Quiz Notebook Pro for iPad
Privacy and data handling

Effective October 7, 2026. Operator and privacy contact: YSEEDU, Hyunho Son.

This notice covers the iPad app listed as Quiz Notebook Tablet. Phone, Mac, Windows and web products have separate licenses and processing arrangements.

Your study materials stay on this iPad by default. Account sign-in, selected-material synchronization and external AI requests are optional. Local study uses your Apple trial or purchase entitlement without requiring an app account or AI. We do not sell personal data or use advertising tracking.

1. Local materials

Decks, images, handwriting, notes and study records are stored locally. You choose files to import, export or share. Back up Simple Notes and AI work separately from deck/study backups before removing the app. Device backups and cloud locations you choose follow their providers’ policies.

2. Optional account and synchronization

Email sign-in processes the email you enter, random account identifiers and authentication/session/expiry records. A sign-in link is sent only when requested. The session is kept in the device’s secure storage.

Sync is off by default. When enabled, selected personal cards, edits, images and study positions, along with account/revision identifiers and timestamps, are sent over HTTPS and stored encrypted on Azure in Korea Central, South Korea. This is not end-to-end encryption. Whole original PDFs, unselected sets, all Simple Notes or AI work are not automatically synchronized. Official paid-deck content and store rights are excluded from this personal-material store.

Turning sync off stops new transfers; server copies remain until account deletion. Deleting a whole set does not delete it on other devices. Card/photo changes within a connected set do sync. Concurrent revisions are preserved for your review.

3. Your AI or API

For manual prompt transfer, the external service’s policies apply when you send material there. For in-app API requests, you review and consent to the request and use your own OpenAI or Anthropic key. This iPad route sends HTTPS requests directly to the chosen provider, not through the YSEEDU account server. The key is used in memory for the request and is not saved in this app’s persistent storage. Other materials are not read or sent automatically.

OpenAI response storage is disabled, but no-retention by the provider is not guaranteed. Providers may process/retain account and request information abroad for their service, safety and legal obligations. Review the OpenAI and Anthropic policies. Their fees and limits apply to your account and are not included in the app license. Avoid sensitive personal information. Review and adopt AI results before saving them into a deck.

4. Apple trial and purchases

The seven-day trial and lifetime access use Apple StoreKit. Signed transactions and entitlements are verified on the device. We do not receive payment-card details or Apple passwords. The trial does not automatically charge or renew. This iPad app does not use a RevenueCat SDK path or sell additional content decks. Apple handles payments and its transaction records under its privacy policy.

5. Providers, retention and deletion

Microsoft Azure in Korea Central hosts the shared account and explicitly enabled sync materials. Resend in the United States handles requested login emails, one-time links and delivery metadata; its published standard retention is 30 days for email/logs plus up to seven additional days for provider backups. See Resend’s policy. The Quiz Notebook/Wrongnote account is shared; product entitlements remain separate.

Account and sync data remain while needed to maintain the account and provide the service. Login links last 15 minutes and sessions up to 30 days; expired records follow the service’s cleanup policy. Choose Delete account in account management to remove the shared account, sessions, server purchase links and sync material, including registered recovery backups within seven days. Required legal records and limited anti-abuse verification records follow the shared-account retention notice; email plaintext and learning materials are excluded from anti-abuse records.

Deleting an account affects shared-account access on other devices. It does not delete local learning files, refund purchases or cancel other products’ store subscriptions. You can request access, correction, deletion or restriction in account management or through the contact below. Avoid including unnecessary personal or student information.
