Privacy notice

Two third parties here: Google Analytics 4 for the visitor count, and Cloudflare in front of the server. This page sets out what each one sees, and how to switch the analytics off.

Analytics and cookies

This site runs Google Analytics 4 (GA4) to measure page views and where visitors come from. When you open a page, the page URL, the referring URL and technical details about your browser and device go to Google; as with any network request, your IP address reaches Google along with it. GA4 may also write first-party analytics cookies in your browser (_ga and one starting with _ga_), which according to Google are used to tell visitors apart and to tell one visit from another. We do not send names, email addresses or exchange account details, and we do not send anything you type into the tools — the tools still do all their arithmetic locally in your browser.

If you would rather not be counted, there are two ways out: install Google's own Google Analytics Opt-out Browser Add-on, or block the analytics script with a content blocker. Either way the pages and the tools keep working. Restricting or clearing cookies on its own is not enough: Google states that the GA4 code can send data without setting cookies, so without them it simply cannot tell that two visits came from the same visitor. For what Google does with the data on its side, see the Google Privacy Policy.

What this site does not do

No advertising. No ad network, and therefore no advertiser tracking pixels.
No accounts. You cannot register or log in, so there is no user data to collect.
No email marketing. No subscription form, no address collection. If you want to follow updates, use RSS — that is completely anonymous.

Data in the tools

Every tool on this site runs in your browser. The trade volumes, entry prices and addresses you type are not sent to any server and are not stored — close or refresh the page and they are gone.

You can verify this yourself: disconnect from the network and the tools still calculate normally.

Third-party resources: Google and Cloudflare

Open any page here and your browser makes requests to this site's own wickvo.com, to Google's www.googletagmanager.com (the GA4 script), to *.google-analytics.com or *.analytics.google.com (where GA4 reports back), and to static.cloudflareinsights.com. According to Google's technical documentation, if Google signals is switched on in the GA account, addresses under *.g.doubleclick.net and google.com can appear as well; that is an account setting and cannot be seen in the page code. Nothing else — the stylesheet, the script, the images and the Latin display typeface are all hosted here. No CDN, no external font service, no embedded video or map.

The Cloudflare one is a traffic-counting script. That line is not in this site's page files; Cloudflare adds it on the way out. Cloudflare is the network this site sits behind, the script is a switch in its dashboard, and we have chosen to leave it on.

What it counts: how many times a page was opened, roughly which country the visitor was in, which browser, and how fast the page loaded. By Cloudflare's own account it sets no cookie and does not follow you across sites. What reaches our dashboard is totals — no individual is identifiable in it and we see no IP address for any single visit. How that layer actually behaves is Cloudflare's account of itself, and we have no way to verify it independently. Treat that as a general caution: when any site tells you a third party is not tracking you, that is usually as far as its knowledge goes too.

You can check that list yourself: open your browser's developer tools, switch to the network panel and reload. The requests should go only to the Google and Cloudflare addresses described above. If a different one appears, either we have got this wrong or something else has happened — please tell us through the contact page.

This was not always true The display typeface used to be loaded from Google Fonts, which meant every visitor's browser made a request to Google's servers carrying their IP address and browser details. Since 2026-08-25 the font has been self-hosted and that request no longer exists. The change is recorded in the Chinese corrections log, where it was originally logged.

What the server side leaves behind

Server access logs

Like every website, the server that hosts this one produces technical logs while handling requests — typically IP address, timestamp, requested page and browser identifier. That is an inherent part of running a network service. It is used only to keep the site available and to diagnose faults; we do not profile visitors with it and do not share it with any third party.

External links

Once you click a link to an exchange, block explorer or other external site, you are under that site's privacy policy. We have no control over how they handle data, and you should read their policies yourself.

Your rights

This site has no accounts and stores nothing you submit, so we hold no file on you to look up, correct or delete. The GA4 data is held by Google; what reaches our dashboard is aggregate reporting in which no individual is identifiable. For access, rectification, erasure or portability on Google's side, use the routes set out in the Google Privacy Policy. The most direct option is to stop the data being generated at all, using either of the two methods above.

If you have a question about this page, or think we have missed something, raise it through the contact page.

Changes to this page

If any of the above changes again — a different analytics tool, another third-party service, or the analytics coming back out — we will update this page and leave an entry in the corrections log rather than editing it silently. Switching GA4 on, on 2026-10-07, is logged exactly that way.
