Privacy

Your photo is processed entirely inside your browser. It is never uploaded to us or to anyone else. This page explains precisely what that means, and what little the site does keep.

Last updated 20 October 2026.

Your photo never leaves your device

When you choose a photo, it is decoded and resized by your own browser and held in memory for as long as the page is open. Every measurement, every render and every edit happens there. No server ever receives the image, and nothing the site sends anywhere includes it.

The photo is not saved to your device either. It is deliberately excluded from the settings the site stores locally, so closing the tab discards it. If you reload, you will be asked for it again. That is intentional rather than an oversight.

Using a bank card as a ruler

One way to calibrate is to lay a bank or ID card next to your hand. That works because such cards are a fixed size worldwide — 85.60 × 53.98 mm under ISO/IEC 7810 — which makes one a very accurate ruler.

That photo is handled exactly like any other: read in your browser, used only to measure distances, never transmitted, never stored, and never read for card numbers or any other card details. The site takes no payments of any kind.

What is stored on your device

The site keeps your settings in your browser's local storage so they survive a reload. That data stays on your device. The only things from it that are ever counted, anonymously and as described under “Cookies, accounts and tracking”, are a stone's shape, its weight to the nearest quarter carat, and which of the three ways the scale was set. Never your ring size or any measurement. It covers:

You can clear all of it at any time by clearing site data for this domain in your browser.

Cookies, accounts and tracking

There are no cookies, no accounts, no sign-up and no email collection. Your photo, your hand's measurements, your ring size and the names you give stones are never transmitted.

The site counts page views using Cloudflare Web Analytics. It sets no cookie, writes nothing to your browser, and does not build a profile or follow you to other sites. It records the page, the referring site, and coarse details like country and device type. It cannot see your photo, your measurements, or anything you type.

The tool also counts which of its steps get used, so we can tell whether it works for the people using it: how the visit arrived and whether it is on a touch screen; that the opening walkthrough played and whether it was watched to the end; that a stone was chosen, with its shape and its weight to the nearest quarter carat; that a photo of your own was added — never the photo itself; which of the three ways the scale was set; whether “Find my finger” found a finger; that an image was saved or a link copied; and when one of those steps failed. The counts go to this site, not to anyone else, with no cookie and no identifier: nothing links one visit to another, and the address a count came from is not stored with it.

Following a link to a retailer

Where the tool suggests retailers who sell a shape, the link passes through a page on this site before going on. That is how the number of clicks per retailer is counted — cookielessly, and with nothing that identifies you.

Nothing about you goes with you. Not your photo, which never left your device in the first place, and not your ring size or your hand's measurements. Where a retailer's search can be set from a link, the link carries the carat range and length-to-width ratio of the stone you chose, the depth and table percentages a well-cut stone of that shape usually has, and whether you asked for natural or lab-grown — so the search opens on stones like it. That is a description of a diamond, not of you. Otherwise the retailer sees only that someone arrived from this site, which every site on the web can see about its visitors. Which of these links earn this site a commission is set out in the disclosure notice.

What the site downloads

Beyond the page itself, two optional features fetch additional files — and both are served from this domain rather than a third party, so no outside company sees that you visited:

Both run entirely in your browser once loaded. If you never use those features, they are never downloaded. The only request the site makes to anything other than this domain is the Cloudflare Web Analytics beacon described above, and Cloudflare already hosts this site.

Sharing

Save or share this image creates the picture on your device and hands it to your operating system's share sheet — you choose where it goes, and nothing is sent automatically.

Copy a link to these stones produces a link containing only the stone measurements and ring size. Your photo is never included in a link and could not be; it stays on your device.

Hosting

The site is served by Cloudflare. Like any web host, Cloudflare processes basic connection information such as your IP address, browser type and the time of the request in order to deliver pages and protect against abuse. That is standard server logging and is separate from anything this application does.

Changes

If this policy changes materially — particularly if analytics or affiliate features are added — this page will be updated and the date above will change.
