InputBull 隱私權政策
InputBull 是陪你潤飾文字的離線 AI Copilot（副駕駛）。這份政策說明 InputBull 會處理哪些資料、怎麼處理。
你輸入的文字
- 你用 InputBull 潤飾或翻譯的文字，只會在你的手機上由本機 AI 模型處理，不會上傳到任何伺服器，也不會傳給開發者或任何第三方。
- 長按選取外掛：你在其他 App 選取文字並點「潤飾」或「翻英」時，Android 會把選取的文字交給 InputBull 處理；按「取代原文」時，結果會交回那個 App。
- 剪貼簿：InputBull 不會讀取你的剪貼簿。只有在你按「複製」時，才會把潤飾或翻譯的結果寫入剪貼簿。
- 同步輸入框（選用，預設關閉）：這個功能使用 Android 無障礙服務（AccessibilityService API）。只有在你看過 App 內的說明並同意、再到系統設定開啟後才會運作。開啟期間，它會讀取你目前正在輸入的文字框內容，帶入懸浮球，並在你按「取代原文」時把結果寫回那個輸入框。它不讀取密碼欄位，也不讀取其他畫面內容。讀到的文字只在手機上處理，不會儲存，也不會傳出手機。你隨時可以在 InputBull 設定或系統的無障礙設定裡關閉。
- 你設定的角色、語氣和自訂提示詞只存在手機上。
網路連線與模型下載
InputBull 只會為了下載 AI 模型檔連上網路，你輸入的文字不會經過網路。
- 下載前，App 會透過 Google Play Integrity API 確認 App 是從 Google Play 安裝的正版、且在正常的裝置上執行。這項檢查由 Google 處理，適用 Google 隱私權政策。
- 模型檔放在 Cloudflare（R2 儲存空間與 Workers）上。下載時，伺服器會收到連線必需的技術資訊（IP 位址、Play Integrity 驗證結果），只用來產生有時效的下載連結並傳送檔案。我們不記錄這些資訊，也不會用來辨識你的身分。Cloudflare 對網路流量的處理適用 Cloudflare 隱私權政策。
- 回報 AI 內容：當你在結果框主動點按「回報 AI 內容」時，App 只會傳送回報原因（冒犯或不當、結果不正確、其他）、功能模式與模型版本，不會傳送你輸入的文字或 AI 產生的文字。
我們不收集的資料
InputBull 沒有帳號系統、分析工具或當機回報 SDK，不會收集你的姓名、聯絡人、位置、裝置識別碼或使用紀錄，也不會把任何資料賣給或分享給第三方。
資料保存與刪除
InputBull 的所有資料（設定、模型檔）都只存在你的手機上。在系統設定清除 InputBull 的儲存空間，或解除安裝 App，就會全部刪除。Android 的雲端備份只會備份設定，不包含模型檔。
兒童
InputBull 不是為 13 歲以下兒童設計的，也不會刻意收集兒童的資料。
政策變更
政策有變更時，我們會更新這個頁面和上方的生效日期。

InputBull Privacy Policy
InputBull is a copilot for you to refine your text, running offline on your phone. This policy explains what data InputBull handles and how.
Text you write
- Text you polish or translate with InputBull is processed only on your phone by an on-device AI model. It is never uploaded to any server and never sent to the developer or any third party.
- Text selection menu: when you select text in another app and tap "Polish" or "Translate", Android passes the selected text to InputBull; tapping "Replace" hands the result back to that app.
- Clipboard: InputBull never reads your clipboard. It writes a result to the clipboard only when you tap "Copy".
- Input sync (optional, off by default): this feature uses the Android AccessibilityService API. It only runs after you accept the in-app disclosure and turn it on in system settings. While on, it reads the text field you are currently typing in, passes it to the floating button, and writes the result back into that field when you tap "Replace". It never reads password fields or other screen content. The text is processed on the device only and is not stored or transmitted. You can turn it off at any time in InputBull settings or the system accessibility settings.
- Your roles, tones and custom prompts are stored only on your phone.
Network access and model download
InputBull connects to the internet only to download its AI model files. The text you write never goes over the network.
- Before downloading, the app uses the Google Play Integrity API to confirm it is a genuine copy installed from Google Play on a genuine device. Google handles this check under the Google Privacy Policy.
- The model files are hosted on Cloudflare (R2 storage and Workers). The server receives the technical information needed for the connection (IP address and the Play Integrity verdict), used only to create a time-limited download link and deliver the files. We do not log this information or use it to identify you. Cloudflare's handling of network traffic is covered by the Cloudflare Privacy Policy.
- Reporting AI content: when you tap the report flag in the result box, the app sends only the selected reason (offensive, inaccurate, or other), the task mode, and the model version—never your input text or the generated text.
Data we do not collect
InputBull has no accounts, analytics or crash-reporting SDKs. It does not collect your name, contacts, location, device identifiers or usage history, and it never sells or shares data with third parties.
Retention and deletion
All InputBull data (settings and model files) stays on your phone. Clearing InputBull's storage in system settings, or uninstalling the app, deletes all of it. Android cloud backup includes your settings only, not the model files.
Children
InputBull is not designed for children under 13 and does not knowingly collect children's data.
Changes
If this policy changes, we will update this page and the effective date above.
