informed consent form for more information about who has access to the study data and what types of study data they may access.

Apple will not be able to access any information that directly identifies you (such as your name, email address, and phone number) that is collected through the Research app.

However, if you call the Research Studies Support Center regarding a technical issue with the Research app, the Research Studies Support Center may ask you if you want to be transferred to AppleCare for additional support. With your consent, you may be transferred to help address your technical question(s), in which case Apple may have access to certain information that directly identifies you and may know that you are participating in a study.

The Apple Research app can be used to find available Apple research studies, understand the goals of the study, see the data it will collect, and enroll and participate in the studies by providing consent.
