Privacy Policy
Last updated: June 21, 2026
Lingxi Copywriting is an AI copywriting tool operated under Hewu Labs. This Privacy Policy explains how we collect, use, store, and protect information when you use our website and services.
Information We Collect
We may collect the following types of information:
Content you input
When you use Lingxi Copywriting to generate copy, you provide content such as product descriptions, selling points, audience, and call-to-action text. We use this input only to generate the requested copywriting output.
Account information
If you create an account or sign in using a third-party login provider such as Google, we may receive basic account information such as your name, email address, and profile image.
Usage information
We may collect basic usage data, such as generation count, template and platform selections, error logs, browser type, device information, and approximate location based on IP address.
How We Use Your Information
We use your information to:
- Provide AI-powered copywriting generation
- Process your input content and generate tailored copy
- Manage free usage limits
- Provide account login and authentication
- Respond to support requests and feedback
- Improve service reliability, security, and performance
- Prevent abuse, fraud, or misuse of the service
Input Content
Input content is processed automatically.
We do not manually review your input content unless required for troubleshooting, abuse investigation, legal compliance, or with your explicit permission.
Generated copywriting output is streamed to your browser and is not stored on our servers after the generation session completes.
We do not use your input content to train AI models.
We do not sell your input content or generated copy.
We do not share your input content with third parties except when necessary to provide the service (e.g., the LLM API provider), comply with legal obligations, prevent abuse, or protect the security of the service.
Content Security
We use reasonable technical and organizational measures to protect your input content and personal data. However, no internet-based service can guarantee absolute security. You should not input highly confidential, sensitive, classified, or legally restricted information unless you understand and accept the risks of using an online AI copywriting service.
Third-Party Services
We may use third-party services for hosting, AI generation, authentication, database storage, email, or infrastructure. These providers may process limited information only as necessary to help us operate the service. Examples may include: hosting and deployment providers, AI language model providers, authentication providers, database providers, email and support tools, or error monitoring tools.
Data Retention
Input content is not permanently stored; it is processed in-memory during generation and discarded afterward. Account and usage records may be retained for as long as necessary to provide the service, comply with legal obligations, resolve disputes, prevent abuse, and enforce our agreements.
Your Rights
Depending on your location, you may have rights to access, correct, delete, or restrict the use of your personal information. You can contact us to request access, correction, or deletion of your personal information.
Children's Privacy
Lingxi Copywriting is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13.
Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page.
