1. Information Collection
CNC Workpiece Calculator does not collect or store any personal information, usage data, or device identifiers. The app runs entirely offline and never transmits your inputs to external services.
2. Use of Information
Because no data is collected, no data is used, processed, shared, or sold to any third parties.
3. Data Security
All geometry, tolerance, and weight calculations occur on your device. User inputs remain in local memory only for the duration of the session and are not persisted or synced.
4. Changes to This Policy
If the app’s functionality changes in a way that affects privacy, this page will be updated with the new policy and an effective date.
