Privacy

This is a static website with no account system, no comment system, no fingerprinting and no session replay. It uses the third-party analytics and chart services described below; one of them, Google Analytics, sets cookies.

Session notice.A short-lived marker records that the opening notice has already been shown, so it appears once per browsing session rather than in every tab or on every page. It is stored in a session cookie holding only the value "1", with a copy in your browser's session storage. It contains nothing about you, identifies nothing, and disappears when you close the browser.

Analytics (Cloudflare Web Analytics).Pages load Cloudflare's Web Analytics beacon to measure aggregate traffic: page views, referrers, and load performance. It is cookieless: it sets no cookies, stores nothing on your device, and does not track you across sites or build individual profiles. Measurement is based on the page visit itself, not on you. See Cloudflare Web Analytics and Cloudflare's privacy policy.

Analytics (Google Analytics). Pages also load Google Analytics 4 (gtag.js, measurement ID G-FD807GKS5B), operated by Google. Unlike the Cloudflare beacon, it sets cookies and uses identifiers to measure traffic and engagement: pages viewed, approximate location derived from your IP address, and device and browser information. It loads when you visit a page. Google processes this data as described in Google's privacy policy and how Google uses information from sites that use its services.

Price charts and quotes (TradingView). Pages embed the free TradingView widgets solely to display price history, and the home page additionally shows a watchlist quote strip. Your browser connects directly to TradingView to load them. According to TradingView's widget documentation. The widgets do not set cookies; TradingView receives the URL of the embedding page, the widget type and displayed symbol, and your IP address, used to operate the widget and protect its servers. See TradingView's privacy policy. The charts and quotes are display-only market context: no TradingView data is collected by this site or incorporated into Signal21 forecasts.

Newsletter. The newsletter collects exactly one thing: the email address you submit, used solely to send the outlook you subscribed to. Subscription completes only after you confirm it from your inbox (double opt-in): an unconfirmed address is never subscribed. Data controller: Signal21 XYZ (contact below). Processor: the address is stored and confirmation emails are sent by Brevo (Sendinblue GmbH, Germany), our newsletter provider, under its data-processing agreement. Every email contains an unsubscribe link, and you can request deletion at any time via contact@signal21.xyz.
