Privacy Policy
Last Updated: June 3, 2026
We value your privacy. This policy explains how we collect, use, store, and protect your personal information. By using our service, you consent to the data processing practices described in this policy.
Information Collection
We collect: (1) Account information — name, email address, password you provide during registration; (2) Learning content — PDFs, documents, video links, and other study materials you upload; (3) Usage data — login frequency, feature usage, learning progress; (4) Device information — browser type, operating system, IP address (for security purposes); (5) Payment information — processed through Stripe; we do not directly store complete credit card numbers.
Information Usage
Your information is used to: (1) provide and improve our AI learning services; (2) generate personalized study plans, test questions, and analysis reports; (3) maintain your account and learning progress; (4) send service-related notifications (such as feature updates and security alerts); (5) perform anonymous statistical analysis to improve our product. We do not use your personal data to train AI models.
AI Data Processing
Your learning content and conversation history are sent to third-party AI service providers (such as OpenAI, Anthropic) for processing to generate analysis results. These providers are contractually bound not to use your data for their own purposes. Conversation history is stored to maintain context continuity across sessions.
Data Security & Storage
We employ industry-standard security measures to protect your data: all transmission is encrypted via TLS; data is stored on AWS cloud servers with encryption at rest; access controls ensure users can only access their own data. We retain data while your account is active and will delete related data within 30 days after account deletion.
Information Sharing
We do not sell your personal information. Data is shared only with: (1) AI service providers (for generating analysis results); (2) Stripe payment processor (for billing); (3) as required by law (such as upon receiving a valid court order).
Your Rights
You have the right to: (1) access personal data we store about you; (2) correct inaccurate information; (3) delete your account and associated data; (4) export your learning data; (5) withdraw consent for data processing. To exercise these rights, please contact support@cramai.net.
Cookies & Analytics
We use essential cookies for authentication and session management. We use Google Analytics (GA4) to collect anonymous usage data (page views, referral sources, device types) to understand overall usage patterns and improve our product. This data is not used to identify individuals. We do not use tracking cookies or third-party advertising cookies. You can manage cookie preferences through your browser settings.
Children's Privacy
Our service is designed for learners of all ages. If you are under 13 years old (or a higher age as required by the laws of your region), please use this service under the supervision of a parent or guardian. We do not knowingly collect personal information from children under 13 without verifiable parental consent. If you believe we have inadvertently collected such information, please contact us so we can delete it.
