We collect information you provide directly, including your name, email address, and profile information when you create an account. We also collect learning progress data, quiz results, and platform usage analytics. If you connect a wallet, we store your public wallet address. We do not store private keys or seed phrases.
We use your information to provide and improve the CryptoU platform, track your learning progress, issue certificates and badges, process payments, send relevant communications (such as course updates and streak reminders), and personalize your experience. We may use aggregated, anonymized data for analytics and platform improvement.
We do not sell your personal information. We may share your information with service providers who help us operate the platform (such as Supabase for database hosting, Stripe for payments, and Resend for email). We may also share information if required by law or to protect our rights and safety.
We implement industry-standard security measures including encryption in transit (HTTPS/TLS), encrypted database storage, row-level security policies, and regular security reviews. However, no method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security.
If you earn CRYPTOU tokens or receive on-chain certificates, transaction data will be recorded on the Base blockchain. Blockchain data is public and immutable — once a transaction is recorded, it cannot be deleted. Your wallet address and transaction history on-chain are publicly visible.
We use essential cookies for authentication and session management. We may use analytics tools to understand how users interact with the platform. You can manage cookie preferences through your browser settings.
You may access, update, or delete your account information at any time through your profile settings. You may request a copy of your data or ask us to delete your account by contacting us. Note that blockchain data cannot be deleted due to the immutable nature of the technology.
CryptoU is not intended for users under the age of 13. We do not knowingly collect information from children under 13. If we become aware that we have collected information from a child under 13, we will take steps to delete it.
We may update this privacy policy from time to time. We will notify you of any material changes by posting the new policy on this page and updating the "Last updated" date.
If you have questions about this privacy policy, please contact us at privacy@cryptou.io.
