Privacy Policy

StitchMargin is an offline-first business quoting utility published by YunFanLabs.

• The app does not require an account.
• The app contains no advertising or third-party analytics SDKs.
• DST files, customer details, shop logos, quote values, and usage data are not sent to YunFanLabs servers.
• DST parsing, price calculation, history storage, and PDF or image generation run on the device.

The app may store information that you enter or select in its local container. YunFanLabs does not receive it through the app.

• Shop name, logo, contact details, address, tax rate, payment instructions, notes, and terms.
• Pricing templates, product types, fees, discounts, and cost inputs.
• Customer and project information used in a quote.
• Parsed DST metadata and a simplified stitch preview.
• Quote history, generated file references, settings, and onboarding state.

You may choose a DST file through Apple's document picker or open it from another app. StitchMargin reads the selected file locally to calculate supported design statistics and does not upload it.

You may choose a shop logo through Apple's system photo picker. The selected image is processed and stored locally; the picker does not grant general photo-library access.

If you choose Save Image, the app requests add-only Photos permission to save the generated quote image. StitchMargin does not request camera access.

PDFs, quote images, summaries, and information you deliberately share are passed to the destination you select through Apple system interfaces. Files saved or shared outside the app are then handled under the destination service's privacy practices.

Shop settings remain until you clear or replace them, or uninstall the app. Quote data remains until you delete the relevant record or uninstall the app. Deleting a quote removes its app-managed history data and associated generated files. StitchMargin cannot delete copies already exported outside the app.

The current version does not collect data for tracking, advertising, analytics, or sale. It has no YunFanLabs account, cloud database, or server-side processing service.

Apple may process App Store purchase, download, crash, and diagnostic information under Apple's own terms and privacy policy. YunFanLabs does not control Apple's platform-level processing.

StitchMargin is a business utility and is not directed to children. The app does not knowingly collect children's personal information through a publisher-operated service.

StitchMargin uses standard iOS storage and file-protection mechanisms. No storage method is risk-free. Protect your device and review customer information before exporting or sharing it.

If a future version materially changes how information is handled, this policy will be updated before or with that release.
