Privacy Policy
Last updated: October 20, 2026
Browsing this website
SenMandarin is an educational website operated by Jason (杨森). This version does not provide user accounts, collect form submissions, process payments, or maintain a student database. We have not added advertising, third-party analytics, tracking pixels or marketing cookies.
Search and local interactions
Search runs in your browser using a static index served with the website. Library filters are reflected in the URL. The copy button writes the displayed WeChat ID to your clipboard only when you press it. The site does not read your clipboard.
Contacting Jason
If you choose to contact Jason through WeChat or email, the information you send is handled in that service. Share only the information needed to discuss lessons. WeChat and your email provider have their own privacy terms. Selecting an email link opens your email application; this website does not send or store your message. A message is not a confirmed booking.
Hosting
Cloudflare, our hosting provider, may process technical request information, such as IP addresses and request timestamps, to deliver and secure the site. Cloudflare Pages delivers this website. This website does not independently store those logs in a database.
Your questions
For questions about information you have shared directly with Jason, contact him through the WeChat details on the lesson page. Email: y996270903@163.com.
Changes
If new services or data collection features are added, this policy should be updated before those features are enabled.
