Images and patterns
When you upload an image, it is sent for conversion into your pattern. The image is processed for that request and is not kept as an uploaded file on our servers. You can view the original image while the page is open.
The homepage keeps a temporary copy in this browser while opening the pattern maker. It is removed when the pattern maker reads it. Unused copies expire after ten minutes and are cleared the next time you upload an image.
Resize, print, yarn calculations and material selections run on your device. Downloaded files are stored wherever you choose to save them.
Saved projects
The save action keeps up to ten pattern projects in this browser on this device. A saved project contains the editable pattern rather than your original uploaded photograph.
Export a project file to move it to another device. Clearing this site's browser data removes the saved projects; download anything you want to retain first.
Site access and external links
Hosting services process requests needed to deliver the website, which can include your IP address and basic request information. This site does not provide user accounts or send your uploaded images to an advertising service.
Learning-resource links open other providers' websites. Their privacy practices apply when you visit them.
ChatGPT and Claude app
The Punchneedle.ai app in ChatGPT and Claude is read-only. It sends only the inputs given to a tool, such as an image address, a size or a material, to this website's own calculations. For a pattern made from an image, the image is read once to make the pattern and is not kept. A result link opens the matching page on this site with those inputs filled in. The app keeps no record of questions, images or accounts, and it records no click on its links.
