SmsLLM filters SMS messages from unknown senders on iOS. This policy explains exactly what data is and is not handled. The short version: your messages are classified on your device and are never uploaded or stored by us.
When iOS hands a message from an unknown sender to SmsLLM, it is evaluated entirely on your iPhone by an offline rule engine. The message text is processed transiently to decide where it belongs (Junk / Promotion / Transaction) and is then discarded. We never receive, transmit, or store the contents of messages that are filtered. Messages from your contacts and iMessage are never seen by the app — iOS does not pass them to message filters.
If you choose to report a message from the Report screen, the text you paste (and an optional sender you type) is sent to our server so we can improve our detection rules. This is the only situation in which message content leaves your device, and it only happens when you actively tap to submit. Reports are not linked to your identity and are not used to track you. Please avoid including personal information in the message you report.
Our detection rules are generated on our servers using AI that studies scam patterns from user reports and from publicly available scam intelligence. The AI never reads your private messages — it works from reported samples and public sources, and the resulting rules are delivered to your device as updates.
Subscriptions are processed by Apple through the App Store. We do not receive or store your payment information. Your subscription funds the ongoing rule generation and daily updates.
Filtered messages are never stored. Reported messages are retained only as long as needed to improve rules and are not associated with you.
SmsLLM is not directed at children under 13 and does not knowingly collect data from them.
If this policy changes, we will update this page and revise the date above.

SmsLLM 在 iOS 上过滤来自陌生号码的短信。本政策说明我们处理与不处理哪些数据。 一句话：你的短信在你的设备本地完成判定，我们从不上传、从不存储。
当 iOS 把一条陌生号码的短信交给 SmsLLM 时，它完全在你的 iPhone 本地、由离线规则 引擎判定。短信内容仅被短暂处理以决定归类（垃圾箱／推广／交易），随即丢弃。我们绝不 接收、传输或存储被过滤短信的内容。通讯录联系人和 iMessage 的短信不会被本应用看到 —— iOS 不会把它们交给短信过滤器。
如果你在「举报」页面主动举报一条短信，你粘贴的文字（以及可选填写的发件人）会被 发送到我们的服务器，用于改进识别规则。这是短信内容唯一会离开你设备的情形，且仅在你 主动点击提交时发生。举报内容不与你的身份关联，也不用于追踪你。请避免在举报内容中 包含个人信息。
我们的识别规则在服务器上由 AI 生成：AI 从用户举报和公开的诈骗情报中研究诈骗手法。 AI 从不读取你的私人短信 —— 它基于举报样本和公开来源工作，生成的规则作为更新下发到 你的设备。
订阅由 Apple 通过 App Store 处理。我们不接收也不存储你的支付信息。你的订阅用于 支持规则的持续生成与每日更新。
被过滤的短信从不存储。举报的短信仅保留至改进规则所需的时长，且不与你关联。
SmsLLM 并非面向 13 岁以下儿童，也不会有意收集他们的数据。
本政策如有变更，我们将更新本页面并修订上方日期。
