What we hold when you ask about a racket.

HEFEI DAISAI TRADING CO., LTD. (合肥戴筛商贸有限公司) is the personal information processor for this site. Our registered office is in Hefei, Anhui, China; write to the mailbox below for the full registered address, the unified social credit code and the name of the legal representative. The mailbox for every privacy request is JINGHE1910@outlook.com. This notice covers kennove.com only; it does not cover any site we link to.

When you email or message us we receive whatever you choose to send: name, email address, phone number, delivery address, the product or SKU you asked about, quantity, and the notes that make a racket quote possible. Those notes usually include string tension in lbs, string gauge, grip size, balance preference, frame stiffness if you know it, junior player height and age, and your court surface. We keep them because they are the quote.

Our servers also write standard logs: IP address, browser and device type, the pages requested, timestamps and error codes. Logs are for security and uptime, not for profiling. We do not run advertising pixels, we do not embed social plugins, and we do not load fonts or scripts from third-party CDNs on this site.

If we string a frame for you, or if you claim a fault, we record the set-up with the order: tension in lbs, gauge and string model, knot type, grip size and any build-up layers, the date of the string job, and the frame model and serial if the supplier provides one. Order correspondence, photographs of a cracked frame and courier paperwork are filed with the same record.

This matters because a warranty claim about a frame that failed at 26 lbs after eight months cannot be judged without knowing what was strung and when. The record is kept with the order so we can compare a second string job against the first, and so a claim is decided on evidence rather than memory.

This site sets no advertising or analytics cookies. A session cookie may be used to keep a short-lived cart selection and a form state between page loads; it expires when you close the browser. If you block cookies entirely the pages still work, because nothing here depends on tracking you. There is no consent wall to click through and no dark pattern hiding a reject button. When the PayPal checkout opens, PayPal sets its own cookies on its own domain under its own privacy notice; this site sets none for payment.

We use enquiry data to answer you, to quote a frame set-up, to arrange shipping, to handle a return or a warranty claim, and to keep the accounting records PRC law expects. Under the PIPL the grounds are straightforward: your consent when you write to us, the necessity of processing to conclude or perform the contract when you accept a quote, our legal duty for tax and accounting records, and the necessity of processing to keep the site secure and the desk accountable.

PayPal processes card and PayPal payments and receives your name, email address, delivery address and the order total. It does not receive your enquiry notes or stringing records. Our mailbox provider carries email. A courier receives the delivery name, address and phone number, and nothing else. Our bank and, where a payment is made by transfer, the receiving institution see the invoice reference and amount. A stringer receives the frame and the tension sheet if the work is done outside our own bench. We do not sell, rent or trade personal data, and we do not pass a customer list to anyone for marketing.

This site and our mailbox run on servers outside mainland China, and some service providers store data outside mainland China. We keep any cross-border transfer to the minimum needed to run the service. Where the PIPL applies to a transfer, we rely on the mechanism the law provides — a security assessment, a certification, or a standard contract filed with the regulator — and we ask for your separate consent where the law requires it. Email is the main channel; if you need your racket notes kept inside mainland China, tell us before you send them and we will say what we can arrange locally.

Enquiries that never became an order are deleted after 24 months. Invoices and payment records are kept for ten years because PRC tax and accounting rules require it. Server logs roll off after 90 days unless a security incident needs them longer, and then only that incident's logs are held.

You may ask what we hold about you, ask for a copy, ask us to correct anything wrong, ask us to delete what we are not required to keep, ask for your data in a portable format, ask us to explain how we process it, or withdraw consent you gave earlier. You may withdraw consent for future marketing at any time, though we do not run marketing lists in the first place. Write to JINGHE1910@outlook.com and we will confirm within one working day and complete the request within 15 working days. We may ask you to prove you are the person in the record before we release anything.

Tell us first; most issues are a misfiled email. If we cannot settle it, you may complain to the cyberspace administration or the market supervision authority at the place where we are registered, or bring a claim before the competent people's court in Hefei. Nothing in this notice limits a right you have under the PIPL.

We quote junior frames regularly, and a parent or coach normally writes on the child's behalf. We do not knowingly collect personal data from a child under 14 without the consent of a parent or guardian, and we do not need a child's email address to size a 25 inch frame. If you believe a child has sent us personal data, write to us and we will delete it.

If this notice changes we republish it on this page and move the date at the foot. Material changes are announced to anyone with an open order. Questions go to JINGHE1910@outlook.com, or by post to our registered office in Hefei, Anhui, China.
