Privacy Policy
What we collect, what we do not, and what the payment processor sees.
Last updated: 29 October 2026.
The short version
LeeChuanjing Shop does not ask you to create an account. We do not collect names, email addresses or payment details on our own servers. Payment is processed entirely by Gumroad, and our own servers receive no payment data at all.
What we collect
Our hosting provider (Cloudflare) keeps standard server logs — IP address, browser type, requested URL and timestamp — for security and abuse prevention. These logs are retained for a short period and are not used to build a profile of you.
If you contact us by email, we keep your message and address so we can reply. We do not add it to a marketing list.
Cookies
Our own pages set no tracking cookies and use no analytics. If advertising is displayed on this site in future, the ad provider may set cookies under their own policies, and a consent notice will appear before they do. The free calculators and the shop pages work fully without cookies.
Payment
All payments are handled by Gumroad. Your card details go directly to them and never touch our servers. Gumroad's own privacy policy governs that processing. We receive only what we need to deliver your order and to answer support requests: typically an order identifier, the product name and your email address, so that we can resend a download link if something goes wrong.
Third-party links
Product pages link to Gumroad for checkout. When you follow those links you leave this site and Gumroad's terms and privacy policy apply. We do not control how third-party sites handle data.
Your rights
If you are in the EU, UK, California or another jurisdiction with data protection rights, you can ask us what we hold about you, ask for it to be corrected, or ask for it to be deleted. We will respond within 30 days. Email us through the contact form.
Children
This site is not directed at children and we do not knowingly collect data from them.
Changes
If this policy changes materially we will update the date at the top of this page and, where the change is significant, note it on the site.
