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 DMC colours 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

DiamondZoid sets no cookies at all, and by default writes nothing to local storage, session storage or IndexedDB unless you ask it to. 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 DiamondZoid 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.

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

DiamondZoid carries no advertising, and loads nothing from any other site.

Children

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

Changes

Any revision will be published here. Questions to contact@sbsys.com.
