优心忆: Privacy Policy
Last updated: January 22, 2026
优心忆 (“优心忆,” “we,” “our,” or “us”) is an education and learning service for students and lifelong learners. We provide AI study planning, knowledge review, exam preparation tasks, learning progress management, and related support services.
This Privacy Policy explains how we collect, use, retain, and protect personal information when you use the 优心忆 website, mobile applications, and related services (collectively, the “Services”).
1. Core Privacy Principles
We process information only as needed to provide learning services.
We do not sell personal information, study records, or behavioral data.
We use reasonable technical and organizational measures to protect accounts, learning materials, and service data.
You may request access, correction, deletion of personal information, or account deletion in accordance with applicable law.
2. Information We Handle
2.1 Information You Provide
When you register, use learning features, or contact support, you may provide information such as nickname, avatar, email address, phone number, learning goals, exam direction, task preferences, feedback, and support communications.
If you use study planning, mistake review, knowledge memory, progress tracking, or related features, we may process learning materials, practice records, task completion status, saved content, and study preferences that you choose to submit. This helps us provide personalized learning recommendations and service experiences.
2.2 Automatically Processed Technical Information
To keep the Services stable, secure, and improving, we may process limited technical information such as application version, device type, operating system, page visits, feature usage, crash logs, diagnostic data, and necessary network information.
This information is used for account security, service operation, performance optimization, troubleshooting, and abuse prevention. Where practical, analytics and diagnostic data are aggregated or anonymized.
3. How We Use Information
We use information to provide and maintain education and learning services, including creating study plans, syncing learning progress, displaying task reminders, improving AI learning suggestions, handling account and support requests, protecting service security, and complying with legal obligations.
We will not use your learning content for unrelated commercial promotion without your consent.
4. Third-Party Services
We may use third-party service providers for website hosting, data storage, notifications, analytics, customer support, or AI capabilities. These providers may process information only as needed to support the Services and are expected to follow applicable data protection obligations.
If you access third-party websites or services through external links, their privacy practices are controlled by those third parties. Please review their policies before use.
5. Data Retention and Deletion
We retain personal information for as long as necessary to fulfill the purposes described in this Policy, unless a longer retention period is required or permitted by law.
You may submit account deletion or data deletion requests through the application. After necessary verification, we will delete or anonymize relevant personal information unless otherwise required by law.
6. Your Rights
Subject to applicable law, you may request access to, correction of, copying of, or deletion of your personal information, withdraw consent, delete your account, or contact us with questions or complaints about personal information processing.
We will respond within a reasonable period after verifying your identity.
7. Children and Minors
优心忆 cares about protecting minors’ personal information. Minors should obtain consent from a parent or guardian before using the Services. If we learn that we collected a minor’s personal information without required guardian consent, we will take appropriate steps to delete it or otherwise handle it as required by law.
8. Changes to This Policy
We may update this Privacy Policy to reflect changes in the Services, legal requirements, or operational needs. The “Last updated” date reflects the most recent revision.
