Terms & privacy
Last updated September 7, 2026.
Your custom build
The $79 offer covers one agreed CSV input format, one output format, and up to ten transformation rules. We confirm feasibility, required samples, and delivery deadline before payment. Delivery is within 24 hours after accepted scope, payment, and complete requirements.
Delivery and use
You receive a downloadable HTML tool, sample input and output, and instructions through the contact channel agreed with you. You may keep, modify, and use your delivered tool for your own business workflows. The reusable underlying engine remains available for other Columncraft builds. The tool does not update your store or guarantee compatibility with formats beyond the agreed sample and rules.
Revisions and refunds
One revision within the agreed scope is included when requested within seven days of delivery. If we cannot deliver the agreed functionality, we offer a refund. New input formats or workflows require a separate agreement. Contact us through your order conversation for a revision or refund request.
Data and privacy
CSV input and conversion results stay in browser memory and are not uploaded by the tool. Closing or refreshing the page clears them. Downloaded files remain on your device until you delete them. The offline tool makes no network requests.
The request form creates a local brief. If you choose to send it, your email application sends your name, reply email, and workflow details to the seller. Do not share confidential or personal customer data; use anonymized samples. Details received are used to scope, deliver, and support your order. Request deletion of samples through your order conversation; transaction records may need to be retained.
Hosting providers process normal website requests, including technical access information. There is no advertising tracking added by Columncraft. Stripe processes payments under its own privacy terms. We do not receive your full card details.
