常見問題
忘了 PIN 怎麼辦？
如果開了 Face ID（或 Touch ID），還是能用它打開本子。更改 PIN 要先輸入舊的 PIN，所以請趁還能打開時到「設定 → 匯出備份」做一份備份，再刪除 App 重新安裝，設定新的 PIN，然後用備份密碼匯入備份。
如果不能用 Face ID，這本就打不開了：密密本沒有後門，我們也打不開。若你之前匯出過備份檔，可以照上面的方法重新安裝後匯入。
換新手機要怎麼搬？
兩種方法都可以：
- 用 iCloud 備份或電腦備份把整支手機還原到新手機，打開密密本，輸入原本的 PIN。
- 在舊手機「設定 → 匯出備份」，把 .pocketbook 檔案傳到新手機，再到「設定 → 匯入備份」，輸入備份密碼。
備份檔要用什麼打開？
只有密密本能打開。備份檔裡沒有任何明文，整本內容用你匯出時設定的密碼加密（PBKDF2 六十萬次推導金鑰，AES-GCM 加密），用文字編輯器打開只會看到亂碼。要讀它，在另一支手機裝密密本 → 設定 → 匯入備份 → 選這個檔 → 輸入當時的備份密碼。密密本沒有、也不會有明文匯出；備份密碼忘了，這份備份就打不開了。
免費版和完整版差在哪裡？
免費版可以寫 20 筆、用三種本子（橫線簿、文具店、歐洲帳簿），其他功能完全一樣。完整版不限筆數、十一種本子都能用，一次買斷，不訂閱。寫滿 20 筆之後，已經寫的照樣能看、能改、能複製、能匯出；匯入備份也不受限制，已經換上的本子也不會收回。
換手機或重新安裝後，完整版不見了？
到「設定 → 關於密密本」按「恢復購買」，並確認用的是當初購買的同一個 Apple ID。
密密本會自動填入密碼或同步到其他裝置嗎？
不會。密密本刻意只做一本本子：不連網路、不自動填入、不同步。要搬資料請用加密的備份檔。
我的密碼安全嗎？
帳號、密碼、備註存入前都用 AES-256 加密，打開本子要 PIN 或 Face ID。複製的密碼 30 秒後從剪貼簿消失；切到別的 App 時畫面會蓋上封面。詳細請看隱私權政策。

Questions
I forgot my PIN.
If Face ID (or Touch ID) is on, you can still open the book with it. Changing the PIN asks for the old one first, so while the book is open, make a backup with “Settings → Export backup”, then delete and reinstall the app, set a new PIN, and import the backup with its backup password.
If you can't use Face ID, the book cannot be opened: Pocket Book has no back door, and we can't open it either. If you exported a backup earlier, reinstall and import it as above.
How do I move to a new phone?
Either way works:
- Restore the whole phone from an iCloud or computer backup, open Pocket Book and enter your PIN.
- On the old phone use “Settings → Export backup”, move the .pocketbook file to the new phone, then use “Settings → Import backup” and enter the backup password.
What opens a backup file?
Only Pocket Book. A backup holds no plain text: the whole book is encrypted with the password you set when exporting (a PBKDF2 key, 600,000 rounds, AES-GCM), and a text editor shows only noise. To read it, install Pocket Book on the other phone → Settings → Import backup → pick the file → enter that backup password. There is no plain-text export and there will not be one; a forgotten backup password means that backup stays closed.
What does the full version add?
The free version holds 20 entries and three of the looks (Lined, Stationery, Cash Book), and is otherwise the same. The full version has no limit and every look; you pay once, with no subscription. Once the free 20 are written, you can still read, edit, copy and export them all, importing a backup is never limited, and a look already on the book stays on.
The full version is gone after a new phone or a reinstall.
Go to “Settings → About Pocket Book” and tap “Restore purchase”, signed in with the Apple ID you bought it with.
Does Pocket Book fill in passwords or sync?
No. Pocket Book is deliberately just a book: it never goes online, never fills passwords in and never syncs. To move your entries, use the encrypted backup file.
Are my passwords safe?
Accounts, passwords and notes are encrypted with AES-256 before they are saved, and opening the book takes your PIN or Face ID. A copied password leaves the clipboard after 30 seconds, and the cover closes over the book when you switch apps. See the privacy policy for details.
