Privacy Policy

Link Display, operating as 济南联呈嗒放网络科技服务有限公司 (Jinan Liancheng Dafang Network Technology Service Co., Ltd.), is committed to protecting the privacy and security of personal data entrusted to us. This Privacy Policy explains what information we collect, how we use it, the legal basis for processing, your rights regarding that information, and the measures we take to safeguard it.

1. Scope and applicability

This policy applies to all personal data collected through the Link Display website at linkdisplay.lol, through our contact forms, email correspondence, telephone communications, and any services we provide as part of our computer systems design and network technology operations. This policy covers interactions with visitors, prospective clients, active clients, vendors, and business partners.

Link Display acts as a data controller for the personal data described in this policy. Our registered address is Room 1103, 11F, Building 1, Zhihui Building, Gaoxin District, Jinan, Shandong 250000, China.

2. Categories of data we collect

2.1 Information you provide directly

When you contact us via our website form, email, or telephone, we collect the information you voluntarily provide. This includes your name, email address, telephone number, company name, job title, the content of your message, and any attachments or supporting materials you choose to share. We collect this information for the purpose of responding to your inquiry and evaluating whether we can assist with your infrastructure or systems design needs.

If you enter into a service agreement with us, we collect additional information necessary for contract performance — billing details, project specifications, technical architecture documents, system credentials (secured separately), and communication records.

2.2 Information collected automatically

When you visit our website, our hosting infrastructure automatically collects standard server log data. This includes your IP address, browser type and version, operating system, referring URL, pages visited, timestamps, and HTTP status codes. This data is processed for security monitoring, performance optimization, and aggregate traffic analysis. We do not use third-party analytics services, advertising trackers, or fingerprinting scripts on our website.

2.3 Cookies and similar technologies

Our website uses a minimal set of strictly necessary cookies required for session management and security. We do not deploy advertising cookies, third-party tracking cookies, or social media pixels. No cookie consent banner is presented because we do not engage in any form of behavioral tracking or profiling.

You may configure your browser to reject all cookies; doing so will not impair your ability to access the informational content on our website.

3. Purpose and legal basis for processing

3.1 Contractual necessity

We process personal data where necessary to perform a contract with you or to take steps at your request before entering into a contract. This covers responding to service inquiries, preparing proposals, delivering agreed-upon systems design and network integration services, and processing payments.

3.2 Legitimate interests

We process personal data where we have a legitimate business interest that is not overridden by your data protection rights. Legitimate interests include: maintaining the security and integrity of our network infrastructure, responding to client support requests, improving our service delivery processes, and communicating service-related updates to existing clients.

3.3 Legal obligations

We process personal data where necessary to comply with applicable laws and regulations, including tax record-keeping requirements, regulatory reporting, and responding to lawful requests from government authorities.

3.4 Consent

Where processing is based on consent, we will obtain your explicit consent at the point of collection. You may withdraw consent at any time by contacting us at mobile-team@linkdisplay.lol. Withdrawal does not affect the lawfulness of processing carried out before the withdrawal.

4. Data sharing and disclosure

Link Display does not sell, rent, trade, or otherwise monetize personal data. We may share personal data only in the following limited circumstances:

• Service providers and subcontractors: We engage third-party providers for specific operational functions — cloud infrastructure hosting, email delivery, payment processing, and professional services. These providers are contractually bound to process data solely on our documented instructions and are prohibited from using data for their own purposes. We conduct due diligence on all providers to verify their security posture.
• Legal compliance: We may disclose data where required by law, court order, or governmental regulation. We will notify you of such disclosure where legally permitted to do so.
• Business transfers: In the event of a merger, acquisition, or sale of all or a portion of our assets, personal data may be transferred as part of that transaction. We will notify affected individuals and provide an opportunity to opt out where applicable.

5. Cross-border data transfers

Link Display is headquartered in Jinan, Shandong, China. Personal data we collect is stored and processed primarily within China. Where data is transferred to servers or service providers located outside your country of residence, we implement appropriate safeguards — including standard contractual clauses, data processing agreements, and technical measures — to ensure an equivalent level of protection.

6. Data retention

We retain personal data only for as long as necessary to fulfill the purposes for which it was collected, or as required by applicable law. Our retention framework operates as follows:

• Inquiry and correspondence data: Retained for 24 months from the date of last communication, after which it is securely deleted.
• Client project data: Retained for the duration of the service agreement plus 7 years following project completion, to satisfy legal and audit requirements.
• Server logs: Retained for 90 days on a rolling basis, then purged.
• Financial and billing records: Retained for the period required by applicable tax law, typically 10 years from the date of transaction.

At the end of the applicable retention period, data is either irreversibly anonymized or securely destroyed using methods appropriate to the data type and storage medium.

7. Data security

We implement technical and organizational measures designed to protect personal data against unauthorized access, alteration, disclosure, or destruction. Our security program includes:

• Encryption of data in transit using TLS 1.3;
• Encryption of data at rest using AES-256;
• Network segmentation with strict access control lists;
• Multi-factor authentication for all administrative access;
• Regular vulnerability scanning and penetration testing;
• Security incident response procedures with defined escalation paths;
• Employee training on data protection and confidentiality obligations;
• Physical security controls at our office premises in Zhihui Building, Jinan.

While we apply industry-standard practices, no method of electronic storage or transmission is absolutely secure. We cannot guarantee absolute security, and we encourage you to take reasonable precautions when transmitting sensitive information.

8. Your data protection rights

Depending on your jurisdiction, you may have the following rights regarding your personal data:

• Right of access: You may request a copy of the personal data we hold about you, along with information about how we process it.
• Right to rectification: You may request that we correct inaccurate or incomplete personal data we hold about you.
• Right to erasure: You may request deletion of your personal data where there is no compelling reason for its continued processing.
• Right to restrict processing: You may request that we limit the processing of your personal data in certain circumstances — for example, while we verify the accuracy of data you have contested.
• Right to data portability: You may request a copy of your personal data in a structured, commonly used, machine-readable format, and have it transmitted to another controller where technically feasible.
• Right to object: You may object to processing based on legitimate interests, including profiling. We will cease processing unless we demonstrate compelling legitimate grounds that override your interests, rights, and freedoms.
• Right to withdraw consent: Where processing is based on consent, you may withdraw that consent at any time without affecting the lawfulness of processing carried out before withdrawal.
• Right to lodge a complaint: You have the right to lodge a complaint with a supervisory authority in your country of residence if you believe our processing of your personal data violates applicable data protection law.

To exercise any of these rights, contact us at mobile-team@linkdisplay.lol with the subject line Data Protection Request. We will verify your identity before processing the request and will respond within 30 calendar days. Where the request is complex or numerous, we may extend this period by up to an additional 60 days, and we will inform you of any such extension within the initial 30-day window.

9. Children's privacy

Our services are directed at businesses and professional organizations. We do not knowingly collect personal data from individuals under the age of 18. If we become aware that we have inadvertently collected personal data from a minor, we will promptly delete it. If you believe a minor has provided us with personal data, please contact us immediately.

10. Third-party links

Our website may contain links to external websites that are not operated by Link Display. We are not responsible for the privacy practices or content of third-party sites. We encourage you to review the privacy policy of every website you visit.

11. Policy updates

We review this Privacy Policy at least annually and update it as necessary to reflect changes in our data processing practices, legal obligations, or regulatory guidance. Material changes will be communicated by posting the updated policy on this page with a revised effective date. Where changes are significant, we will provide additional notice — such as by email to active clients or by a prominent notice on our website.

We maintain a version history of this policy internally. You may request a copy of any previous version by contacting us.
