1. Who we are
KingKung is a cross-border ecommerce SaaS platform operated by Zhengzhou Jindouyun Industrial Co., Ltd.（郑州金豆云实业有限公司）. We provide software for advertising management, store management, reporting, and automation.
Registered office: Room 1001, Unit 1, Building 5, Mingxuan International, No. 1 Baizhuang Street, Zhengdong New District, Zhengzhou, Henan, China （河南省郑州市郑东新区白庄街1号铭轩国际5号楼1单元1001）.
2. Purpose of processing
We process data to deliver KingKung SaaS features to business customers, including campaign management, store management, analytics, automation, troubleshooting, and security.
3. Amazon Data Protection
3.1 Amazon OAuth
Access to Amazon Ads API and/or Selling Partner API (SP-API) requires official Amazon OAuth (Login with Amazon / Amazon authorization). We do not collect, buy, sell, or store Amazon passwords. Developer credentials are not shared with unauthorized parties.
3.2 Amazon Data Usage
Amazon data is accessed only within the permissions granted by each customer through Amazon OAuth, and is used only to provide the requested software features:
- Account metadata — connect the correct seller / Ads profile
- Campaign structure — manage Ads campaigns in granted scopes
- Store management data — orders, inventory, listings, reports in granted SP-API roles
- Performance metrics — reporting and optimization
- Operational logs — security and audit
Amazon data is never shared across customers. We do not sell Amazon data or use it for unauthorized interest-based advertising.
3.3 Amazon Data Retention
Operational Amazon data is retained while the customer engagement / authorization is active. Retention may also continue for a limited period needed for troubleshooting, dispute handling, security review, or legal / Amazon policy requirements.
3.4 Amazon Revocation
Customers may revoke KingKung’s access at any time through Amazon’s authorization management. When authorization is revoked, API access tokens are invalidated and platform access for that account is disabled.
3.5 Amazon Deletion
After authorization revocation or a written deletion request, we delete or anonymize customer Amazon operational data within 90 days, except where longer retention is required by law or Amazon / platform policy (for example audit, dispute, or security incident records).
4. Security
Role-based access, least privilege, per-customer isolation, audit logs, encrypted token storage, and HTTPS for all KingKung web traffic.
5. Sharing
We do not sell customer or Amazon data. We may use infrastructure providers strictly as needed to host and operate the SaaS platform, under confidentiality and security controls, or disclose information when required by law or platform investigations.
6. Other platforms
Where KingKung connects to Shopee, Lazada, TikTok, Meta, or Google under those platforms’ approved programs, the same principles apply: official authorization only, least privilege, no password collection, and use limited to the agreed software features.
