Privacy Policy

Who Is Responsible For Personal Information

Personal information collected through this site is handled by Boyu Technology (Shanghai) Co., Ltd. Privacy and personal-information requests can be sent to info [at] mandarinhanhe.com. The company identity in this section is provided only to explain who is responsible for the processing.

What We Collect

When you contact us, request course matching, submit a review or correction, apply to list a school or independent teacher, or make a school enquiry, we receive the name, email, optional contact details, enquirer role, school or teacher preference, course and start-date preferences, visa-support preference, school history or teacher profile, message content, and necessary abuse-prevention results and security logs that you submit. We do not ask for identity-document numbers, payment information, or sensitive identity details about children in these forms.

Purposes And Confirmation Flow

We use this information only to respond, verify email ownership, route a confirmed submission to the site administrator, prevent spam, maintain directory quality, and meet security duties. Every public form is first stored privately. We email the address supplied, and the submission enters the administrator notification queue only after the sender actively confirms on the confirmation page. Unconfirmed content is not forwarded to a listed school or teacher and does not enter public moderation.

Consent And Withdrawal

Before submitting any public form, you must agree to this policy, including the abuse-prevention and email-confirmation processing described below. You may choose not to use the confirmation link, or contact us to withdraw consent or request deletion. Withdrawal does not affect processing lawfully completed before it.

How Directory Information Is Collected

The “Mandarin Schools and Courses by City” directory uses public web sources: official school sites, course pages, public directories, third-party review platforms, travel/study-abroad sites, blogs, forums, and experience articles. We keep source names, links, collection dates, and visible published or updated dates when available.

Inclusion Method

Before a provider is public, we check for an official or credible public page, clear city/campus information, visible course details, recent update signals, visa notes when available, and independent public sources. Weak new leads remain in a local observation queue.

Reviews And Sources

Third-party review context is shown with source names and links. We prefer short excerpts or short summaries. Provider-owned testimonials are labeled separately and are not treated as independent third-party reviews. Ordinary negative experience can remain; profanity or clear abuse may be masked or removed.

Cookies And Security

The site may use basic cookies or technical logs for language preference, abuse prevention, caching, and security. School enquiries preferentially use Cloudflare Turnstile to assess whether a submission comes from a person; Cloudflare may receive the network, device, and interaction signals needed for that check. If it is unavailable on the visitor's network, the site uses its own signed arithmetic fallback and sends no data to another verification provider. Confirmation and administrator notices are sent through our same-domain mailbox and its email provider. These services may process necessary technical or mail-transport data outside your location. We minimize fields and retention, do not sell personal information, and do not use enquiries for bulk marketing.

Retention

New form records that remain unconfirmed are normally deleted from the site after 7 days. Confirmed records are normally kept for no more than 180 days so that the request and response can be handled. Approved public school or teacher information is managed separately from private contact records and remains until it is withdrawn, replaced, or becomes obsolete. A narrowly necessary extension may apply to an active conversation, dispute, or legal duty. Security logs, mail-system records, and backups follow their shortest necessary security and recovery cycles, after which they are deleted or de-identified.

Children

If an enquiry concerns a learner under 14, a parent or other guardian should submit it and agree to this policy. Do not enter a child's identity-document number, precise home address, or other sensitive information in free text. If unnecessary sensitive information about a child is found, we will restrict its use and remove it promptly.

Your Rights

You may ask to access, copy, correct, supplement, or delete personal information, withdraw consent, or ask about these processing rules. To prevent impersonation, we may first verify the requester's relationship to the relevant email address. Contact info [at] mandarinhanhe.com.

Corrections And Removal

If you represent a listed provider, authored a review, or are connected to listed information, contact info [at] mandarinhanhe.com to request correction, source updates, or removal of inaccurate content.
