Privacy Policy

Never uploaded. SchulteLab has no accounts. Your training results, personal bests and streaks are stored only in your browser’s localStorage on your own device — they are never sent to our servers or any third party. You can clear them anytime from the history panel or by clearing site data.

We use Google Analytics 4 (gtag.js) to understand aggregate site usage: which pages are visited, approximate region, and device type. GA4 does not log or store your IP address, and it never receives your training data — scores and history never leave your device. It sets a first-party cookie (_ga) only to distinguish visits. You can opt out with Google’s browser add-on (tools.google.com/dlpage/gaoptout) or by blocking cookies in your browser settings. Google Analytics Opt-out Add-on

localStorage is used for your training history and interface preferences (theme, language). The only analytics cookie is Google Analytics’ _ga cookie described above. We use no advertising cookies.

Pages are served as static files. The only third-party script loaded is Google Analytics (gtag.js, served from googletagmanager.com). We embed no advertising SDKs, and no third party can access your training data.
