Privacy Policy
Thread & Grid is operated independently by Yifei Huang. Questions about this policy can be sent to privacy@threadandgrid.com.
Your pattern content stays in your browser
The pattern maker processes the image or text you select in your browser. We do not send your source image, typed text, generated grid, settings, file name, or exported file to our analytics service.
Anonymous usage measurement
We use a privacy-focused analytics service to understand aggregate visits and whether the core tool works. It receives the page's canonical address, the referring page, and limited technical information used for aggregate browser, device, and country reports. We remove query parameters and URL fragments, except that we retain the fixed campaign marker utm_source=chatgpt.com when present to measure ChatGPT referrals. We record only three tool events: Pattern Generated, PNG Exported, and Print Requested. Each event includes only whether image or text mode was used.
Analytics is disabled when your browser sends Do Not Track or Global Privacy Control. We do not use advertising cookies or build advertising profiles.
Hosting and security
Cloudflare provides hosting and security and may process limited request information such as IP address, browser type, and request time to deliver and protect the site. Our analytics provider processes the limited usage information described above.
Accounts, payments, and storage
This version has no account system, cloud project storage, payment flow, or advertising. Because we do not keep pattern content on our servers, we cannot retrieve or delete a cloud copy of your image, text, chart, or exported file.
Your choices and changes
You can enable Do Not Track or Global Privacy Control, close the page, or clear your browser data at any time. We may update this policy when the service changes; the effective date above identifies the latest version.
