私隱政策
最後更新：2026-11-02
Kaojai（「我們」）提供 Kaojai 秒懂 App 同 kaojai.live 網站。本政策說明我們收集甚麼資料、如何使用、交由哪些服務處理，以及你可以怎樣選擇。
我們收集的資料
- 帳戶：你用 Google 登入時的電郵地址和帳戶 ID。
- 裝置：由手機裝置 ID 計出的單向雜湊值，用來令每部手機只有一份免費額度；我們看不到原本的裝置 ID。
- 用量：每月翻譯了多少分鐘、AI 用量和成本，用來計算你的方案額度。
- 付款：由 Stripe 處理。我們只收到訂閱狀態和 Stripe 客戶編號，不會收到你的卡號。
- 改善詞庫包（可關閉）：當你標記「譯錯」或修正一句時，該句和前兩句的原文與譯文會送到我們，用來改善詞庫包，保留 90 日。可在 App「設定 → 協助改善詞庫包」關閉。
聲音和文字
翻譯時，App 把聲音即時串流到我們委託的語音辨識服務，辨識出的文字再送到我們委託的 AI 翻譯服務。我們不會儲存你的聲音或翻譯內容（上面「改善詞庫包」所述的除外）。翻譯紀錄、錄影和匯出的檔案只會存在你的手機上。
處理資料的服務
我們使用以下類別的服務供應商：雲端伺服器及資料庫、帳戶登入（Google）、語音辨識、AI 翻譯、付款處理（Stripe）。它們只按我們的指示、為提供本服務而處理資料，並受保密及資料保護義務約束。
我們不會做的事
我們不會出售你的資料，不會用來賣廣告，也不會用你的聲音或內容訓練我們的模型。
保存和刪除
帳戶和用量資料在你使用期間保存。想刪除帳戶和所有相關資料，請電郵 support@kaojai.live，我們會在 30 日內處理。手機上的紀錄可在 App 內刪除，或解除安裝 App。

Privacy policy
Last updated: 2026-11-02
Kaojai ("we") runs the Kaojai app and the kaojai.live website. This policy explains what we collect, how we use it, who processes it for us, and your choices.
What we collect
- Account: your email address and account ID when you sign in with Google.
- Device: a one-way hash of your phone's device ID, so each phone gets one free allowance; we never see the original ID.
- Usage: minutes translated each month and AI usage and cost, to work out what's left on your plan.
- Payments: handled by Stripe. We only receive your subscription status and Stripe customer ID, never your card number.
- Improving packs (can be turned off): when you flag a line as wrong or correct it, that line and the two before it (original and translation) are sent to us to improve vocabulary packs, and kept for 90 days. Turn it off in the app under Settings → Help improve vocabulary packs.
Audio and text
While translating, the app streams audio to a speech recognition service we use, and the recognised text goes to an AI translation service we use. We don't store your audio or translations (except as described under "Improving packs"). Transcripts, recordings and exports stay on your phone.
Services that process data for us
We use service providers in these categories: cloud servers and database, sign-in (Google), speech recognition, AI translation, and payments (Stripe). They process data only on our instructions, to provide this service, and are bound by confidentiality and data-protection obligations.
What we don't do
We don't sell your data, use it for advertising, or train our models on your audio or content.
Keeping and deleting data
Account and usage data is kept while you use Kaojai. To delete your account and all related data, email support@kaojai.live; we'll do it within 30 days. Transcripts on your phone can be deleted in the app, or by uninstalling it.
Children
Kaojai is not meant for children under 13.
Changes
If this policy changes in an important way, we'll tell you in the app or on this site.
