Information you choose to provide
You can browse and use the toolkit without creating an account; teacher accounts are optional and described below. 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.
Optional teacher accounts and cloud saving
Every tool works without an account. If you choose to create a teacher account, sign-up and sign-in are handled by Microsoft Entra External ID, a Microsoft service. You create your password on Microsoft’s sign-in page; this site never receives or stores it.
- From Microsoft, the site receives your name, email address, and a unique account identifier when you sign in. The site’s database keeps your email address and name with your account so Chen Laoshi can find your membership when you ask for help or pay for a membership. The site never receives or stores your password.
- The site’s database stores your email address, your name, when you signed up and last signed in, a one-way coded version of your account identifier, the materials you choose to save to the cloud (such as word lists and question banks), a list of the games, quizzes, and books you shared while signed in (name, type, and date, so you can find them on any device), and your membership details: when a free trial started, when cloud saving ends, which activation codes were used, and a dated history of each change to your membership (trial, activation codes, and refunds). Activation codes are stored only in coded form.
- This information is used only to sign you in, show your name, keep your saved materials available across devices, manage your trial or membership, and answer your support or payment questions. It is not sold, shared for advertising, or used to personalize ads.
- Sign-in data is held by Microsoft in the United States. Your saved materials and membership details are stored in Microsoft Azure in Canada.
- If you buy a membership, payment is processed by PayPal under PayPal’s own privacy policy; the site does not receive your card details. PayPal shares your name, email, and payment note with Chen Laoshi, which are used only to confirm your payment, deliver your activation code, and handle refunds.
Please do not put student names or other personal information about students into saved materials. When cloud saving ends, your materials stay readable and downloadable. To delete your account and everything stored with it, email clsteachingtools@gmail.com from the address you signed up with; your saved materials, account record (including your email address), membership record, and sign-in account will be deleted within 30 days.
Shared games and student quiz results
When a teacher creates a shareable game link, the game content is stored on the site so students can open it. For one-time quizzes, each student types a name and their answers and score are saved so the teacher can review results. Shared links stay open for 7 days, or 180 days when made by a member, and can then no longer be opened, and the teacher who created a link can delete it at any time. Teachers should ask students to use a first name, nickname, initials, or student number rather than a full name.
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.
- Microsoft Entra External ID provides optional teacher sign-in, and Microsoft Azure hosts the website, its database, and shared game links.
- Microsoft Clarity collects anonymous usage information, such as clicks and scrolling, to help improve the site.
These services have their own privacy policies and may process information according to their terms.
Affiliate recommendations
The Classroom Recommendations page contains Amazon affiliate links. If you follow one of these links and make a qualifying purchase, the site may receive a small commission without increasing your price. Affiliate links are marked with a disclosure and do not affect the educational guidance on this site. Amazon may use cookies or similar technologies under its own privacy policy when you visit its service.
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. Names that students type into a teacher’s shared quiz are handled as described in “Shared games and student quiz results” above. 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. If you sign in to a teacher account, the site uses essential sign-in cookies to keep you signed in; they are removed when you sign out.
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.
