1. Introduction

This Privacy Policy explains how Shenzhen Yiyun Light Garment Technology Co., Ltd. (“we”, “us”) collects, uses, stores, shares, and deletes personal information when you use CHUYAN AI / HI CHUYAN (the “Service”) at https://hichuyan.com/.

The Service provides AI image generation, video generation, intelligent retouching, reference collection, and creative workflows. If you do not agree with this Policy, please do not use the Service.

This Policy does not cover third-party products or websites, including AI model providers and Pinterest itself, which have their own policies.

2. Information we collect

2.1 Information you provide

2.2 Information collected automatically

2.3 Information from other sources

3. How we use information

We use personal information only as needed to operate and improve the Service, including to:

We do not sell personal information and do not use it for cross-app targeted advertising.

4. AI processing

When you start a generation or edit, the relevant prompt and reference media (which may include a Pinterest image you selected) are sent over HTTPS to the configured third-party AI providers so they can complete that request.

We do not use your prompts, uploads, or Pinterest data to train our own foundation models. Third-party providers process content only to fulfill the request you initiated and under their own terms.

Do not upload sensitive personal data, images of minors, or confidential business materials you are not allowed to process.

5. Pinterest API and data

5.1 Non-affiliation

CHUYAN AI / HI CHUYAN is independently developed and operated by Shenzhen Yiyun Light Garment Technology Co., Ltd. We are not affiliated with, endorsed by, sponsored by, or officially partnered with Pinterest, Inc. Pinterest names, marks, and APIs belong to Pinterest. We call the official Pinterest API only after a user grants OAuth authorization, in accordance with Pinterest’s developer terms.

5.2 Pinterest data we may access

Only after you click “Connect Pinterest” and complete official OAuth may we access:

We do not ask for your Pinterest password or session cookies, and we do not scrape other people’s accounts.

5.3 Purpose of use

Pinterest data is used only to show your own reference Pins and boards inside CHUYAN AI, and, if you actively select an image, to use it as a reference for the current generation job. We do not use Pinterest data for advertising, data brokerage, or unrelated profiling.

5.4 No sale or redistribution of Pinterest data

We do not sell, rent, resell, or redistribute Pinterest API data (including account information, Pins, boards, and tokens) to any third party. We do not provide Pinterest data to advertising networks, data brokers, or other advertising services. A reference image is sent to an AI provider only when you select it for a generation job.

5.5 Deletion when Pinterest is disconnected

We delete stored Pinterest access tokens, refresh tokens, and cached account identifiers without undue delay, and in any event within 30 days, when any of the following occurs:

  • you disconnect Pinterest inside CHUYAN AI;
  • you revoke the app in your Pinterest account settings;
  • you delete your CHUYAN AI account;
  • Pinterest or applicable law requires deletion;
  • the data is no longer needed for the authorized purpose.

After disconnection, the Service can no longer read your Pinterest content. A limited amount of security or audit logs may be retained in de-identified form where legally required.

6. Sharing

We do not share identifiable personal information except:

7. Security

We use reasonable technical and organizational measures, including HTTPS/TLS, access control, encrypted storage of Pinterest tokens, and least-privilege practices. No internet transmission is perfectly secure. Please use a strong password and keep your own copies of important work.

8. Retention

We keep information for as long as needed to provide the Service. Creative content remains while your account and projects exist. After account deletion we delete or de-identify personal data, except records we must keep for legal, tax, or security reasons.

9. Your rights

Subject to applicable law, you may:

Email chuyanstudio@gmail.com. After we verify your identity we will respond as soon as reasonably possible, usually within 15 business days.

10. Cookies and local storage

We use necessary cookies and local storage to keep you signed in, remember preferences such as watermark settings, and protect the Service. We do not use advertising cookies and do not share browsing activity with ad networks.

11. Children

The Service is not directed to children under 13, or the higher minimum age in your jurisdiction. If we learn that we have collected such information, we will delete it. Guardians may contact us if they believe a child has provided personal data.

12. Updates

We may update this Policy. Material changes will be reflected in the “Last updated” date and, where appropriate, notified in the Service. Continued use after the effective date means you accept the revised Policy.
