Privacy policy
Short version: no accounts, no tracking cookies.
Last updated 12 November 2026.
Yuloy HSK has no accounts and sets no tracking cookies. Flashcard progress is stored in your own browser (localStorage) and never sent to us. Our host may process standard request logs to deliver and protect the site. When you tap a character for stroke order, your browser loads Hanzi Writer files from the jsDelivr CDN. Audio uses your device's speech engine. We may use privacy-focused, cookie-less analytics (such as Cloudflare Web Analytics) later; the token is currently unset, so no analytics script is loaded.
If you email us, we use your message only to reply and keep it no longer than needed.
