短信不会上传！短信滤盒在 iPhone 上离线分类和学习，不设账号，不向开发者服务器上传短信、投喂记录或个人模型。系统短信过滤扩展只处理 iOS 交给它的短信；App 无法浏览收件箱。只有你主动点击系统粘贴按钮时，App 才接收要投喂的文本。分类计数由系统 MetricKit 汇总后保存在本机，不上传到我们的服务器。
主动投喂的短信和分类保存在设备上，用于记忆模板和个人学习。你可以在学习记录中修改或删除记录；删除全部投喂会移除个人学习结果。App 不提供开发者云端同步。设备备份是否保留 App 数据，取决于你的系统备份设置。
「本地 AI 自进化功能」是一次性非消耗型内购，无订阅。购买和恢复由 Apple 的 App Store 与 StoreKit 处理。我们不接收你的支付卡资料。购买状态在设备上用于解锁功能，Apple 按其隐私政策处理交易。

Messages and personal learning
Your texts are never uploaded by FilterBox. FilterBox classifies messages and learns offline on your iPhone. There is no account, and messages, submitted examples, and personal models are not uploaded to developer servers. The filtering extension processes only messages provided by iOS. The app cannot browse your inbox and receives teaching text only when you tap the system Paste button. MetricKit classification counts are stored locally and are not uploaded to our servers.
Storage and deletion
Messages you submit and their labels are stored on your device for template matching and personal learning. You can review, relabel, or delete examples in learning history. Deleting all examples also removes personal learning results. We provide no developer-operated cloud sync. System backups may include app data depending on your backup settings.
Purchases
Local AI self-learning is a one-time, non-consumable purchase with no subscription. Apple handles purchases and restores through the App Store and StoreKit. We do not receive payment card details. Purchase status is used on the device to unlock features. Apple processes transactions under its own privacy policy.
