Terms of use

PatternGrade Sewing is provided by Gobling Company. Apple’s standard Licensed Application End User License Agreement applies to App Store use.

Purchase

Paid upfront, without subscription or in-app purchases. The App Store region governs price and refund handling.

Your patterns

You retain rights in your material. Import and share only content you own or may use. The optional example is an original straight-segment study, not a fitted sewing pattern. The tool does not certify fit, seam matching or manufacturing tolerances. Curve hints and seam allowances are records, not generated curves or added offsets. Check measurements, print calibration, fit and production details independently.

Local storage

There is no developer cloud recovery. Device failure, app removal or deletion can lose local work. Keep independent JSON backups and exports. Contact maga40@naver.com.
