Privacy Policy

Effective date: November 2026 · Version 1.0

01 Who we are and what this policy covers

This site, hl-filters.com, is operated by Shandong Huali Electromechanical Co., Ltd., Jining, Shandong Province, China.

For the information described in this policy, we are the controller. That means we decide why the information is collected and how it is used. You can reach us about it at [email protected], or through any channel on our contact page.

We supply engine-service filtration for Cummins- and Perkins-powered equipment. Cummins and Perkins are named as engine applications and original reference names only. They are not our brand, and this site does not claim any authorised or original-equipment relationship with either company.

What this policy covers

This policy covers personal information collected through hl-filters.com and through the channels published on it: the quotation form, the contact form, email, WhatsApp and telephone.

It does not cover:

  • Pages we link to. If you follow a link to another website, including WhatsApp, that site’s own policy applies.
  • Information you send us by other means, such as a message to a sales representative’s personal account, unless it reaches one of the channels above.

You do not need an account to use this site, and we do not create one for you. This is a business-to-business site for engine service. It is not directed at children, and we do not knowingly collect their information. If you believe a child has sent us information, write to us and we will delete it.

02 What we collect and how we receive it

We receive two kinds of information: what you type or upload, and what the site records when you visit.

Where it comes from What we receive Why
Quotation form Name, company, email address, phone or WhatsApp number, country, engine model or serial number, part number, filter type, quantity, uploaded files, message To prepare your quotation
Contact form Name, email address, phone or WhatsApp number, message To answer your question
Part-number lookup Engine and filter references you send for verification To check a number and quote it
Newsletter signup Email address To send occasional supply updates, if you asked for them
Email Whatever you send, including attachments To answer your enquiry
WhatsApp Your phone number, profile name and the content of the messages, which are also held by Meta Fast confirmation, and photographs
Telephone The caller number and the content of the call Urgent service questions
Website visit IP address, browser type, pages requested and the time of the request Security and site operation

We ask for engine and part information because a filter cannot be quoted without it. We do not ask for payment details, tax identifiers or a full postal address at first contact, and this site has no checkout.

Photographs you upload

The quotation form accepts files. Buyers often photograph a worn filter or an engine dataplate, because a readable image settles what a typed part number cannot.

Send only what the enquiry needs. A photograph of an engine plate can show a serial number, a location and sometimes the people in a workshop. Do not upload images you would not want stored.

Photos submitted for identification form part of the enquiry. If you want to ask about an uploaded photo or request its removal, identify the enquiry and the photo when you contact us.

Engine serial numbers

An engine serial number identifies a build. On its own it is a machine reference; combined with your name, company and email address it becomes part of a record about you. We treat it as personal information and handle it the same way as the rest of your enquiry.

03 Why we use your information

We use it for five purposes, and for no others.

  • To answer your enquiry and prepare a quotation. This is the step you asked us to take before entering into a contract, and it is the reason the form exists.
  • To answer technical questions about a filter, a part number or an installed position, including when you send photographs.
  • To keep order, delivery and accounting records, where you place an order. Some of this is required by law, and we keep it for the period the law sets.
  • To protect the site from spam, automated abuse and attempts to break it.
  • To send supply updates, only if you subscribed to the newsletter. If you receive supply updates, you can ask to stop them by writing to us.

We do not use your enquiry to build a profile, to train a model, or to decide anything about you automatically. No decision with a legal effect on you is made by automated means.

04 Cookies and analytics

A cookie is a small file a site stores in your browser. Some are needed for the site to work. Others are used to measure traffic or to support advertising.

Cookies can support site operation and store preferences. You can clear or block cookies in your browser. Blocking cookies may affect site features. Where the site displays cookie controls, use them to manage the choices available to you.

WordPress sets cookies for logged-in users and, where comments are enabled, for commenters. This site has no customer accounts, so those cookies do not apply to buyers.

05 Who we share it with

We share it with companies that help us run the site and answer enquiries. They act on our instructions, for those purposes only, and they are not permitted to use your information for their own marketing.

