PRIVACY
A simple guide.
A clear policy.
Last updated September 20, 2026.
On this website
This site uses Google Analytics 4 (measurement ID G-FPWPW9B9RM) to measure page views and referral-link clicks. Google Analytics may use cookies and process device, browser and usage information. Learn more at Google’s privacy policy. This site has no membership or payment forms. The membership calculator runs in your browser and does not send your selections to us. The calculator itself does not use cookies or local storage.
Hosting records
The hosting provider may process standard request information such as IP address, browser information and requested pages to deliver and secure the website. Retention depends on the provider’s configuration.
Referral links and other websites
Referral links include a referral identifier and lead to Zoom Tan’s membership store. That website may use its own tracking, cookies and account information under its privacy policy. Purchases and membership details are handled there, not on this guide.
Policy changes
This policy should be updated if forms, analytics or other data collection are added. Do not submit payment or membership details to this independent guide.
