「密密本」隱私權政策
Pocket Book · Privacy Policy
一句話：密密本沒有帳號、沒有伺服器，也不放廣告或追蹤工具，而且完全不連網路。你寫下的每一筆只存在你自己的 iPhone 上，並且加密；我們看不到，也拿不到。
1. 這份政策適用於誰
本政策說明 iOS App「密密本」（英文名稱「Pocket Book」，以下稱「本 App」）如何處理資料。本 App 由 AYC.C. 開發，是一本放在手機裡、會上鎖的密碼本。
2. 我們不收集任何資料
- 本 App 不需要註冊或登入，沒有帳號。
- 本 App 沒有自己的伺服器，也不連網路，不會把任何資料傳給開發者或第三方。
- 本 App 沒有廣告、沒有數據分析或追蹤工具，也沒有使用任何第三方套件。
- 本 App 不會在不同 App 或網站之間追蹤你。
3. 存在你裝置上的資料
你寫進本 App 的內容只存在安裝本 App 的那支 iPhone 上：
- 名稱、分類、建立與修改日期：不加密，讓書本能照注音和標籤排序。
- 帳號、密碼、備註、你自己加的欄位內容，以及換掉的舊密碼：存入前先用 AES-256 加密。
打開這本的鑰匙存在 iPhone 的鑰匙圈裡；另一份用你的 PIN 加密（PBKDF2，六十萬次）。PIN 本身不存在任何地方，我們也沒有任何方法打開你的本子。
刪除本 App，資料就會一起刪除。若你開啟了 iPhone 的 iCloud 備份或用電腦備份，這些資料會依 Apple 的設定包含在你自己的備份裡，仍然是加密的，我們無法存取。你從本 App 匯出的備份檔，會用你另外設定的密碼加密，存放在哪裡由你決定；它只有密密本加上這組密碼能打開，本 App 沒有任何明文匯出。外觀、字型與語言的選擇只存在這支手機上。
4. App 會用到的功能
Face ID 或 Touch ID
只用來打開本子。驗證完全由 iOS 處理，本 App 收不到任何臉部或指紋資料。
剪貼簿
只有在你按「複製」時，才把內容放進剪貼簿；30 秒後自動清掉，而且只限這支手機，不會傳到你的其他裝置。本 App 不讀取剪貼簿。
檔案
只有在你匯出或匯入備份時，才存取你選的那一個檔案。
5. 購買
免費版可以寫 20 筆、用三種本子；完整版是一次買斷的 App 內購買。付款、登入與恢復購買都由 Apple 的 App Store 處理，適用 Apple 的隱私權政策。我們只會收到 Apple 提供的匿名銷售報表，不知道購買者是誰。
6. 你主動寄給我們的資料
「設定 → 關於密密本 → 寫信給作者」會打開你的郵件 App。信件內容完全由你決定，不會自動附上你本子裡的任何內容。我們只用來回覆你和改善 App，不會分享給任何人；你可以隨時來信要求刪除你寄來的信件。
7. TestFlight 測試版
如果你透過 Apple 的 TestFlight 安裝測試版，Apple 會依 TestFlight 的條款提供開發者部分資料，例如受邀時使用的姓名與電子郵件、裝置型號、系統版本、當機紀錄，以及你主動送出的意見回饋與截圖。這些資料只用來修正問題與改善 App。
8. 政策變更
如果本 App 處理資料的方式改變，我們會更新本頁並修改生效日期。

In short: Pocket Book has no accounts, no servers, no ads and no tracking, and it never goes online. Every entry you write stays on your own iPhone, encrypted. We cannot see it and never receive it.
1. Who this policy covers
This policy explains how the iOS app “Pocket Book” (Chinese name 「密密本」, “the app”) handles data. The app is developed by AYC.C. It is a password book that lives in your phone, and locks.
2. We collect no data
- The app has no sign-up, no login and no accounts.
- The app has no server of its own and never goes online. It sends no data to the developer or to anyone else.
- The app contains no ads, no analytics, no tracking tools and no third-party code.
- The app does not track you across other apps or websites.
3. Data kept on your device
What you write in the app is kept only on the iPhone it is installed on:
- Names, categories and the dates entries were made and changed: not encrypted, so the book can sort itself.
- Accounts, passwords, notes, the contents of fields you add, and old passwords you replaced: encrypted with AES-256 before they are saved.
The key that opens the book is kept in the iPhone's keychain; a second copy is locked with your PIN (PBKDF2, 600,000 rounds). The PIN itself is not stored anywhere, and we have no way to open your book.
Deleting the app deletes its data. If you use iCloud Backup or back up to a computer, the data is included in your own backup as Apple's settings decide, still encrypted, and we cannot access it. Backup files you export from the app are encrypted with a separate password you choose, and where you keep them is up to you; only Pocket Book with that password can open one, and the app has no plain-text export of any kind. Your choice of look, typeface and language stays on this phone.
4. Features the app uses
Face ID or Touch ID
Only to open the book. iOS does the checking; the app never receives any face or fingerprint data.
Clipboard
Only when you tap Copy. The copy is cleared after 30 seconds and stays on this phone, never reaching your other devices. The app does not read the clipboard.
Files
Only when you export or import a backup, and only the file you pick.
5. Purchases
The free version holds 20 entries and three of the looks; the full version is a one-time in-app purchase. Payment, signing in and restoring purchases are handled by Apple's App Store under Apple's privacy policy. We receive only the anonymous sales reports Apple provides and do not know who bought the app.
6. Information you send us
“Settings → About Pocket Book → Write to the author” opens your mail app. What you write is entirely up to you; nothing from your book is attached. We use it only to reply to you and improve the app, and never share it. You can ask us at any time to delete messages you sent.
7. TestFlight beta
If you install a beta through Apple's TestFlight, Apple shares some data with the developer under TestFlight's terms, such as the name and email used for the invitation, device model, OS version, crash logs, and any feedback and screenshots you choose to send. We use this only to fix problems and improve the app.
8. Changes to this policy
If the way the app handles data changes, we will update this page and its effective date.
