The data economy and its impact on health and fitness fields

In the modern digital environment, data is often regarded as one of the most valuable raw materials. Companies across various sectors – advertising, consumer goods, finance – use user data to improve services, predict trends, and optimize processes. Regarding health and fitness technologies, personal information such as workout habits, nutrition logs, biometric indicators, and even geolocation reveals important insights about user behavior, priorities, or health status.

Although these insights can drive significant innovation – such as recommending targeted workouts or detecting early signs of metabolic disorders – data commercialization can also violate privacy if not properly regulated. Companies may share or sell data to third parties, create ads based on user vulnerabilities, or retain data longer than necessary. This has sparked discussions: how to leverage the positive potential of data without engaging in exploitative or risky practices?

2. What information do modern technologies collect?

2.1 Fitness wearables and apps

  • Activity indicators: steps, distance covered, stairs climbed, heart rate, sleep duration/quality, sometimes advanced measurements like VO2 max or HRV.
  • Location data: GPS route while running or cycling, patterns of geographic activities.
  • Personal data: age, gender, weight, height, health condition information – often used to calculate calories or workout intensity.

2.2 Telemedicine and health portals

  • Medical records: diagnoses, test results, prescription history.
  • Insurance and payment information: financial data, personal contact details, policy numbers.
  • Remote consultation content: video call recordings, text chats with doctors.

2.3 Additional data: social media interaction

Many users share progress, "before and after" photos, or nutrition details on social networks. Although voluntary, platforms or data intermediaries can collect this information and correlate it with other sources, creating a very detailed user profile, sometimes without the user's clear awareness.

3. Privacy risks: threats to personal information

3.1 Data breaches and unauthorized access

There is no 100% reliable security. Even large health or fitness companies have experienced data breaches exposing user logins, demographic details, or health records. Hackers can exploit vulnerabilities in cloud services, IoT devices, or insufficient data encryption. Consequences can be devastating – identity theft, insurance fraud, or disclosure of highly confidential conditions.

3.2 Data sharing with third parties

Some companies share or sell aggregated user data to advertising agencies, insurers, or scientific research. Although anonymization is promised, reidentification is possible by combining multiple sources. For example, a user's step frequency or location data can be matched with public records, allowing identification of daily habits or even health issues.

3.3 Manipulative targeting

Advertising or insurance decisions may be tailored to "risky" user groups, for example, offering more expensive services to those with certain health indicators. This exploits user sensitivity: intensive promotion of certain products or invasive ads can undermine people's trust and autonomy.

3.4 Government or employer surveillance

In some work or legal environments, data collected from wellness programs may be used to assess employees' lifestyles. Without clear privacy policies, there is fear that non-compliance could lead to unfavorable insurance rates or workplace discrimination.

4. Security measures: data protection on devices and platforms

4.1 Encryption and secure data transmission

  • End-to-End encryption: information is encrypted from sender to receiver, leaving no possibility to intercept it during transit.
  • SSL/TLS: ensures that data between the app and server travels not as text but as an encrypted stream ("https://" indicator). This is necessary so that no one can easily intercept the communication.

4.2 Access management and authentication

  • Two-factor authentication (2FA): an additional code or biometrics is required if the password is leaked.
  • Role-based rights: In clinical settings, employees see only what is necessary for their duties, reducing accidental data viewing or leakage.

4.3 Secure media

  • Reliable cloud services: big names (AWS, Azure, GCP) often have high security standards, properly protecting servers. Small companies may lack such resources.
  • Regular checks and testing: routine security audits or “penetration tests” help identify vulnerabilities before criminals do.

All these security fundamentals dramatically reduce the likelihood of leaks, but users themselves should also remain vigilant (use strong passwords, updates).

5. Ethical data use: consent, transparency, and fair practice

Beyond technical solutions, the question is asked how exactly data will be used, shared, or sold to others. Ethical principles include ensuring informed consent, open communication about data handling, and the requirement that data be used for welfare, not manipulation.

5.1 Informed consent and clarity

  • Understandable policies: terms of use should be written in plain language, not confusing legal jargon.
  • Detailed consent: people can agree to allow some uses of their data (e.g., anonymous research) but reject others (e.g., targeted advertising). Such a flexible consent management system clarifies collaboration.

5.2 Transparency about the data lifecycle

Companies increase trust if they specify:

  • How long data is stored and how (or if) it is deleted when no longer used.
  • Whether data is shared with third parties, and in what form (anonymous or identifiable).
  • How user content (photos, workout logs) remains private or can be used for advertising.

