Privacy Policy

Our Commitment to Privacy

StrengthMaxxer is designed with privacy as a core principle. Your workout data belongs to you, and we've built the app to keep it that way.

Data Collection and Storage

What We Collect

StrengthMaxxer stores your core training data locally on your device. This includes:

• Workout logs (exercises, sets, reps, weights)
• Custom exercise definitions
• Workout programs
• Personal records
• App preferences (units, rest timer settings, etc.)

Optional Cloud Features

StrengthMaxxer is local-first, but premium AI features can send limited training context to StrengthMaxxer's AI backend when you choose to use them. Progress Scan keeps raw photos on device by default. A cloud scan only uploads a selected photo after explicit consent, and temporary cloud images are deleted after analysis or retained only for a short cleanup window.

AI Coach and Progress Scan

AI Coach may process workout history, goals, constraints, and messages you provide so it can return a coaching summary. Progress Scan can summarize on-device photo signals locally; if you opt into a cloud scan or physique rating, the selected image and scan context are sent to our AI service for analysis. Requests are identified only by an anonymous app-generated ID — never a name, email, or account.

• AI features do not provide medical advice, diagnosis, or body-fat estimates.
• The physique scan returns subjective AI visual ratings of your physique presentation (including physique and aesthetics scores). These are the opinions of an AI model — not medical assessments, health scores, or body-composition measurements.
• Photo uploads are optional and require explicit action and consent in the app.
• Uploaded scan photos are deleted after analysis and never retained longer than 24 hours.
• You can delete cloud scan records from the app, which removes associated temporary cloud objects when present.

iCloud Sync (Optional)

If you enable iCloud sync, your workout data will be stored in your personal iCloud account. This data is:

• Encrypted end-to-end by Apple
• Accessible only to you and your devices
• Subject to Apple's Privacy Policy
• Not accessible to us in any way

You can disable iCloud sync at any time in the app settings.

In-App Purchases

Purchases are processed entirely by Apple through the App Store. We do not have access to your payment information. Apple may share basic transaction information with us (such as whether a purchase was made), but not your personal financial details.

Crash Reporting

We use Sentry for crash reporting to help improve app stability. Crash reports may include:

• Device type and iOS version
• App version
• Error stack traces

Crash reports do not contain any of your workout data or personal information. You can opt out of crash reporting in your device's Privacy settings.

Third-Party Services

StrengthMaxxer integrates with the following third-party services:

• Apple (App Store, iCloud, StoreKit): For app distribution, optional cloud sync, and in-app purchases
• Sentry: For crash reporting and app stability monitoring
• Cloudflare:For hosting StrengthMaxxer's AI API, usage credit records, and temporary cloud scan storage
• Alibaba Cloud (Qwen):For AI Coach text generation and physique scan photo analysis when you request them. Requests are processed in Alibaba Cloud's international (Singapore) region, solely to produce the response or analysis you asked for. Alibaba Cloud states that customer data is not used for model training.

We do not sell your personal data. Optional AI feature processing is limited to operating the feature you request.

Data Deletion

You can delete all your data at any time by:

• Using the "Delete All Data" option in app settings
• Using "Delete AI Data" in Settings → Data & Privacy, which permanently deletes everything our AI server stores for you (coach request history, scan records, usage data, and any retained scan images) and resets your anonymous AI identity
• Uninstalling the app (this removes all local data)
• Deleting app data from iCloud (if sync was enabled) through your device's iCloud settings

You can also email privacy@strengthmaxxer.com to request deletion.

Children's Privacy

StrengthMaxxer is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us so we can promptly remove it.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
