Developer: Nathan Hopkins
App: Iron Gainz (iOS & iPadOS / iPhone Duo)

Executive Summary

Iron Gainz is built from the ground up with a 100% local-first privacy architecture. We believe your fitness journey, strength progressions, and workout history belong exclusively to you.

  • 100% On-Device Storage: All workout logs, routines, sets, weights, repetitions, and personal records are stored locally on your device using Apple's SwiftData framework.
  • No Account Required: No sign-up, login, email address, password, or profile creation is required to use Iron Gainz.
  • Zero Data Collection: We do not collect, transmit, store, rent, or sell any personal data or workout telemetry on external servers.
  • Zero Ads or Trackers: Iron Gainz contains no third-party analytics SDKs, advertising networks, or cross-app tracking technologies.

App Store Privacy Nutrition Label Summary

In accordance with Apple App Store Review Guidelines, Iron Gainz's privacy classification is:

Classification Details
Data Not Collected The developer does not collect any data from this app.
Data Not Used to Track You This app does not track you across apps and websites owned by other companies.

1. Information We Do Not Collect

Iron Gainz does not collect, transmit, harvest, or share any personally identifiable information (PII) or usage telemetry. Specifically, we never collect:

  • Personal Identifiers: Your name, email address, physical address, phone number, or Apple ID.
  • Device & Advertising Identifiers: Identifier for Advertisers (IDFA), vendor identifiers (IDFV), IP addresses, or browser fingerprints.
  • Location Data: Precise GPS coordinates, coarse location data, or Wi-Fi/Bluetooth beacon telemetry.
  • Biometric or Health Sensor Data: Facial recognition, fingerprint data, heart rate, or external biometric identifiers.

2. How Your Data Is Stored (On-Device SwiftData & AppStorage)

All information you enter into Iron Gainz is saved strictly inside the secure iOS/iPadOS application sandbox on your personal device:

  • Workout & Exercise Data: Custom workout plans, routines, exercise logs, completed sets, repetitions, weight values, exercise notes, and timestamps are persisted locally via Apple's SwiftData framework.
  • App Preferences: User interface preferences (such as Night Mode / Light Mode appearance, default rest timer durations, and auto-start timer toggles) are stored locally on your device using standard iOS UserDefaults (@AppStorage).
  • iCloud Device Backups: We do not operate any cloud servers or external databases. If you have Apple iCloud Backup enabled on your device, your local application sandbox may be included in your personal encrypted iCloud backup managed directly by Apple under your Apple ID settings and Apple's Privacy Policy.

3. Health & Fitness Analytics Integrity

Iron Gainz computes your estimated 1-Rep Max (1RM) progressions, total workout volume, set counts, and muscle group distribution metrics entirely on your device's processor in real time. None of your fitness statistics or performance history ever leave your device unless you explicitly choose to export them.

4. User-Initiated Data Export, Retention & Deletion

Because all data resides locally on your device, you have complete ownership and direct control over its retention, export, and deletion:

  • PDF Workout Reports & CSV Exports: Generating a PDF workout summary or exporting CSV workout statistics is initiated strictly by you. Exported files are rendered locally on your device and shared exclusively through the native iOS Share Sheet to destinations you select (e.g., Files, Mail, AirDrop, or Notes).
  • Granular Deletion: You can delete any individual workout session, set, or custom workout plan within the app at any time. Deleting an item immediately and permanently erases it from your device's local storage.
  • Complete App Removal: Uninstalling Iron Gainz from your device permanently deletes the local SwiftData database and all associated preferences from your device.

5. Third-Party Services & SDKs

Iron Gainz contains zero third-party software development kits (SDKs), external analytics services, crash-reporting frameworks, or advertising libraries.

If you have opted into "Share with App Developers" in your device's iOS Privacy & Security settings, Apple may provide anonymized system crash logs or aggregated App Store diagnostic metrics in accordance with Apple's standard platform terms.

6. Your Privacy Rights (GDPR, CCPA & Global Compliance)

Under privacy regulations such as the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA/CPRA), and similar global laws, users have the right to access, export, correct, and erase their personal data.

Because Iron Gainz never collects or stores your data on external servers, you can exercise all of these rights directly inside the app at any time:

  • Right to Access & Portability: View your full workout history in-app or export it anytime to CSV or PDF.
  • Right to Rectification & Erasure: Edit or delete any workout log, set, or custom routine directly within the app.

7. Children's Privacy (COPPA Compliance)

Iron Gainz does not knowingly solicit, collect, or process personal information from children under the age of 13 (or the applicable age of digital consent in your jurisdiction). Because the app collects zero personal data from any user, Iron Gainz fully complies with the Children's Online Privacy Protection Act (COPPA).

8. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect new app features or regulatory requirements. Any updates will be posted to this URL with a revised "Last Updated" date and reflected in the in-app Privacy Statement.
