3D Nozzle MM to IN Helper ("we", "our", or "the app") is an offline utility for converting 3D printer nozzle diameters between millimeters and inches. This page explains what information the app accesses and how it is handled.
The app does not require an account, login, or profile. We do not collect personal information, conversion history, contact information, or device identifiers through the app.
All conversion logic runs locally on your device. Presets, copied values, and any convenience state remain on-device and are not sent to a remote server.
The optional Parts section contains links that open Amazon product pages in your browser. If you choose to follow those links, Amazon may collect information under its own policies. Purchases happen outside the app.
The app does not use advertising SDKs, analytics SDKs, or cross-app tracking services.
Because app data is stored locally on your device, you can remove it at any time by deleting the app.
We may update this policy from time to time. The date above reflects the latest revision.
If you have questions about this privacy policy, contact us at craft.spicier.6j@icloud.com.
