PatternPlot

Terms of Use

Effective date: 10 July 2026 · Last updated: 14 October 2026

These Terms of Use ("Terms") govern your use of the PatternPlot app ("the App"), published by cpmtek ("we", "us"). By downloading or using the App you agree to these Terms.

1. Apple standard license

Your license to use the App is also subject to Apple's Licensed Application End User License Agreement (the standard Apple EULA). Where these Terms add to that agreement, both apply; where they conflict on a consumer-protection point, the term more favourable to you governs.

2. What the App does

PatternPlot lets you trace paper sewing patterns into editable, true-scale vector pieces; add seam allowance, notches, and grainlines; deterministically grade a base size into a run of sizes; and export true-scale tiled and A0 PDFs. Grading geometry is computed deterministically on your device.

3. Verify before you cut — grading disclaimer

PatternPlot is a drafting and grading tool, not a guarantee of fit. Graded sizes, seam allowances, notches, and exported measurements are aids that you are responsible for checking. The App flags when a size drifts beyond a safe grade range, but you must verify graded patterns — and print a test / calibration square at 100% scale — before cutting fabric or putting a pattern into production. We are not liable for wasted material or production loss arising from unverified output.

This version of the App has no AI feature. The deterministic engine on your device is the source of truth for every coordinate, seam allowance, notch, and graded measurement, and no AI sets or alters any of them.

4. Free features and Pro Grading subscription

Tracing, vector editing, seam allowance, notches, grainline, and tiled/A0 PDF export are free and do not require a purchase. So is grading your own piece across a size run you define: the nested run and the quality report are shown on screen, and the base size — the size you drafted — exports free. Pro Grading buys the files for the rest of the run: a tiled PDF of every size, a nest of the whole run (on one sheet), a vector outline of every piece, a spreadsheet of what every declared seam measured and your grade corrections saved to a file, with every piece of the garment in each file.

Pro Grading is an auto-renewable subscription:

Title / length: Pro Grading, 1 year.
Price: US$79.99 per year, after a 7-day free trial for new subscribers (prices in other regions are shown in the App at purchase).
Payment is charged to your Apple ID at confirmation of purchase.
The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your Apple ID is charged for renewal within 24 hours before the period ends.
You can manage or cancel the subscription, and turn off auto-renew, in your Apple ID Account Settings after purchase. Deleting the App does not cancel a subscription.
Any unused portion of a free trial is forfeited when you purchase a subscription, where applicable.

Purchases and subscriptions are processed by Apple; refunds are handled under Apple's policies.

5. Your content

Your patterns are yours. The App stores your work locally on your device; we claim no ownership of your patterns and do not store them on our servers. You are responsible for having the rights to any pattern or image you trace.

6. Acceptable use

Do not reverse engineer, resell, or misuse the App, and do not use it to infringe others' rights.

7. No warranty; limitation of liability

The App is provided "as is" to the fullest extent permitted by law, without warranties of fitness for a particular purpose. Nothing in these Terms limits liability that cannot be limited under applicable law, including your statutory consumer rights. Subject to that, our aggregate liability arising from the App is limited to the amount you paid for it in the 12 months before the claim.

8. Changes

We may update these Terms; we will change the effective date above and, for material changes, surface a notice. Continued use after a change means you accept the updated Terms.
