1. Introduction
Chinglish Book is an independently operated educational website based in the United States. This Privacy Policy explains how information is collected, used, stored, and shared when users visit the website, create an account, or use learning features.
2. Information Users Provide
Information users provide may include a username, email address, account profile information provided voluntarily, messages sent to the contact email, and information included in privacy, export, correction, or deletion requests. Account authentication uses a password hash. The site does not store users’ plaintext passwords.
3. Learning Information
When an account holder uses Learn features, the site may store the Learning Group and Version, lesson and item progress, learned or review states, practice usage where stored, checkpoint attempts, question and answer snapshots, scores, completion status, and last activity time. This information supports course continuity and reproducible learning versions.
4. Automatically Collected Information
The website and its infrastructure may automatically process an IP address, browser and device information, requested URLs, referrer, access time, error and security logs, cookie and local-storage identifiers, and approximate location derived by infrastructure or analytics services. The site does not claim to collect precise geolocation.
5. Purposes
Information is used to provide accounts and login, save learning progress, resume courses across devices, operate Practice and Checkpoint features, protect security and prevent abuse, diagnose errors, maintain and improve the website, measure aggregate usage, respond to contact and privacy requests, and comply with legal obligations.
6. Cookies and Local Storage
Essential cookies
Essential cookies may be used for WordPress login and authentication, security and session functions, and Cloudflare security functions when enabled. These functions help users sign in and help protect the service.
Local storage
Browser local storage may hold anonymous lesson progress, the current learning position, and temporary browser-only states. Anonymous local-storage progress does not create a Chinglish Book database account record, remains only in that browser, may be lost when browser storage is cleared, and is not automatically merged into a later account.
Analytics
Chinglish Book currently uses Cloudflare Web Analytics for aggregate website performance and usage measurement. Cloudflare Web Analytics is designed to operate without analytics cookies or cross-site individual tracking. Cloudflare security services may separately use essential cookies when necessary to protect network traffic.
Google Analytics is not currently enabled on Chinglish Book. It may be introduced later only after this Privacy Policy and the applicable consent configuration have been reviewed and updated.
Advertising
Chinglish Book does not currently use advertising services or advertising cookies.
7. Third-Party Services
- Cloudflare — DNS, content delivery, security, and Web Analytics.
- Rank Math SEO — WordPress SEO functionality.
- Hosting provider — infrastructure used to host WordPress and site data. The production hosting provider will process server and account data as necessary to host and secure the website. This Privacy Policy will be updated if the provider or processing practices materially change.
- Essential account email provider — may deliver password reset, account security, and service messages. Marketing email is not currently used.
Google Analytics will be listed as an active service only if it is actually enabled after the required privacy and consent review.
8. Sale and Advertising
Chinglish Book does not currently sell personal information. Chinglish Book does not currently use personal information for targeted advertising. This statement does not attempt to characterize every disclosure under every privacy law; applicable service-provider processing is described in this Policy.
9. Data Retention
Account information is generally retained while an account remains active.
Learning progress and checkpoint records are generally retained while the account remains active, unless deletion is requested or retention is required for security, dispute resolution, or legal compliance.
Contact and privacy-request records may be retained for a reasonable period to document and respond to the request. Server and security logs are retained only as reasonably necessary for operations, security, and troubleshooting.
Deleted information may remain temporarily in backup copies until those backups are replaced through the normal backup-rotation process.
10. User Rights and Choices
Depending on applicable law, users may request access to or export of their data, correction of account information, deletion of an account and learning data, or objection to or limitation of certain processing. Users may also clear cookies and local storage and disable analytics through available browser or consent controls.
Requests may be sent to chinglishbook@outlook.com. Chinglish Book may need to verify the requester’s identity before acting on a request.
11. California Users
California residents may have rights under applicable California privacy laws, depending on the law and whether Chinglish Book meets the relevant applicability requirements. Chinglish Book does not currently sell personal information or use personal information for targeted advertising. Requests may be sent to chinglishbook@outlook.com.
12. Do Not Track and Privacy Signals
Browsers may offer Do Not Track or other privacy signals. Because there is not a single universally accepted standard for all such signals, the site may not respond to every signal in the same way. Where a legally required privacy signal applies to the site’s processing, Chinglish Book will evaluate and honor it as required.
13. International Visitors
The website is operated from the United States. Information may be processed in the United States and in locations where service providers operate.
14. Children
Chinglish Book is not directed to children under 13. Users under 13 may not create an account or submit personal information. Chinglish Book does not currently offer a parental-consent process for users under 13. If Chinglish Book learns that personal information was collected from a child under 13, it will take reasonable steps to delete that information.
15. Security
Chinglish Book uses reasonable safeguards appropriate to the service, including HTTPS on production, password hashing, access controls, updates and monitoring, security and error logging, and Cloudflare protections where enabled. No website or storage system can guarantee absolute security.
16. Changes
