01概述
NoteOwl（中文名「书记官」，下称「本应用」）是一款在 iPhone、iPad 和 Mac 上运行的听课/会议智能笔记应用。本应用的隐私承诺是架构层面的，不是条款层面的：录音与照片在应用内不存在任何上传通道。
一句话版本：我们不收集你的任何数据。没有账号系统，没有分析统计，没有广告，没有追踪。你的录音、照片、转写文字和笔记全部保存在你自己的设备上。
02我们收集哪些信息
不收集。本应用：
- 不要求也不提供注册账号；
- 不内嵌任何分析、统计或广告 SDK；
- 不向开发者的服务器发送任何数据——我们没有收集用户数据的服务器；
- App 的 Apple 隐私清单（PrivacyInfo.xcprivacy）声明的数据收集类型为「无」、追踪为「无」。
03数据如何在你的设备上处理
以下处理全部在你的设备端完成，断网可用，内容不离开设备：
- 录音：通过麦克风录制课堂/会议音频，仅保存在本应用的本地存储中。
- 转写：使用系统端上语音识别（Apple SpeechAnalyzer）将录音转为文字。
- 笔记整理：使用端上智能（Apple Intelligence 端上模型，或你下载到本机的开源模型）把转写整理成结构化笔记。
- 拍照 OCR：用相机拍摄的 PPT/白板照片仅存本地，文字识别（Apple Vision）在端上完成。
04云端增强（可选功能，默认关闭）
「云端增强」（深度总结/跨课归纳）是本应用唯一可能产生对外网络传输的功能，并受以下约束：
- 默认关闭，且需要你自行配置所选服务商的 API Key 才能使用；
- 仅在你每次主动点击并在发送前预览确认后才发送；
- 只发送你确认过的文本（笔记与转写节选）——录音与照片在任何情况下都不会被发送；
- 文本直接发送到你选定的服务商：Anthropic Claude、OpenAI、Google Gemini，或你自建的 Ollama 服务。数据由该服务商按其自己的隐私政策处理，我们不经手、不留存、看不到；
- 若你使用自建 Ollama（本机或局域网），数据不出你自己的网络；
- 你的 API Key 仅保存在设备的系统钥匙串（Keychain）中，仅用于直连你选定的服务商。
05系统权限
- 麦克风：录制课堂/会议音频，录音仅存本机。
- 语音识别：端上转写，内容不上传。
- 相机：拍摄 PPT/白板并端上 OCR，照片仅存本机。
- 本地网络（仅在需要时）：当你把云端增强的服务地址指向局域网内自建服务（如 Ollama）时，系统会请求本地网络权限。
06内购与订阅
Pro 订阅/买断通过 Apple App Store 完成。支付由 Apple 处理，我们不会收到你的姓名、地址或银行卡信息；购买凭据在设备本地通过 StoreKit 校验，无需账号。相关数据处理适用 Apple 的隐私政策。
07数据保留、备份与删除
- 你的全部数据只存在于你的设备上。在应用内删除某个课程，或删除本应用，数据即被删除；我们无法访问、也无法替你恢复。
- 你的设备备份（iCloud 备份或电脑备份）可能包含本应用的数据；该备份由 Apple 的备份机制按你的设备设置处理，不属于本应用的上传行为。
08儿童隐私
本应用不收集任何人的个人信息，因此也不收集儿童的个人信息。

01Overview
NoteOwl ("the App") is an AI note-taking app for lectures and meetings on iPhone, iPad and Mac. Our privacy commitment is architectural, not contractual: the App contains no upload path for your recordings or photos.
The one-sentence version: we collect none of your data. No accounts, no analytics, no ads, no tracking. Your recordings, photos, transcripts and notes all stay on your own device.
02Information We Collect
None. The App:
- has no account system and never asks you to sign up;
- embeds no analytics, telemetry or advertising SDKs;
- sends no data to the developer — we operate no servers that receive user data;
- declares "no data collected" and "no tracking" in its Apple privacy manifest (PrivacyInfo.xcprivacy).
03How Data Is Processed on Your Device
All of the following happens entirely on-device, works offline, and never leaves your device:
- Recording: lecture/meeting audio captured via the microphone is stored only in the App's local storage.
- Transcription: on-device speech recognition (Apple SpeechAnalyzer) turns recordings into text.
- Note organization: on-device intelligence (Apple Intelligence on-device models, or an open-source model you download to your device) turns transcripts into structured notes.
- Photo OCR: photos of slides/whiteboards are stored locally; text recognition (Apple Vision) runs on-device.
04Cloud Enhancement (Optional, Off by Default)
"Cloud Enhancement" (deep summary / cross-session synthesis) is the only feature of the App that can send anything over the network, and it is constrained as follows:
- it is off by default, and requires you to configure your own API key for a provider of your choice;
- it sends only when you explicitly tap it each time and confirm a preview of exactly what will be sent;
- it sends only the text you approved (notes and transcript excerpts) — recordings and photos are never sent, under any circumstances;
- the text goes directly to the provider you selected: Anthropic Claude, OpenAI, Google Gemini, or your own self-hosted Ollama server. That provider processes it under its own privacy policy; we never receive, store or see it;
- if you use self-hosted Ollama (on your machine or LAN), the data never leaves your own network;
- your API keys are stored only in the device's system Keychain and are used only to connect directly to the provider you chose.
05System Permissions
- Microphone: to record lectures/meetings; audio stays on your device.
- Speech recognition: on-device transcription; nothing is uploaded.
- Camera: to photograph slides/whiteboards for on-device OCR; photos stay on your device.
- Local network (only when needed): requested if you point Cloud Enhancement at a self-hosted service on your LAN (e.g. Ollama).
06In-App Purchases and Subscriptions
Pro subscriptions/purchases are handled by the Apple App Store. Payment is processed by Apple; we never receive your name, address or payment details. Entitlements are verified locally via StoreKit, with no account required. Apple's Privacy Policy applies.
07Data Retention, Backup and Deletion
- All your data exists only on your device. Deleting a session in the App, or deleting the App, deletes the data; we cannot access it and cannot recover it for you.
- Your own device backups (iCloud Backup or computer backups) may include the App's data; those backups are handled by Apple's backup mechanisms under your device settings and are not an upload by the App.
08Children's Privacy
The App collects no personal information from anyone, including children.
09The Website (noteowl.io)
The website is static: no cookies, no analytics, no ads. Browser localStorage is used only to remember your language choice and never leaves your browser. Fonts are loaded via Google Fonts, so your browser makes a request to Google's font servers; Google's Privacy Policy applies to that request.
10Changes to This Policy
If this policy changes materially, we will update this page and its effective date, and notify you in the App for significant changes.
