Privacy Policy

Last updated: July 14, 2026

CNC Setup Sheet (the “App”) respects your privacy and is committed to protecting your personal information. This Privacy Policy explains what information the App handles.

1. Data stored only on your device

Everything you enter or create in the App is stored only in local storage on your device. It is never transmitted to our servers or to any external party. The developer does not collect any personal data and the App requires no account or sign-in.

  • Saved calculations (the inputs and results you choose to keep in History)
  • Setup sheets (job header — part, machine, workholding, WCS, coolant — tooling and cut data, operation sequence, setup notes)
  • App settings
  • Pro purchase status

This data is removed from the device when you uninstall the App.

The App’s backup feature can export the data above into a single file. Where that file goes — on-device storage, iCloud Drive, another cloud service — is entirely your choice, and the developer never receives its contents.

2. Device features and permissions

The App does not use the camera, photo library, location, contacts, or any other special device permission.

3. Anonymous usage analytics and crash diagnostics

For quality improvement and bug fixing purposes, the App sends the following anonymous information to Google’s Firebase Analytics and Firebase Crashlytics. None of the content you enter in the App — calculation inputs, setup sheets, notes, settings — is included in this data.

  • Screen transitions and counts of key feature usage (e.g. running a calculator, creating a setup sheet, exporting a PDF, creating or restoring a backup)
  • Anonymous environment information such as device model, OS version, app version, and region
  • When the App crashes, the crash stack trace and a short trail of preceding actions (Crashlytics)
  • App instance identifier — an anonymous ID generated per device. The advertising identifier (IDFA) is not collected.

This data is never collected or used in a personally identifiable way. If you prefer not to share it, open the App’s Settings screen and turn off “Allow anonymous usage stats” at any time.

4. No sharing with third parties

The App never provides the content you store on your device to any third party.

5. In-app purchase (Pro)

The Pro upgrade is processed through Apple’s App Store In-App Purchase system. Your payment information is managed by Apple, and no personal details (name, card number, etc.) are ever shared with the developer. The App only receives confirmation that the purchase completed and stores a single “Pro is active” flag on your device.

6. Children’s privacy

The App is a utility for machinists and workshop use and is not directed at children. We do not knowingly collect information from children under 13.

7. Changes to this policy

This policy may be updated from time to time. Significant changes will be announced on this page.
