Introduction
DeeperMemo ('we', 'us', or 'our') operates the DeeperMemo language learning platform and its associated subsites. This Privacy Policy explains what information we collect, how we use it, and what choices you have. By using DeeperMemo, you agree to the practices described in this policy.
Information we collect
We collect information you provide directly, including account credentials (email address and password), learning activity (articles read, words marked, search queries, review history), subscription and payment information, and messages you send to our support team. We also automatically collect device information such as IP address, browser type, operating system, and usage patterns through standard logging and analytics tools.
How we use information
We use collected information to: operate and improve the learning experience; personalize spaced review and search results based on your reading history; process subscriptions and payments; maintain service security and prevent abuse; communicate with you about your account and support requests; and analyze usage patterns to improve product features.
Cookies and local storage
DeeperMemo uses cookies and browser local storage to maintain your login session, remember your language and subsite preferences, and support basic analytics. You can control cookies through your browser settings, but disabling them may affect your ability to use the service.
Third-party services
We may use third-party services for payment processing, email delivery, and basic analytics. These services have their own privacy policies and are contractually limited to using your data only for the services they provide to us. We do not sell your personal information to third parties.
Data security
We implement industry-standard security measures to protect your information, including encrypted connections (HTTPS), secure password storage, and access controls. However, no internet-based service can guarantee absolute security.
Data retention
Your learning records, reading history, and marked words are retained while your account is active, as they are essential to the core learning experience. If you delete your account, we will remove your personal data within 30 days, except where retention is required for legal, security, or billing purposes.
Your rights
You have the right to access, correct, or delete your personal information. You can export your learning data, update your account details, or request account deletion at any time by contacting our support team. Users in the EU and other jurisdictions with data protection laws may have additional rights under applicable regulations.
Children's privacy
DeeperMemo is not intended for children under 13. We do not knowingly collect personal information from children under 13. If we learn that we have collected such information, we will delete it promptly.
Changes to this policy
We may update this Privacy Policy from time to time. When we make material changes, we will notify you through the service or by email. Your continued use of DeeperMemo after changes take effect constitutes acceptance of the updated policy.
