Privacy Policy

Nothing you open here is sent anywhere. The conversion runs on your own device.

Your photographs

Reading the file, cropping, resampling, reducing colours and matching them to threads all happen inside your browser. The image stays in memory while the tab is open and is gone when you close or refresh it. It is never transmitted, so we never hold it and never see it.

Saved chart files are written by your browser to your own device. They contain the grid, the palette and the settings, and deliberately not the photograph, so you can pass a chart to a friend without passing on your picture.

Cookies and browser storage

StitchZoid sets no cookies at all, and by default writes nothing to local storage, session storage or IndexedDB. That covers the advertising script described below as well as the pattern tools themselves: unless you ask it to, it stores nothing on your device, and it is sent no cookies when it fetches an advert. There is no sign-in, no account and no profile, so there is nothing about you for us to store.

The one exception is a switch you turn on yourself: Keep this draft on this device, on the pattern screen. While it is on, your browser keeps a copy of the pattern in its IndexedDB storage — the chart, the palette, the settings and the pattern's name, the same things a saved pattern file holds — so a refresh or a closed tab doesn't lose your work. It never holds the photograph, and it never leaves your device. Turning the switch off, or choosing Discard when StitchZoid offers the draft back, deletes it; so does clearing this site's data in your browser.

Analytics

There is no analytics package and no tag manager. Nothing here measures or reports what you do with the site — not which photograph you chose, which settings you picked, or whether you exported anything. The one thing reported off the page is whether the advert was actually on screen, described next.

Server logs

Hosting is Cloudflare Pages, which records the usual web server details — IP address, timestamp, user agent — to serve the site and defend it. Those logs are not combined with anything else or used to work out who you are.

Advertising

StitchZoid carries one advert, served by AppRing. It sits beside the legend on the pattern screen, in a fixed place chosen by us, and it is the only one: nothing is injected automatically, and the upload and setup screens carry no advertising at all. Nothing is requested from the advertising network until you reach the pattern screen, so simply visiting the site contacts nobody. Google AdSense is no longer loaded here.

The advert is plain text — an emoji, a headline, a line or two, and a link. There is no image, no iframe and no tag of its own inside it, so it cannot load anything further or watch the page around it.

To fill the slot, the page asks api.appr.ing for an advert. That request carries no cookies and nothing identifying; like any request to any server, it does reveal your IP address, your browser’s user agent and the page you were on. Once the advert has been at least half on screen for a second, the page sends AppRing a short note saying so, so that an advertiser is billed for adverts people actually saw. That note says only which advert was shown. It is the only thing this site sends anywhere about your visit.

The advert is not personalised. Nothing about you is sent, nothing is stored on your device, and nothing here builds a profile of you.

Block it with any content blocker if you would rather not have it — or if the network is simply unreachable, which comes to the same thing. The slot collapses to nothing and the pattern tools work identically, because they never depended on it.

Children

The site is not directed at children under 13 and gathers no personal information from visitors of any age.
