Privacy Policy

Last updated: 6 September 2026 · Operator: Deng Daqiang · Support: dengdaqiang@163.com

What FeeMath is

FeeMath is an independent Etsy fee and profit calculator. It is not affiliated with Etsy, Inc.

Calculator data (not sent to us)

Order prices, costs, fees, and profit figures you type into the free calculator are processed only in your browser. We do not upload, store, or sell those numbers. FeeMath Pro is designed the same way: Etsy CSV files are parsed locally in your browser.

What we do collect

• Waitlist email. If you submit the waitlist form, we store your email address, an optional referrer, a timestamp, and basic request metadata (IP and user agent) so we can email you when Pro launches and to limit abuse.
• Support email. If you write to dengdaqiang@163.com, we keep the correspondence as needed to reply.
• Payments. Paid subscriptions are processed by Creem, who acts as merchant of record. Card and tax data are handled by Creem under their privacy notice, not stored on FeeMath servers.

Cookies and tracking

The site does not use advertising cookies or third-party analytics pixels. Your browser may still send standard technical request logs to the host (for example IP address and user agent) as part of serving the page.

How long we keep waitlist emails

We keep waitlist addresses until Pro has launched and we have emailed you, or until you ask us to delete them. Email dengdaqiang@163.com to be removed.

Legal bases and your rights

If you are in the EEA/UK, we process waitlist emails to take steps at your request (joining a product waitlist) and to contact you about that product. You may request access, correction, or deletion of the email we hold by writing to the support address above.

Children

FeeMath is intended for adult shop operators. We do not knowingly collect data from children.

Changes

We may update this policy. The date at the top will change when we do.
