Privacy Policy
Last Updated: February 4, 2026
Summary: StrengthAI is designed for privacy. Your workout and Health data stays on your devices.
We do not sell personal data. We do not upload Apple Health / HealthKit data to our servers.
Who we are
StrengthAI ("we," "our," or "the app") provides training apps for iPhone and Apple Watch.
What this website collects
This website may offer a waitlist or contact form from time to time. When enabled, we may collect your email address
to send beta invitations or product updates. If the waitlist is closed, the site may not collect any personal
information beyond basic security logs your hosting provider maintains to protect the site.
- Email address (when a waitlist/contact form is enabled) to respond or send updates.
- Basic security logs (e.g., IP address, request metadata) may be processed to protect the site from abuse.
What the app collects (on your device)
Health and fitness data (optional)
With your explicit permission, StrengthAI can read certain Apple Health / HealthKit data to power workout displays,
analytics, and insights. You control access at all times.
HealthKit data we may read (with permission):
- Heart rate during workouts
- Workout sessions and history
- Active energy burned
- Distance traveled (for cardio activities)
- Sleep data
- Nutrition information (energy intake and macros)
- Body measurements (weight, body fat percentage)
- Cardiometabolic signals (HRV, VO₂ Max, resting heart rate)
HealthKit data we may write (with permission):
- Completed workout sessions
- Workout duration
- Active energy burned during workouts
- Distance traveled during cardio exercises
Location data (optional)
With your permission, StrengthAI may access your location to track distance and pace during outdoor cardio workouts
(running, cycling, walking), provide GPS-based distance measurements, and calculate elevation gain.
Workout data you enter
StrengthAI stores workout-related data locally on your device, such as:
- Workout templates you create
- Exercise routines
- Sets, reps, and weights logged
- Workout history and progress
- Personal records (PRs)
How we use information
- Display live workout metrics (e.g., heart rate, calories, distance).
- Generate progress reports and performance insights.
- Track fitness progress over time and support recovery-aware recommendations (when enabled and available).
- Sync workouts between iPhone and Apple Watch using Apple's secure frameworks.
- Operate and secure the website (including abuse prevention).
Data storage and security
- Local storage only: Health data and workout data remain on your devices. We do not upload Apple Health / HealthKit data to our servers or cloud services.
- Device sync: Data may sync between iPhone and Apple Watch via Apple's WatchConnectivity framework.
- No selling of data: We do not sell, rent, or trade personal information.
On-device AI (when available)
If your device supports on-device AI features, you may be able to ask questions about your workout and Health data.
AI processing happens on your device. No Health data is sent to external AI services for this feature.
Sharing
We do not share your Apple Health / HealthKit data with third parties. If we use service providers for basic website
operations (for example, email delivery when a waitlist is enabled), those providers may process limited data under
our instructions and appropriate safeguards.
Your controls
- Health permissions: You can change or revoke permissions anytime in the Health app (Sources).
- Location permissions: You can change location access anytime in iOS Settings > Privacy & Security > Location Services.
- Data deletion: You can delete workouts inside the app. Deleting the app removes locally stored app data. Health data written to Apple Health remains in Health unless you delete it there.
Data retention
- Workout data is stored on your device until you delete it.
- Health data access is governed by your Apple Health permissions.
- If a waitlist is enabled, emails are kept until you unsubscribe or the beta program no longer requires them.
Children's privacy
StrengthAI is not directed to children under 13 and we do not knowingly collect information from children under 13.
Changes to this policy
We may update this Privacy Policy from time to time. The "Last Updated" date at the top indicates when it was last revised.
Continued use of the app or website after changes constitutes acceptance of the updated policy.
