闪电单词是一款完全离线运行的单词学习应用，我们非常重视你的隐私。本政策说明我们如何（不）处理你的信息。
Flashword is a fully offline vocabulary-learning app. We take your privacy seriously. This policy explains how we do — and do not — handle your information.
1. We collect nothing. Flashword does not collect, upload, or store any personally identifiable information. There is no account system and no server — the app never sends data to any backend.
2. Your data stays on your device. All learning progress, settings, and imported word lists are stored locally and never leave your device. You can clear cached data in Settings → Clear Cache, and deleting the app removes everything.
闪电单词不含任何广告，也不集成任何第三方分析、统计或追踪 SDK，不会与任何第三方共享你的数据。
3. No ads, no third-party SDKs. Flashword contains no advertising and no third-party analytics or tracking SDKs, and shares no data with anyone.
通知（可选）：仅当你主动开启「每日提醒」时才申请，用于在设定时间发送本地学习提醒，不走任何服务器，可随时在系统设置中关闭。
4. Permissions. Notifications are requested only if you turn on the optional “Daily Reminder,” used solely to deliver a local reminder at your chosen time (no server involved). You can disable it anytime in System Settings.
