1. Who We Are
PlateMaths is a local-first barbell plate calculator and training workflow app. It helps users calculate plate loading, save equipment setups, keep favorite loads and recent sessions, and continue faster through widgets.
For privacy-related questions, contact:
- Support email:
ironfuel.support@naxs.top
2. Information We Collect
The current version of PlateMaths does not require account registration. Information you enter or generate in the app may include:
- Plate calculation data such as target weight, bar weight, units, plate inventory, per-side loading results, and percentage training loads
- Equipment setups for different training places, including bar weights, plate inventory, and display style
- Favorite loads, percentage templates, recent calculation sessions, and quick workflow entries
- App preferences such as language, units, display choices, onboarding state, and Pro entitlement state
- Widget data such as recent loading snapshots, favorite entries, and training summaries
3. How Information Is Stored
PlateMaths is designed to work locally first. Core data is stored on your device by default. Some data is stored in the app group so the main app and widgets can share it.
In the current version:
- No account is required
- Workout or loading data is not stored on a developer-operated server
- The free version remains local-only
- Pro users may manually enable iCloud sync for equipment setups, favorites, and history
iCloud sync is handled by Apple’s iCloud / CloudKit infrastructure. The developer does not operate a separate server to read or store your training data.
4. How Information Is Used
Information is used only to:
- Calculate and display barbell plate loading results
- Save equipment setups, quick entries, percentage workflows, and recent history
- Show recent loads, favorites, and training summaries in widgets
- Determine and restore your Pro entitlement
- Improve app stability, usability, and on-device experience
5. In-App Purchases
Pro features are provided through Apple’s App Store in-app purchase system and are designed as a lifetime Pro unlock. Payments, refunds, and billing information are handled by Apple. The developer does not receive your full payment card details.
6. Third-Party Services
Currently, PlateMaths does not use third-party advertising SDKs, does not provide targeted advertising based on personal data, and does not require third-party login services.
If a future version introduces third-party services that materially change data handling, this policy will be updated.
7. HealthKit
Currently, PlateMaths does not integrate with Apple HealthKit and does not read from or write data to the Health app.
8. Sharing, Sync, and Deletion
You can stop retaining related data by deleting the app, clearing local data, removing widget shared data, or disabling and deleting iCloud data associated with this app.
If you actively screenshot, copy, or share data to another app, the shared content is handled according to the destination you choose.
9. Children’s Privacy
PlateMaths is not specifically directed to children. If you believe data has been collected inappropriately, contact us and we will review the issue.
10. Updates
We may update this Privacy Policy when the app’s features or data handling practices change. The updated version becomes effective on the new effective date shown above.
