Privacy & Cookies

Last updated: 3 August 2026

Economicium keeps data collection to the minimum needed to run the site. This page explains what we collect, the cookies we and our partners use, and the choices you have.

Cookies & similar technologies

We use a small number of cookies and local storage:

  • Essential / functional, remembering your light/dark theme choice and the last inputs you type into a tool, so a calculator opens the way you left it. These stay in your browser and don't track you across other sites.
  • Security, if bot-protection is enabled on forms, our provider (Cloudflare Turnstile) may set a cookie to tell humans from bots.
  • Analytics, set by Google Analytics and Microsoft Clarity to understand how visitors use the site (pages viewed, approximate location, device) so we can improve it. Only set with your consent where required.
  • Advertising, set by Google and its partners to show and measure ads (see below). These are only used with your consent where required.

Advertising (Google AdSense)

We show ads through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to Economicium and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to our site and/or other sites on the internet.

You can control personalised advertising:

We ask for your consent before non-essential (advertising and analytics) cookies are set, via a consent banner shown on your first visit. You can change your choice at any time from the "Cookie settings" link in the footer of any page.

Analytics (Google Analytics & Microsoft Clarity)

We use Google Analytics 4 and Microsoft Clarity to understand how the site is used, which pages are popular, where visitors come from, and where the experience can be improved. These tools set cookies and collect usage data such as pages viewed, approximate location, and device and browser type. Microsoft Clarity also builds aggregated heatmaps and session replays; text you type is masked by default, and we do not use any of this to identify you.

See Google's privacy policy and Microsoft's privacy statement. You can opt out of Google Analytics with the opt-out browser add-on.

Your inputs stay in your browser

The calculators, the trading journal and the statement analyzer run entirely on your device. Your account balance, risk settings, trades and any file you drop in are processed in your browser and, unless you turn on trading-journal sync (below), never sent to us or stored on our servers. Where a tool remembers your last inputs, it uses your browser's local storage, which you can clear at any time.

Trading-journal sync (optional)

The trading journal is local-first: by default your trades live only in your browser. If you choose to sign in with Google, we store a copy of your journal so it syncs across your devices. What we store is limited to your trade entries, keyed to the stable account identifier Google returns when you sign in. We never receive or store your Google password, and we do not use your email address as the key or for marketing. Signing in relies on Google Identity Services; see Google's privacy policy. You can remove the synced copy at any time with the journal's "Remove cloud copy" button, or by emailing us; signing out leaves the local copy on your device untouched. Stay signed out and nothing from the journal is ever uploaded.

Contact form

If you message us, we use the name, email, and message you provide solely to reply. We don't use it for marketing.

Data retention

Contact messages are kept only as long as needed to handle your enquiry. Anything a tool saves (your theme and your last inputs) lives in your browser's local storage, not on our servers, so clearing your browser data removes it.

Your rights & contact

You can request access to or deletion of your data, or ask any privacy question, at our contact page. If we change this policy, we'll update the date above.
