Using Stitchproof
Terms of use
These terms describe the use of Stitchproof, operated by Derek Zhang, an individual based in China. Contact: whitleylobalbo315@gmail.com. When an authorized representative accepts in the authenticated app, the merchant agrees to these terms, including our data processing terms, and acknowledges our privacy policy. Agreement version: 2026-10-06-v1.
What the service does
Stitchproof lets authorized Shopify merchants prepare embroidery proofs for order items, share private customer review links, record version-specific decisions and optionally organize changes with AI. It does not create machine stitch files, send customer messages automatically, manufacture products or authorize production.
Your responsibilities
You must have authority to access the store and to upload and process its content. Keep review links private, provide appropriate notices to customers and submit only information needed for the proof. You retain ownership of your content and permit us and the service providers listed in the privacy policy to process it to provide the requested service. Do not upload unlawful content, infringe others' rights or attempt unauthorized access.
Review text, spelling, line breaks, thread color, placement, size, quantity and artwork before publishing. Check the current Shopify order before production. A screen preview does not reproduce physical thread colors, stitch texture or dimensions. A recorded approval is a response to one item and version; it is not a guarantee of quality or a substitute for your agreement with the customer.
AI drafts
AI may make mistakes or overlook ambiguity. Check every suggestion before applying it. You can use the service without AI. AI requests are sent to MiniMax's China service endpoint as explained in the privacy policy.
Plans and billing
The free allowance is 20 newly published order-line proofs and 60 successful AI requests per shop in total; it does not reset monthly. Revisions of an existing item do not consume another new-proof allowance. Failed AI requests do not consume the successful-request allowance. Previously published proofs remain available for customer decisions when an allowance is exhausted, subject to valid links and store access.
Starter is offered at US$19 per month, with 100 new proofs and 300 successful AI requests per verified billing period. Availability and the exact price, renewal period, taxes and cancellation terms are shown on Shopify's confirmation screen before you accept a subscription. Eligible development stores use free developer test subscriptions. We do not collect payment-card details, and the free allowance alone does not authorize a charge. A subscription status or a $0 test does not prove payment was collected.
Manage available plans and cancellation through Shopify. The applicable Shopify confirmation governs the actual charge and billing period. Unused allowance is not a cash balance. Allowance exhaustion does not extend proof retention: on the current service, proof content remains subject to the 180-day per-order retention limit described in the privacy policy. Contact support for billing questions or refund requests; any rights required by applicable law remain available.
Availability and ending use
Access requires a valid Shopify installation and any applicable plan. Features and capacity may change, and service can be interrupted by maintenance or provider outages. Keep any independent records you need for your business before they expire or are deleted. Deleted proofs, artwork, messages, review links and approval and change histories cannot be restored from the app. You may uninstall through Shopify. Our privacy policy explains what happens to stored information. We may restrict access for misuse or security incidents.
Limits and changes
We provide the service with reasonable care, but cannot promise uninterrupted operation, error-free AI output or a particular business result. Nothing in these terms excludes rights or liabilities that cannot be excluded under applicable law. We will update this page when terms change and provide notice where required.
