Privacy Policy

1. The short version

This site sets no advertising cookies, runs no analytics scripts, loads no third-party resources, and does not build a profile of you. It stores one thing in your browser: the contents of your shopping cart, in local storage, on your own device. It never leaves your machine unless you place an order.

2. What we collect, and when

Before you order, we collect nothing about you. There is no account, no login, no tracking pixel.

When you place an order, we receive and store:

• The email address you provide, so the download link and receipt can be delivered.
• The optional name or company you type, if you want it on the invoice.
• The optional note you type, if you have a question about the order.
• The products and quantities in the order, and the amount paid.
• An order reference and the date of the transaction.

We do not receive your card number, card expiry, billing address or bank details. Those are handled entirely by the payment platform, which is the merchant of record. We receive only the confirmation that the payment succeeded and the amount.

3. What the payment platform collects

The checkout is processed by a third-party digital commerce platform. When you pay, you are interacting with that platform's own checkout page and that platform's own privacy policy applies to the payment data it collects. That typically includes your email, card details, country, and the tax calculation for your jurisdiction. We do not control that collection and cannot see its contents.

If you choose the email order route instead, no payment data is collected by anyone at that moment. We receive your email and the order contents, and we reply with a payment request.

4. Why we hold it, and for how long

• Delivery. The email address is needed to send the download link and the receipt.
• Support. If you write to us later, the order history lets us find your purchase without asking you to prove it.
• Accounting. Transaction records are kept as required by the tax and accounting rules that apply to the store operator. That is typically a multi-year retention obligation, not a choice.
• Refunds. The 14-day refund window requires us to be able to identify the order.

Order records are kept for as long as the accounting obligation requires. Marketing is never sent: there is no mailing list, no newsletter, and no promotional email. The only email you will receive from us is about an order you placed, or a reply to a message you sent.

5. Who else sees it

Data is shared only with parties needed to complete the order:

• The payment platform that processes the transaction and issues the receipt.
• The email provider that delivers the receipt and download link.
• The hosting provider that serves this website.
• An accountant or tax authority, where the law requires disclosure of transaction records.

We do not sell, rent, trade or share personal data with advertisers, data brokers, or any party for marketing purposes. There is no advertising relationship to disclose because there is no advertising.

6. Cookies and local storage

This site sets no cookies. It uses browser local storage for exactly one purpose: keeping your cart between page loads. That data is stored on your device, is readable only by this site, and can be cleared by clearing your browser's site data. It is never transmitted to us until you place an order.

The payment platform's checkout page may set its own cookies when you reach it. Those are governed by that platform's policy, not this one.

7. Your rights

Depending on where you live, you may have the right to:

• Ask what personal data we hold about you.
• Ask for a copy of it in a portable format.
• Ask us to correct data that is wrong.
• Ask us to delete data, where no legal retention obligation applies.
• Object to a particular use, or ask us to restrict it.

To exercise any of these, email 1761603898@qq.com from the address you ordered with, or include your order reference. We reply within 30 days. There is no fee. If a request conflicts with a retention obligation, we will tell you which record must be kept and why, and delete everything else.

8. Security

The site is served over HTTPS. Order records are held in the payment platform and in a mail account, both access-controlled. We do not run a database of customer records on a server we administer. No system is perfectly secure, and we make no absolute guarantee, but the amount of data at risk here is deliberately small: an email address, an order reference and an amount.

9. Children

The store sells developer tools and is not directed at children. We do not knowingly collect data from anyone under 16. If you believe a minor has placed an order, email 1761603898@qq.com and we will cancel and refund it.

10. International transfers

The store operator is established in mainland China. Order data is processed by the payment platform and email provider, which may process it in other jurisdictions under their own safeguards. By ordering, you understand that your order data may be processed outside your country of residence.

11. Changes

If this policy changes materially, the date at the top changes and the previous version stops applying to new orders. Changes never widen the use of data already collected under an earlier version without your consent.

12. Contact

Privacy questions and data requests: 1761603898@qq.com. Everything else: the contact page.
