Website measurement

We count page views and Google Play link clicks on the home and learning pages. Each event contains the page path, language, event type, button location when relevant, a broad referral category, and the time received. These measurement events do not include your name, email address, account ID, IP address, full referring URL, or URL query parameters. We do not set measurement cookies or store an identifier in your browser. We also classify recognized AI referral hosts as ChatGPT, Perplexity, Copilot, Gemini, or Claude. We do not store the referring URL or conversation. Missing referrers cannot be attributed to an AI provider.

These counts are events, not unique people, verified installs, or completed lessons. Browser privacy controls and blocked requests can reduce the counts. The site respects Do Not Track and Global Privacy Control for these events. Server and network access logs are separate and may contain connection information.

Google Play links include campaign labels identifying this website, language, page, and button. Google processes store visits under its own policies. We do not send page-view or click events from legal or account-deletion pages.
