Privacy Policy

What we collect

• Without an account: a randomly generated device identifier stored in your browser, your study activity (which words you review and how you grade them), and standard technical data such as a hashed IP address used for rate limiting and abuse prevention.
• With an account: your email address, an optional display name, and a securely hashed password. If you sign in with Google, we receive your email and name from Google; we never see your Google password.
• If you subscribe: payments are processed by Stripe. We store a subscription reference and license status. We never see or store your card number.

What we use it for

• Saving your study progress and syncing it across your devices when you sign in.
• Operating the service: spaced-repetition scheduling, audio generation, translations, and abuse prevention.
• Sending transactional email you request, such as password reset links. We do not send marketing email.

What we do not do

• We do not sell or share your personal data with advertisers or data brokers.
• We do not use third-party advertising or cross-app tracking.
• We do not collect precise location, contacts, photos, or microphone audio beyond optional in-app speech practice, which is processed to check your pronunciation and not retained.

Third parties we rely on

• Stripe for payment processing.
• Google for optional sign-in and for text-to-speech audio generation.
• Resend for transactional email delivery.
• OpenAI for generating example sentences and translations of dictionary content; your study text may be sent for that purpose, never your account details.

Retention and deletion

Your data is kept while your account is active. You can permanently delete your account and all study data at any time, either from Settings in the app or at flashcards.alexsears.org/delete-account.html. Deletion is immediate and irreversible. Anonymous device data can be cleared by clearing your browser storage.

Children

The service is a general-audience language-learning tool and is not directed at children under 13.
