Privacy Policy

Nothing. SchulteLab has no accounts, no analytics trackers, and no advertising SDKs. Your training results, personal bests and streaks are stored only in your browser’s localStorage on your own device. You can clear them anytime from the history panel or by clearing site data.

The site uses no tracking cookies. localStorage is used solely for your training history and interface preferences (theme, language).

Pages are served as static files. We do not embed third-party scripts that access your training data. If this ever changes, this policy will be updated before the change ships.

Questions about this policy can be sent to the contact address listed on the About page once the site domain is public.
