Library Smash does not collect any data.
That is the whole policy, and the rest of this page only explains why it can be that short.
The entire game — every model, texture, sound and line of text — is contained inside the app itself. It is not downloaded and nothing is uploaded. The app works exactly the same with the device in Aeroplane Mode, and you are welcome to check.
Your progress is saved on your own device, in the app's own storage: which levels you have cleared, how many stars each earned, your best scores, and which jobs the game has already taught you so it stops explaining them. None of it leaves the device. Deleting the app deletes all of it.
If you choose to use the leaderboards, scores are submitted to Apple's Game Center under your own Game Center identity. That is a service provided by Apple, governed by Apple's privacy policy, and it is entirely optional — the game is fully playable without it and never asks you to sign in.
We do not receive, see or store your Game Center name, your scores or any other information about you.
This app is intended for use by secondary school students and their teachers. It collects nothing, so there is nothing to collect from a child. There is no advertising, no analytics, no third-party software development kit of any kind, no in-app purchase and no way to contact another person through the app.

《圖書館大作戰》唔收集任何資料。
呢句就係成份私隱政策。下面淨係解釋點解可以咁短。
成個遊戲 —— 每一個模型、貼圖、音效同每一句文字 —— 都喺 app 本身入面。唔會 下載，亦冇任何嘢會上載。將部機較做飛行模式，個遊戲行得一模一樣，歡迎你試。
你嘅進度存喺你自己部機、喺 app 自己嗰個儲存空間入面：邊幾關過咗、每關攞咗 幾多粒星、最高分，同埋遊戲已經教過你邊幾樣工作（教夠三次就唔再解釋）。全部 都唔會離開部機。刪咗個 app，呢啲亦一齊冇晒。
如果你揀用排行榜，分數會用你自己嘅 Game Center 身份交去 Apple 嘅 Game Center。嗰個係 Apple 提供嘅服務，受 Apple 自己嘅私隱政策規管，而且完全係 自願 —— 唔登入一樣玩到成個遊戲，個 app 亦唔會叫你登入。
我哋收唔到、睇唔到、亦唔會儲你嘅 Game Center 名、分數或者任何關於你嘅資料。
呢個 app 係畀中學生同老師用嘅。佢乜都唔收集，所以亦冇嘢可以喺一個小朋友身上 收集。冇廣告、冇分析工具、冇任何第三方 SDK、冇任何應用程式內購買，亦冇任何 途徑可以喺 app 入面聯絡到另一個人。
