# Cookie Policy

Version 1.9, 9 November 2026

This cookie policy lists every cookie and similar technology used on **digitalgemology.com**, who sets it, what it does and how long it lasts. It supplements our [Privacy Policy](https://digitalgemology.com/privacy). The site is operated by Compliance Condo B.V., trading as Digital Gemology, Koningin Wilhelminaweg 219, 2802 HE Gouda, the Netherlands (KvK 95458859).

**Analytics only if you say yes. No advertising.** We use Google Analytics to count visits, but it loads only after you click *Accept* in our cookie banner, and *Reject* is just as easy. Everything else listed below is either necessary to run the site, or a preference you set yourself.

## 1. What cookies are

Cookies are small text files that a website stores on your device. We also use *localStorage*, a comparable browser technology that keeps a small piece of information on your device without sending it to a server. Both are covered by this policy, by the Dutch Telecommunications Act and by the GDPR.

## 2. What we use

### 2.1 Necessary: always active

| Name | Set by | Purpose | Storage period |
| --- | --- | --- | --- |
| `dg-theme` *(localStorage)* | Digital Gemology (first party) | Remembers your choice of page theme, black (the default) or white. Set only if you use the switch in the menu. Stored on your device only and never sent to us. | Until you clear it |
| `dg-consent` *(localStorage)* | Digital Gemology (first party) | Remembers whether you accepted or rejected analytics, so the banner does not ask again on every page. Stored on your device only and never sent to us. | 12 months, then we ask again |
| `dg-cuts-view2` *(localStorage)* | Digital Gemology (first party) | Remembers which picture the cards on the [cuts overview](https://digitalgemology.com/cuts/) show: 3D, light map or facet mesh. Set when you open that page. Stored on your device only and never sent to us. | Until you clear it |
| `dg-own-stone` *(sessionStorage)* | Digital Gemology (first party) | Keeps the shape of a stone file you open yourself in the simulator or another tool, so the other tools can show the same stone. Set only if you open your own file. Stored on your device only; the file is never uploaded or sent to us. | Until you close the tab |
| `dg-studio` *(localStorage)* | Digital Gemology (first party) | Remembers your [Studio](https://digitalgemology.com/studio) settings for pictures and videos: format, size, quality, length and labels. Set only if you change one. Stored on your device only and never sent to us. | Until you clear it |
| `__Host-dg_session` | Digital Gemology (first party) | Keeps you signed in after you sign in with Google: your name, email address and Google account ID, signed so that they cannot be altered. Set only when you sign in; signing out deletes it. We keep no copy on our servers. | 30 days |
| `__Host-dg_oauth` | Digital Gemology (first party) | Protects a sign-in against forgery while you are on Google's sign-in screen. Set when you click *Sign in with Google* and deleted when you come back. | Up to 10 minutes |
| `__cf_bm`, `cf_clearance` | Cloudflare | May be set by our hosting provider to tell people from bots, so the site stays available and is not scraped or attacked. Not used for advertising and does not follow you across other websites. | Up to 30 minutes (`__cf_bm`); up to 1 year (`cf_clearance`) |

**Checkout.** When you click *Buy*, checkout opens on Lemon Squeezy's own site, digitalgemology.lemonsqueezy.com. Cookies set there, including those of its payment processors for fraud prevention, belong to Lemon Squeezy and fall under its own cookie and privacy policies. Nothing from checkout is set on digitalgemology.com.

The [3D Gemstone Simulator](https://digitalgemology.com/tools/3d_gemstone_simulator) sets no cookies. The settings you choose are kept only in the page address. If you open your own stone file, it uses `dg-own-stone` above.

### 2.2 Analytics: only with your consent

If you click *Accept* in the cookie banner, we load Google Analytics to count visits, see which pages and tools are used, and count clicks on the buy buttons, the free sample and the links from a tool to a cut (the events `begin_checkout`, `generate_lead` and `tool_to_product`, with the product and price but nothing about you; [privacy policy, section 2.5](https://digitalgemology.com/privacy)). Until you do, nothing is loaded from Google and nothing is sent to it. If you click *Reject*, or ignore the banner, it stays that way.

| Name | Set by | Purpose | Storage period |
| --- | --- | --- | --- |
| `_ga` | Google Analytics (Google Ireland Limited) | Tells one visit from another by a random number, so we can count visitors rather than page loads. | 2 years |
| `_ga_LL6PQMFLX4` | Google Analytics (Google Ireland Limited) | Keeps track of the current visit (session) for the same count. | 2 years |

With these cookies, Google receives the pages you view, the site that sent you, and your browser, device type and approximate location. Google Analytics does not store IP addresses. We see only totals: the reports never tell us who you are. Advertising features are off: the tag runs with advertising storage and ad personalization refused. Google may process the data in the United States; see our [Privacy Policy](https://digitalgemology.com/privacy) for the safeguards.

We use no advertising pixels or other trackers.

### 2.3 Trustpilot: a plain link

The *Review us on Trustpilot* button at the bottom of every page is a plain link to our profile on trustpilot.com. Nothing loads from Trustpilot and nothing is sent to it until you click the button. Once you click through to trustpilot.com, Trustpilot's own cookie policy applies.

### 2.4 YouTube videos on our lesson pages

The lesson pages under [/learn](https://digitalgemology.com/learn) show each video as a still picture from our own server. Nothing loads from YouTube until you press play. Then the player loads from YouTube in privacy-enhanced mode (youtube-nocookie.com), and YouTube's own terms and privacy policy apply.

## 3. Managing cookies

- You can change or withdraw your analytics choice at any time with *Cookie settings* at the bottom of every page, or with the button in section 2.2. When you withdraw, we remove the Google Analytics cookies and stop loading it.
- You can delete or block cookies and clear localStorage through your browser settings.
- Blocking Cloudflare's cookies may mean you are asked to prove you are not a bot. Clearing `dg-theme` simply returns the site to its default black theme. Deleting `__Host-dg_session` signs you out.

## 4. Changes to this policy

We update this policy when the site, our providers or the law change, and always before a new cookie is used. The version and date are stated at the top of the page.
