Information you choose to provide
You can browse and use the toolkit without creating an account. If you voluntarily submit the feedback form, the information you enter is sent to Tally so Chen Laoshi can read and respond to your message. Please do not submit student records, sensitive personal information, or information about a child.
Classroom Shop orders and payments
If you place a Classroom Shop order, you may choose to provide your name, quantity, mailing address, order question, and PayPal transaction number through the feedback form or by email. This information is used only to arrange and fulfill your order. Do not send payment-card details by email or through the feedback form. PayPal payments are processed on PayPal's website and are subject to PayPal's own privacy policy.
Information stored in your browser
Some classroom tools save word lists, game settings, or unfinished work in your browser's local storage. This information stays on your device unless you export it, clear your browser data, or use a feature that explicitly sends it elsewhere.
Advertising and cookies
Selected informational and directory pages use Google AdSense. Google and its partners may use cookies, web beacons, IP addresses, or similar technologies to deliver, measure, and protect advertising. Ad requests from this site are configured for Google's child age treatment as a conservative privacy choice. This disables personalized advertising and remarketing for those requests and applies additional ad-serving protections.

Third-party services and links
- Tally provides the optional feedback form.
- YouTube provides embedded videos on selected activity pages.
- PayPal and Amazon links open external services when you choose to use them.
- Google AdSense provides advertising on selected pages.
These services have their own privacy policies and may process information according to their terms.
Children's privacy
The website is designed for teachers and other adults and is not directed to children under 13. The site does not knowingly collect personal information from children. Because classroom resources may sometimes be displayed around students, advertising uses Google's more restrictive child age treatment as an extra precaution.
Your choices
You may block or clear cookies and local storage using your browser settings. Doing so may reset saved word lists or tool preferences. Visitors in regions where consent is required may also be shown Google's consent or privacy choices before eligible advertising is served.
Changes to this policy
This policy may be updated when the toolkit adds or changes services. The latest version and its update date will always be published on this page.
