PRIVACY & DATA HANDLING
Privacy notice
How we handle website visits, business enquiries, and data used in authorized advertising services.
1. Who we are
This website is operated by 深圳市迪广隆科技有限公司, referred to in English as Shenzhen Diguanglong Technology Co., Ltd. (Diguanglong Technology), based in Shenzhen, China.
For privacy enquiries, contact admin@diguanglongtech.com.
2. Website visits and hosting
This website introduces our services. It has no account registration, advertising account connection, online payment, report upload, contact form, or analytics scripts added by us. Contact links open your own email application.
The website is hosted on Cloudflare Pages. Cloudflare may process IP addresses, network requests, and other technical information to deliver and protect the website. This technical processing is separate from our local processing of client advertising reports. For the provider's practices, see the Cloudflare Privacy Policy.
3. Email enquiries
Our business and reporting mailbox uses Alibaba Mail (Aliyun enterprise email). When you email us, we receive your email address, message content, and any name, business details, or attachments you choose to provide. We use this information to answer your enquiry, discuss or deliver services, handle feedback, and maintain necessary business correspondence. Email delivery and storage involve our email provider; see the Alibaba Mail Privacy Policy.
Do not send passwords, one-time verification codes, API secrets, full advertising reports, or unrelated personal information through a website enquiry. Agree the scope and transfer method with the project lead before providing service data.
4. Advertising service data
Our current analysis and optimization workflow uses advertising reports that are manually downloaded and imported into our tools with the advertiser's authorization. Reports are processed locally on a computer, not uploaded to a processing server by these tools. The designated project lead views the reports. Reports are not synchronized to cloud drives or computer backups in this workflow.
Before processing client reports, we agree the service purpose, scope, required report fields, authorized handling, and any necessary file transfers with the client. We use the reports for the agreed service and limit their handling to that purpose. This website does not connect to Amazon advertising accounts or provide an Amazon Ads API integration.
Any future API access requires the applicable approvals and advertiser authorization. Changes to our workflow or providers require a corresponding review of client arrangements and this notice.
5. Retention and deletion
For each project, we agree with the client a retention period or deletion conditions for original advertising reports and analysis results. The project lead is responsible for cleaning up the files in accordance with that agreement. There is no single fixed retention period for all projects, and this is not an automatic deletion feature.
For email enquiries and issue records, we retain information while it is needed to respond, provide the agreed service, resolve the issue, or meet applicable recordkeeping obligations. You may contact us to discuss deletion. Where continued retention is required, we explain the relevant reason when responding to your request.
6. Privacy requests
Email us to request access, correction, or deletion of information you have provided, or to ask about a project's data arrangements. Include enough context to identify the enquiry or project. We may need to verify the request; do not send identity documents unless a necessary verification method has first been explained. Requests are assessed against applicable requirements and legitimate retention obligations.
7. Problems and security concerns
Reports sent to our admin mailbox are tracked with an assigned person responsible, handling progress, and outcome. Tool-related problems are referred to the relevant developer. See our security and issue reporting process for what to include in a report.
8. Updates
We review this notice when our website, service workflow, or providers change, and publish the updated notice here. Contact us if you need to clarify how a change affects an existing engagement.