Who What they do
Website hosting services Hosts the website and stores form submissions
Form processing services Delivers form submissions to our inbox
Email services Sends and receives enquiry email
Newsletter services, where used Sends supply updates to subscribers
Spam protection services, where used Filters automated form submissions
Meta Platforms Carries WhatsApp messages when you choose that channel

We may also disclose information where the law requires it, where a court or regulator orders it, or where it is needed to establish or defend a legal claim.

WhatsApp

WhatsApp is a choice you make, and it has a consequence worth stating. Messages sent to +86 188 5378 5181 pass through Meta’s systems, and Meta also receives your phone number and profile name. Meta’s own privacy terms apply to that part of the conversation.

WhatsApp is the fastest way to send photographs of a filter or an engine plate. If you would rather not use it, email and telephone reach the same team.

06 Sending information outside your country

Our team operates from China. Enquiries sent from another country may be received and reviewed in China. Communications and website services may process information in other locations depending on the channel used.

Contact us to ask about the processing locations and safeguards relevant to your enquiry.

07 How long we keep it

We keep information only for as long as we need it. Retention depends on the type of record and the purpose for which it is held.

Record How long we keep it
An enquiry that does not become an order As needed to respond and handle related follow-up
A quotation, order or delivery record As needed for the transaction and applicable recordkeeping obligations
Photographs uploaded with an enquiry With the enquiry record
A newsletter subscription Until you unsubscribe, plus a record that you did so
Server and security logs As needed for site operation and security

When a period ends, the record is deleted or anonymised. Records tied to an order may be kept longer where accounting, tax or customs law requires it; in that case the information is restricted to that purpose.

08 Your rights

You can ask us to do any of the following with the information we hold about you.

  • Tell you what we hold, and give you a copy.
  • Correct it if it is wrong or incomplete.
  • Delete it, where we do not need to keep it for a legal or contractual reason.
  • Restrict what we do with it, while a question about it is being resolved.
  • Object to how we use it, where we rely on our legitimate interests.
  • Move it to another organisation in a machine-readable format, where that right applies.
  • Withdraw consent at any time, where we relied on consent, such as the newsletter.

None of these rights is absolute. Where we cannot act on a request, we will tell you why.

How to make a request

Write to [email protected] from, or naming, the address you used in your enquiry. Tell us what you want us to do. We may ask one question to confirm the record is yours, and we will not ask for more identification than that.

We review requests and respond within the time required by applicable law. We may ask for details needed to locate the record and verify your identity.

If you are in the European Union or the United Kingdom

You have the rights set out above under the General Data Protection Regulation and, in the United Kingdom, under UK data protection law. You can also complain to the supervisory authority in the country where you live or work, or where the issue happened; in the UK that is the Information Commissioner’s Office. You do not have to complain to us first.

If you are in mainland China

Under the Personal Information Protection Law you can ask to access or copy your information, correct it, delete it, withdraw consent, and ask us to explain how we process it. You can also complain to the competent authority.

If you are somewhere else

Local law may give you other rights. Write to us and we will tell you what we can do, rather than point you at a clause.

09 How we protect your information

The site is served over HTTPS, so information you send through a form is encrypted in transit. Access to enquiries is limited to the staff who answer them. Photographs and messages are held in the systems named in section 5. We do not take payment details through this site, so no card data is collected or stored here.

No system is completely secure. If a breach affects your information and the law requires us to tell you, we will tell you and the relevant authority without undue delay.

10 Changes to this policy and how to contact us

We update this policy when the site, our suppliers or the law change. The version and effective date at the top of this page always show the current text. If a change materially affects how we use information we already hold, we will say so on this page.

Earlier versions are available on request.

Write to us about your data: [email protected]
Postal location: Jining, Shandong Province, China
Other channels: contact the filter team for telephone and WhatsApp.

If you have an enquiry about a filter rather than about your data, the contact page routes it faster. If you want a price, send the engine model and the part number off the old filter.


This policy describes hl-filters.com and the enquiry channels published on it. It is reviewed whenever a form, a supplier or a hosting arrangement changes.

For a product quotation, send your engine model and filter reference.
