A short, honest policy for a planning desk that stays on your table—and on your device.
GrainLine Sew Studio does not collect personal data. Measurements, Wearer Fit Cards, layouts, yardage settings, and cut sheets are calculated and stored on your device. There are no accounts, no cloud project sync operated by us, and no third-party analytics or advertising SDKs in the app.
If you export a file or open a share sheet, the destination you pick (Files, Mail, another app) is under your control. We do not receive those exports.
The core studio—blocks, yardage math, grain layout, and cut sheets—works on-device. The app does not phone home with your sewing data. Any link you open to this marketing site is ordinary web browsing outside the app’s project storage.
GrainLine Sew Studio is a general lifestyle calculation tool. It is not directed at children, and it does not collect personal data from anyone.
