Last updated: October 2026. Short version: we don't collect personal information from you, and we use standard advertising cookies.
Mahjong Card Guide is a static information site. We do not collect, store, or process any personal information about you directly — there is no account system, no newsletter, and no login. The hand checker tool runs entirely in your browser; nothing you enter is sent to us.
We use Google AdSense to display advertisements. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to this and other websites.
Some pages may link to third-party websites (including retailers for products we discuss). We are not responsible for the privacy practices of those sites. Our affiliate relationships are disclosed where applicable.
Our content is intended for adults. We do not knowingly collect any information from children under 13. Our site does not use features designed to attract children, and we comply with the Children's Online Privacy Protection Act (COPPA).
We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
