Privacy Policy
DuealDraft is a local drafting application. Your gasket projects, material presets, geometry, exports, and preferences are stored on your device. We do not operate user accounts, cloud sync, or analytics services inside the app.
Information we process
Content you create — including project names, dimensions, notes, and exported files — remains under your control on the device. If you use system share sheets or Files to send a PDF, SVG, PNG, or JSON backup, that transfer is handled by iOS and the destination you choose; DuealDraft does not receive a copy.
Data retention
Data persists until you delete projects, reset the library from settings, or remove the app. Uninstalling DuealDraft removes locally stored app data from the device subject to iOS behavior.
Children
DuealDraft is not directed at children under 13. We do not knowingly collect personal information from children.
Changes
We may update this policy to reflect product or legal changes. The effective date of the latest version will be noted on this page when updated.

Support
DuealDraft provides geometric drafting tools and material estimates. It does not certify sealing performance, pressure resistance, chemical compatibility, or suitability for safety-critical applications. Verify dimensions, materials, and application requirements before manufacturing or installation.
Getting help
For questions about features, exports, or troubleshooting, email nataliabuzhyna@nisanatradellc.org with your device model, iOS version, and a short description of the issue. If reporting an export problem, include whether you printed at 100% scale and verified the calibration mark.
Printing templates
PDF templates are generated at physical scale when you choose 1:1 export. Printer scaling varies by model and driver. Disable “Fit to Page” or automatic scaling and measure the calibration reference before cutting.
