Last Updated: 2026年2月16日

Thank you for using iSpell! We deeply understand the importance of personal information to you and will do our utmost to protect the security and reliability of your personal information. We are committed to maintaining your trust and adhering to the following principles to protect your personal information: consistency of rights and responsibilities, clear purpose, consent-based choice, minimum necessary usage, security assurance, subject participation, openness, and transparency.

This “Privacy Policy” (hereinafter referred to as “this Policy”) is intended to explain how we collect, use, store, and share your personal information, and how you can access, update, delete, and protect this information.

1. How We Collect and Use Your Information

When you use our services, we adhere to the “minimum necessary” principle and collect and use the following information related to you:

Information You Provide：When you register an account, you need to provide your email address as the login name. When you log in with a password, you need to set a password, and we will store your password using one-way hash encryption.
Third-Party Service Information：If you choose to log in using a third-party account (such as WeChat, QQ, Google, GitHub), you authorize us to obtain publicly registered information from that third-party platform (such as nickname, avatar).
Service Usage Information：To provide the core word memorization function, we will record your learning data, including your word book selection, learning plan settings (such as daily word count), word mastery status, and review progress.
Device and Technical Information：We may automatically collect certain technical information, such as IP address, browser type, and operating system. We use `localStorage` or `sessionStorage` to store your authentication status (using `localStorage` if you select “Remember Me”) and app preferences (such as theme settings).

2. How We Use Your Information

We strictly comply with the provisions of laws and regulations and agreements with users, and use the collected information for the following purposes:

Providing Core Services：Used for identity verification (login, registration, password reset), and to store and synchronize your learning progress.
Sending Important Notifications：When you register or reset your password, we need to use your email address to send you a verification code through a third-party service provider such as Tencent Cloud.
Maintenance and Improvement：Used to analyze the usage of our services to troubleshoot, improve functionality, and user experience.
Security Assurance：Used to prevent, detect, and investigate fraud, security threats, illegal acts, or breaches of agreements, policies, or rules with us or our affiliates, to protect your legitimate rights, those of other users, or ours.

3. Sharing, Transfer, and Public Disclosure of Information

We will not sell your personal information to any company, organization, or individual.

We will only share your personal information in the following circumstances:

With Your Explicit Consent：We will share your personal information with other parties after obtaining your explicit consent.
Sharing with Authorized Partners：Solely for the purpose stated in this Policy, some of our services will be provided by authorized partners (e.g., Tencent Cloud for SMS and email services). We will only share your information for legitimate, proper, necessary, specific, and explicit purposes, and only share the information necessary to provide the service.
Legal Requirements：We may share your personal information externally based on the requirements of laws, regulations, legal procedures, or mandatory requirements from government authorities.

4. Your Rights

In accordance with relevant Chinese laws, regulations, and standards, we ensure that you exercise the following rights over your personal information:

Access and Correction：You have the right to access and correct your account information (e.g., nickname, avatar).
Deletion：You can clear your local device's session information (`sessionStorage`) by “Log Out”. If you checked “Remember Me”, you will also need to manually clear the data in your browser's `localStorage`.
Account Deletion：You can contact us at any time to request account deletion. Upon receiving your request, we will stop providing services to you and delete or anonymize your personal information (unless otherwise stipulated by laws and regulations).

5. Information Storage and Security

We have implemented industry-standard security protection measures to safeguard the personal information you provide, preventing unauthorized access, public disclosure, use, modification, damage, or loss of data.

For example, we use Bcrypt hash encryption to store your password in a one-way encrypted format, ensuring that your original password cannot be retrieved even if the database is leaked.

6. Children's Privacy

Our services are primarily intended for adults. Children (whom we consider to be anyone under the age of 14) should not create their own user accounts without the consent of a parent or guardian.

7. Policy Changes

We reserve the right to modify this Policy at any time. The modified Policy will be published on this page and will replace the old version. We recommend that you review this Policy regularly. Your continued use of this service after the Policy has been modified constitutes your acceptance of the modified Policy.
