Privacy by design

Your artwork stays on your Mac.

Last updated July 16, 2026

Local processing

StitchPlot reads source images, generates charts and calculates palette and thread estimates locally on your Mac. The core app does not require an account or upload your artwork to Shipmac.

Encrypted project storage

The app encrypts its local project archive with authenticated encryption and keeps the encryption key in macOS Keychain. You remain responsible for protecting your Mac account and exported files.

Exports

StitchPlot writes PDF patterns, shopping lists, project JSON, manifests and backups only when you request them. Source images remain untouched.

Website and checkout

This website may produce ordinary server access logs. Purchases are processed by Polar as merchant of record under its own privacy terms. Shipmac receives the purchase details needed to deliver and support the app; payment-card details are not handled by the app.

Contact

Privacy and support questions can be sent to support.app.

Website analytics

This website loads Google Analytics only after you choose Allow analytics. When enabled, Shipmac measures page visits, the product hostname and checkout starts; it does not send files or content processed by the Mac app. You can change your choice at any time using Analytics choices.
