Privacy
This tool has no in-app account, payment, license-key gate, or cloud image conversion. Image conversion happens entirely in your browser.
Images and patterns
Images you choose are decoded, converted, and exported in your current browser. This tool does not send source-image pixels to the server. Draft recovery stores grid cells, color codes, dimensions, and view settings, but not the reference image.
Project files
An editable JSON project contains its title, cell color codes, and settings, but does not embed the reference image. Check the project title before sharing so it does not reveal a name, order number, or other private information.
Hosting providers
When you visit this site, the hosting provider may process IP addresses, user agents, request times, and security logs under its own privacy policy. If third-party advertising or analytics are added, those providers may use cookies and process related data under their own policies. Image conversion itself never uploads your source image.
Your control
You can clear recovery data inside the app or clear the browser's site data. Local storage can disappear in private browsing, after browser cleanup, or because of device failure, so save important work as a JSON project backup.
