Health-Data Compliance & Privacy for Fitness Apps
Start with the rules that apply to your situation, then move to the build practices. If you’re still choosing infrastructure, an aggregator or an on-device approach can change how much regulated data you touch in the first place. For the consent mechanics, see OAuth for health data.
Which rules apply to you
Figure out your obligations before you write a line of code.
- Does My Fitness App Need to Be HIPAA Compliant?Most direct-to-consumer fitness apps aren't HIPAA covered. Learn when HIPAA applies, when it doesn't, and what rules apply instead.
- GDPR for Fitness Apps: What Developers Need to KnowDoes GDPR apply to your fitness app? How EU rules treat wearable data as health data, plus lawful basis, consent, and core obligations for developers.
- Does the FDA Regulate Fitness Apps?Most fitness and wellness apps fall under the FDA's general wellness policy, not device rules — unless you claim to diagnose or treat a disease.
- Is Fitness Data PHI? PII, PHI, and Health Data UntangledUsually not. PHI is a HIPAA term tied to who holds the data. The same reading can be PHI, GDPR health data, or consumer health data by context.
Platform requirements
What Apple and Google require to ship a health app.
- Apple App Store Health Data Rules: What You Need to Ship a HealthKit AppWhat Apple requires to ship a health app or use HealthKit: privacy policy, no ads or data selling, in-app account deletion, and more. Verify sections.
- What does Google Play's health data policy require?What Google Play requires for health apps and Health Connect: permitted uses, no ad use, prominent disclosure, the Data safety form, and deletion.
Building it right
Consent, storage, retention, and the policy users actually read.

- How to Get Valid User Consent for Health DataHow to get valid consent for health data under GDPR: opt-in, granular, withdrawable. Why an OS permission is not legal consent, plus consent to sell.
- What Does a Fitness App Privacy Policy Need to Include?What a health or fitness app privacy policy must cover, from data collected and legal basis to user rights, and why it must match your real practices.
- Health Data Retention and Deletion: A Developer's GuideHow long can a fitness app keep health data, and how do you delete it? GDPR storage limitation, the right to erasure, and in-app deletion, explained.
Frequently asked questions
- Does my fitness app have to be HIPAA-compliant?
- Not automatically. HIPAA applies when you're a covered entity (a healthcare provider, health plan, or clearinghouse) or a business associate handling protected health information on one's behalf. A direct-to-consumer fitness app that a user installs themselves is usually not covered by HIPAA — but it is still subject to other rules (GDPR, state privacy laws, the FTC Health Breach Notification Rule, and app-store policy). Where you sit determines everything else, so start with the HIPAA and 'is this data PHI' pages.
- Is heart rate or step data considered sensitive?
- Often, yes. Under GDPR, data 'concerning health' is a special category needing a stronger legal basis, and regulators have treated fitness and wearable data as health data in many contexts. Under HIPAA the label 'PHI' depends on who holds it and why, not just what it is. The practical takeaway: treat wearable and workout data as sensitive by default, and read the 'is fitness data PHI or PII' page for the distinctions.
- What's the minimum I need before launch?
- At a minimum, most health apps need: a clear, accurate privacy policy; a lawful basis and genuine consent for collecting health data; secure storage (encryption in transit and at rest, access controls); a way for users to export and delete their data; and compliance with Apple's and Google's health-data rules if you ship on their stores. Each is covered in its own page below. This is general guidance, not legal advice — confirm specifics for your jurisdiction and product.

Health-data laws (HIPAA, GDPR, state privacy laws) and platform policies vary by jurisdiction and change often, and how they apply depends on your specific product, users, and data. Confirm your obligations with a qualified attorney or compliance professional and check the current official sources before you ship.
