SECOND WIND LIMITED ("we," "us," or "our") provides CleanRead AI, a reader and listening application that helps users import reading materials, extract text, create summaries, generate study audio, and manage reading progress. This Privacy Policy explains what information we collect, how we use it, and the choices available to you.
1. Information We Collect
Account information
When you create an account or sign in, we may collect identifiers such as your email address, authentication provider identifiers, account status, subscription status, and support correspondence.
Reading materials and user content
CleanRead AI lets you import PDFs, scans, screenshots, web links, pasted text, notes, and other study materials. We process the content you submit so the app can extract text, organize documents, generate summaries, identify key terms, create listenable sections, produce audio, and save your progress.
Usage, device, and diagnostic data
We may collect app usage events, feature interactions, device type, operating system, app version, IP address, crash logs, performance data, request metadata, and similar diagnostic information. This helps us operate, secure, debug, and improve the service.
Purchase and entitlement data
If you buy a subscription or add-on, payment is processed by the App Store, Google Play, or another authorized store. We do not receive your full payment card details. We may receive purchase identifiers, product identifiers, entitlement status, renewal status, cancellation status, and usage balances needed to provide paid features.
Local cache data
The app may store document metadata, reading progress, generated audio, and other cached files on your device to improve speed and offline or low-connectivity use. You can clear local app data through in-app controls where available or through your device settings.
2. How We Use Information
We use the information described above to:
- Provide, maintain, and improve CleanRead AI.
- Import, parse, OCR, summarize, structure, and convert your materials into audio.
- Sync documents, account state, subscription access, usage limits, and reading progress.
- Process purchases, restore purchases, grant entitlements, and prevent abuse.
- Provide customer support and respond to your requests.
- Monitor reliability, diagnose technical issues, prevent fraud, and secure the service.
- Comply with legal obligations and enforce our terms and policies.
3. AI Processing and User Materials
CleanRead AI may send the materials you submit, extracted text, and related prompts or metadata to our servers and service providers so we can perform OCR, text extraction, summarization, text-to-speech generation, and related document processing. You should only upload or paste materials that you have the right to use and process through the service.
Generated summaries and audio may be imperfect. You are responsible for reviewing output before relying on it for study, work, legal, medical, financial, or other important decisions.
4. Sharing of Information
We do not sell your personal information. We may share information with service providers that help us operate CleanRead AI, including cloud hosting, authentication, analytics, crash reporting, payment entitlement management, OCR, language processing, text-to-speech, email, security, and customer support providers. These providers may process information only as needed to provide services to us.
We may also disclose information if required by law, to protect the rights and safety of users or others, to investigate abuse, or as part of a merger, acquisition, financing, or sale of assets.
5. Data Retention
We retain personal information and user content for as long as needed to provide the service, maintain your account, comply with legal obligations, resolve disputes, enforce agreements, and protect the service. Some diagnostic, security, and backup records may be retained for a limited period after deletion from active systems.
6. Your Choices and Rights
You may access, update, export, or delete certain information through the app where those controls are available. You may also contact us to request access, correction, deletion, or other privacy rights available under applicable law. You can manage subscriptions through the App Store or Google Play account used to purchase them.
You can control app permissions, notifications, storage, and network access through your device settings. Some features may not work correctly if required permissions or network access are disabled.
7. Security
We use reasonable administrative, technical, and organizational safeguards designed to protect information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
8. International Transfers
We are based in Hong Kong and may process information in other countries where we or our service providers operate. Those countries may have data protection laws that differ from the laws of your location.
9. Children's Privacy
CleanRead AI is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, please contact us so we can take appropriate action.
10. Changes to This Policy
We may update this Privacy Policy from time to time. When we make changes, we will update the "Last Updated" date above. Your continued use of CleanRead AI after a policy update means you accept the updated policy.
