Summary
CNC Machinist Tools is an offline machining-calculation app. This Privacy Policy explains how the app handles information when you use it.
- The app does not require an account.
- The app does not operate a remote API, user database, analytics service, advertising service, or CloudKit sync.
- Your calculation inputs, results, history, favorites, settings, and machine profiles are stored locally on your device.
- Purchases are processed by Apple through the App Store. We do not receive or store your payment-card information.
Information the App Stores Locally
The app stores the following information locally on your device so that its features work:
- Calculation inputs and results, including saved calculation history and favorites.
- App preferences, such as your default unit system and fractional-inch display preference.
- Machine profiles and limits that you create.
- The local state needed to reflect an active Lifetime Pro entitlement.
This information is not sent to our servers because the app does not operate a server or remote account system.
Purchases
Lifetime Pro is a one-time, non-consumable in-app purchase. Purchase processing, payment information, and Apple Account information are handled by Apple under Apple's own terms and privacy practices. The app uses Apple's StoreKit service only to determine whether a valid Lifetime Pro entitlement is active. We do not collect or store your payment-card details.
Information We Do Not Collect
The app does not collect or use the following information for its own purposes:
- Your name, email address, phone number, or contacts.
- Precise location.
- Browsing history.
- Advertising identifiers or cross-app tracking information.
- Usage analytics, crash analytics, or advertising data.
- Your machining inputs or calculation results on a remote server.
Device Backups
The app does not provide its own cloud synchronization or CloudKit storage. Your device may include app data in an Apple device backup depending on the settings you choose for your device and Apple Account. Those backups are controlled by Apple and your device settings.
Your Choices and Data Deletion
You can delete individual calculation-history entries, favorites, and machine profiles from within the app. You may also remove the app from your device to remove its locally stored app data, subject to any device-backup settings you have enabled. We cannot retrieve or restore your local calculation data because we do not keep a copy on our servers.
Children
The app is not directed to children and does not knowingly collect personal information from children.
Changes to This Policy
If the app's data practices change, we will update this Privacy Policy and revise the effective date above.
