忘記咗家長密碼(PIN)點算?

PIN 只存喺你部機入面,我哋冇辦法幫你重設,亦冇任何後門。如果真係入唔到家長端,唯一方法係刪除 app 再重裝 —— 但咁樣會連埋所有學習紀錄一齊清走。所以請將 PIN 記低喺安全嘅地方。

收唔到每日 email 報告?

逐項檢查:

• 小朋友當日至少要做完 1 題,先會有報告。
• email 地址有冇打錯?去「家長端 → 帳戶 → 每日 email 報告」撳「傳送測試報告」即時試一次。
• 部機要有網絡。App 會喺小朋友做完題、退出 app 之後傳。
• 睇下垃圾郵件夾 —— 信件標題以 [MathApp] 開頭。
• 每個小朋友每日只寄一次,唔會重複寄。

小朋友嘅資料存喺邊?換機會唔會跟得走?

全部存喺部機入面,冇雲端同步。換一部新 iPad 嘅話,學習紀錄唔會自動跟過去。如果你用 iCloud / iTunes 做過整機備份再還原,資料就會跟住整機備份返嚟。

點刪除一個小朋友嘅所有資料?

家長端 → 帳戶 → 揀嗰個小朋友 → 刪除。佢嘅答題紀錄、遊戲存檔、設定同草稿會永久剷走(最後一個檔案唔可以刪)。想清走全部,直接喺裝置刪除 MathApp。

點熄匿名診斷?

家長端 → 帳戶 → 「匿名診斷」關掉。關咗即刻停,連本機未傳出嘅紀錄都會清走。詳情見私隱政策第 3.1 節。

題目太淺 / 太深,可以自己調?

可以。家長端 → 改課題,揀返嗰個課題,底部 L1–L5 一撳即時生效;之後 app 會繼續按小朋友表現自動升降級。

做題一定要上網嗎?

唔使。練習全部喺本機行。只有下載題庫更新、傳每日報告同匿名診斷嗰陣先需要網絡。

App 閃退咗 / 有題目出錯 / 答案錯咗,點報?

請經下面嘅聯絡方法話我哋知,盡量寫低:年級、課題名、大約幾時發生、同埋(如果係題目問題)截圖。閃退方面,如果你冇熄匿名診斷,系統通常會自動送一份技術報告過嚟。

I forgot the parent PIN. What now?

The PIN is stored only on your device. We cannot reset it and there is no back door. If you are locked out, the only way in is to delete and reinstall the app — which also erases all learning records. Please keep the PIN somewhere safe.

The daily email report never arrives.

• Your child must have answered at least one question that day.
• Check the address for typos: Parent area → Account → Daily email report → "Send test report".
• The device needs a network connection. The app sends after a practice session, when the app goes to the background.
• Check your spam folder — the subject line starts with [MathApp].
• Only one report per child per day is sent.

Where is my child's data stored? Does it move to a new device?

Everything is on the device, with no cloud sync. Moving to a new iPad will not carry the learning records over by itself. They do come back if you restore that device from a full iCloud or iTunes backup.

How do I delete a child's data?

Parent area → Account → select the child → Delete. Their practice records, game save, settings and scratch images are permanently removed (the last remaining profile cannot be deleted). To remove everything, delete MathApp from the device.

How do I turn off anonymous diagnostics?

Parent area → Account → Anonymous diagnostics → off. It stops immediately and clears anything still queued on the device. See section 3.1 of the privacy policy.

The questions are too easy or too hard. Can I change that?

Yes. Parent area → Change topic, pick the topic, then tap L1–L5 at the bottom; it applies straight away. The app keeps adjusting the level automatically from your child's results afterwards.

Does practising need an internet connection?

No. Practice runs entirely on the device. A connection is only needed to download question-bank updates and to send the daily report and diagnostics.

The app crashed, or a question looks wrong.

Please tell us using the contact details below, including the grade, the topic name, roughly when it happened, and a screenshot if it is a question problem. For crashes, a technical report usually reaches us automatically unless you have switched diagnostics off.