5.3 Ensuring benefits of data to the user

  • Product improvement: aggregated feedback can help calibrate sensors more accurately, develop new app features useful to the user.
  • Scientific research: with consent, large volumes of anonymized data allow discovering links between activity, morbidity, lifestyle, and diseases, ultimately contributing to public well-being.

By adhering to ethical standards, data use can help fight diseases, prevent fraud, or promote innovation, while also preserving personal autonomy and dignity.

6. Regulations and standards governing data privacy

Various legal frameworks regulate health data protection and broader user privacy assurance. Among the most important are:

  • HIPAA (JAV): The Health Insurance Portability and Accountability Act, which sets rules on how medical (PHI) information is handled. However, many fitness apps or companies not directly connected to healthcare providers may not fall under HIPAA unless they collaborate with a healthcare institution.
  • GDPR (EU): The General Data Protection Regulation requires compliance with strict data processing, consent, and user rights standards. Apps or platforms serving EU residents must comply with GDPR.
  • CCPA (California): gives residents more control over personal data – the right to opt out of sales, request deletion, etc.
  • Other new/upcoming laws: many countries are considering or already applying stricter personal privacy standards directly affecting fitness and health data.

However, these rules often face uneven enforcement, leaving gaps. Activists and lawyers call for unified, deeper protection, especially in the context of wearable devices and telemedicine.

7. What users can do: best practices for protection

Although the greatest responsibility lies with institutions and organizations, the user can also contribute significantly to their own privacy:

  • Understand privacy settings: explore app menus, disable unnecessary location tracking or data sharing.
  • Use strong passwords and 2FA: a unique, hard-to-guess password and two-factor authentication better protect accounts.
  • Do not overshare on social networks: avoid sharing screenshots showing intimate health data.
  • Manage data synchronization: if apps offer to export data to other services, check if they are trustworthy to avoid new vulnerabilities.
  • Update software: regular updates prevent exploits already known to criminals.

8. The role of companies and organizations: building trust through accountability

The responsibility to protect health data does not rest solely on the individual. Data-collecting companies have a huge duty – both legally and morally. Their main actions are:

  • Privacy by design: data minimization and encryption must be integrated from the very start of product development.
  • Transparency: simplified documents or brief privacy summaries help users clearly understand data management, rather than overly legalistic Terms agreements.
  • Frequent security checks: third-party tests and bug bounty programs allow early detection of potential vulnerabilities.
  • Prompt breach notification: if a data leak occurs, the company must quickly inform both the relevant authorities and users so they can take appropriate action.
  • Ethical data monetization: if a company plans to sell or share user data, it must be done on an anonymous basis, allowing the user to opt out.

This fosters a user trust culture where company innovations do not come at the expense of user privacy.

9. Future changes: privacy-friendly technologies and trends

  • "Edge" data processing in wearable devices: Instead of sending data to the cloud, sensors will analyze information locally, sending only necessary summaries – reducing risk.
  • New encryption protocols: Systems are being developed where even companies cannot see real user data but only receive necessary results, protecting identifiable information.
  • Undeniable modification log / blockchain audit: In the future, we may see decentralized systems that record every data access – increasing transparency and preventing secret manipulation of records.
  • Legal reforms: As consumer demands for better protection increase, governments may develop stricter, consistent requirements to fill international gaps.

User awareness in this area will also grow, and demand for apps and devices that prioritize ethics and privacy will shape future technologies.

Conclusion

In the digital age, personal health and fitness data are both an opportunity and a potential threat – they can provide life-changing deep insights but also require serious measures to prevent misuse. By understanding the key privacy risks in wearable devices, health apps, or telemedicine platforms, users can make responsible decisions: limit data sharing, use strong passwords, and avoid questionable policies. Meanwhile, organizations handling this data must adhere to strict technical security and ethical use rules to earn trust and respect individuals' rights.

By properly balancing data-driven wellness and medical innovation, it is possible to offer remarkable benefits: earlier detection of issues, more personalized workouts, more effective chronic disease management, and deep population-level insights. However, it is essential that every step of data collection, analysis, and sharing is done informed, transparently, and using reliable security standards. As technologies rapidly transform healthcare, the most important task is to create a culture where innovation and privacy go hand in hand, ensuring consumer well-being and respect.
