Foshan Jiarong Lanting Intelligent Technology Co., Ltd. ("we", "us") takes your personal information and privacy seriously. This policy applies to all products and services we develop and operate, including our website and the mobile app Runju Miaotu (润桔妙图) (together, the "Product"). Please read it carefully before using the Product, especially the parts in bold. By using the Product you confirm that you have understood and agree to this policy. In case of any discrepancy between this English version and the Chinese version, the Chinese version prevails.
1. Information we collect
We follow the principle of data minimisation and collect only what a feature needs.

We do not collect your contacts, precise location, SMS content or clipboard, and we do not read any files on your device that you have not explicitly chosen.
2. How we use information
- To provide, maintain and improve the Product;
- To process the images you upload and produce results. Images are used only to complete the task you initiated; the originals and results are kept on our servers for no more than 7 days and are then deleted automatically. You can also delete them manually in the app at any time;
- To send you necessary notices about your account and the service (verification codes, order information);
- To analyse usage and improve the experience, using de-identified data;
- To comply with legal obligations.
We do not use your uploaded images to train models or for advertising, and we never sell your personal information to third parties.
3. Third-party services and SDKs
Some features rely on third-party services. Each provider processes information only as needed to deliver its service and is bound by its own privacy policy:
| Provider | Purpose | Information involved |
|---|---|---|
| AI image-generation provider | Generate images from your material and description | Images you upload, text descriptions (no account identity) |
| Cloud hosting provider | Server hosting, temporary file storage | Uploaded files, access logs |
| Push notification service (if enabled) | Notify you when a task finishes | Device identifier, push token |
| Payment platform (if paid features are enabled) | Complete payment | Order information; payment account handled by the platform |
The specific providers and SDKs are listed in the app under Settings → Privacy → Third-party sharing list, and are updated with each release.
4. Storage and protection
Your information is stored on servers located in the People's Republic of China. We use transport encryption (HTTPS / TLS), access controls and data isolation to protect it. Unless the law requires otherwise, we keep information only as long as necessary for the purposes in this policy; after you delete your account, we delete or anonymise your personal information.
No system is completely secure. If a security incident affecting personal information occurs, we will notify you and take remedial measures as required by law.
