Privacy

• No accounts, no cookies, and no ad trackers. Visits are counted anonymously.
• Photos are never stored, and only a small preview of your crop leaves your browser. It may be sent for a color check, and isn't kept.
• Your last thread list is kept in this browser, and only here, so you can come back to it. It holds thread numbers, not your photo.

When you choose or take a photo, your browser decodes it, crops it, and extracts the colors itself. The full photo is never uploaded. It is discarded when you start over, reload, or leave the page.

So a reload or a closed tab doesn't lose your list, Threadwise keeps the last one in your browser's local storage: the matched thread numbers and colors, your canvas size and mesh count, and what you ticked off in the store checklist. It never includes your photo or its preview, and it is never sent anywhere.

It stays until a new list replaces it. To remove it, choose Forget on the home page or clear this site's data in your browser. Clearing site data also forgets the mesh count Threadwise remembers for your next canvas.

When it is turned on for this site, Threadwise double-checks the colors it found before showing your list: it leaves out blank canvas, the mesh's shadows, and glare, and adds colors the scan missed. The same check suggests stitches on the Plan step when you ask for them.

It sends a JPEG preview of your crop, no larger than 512 pixels on its longest side, and the list of extracted colors (on the Plan step, a description of the canvas's main areas). They travel from our server through the Vercel AI Gateway to an AI model provider, which returns its answer. Threadwise does not store the preview or the answer. The model provider's own terms cover how it handles requests.

To limit how often the check can run, your IP address is held briefly in server memory. It is never written to disk.

The Shop menu opens a retailer's own site in a new tab, where its privacy policy applies. The links currently carry no tracking or affiliate codes. Copy list writes to your clipboard only when you click it.

Like any website, the servers that host Threadwise may keep standard request logs, such as IP address, time, and page requested, for security and reliability.

To see which pages people use, Threadwise counts visits with Vercel Web Analytics. It sets no cookies and doesn't identify you: it records the page, the referring site, your browser, operating system, device type, and country. Your photo, crop, and thread list are never part of it.
