We collect information in two ways: information you actively submit, and technical information your browser sends automatically.

If you contact us directly by email or messaging application instead of using the form, we receive whatever information you include in that message, together with the address or number you send it from.

We do not ask for, and you should not send us, sensitive categories of personal data such as government identification numbers, financial account credentials, or health information through this website.

We use the information you provide only for purposes connected to your inquiry and to the commercial relationship that may follow:

• Reviewing your technical requirement and preparing a quotation or pro forma invoice
• Asking follow-up questions needed to specify equipment, materials, or certification correctly
• Coordinating supplier selection, inspection, documentation, logistics, and after-sales support
• Maintaining records of quotations, orders, and correspondence for accounting and contractual purposes
• Complying with export documentation, customs, tax, and other legal obligations
• Protecting the website against spam submissions, abuse, and security incidents

We do not use inquiry data for automated decision-making or profiling, and we do not add inquiry contacts to unrelated marketing lists.

This website does not run advertising networks, remarketing pixels, or behavioural analytics. We do not build visitor profiles and we do not follow you across other websites.

The website platform may set a small number of strictly necessary cookies required for basic operation, such as maintaining a session or preventing repeated form submission. These cookies are not used for advertising.

You can block or delete cookies in your browser settings. Blocking strictly necessary cookies may prevent inquiry forms from working correctly.

Some page assets are delivered from third-party networks. When your browser requests those assets, the provider receives your IP address and basic request information as a technical necessity of delivering the file.

If you contact us through a third-party messaging application, that conversation is also governed by the privacy policy of the platform operator, which we do not control.

We do not sell, rent, or trade your information.

We share information only where it is necessary to fulfil your request or to meet a legal obligation:

• Manufacturing partners and suppliers — limited technical requirements needed to prepare a quotation or produce equipment. We share the specification, not your full contact record, unless direct coordination is required and you are aware of it.
• Inspection, logistics, and customs agents — consignee and shipment details required to move goods and clear customs.
• Professional advisers — accountants, auditors, banks, or legal counsel, where required for a transaction.
• Authorities — where disclosure is required by applicable law, regulation, or a valid legal request.

Where a supplier or agent processes information on our behalf, we require that it be used only for the agreed purpose.

We are established in the People’s Republic of China and serve customers internationally. Information you send us will therefore be received and stored in China, and may be transmitted to manufacturing partners, inspection agents, or logistics providers located in China or in the destination market.

If you are located in a jurisdiction that restricts international transfers of personal data, please only send the information you are permitted to share. By submitting an inquiry, you understand that your business contact details will be processed outside your own country in order to respond to you.

We keep inquiry records for as long as needed to respond to you and to support any resulting commercial relationship. Where a transaction takes place, contract, invoice, shipping, and tax records are retained for the period required by applicable accounting and export regulations. Inquiries that do not lead to a transaction are removed once they are no longer commercially relevant.

We use encrypted connections for this website, restrict access to inquiry records to staff who need them, and maintain reasonable administrative and technical safeguards. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Subject to the law that applies to you, you may ask us to:

• Confirm what information about you we hold, and provide a copy of it
• Correct information that is inaccurate or out of date
• Delete information we no longer need to keep for legal or contractual reasons
• Stop sending you commercial follow-up messages

Send your request to sales@oasispetrotech.com from the address used in your original inquiry, so that we can identify the record. We will respond within a reasonable period, and in any case within the time limit set by applicable law.

We may need to retain certain records even after a deletion request where an export, tax, or contractual obligation requires it. If so, we will tell you which records and why.
