🛡 Core Commitment: EnglishSpellPad is a 100% offline English learning app. All your learning data is stored locally on your device. We do not upload, share, or use your data for advertising.

1. Data We Collect

EnglishSpellPad stores the following learning data only on your iPad/iPhone device:

Data TypePurposeStorage

Game progress (score, combo, mountains)Game state restorationApp sandbox /Documents/
Achievement unlocksAchievement wall displayApp sandbox /Documents/
User preferencesLevel, sound, font sizeApp sandbox /Documents/
Daily streak (修仙 realm progress)Realm progressionApp sandbox /Documents/

We do NOT collect: name, email (unless you contact us), location, device identifiers, IP addresses, cookies, or advertising identifiers (IDFA).

2. Third-Party SDKs and Network Requests

This app does not integrate any third-party analytics, advertising, or tracking SDKs.

The app makes network requests in these situations:

  • None — the app does not make any network requests during runtime.

All content (6,379 English words, 6 spelling rules, 48 IPA phonemes, 11 achievements) is bundled in the app and runs fully offline.

3. How We Use Your Data

  • All data is used only on your own device to display learning progress and personalize content.
  • We cannot access your learning data (because it's on your device).
  • We do not sell, rent, or share any of your data with third parties.

4. Audio Permissions

The app uses iOS AVSpeechSynthesizer to read English words and example sentences aloud (for pronunciation learning).

This feature does not require user permission and does not access the microphone or record any audio.

5. Children's Privacy (COPPA)

This app is suitable for all ages and is not specifically targeted at children under 13. We do not knowingly collect personal information from children.

If you are a parent and discover your child has used the app without your knowledge, please contact us at the email below for assistance.

6. Your Rights and Data Control

Since all data is stored locally on your device, you have full control over your data:

  • View data: Open app → Tools → "Word Stats" sheet
  • Delete learning data: Uninstall the app (removes sandbox) or in-app reset (future feature)
  • Export data: Contact us at the email below
  • Questions: Contact us anytime at the email below

7. Data Retention and Deletion

  • App data is retained until you uninstall the app or manually reset.
  • Uninstalling the app = iOS automatically clears the sandbox — all local data is immediately deleted.
  • We have no server-side storage, so we cannot retain any user data.

8. Security Measures

  • iOS sandbox isolates app data — other apps cannot access it.
  • All data is stored locally — no network transmission = no man-in-the-middle risk.
  • No login system, no cloud sync — no account leak risk.

9. Policy Updates

This policy may be revised as the app updates. Material changes will be announced via in-app notifications.

Current version: v1.0 · Effective: 2026-06-28
