Your Health Data is Being Shared with LinkedIn & Snapchat: A Privacy Nightmare?

Are you comfortable with your sensitive health information being shared with social media platforms like LinkedIn and Snapchat? A shocking new investigation reveals that many health-care websites are inadvertently sending user data – including responses to medical questionnaires – to these platforms. This raises serious privacy concerns and highlights a critical vulnerability in how we handle personal health information online.
The Investigation: How Did This Happen?
A joint investigation by The Markup and CalMatters uncovered this alarming practice. Researchers tested a variety of health-care websites, including those offering symptom checkers, mental health resources, and information on specific medical conditions. What they found was deeply unsettling: as users answered questions on these sites, their responses were quietly transmitted to LinkedIn and Snapchat.
What Kind of Data is Being Shared?
The data being shared isn't just trivial details. It includes potentially highly personal information, such as:
- Medical Symptoms: Descriptions of illnesses, pains, and other health concerns.
- Mental Health Information: Responses to questions about anxiety, depression, and other mental health conditions.
- Demographic Data: Age, gender, and location information, which can be used to further identify individuals.
This information, when combined with other data available on LinkedIn and Snapchat, could create a surprisingly detailed profile of a user's health status.
Why Are Websites Doing This?
The primary reason for this data sharing appears to be the use of third-party analytics tools, often embedded within websites to track user behaviour and improve the user experience. These tools, like Facebook Pixel (now Meta Pixel) and LinkedIn Insight Tag, are designed to gather data for advertising and marketing purposes. However, in many cases, the websites are not properly configured, leading to the unintended transmission of sensitive health data.
The Privacy Implications: What's the Risk?
The consequences of this data sharing are significant. Here's why this is a privacy nightmare:
- Data Breaches: Social media platforms are frequent targets of data breaches, putting sensitive health information at risk of exposure.
- Targeted Advertising: Your health data could be used to target you with personalized advertising, potentially exploiting your vulnerabilities.
- Discrimination: In the future, this data could potentially be used for discriminatory purposes, such as denying insurance coverage or employment opportunities.
- Lack of Transparency: Many users are unaware that their health data is being shared with these platforms, violating their right to informed consent.
What Can You Do?
While the onus is on websites and tech companies to fix this issue, there are steps you can take to protect your privacy:
- Be Cautious: Think twice before sharing personal health information on any website.
- Review Privacy Policies: Although lengthy and complex, try to understand how websites handle your data.
- Use Privacy-Focused Browsers and Extensions: Consider using browsers and extensions that block tracking and protect your privacy.
- Advocate for Change: Contact your elected officials and urge them to strengthen data privacy laws.
The Bottom Line:
The discovery that health-care websites are sharing sensitive information with LinkedIn and Snapchat is a stark reminder of the importance of data privacy. It’s time for websites to prioritize user privacy and for regulators to hold them accountable. Until then, proceed with caution and be mindful of the information you share online.
