Privacy Policy

Last updated: May 31, 2026

1. Overview

This Privacy Policy describes how chuhai.tools ("we", "us", or "our") collects, uses, and protects your information when you use our website (chuhai-toolkit.vercel.app) and our iOS app Screenshot Studio.

We are committed to protecting your privacy. We do not sell your personal data. We collect only the minimum information necessary to provide our services.

2. Information We Collect

2.1 Screenshot Studio (iOS App)

Screenshot generation happens entirely on your device. Your app screenshots, template selections, and exported images never leave your phone.

• AI Copy Generation: When you use the AI copy generation feature, the text description you type is sent to our API server to generate marketing copy. No screenshots or images are uploaded. We do not store your text prompts on the server — they are processed in-memory and discarded immediately after generating the response.
• No analytics: The app does not include any third-party analytics SDKs.
• No account required: You can use the app without creating an account.
• Photo Library: We only access your photo library when you explicitly choose to import an app screenshot. We never access your photos automatically.

2.2 chuhai-toolkit.vercel.app (Website)

• Email Subscription: If you choose to subscribe to our newsletter, we store your email address. You can unsubscribe at any time via the link in every email.
• Click Tracking: When you click an affiliate link, we may record an anonymous click event to measure the effectiveness of our recommendations. We do not associate clicks with individual users.
• No Cookies: Our website does not use tracking cookies or store any personal identifiers on your device.

3. How We Use Your Information

• Newsletter: To send you the content you subscribed to (tool updates, guides, recommendations).
• Affiliate Links: Some links on our site are affiliate links. When you click and make a purchase, we may earn a commission at no extra cost to you. This is how we sustain the site.
• Service Improvement: Aggregated, anonymized click data helps us understand which tools are most useful to our readers.

4. Data Sharing

We do not sell, trade, or rent your personal information to third parties.

• Email Provider: If you subscribe to our newsletter, your email address is stored with our email service provider.
• AI API (Screenshot Studio): When generating copy, your text prompt is sent to our API server (hosted on Vercel). No data is shared with third-party AI providers.

5. Data Security

We implement reasonable security measures to protect your information. However, no method of electronic storage is 100% secure. We cannot guarantee absolute security.

6. Children's Privacy

Our services are not directed to children under 13. We do not knowingly collect information from children under 13.

7. Your Rights
