本 App 不收集任何個人資料
This App collects zero personal data

Dualvideo(「本 App」)由 Dylvex 開發與發行,本政策說明本 App 如何處理您的資料。

🔒 本 App 不收集、不儲存、不傳送任何個人資料至外部伺服器。所有影片處理皆在您的裝置本機完成。本 App 亦不使用任何追蹤技術,無需取得 Apple 的 App Tracking Transparency(ATT)授權。

Dualvideo (the "App") is developed and published by Dylvex. This policy explains how the App handles your information.

🔒 The App does not collect, store, or transmit any personal data to external servers. All video processing happens locally on your device. The App does not use any tracking technologies and does not request Apple's App Tracking Transparency (ATT) authorization.

我們收集的個人資料 Personal Information We Collect

無。具體而言,本 App 不會收集、儲存或傳送以下任何資料:

  • 您的姓名、Email、電話號碼
  • 裝置 ID、廣告識別碼(IDFA)
  • 位置資訊(GPS 或網路位置)
  • 影片或音訊內容
  • 使用行為分析、Crash log 或遙測資料
  • 任何形式的個人識別資訊
  • 瀏覽記錄或搜尋紀錄
  • 購買記錄或財務資訊
本 App 不與任何第三方分享使用者資料,亦無資料保留期限的問題——因為我們從未儲存任何資料。

None. Specifically, the App does not collect, store, or transmit:

  • Your name, email address, or phone number
  • Device identifiers (including IDFA)
  • Location data (GPS or network-based)
  • Video or audio content
  • Usage analytics, crash logs, or telemetry
  • Any form of personally identifiable information
  • Browsing or search history
  • Purchase history or financial information
The App does not share any user data with third parties. There is no data retention period because we never store any data in the first place.

第三方服務與 SDK Third-Party Services & SDKs

本 App 不整合任何第三方分析、廣告、追蹤、崩潰回報或社群登入 SDK。所有功能均使用 Apple 原生框架(AVFoundation、Photos)在本機實作。

本 App 不使用 Apple 的廣告追蹤框架(ATT),不會要求向您顯示追蹤授權彈窗。

當您使用「分享」功能時,將透過 iOS 系統內建的分享面板(UIActivityViewController),由您自行選擇要分享至哪個 App(例如:Instagram、訊息、AirDrop)。一旦離開本 App,後續流程受該 App 自己的隱私權政策規範,本 App 不對該過程負責。

The App does not integrate any third-party analytics, advertising, tracking, crash-reporting, or social-login SDKs. All features are implemented locally using Apple's native frameworks (AVFoundation, Photos).

The App does not use Apple's App Tracking Transparency (ATT) framework and will never present a tracking-authorization prompt to you.

When you use the "Share" feature, content is handed to the iOS system share sheet (UIActivityViewController). You choose which app to share to (e.g. Instagram, Messages, AirDrop). Once content leaves the App, it is governed by the receiving app's own privacy policy, and Dylvex bears no responsibility for that process.

資料儲存與保留 Data Storage & Retention
  • 所有由本 App 產生的影片暫存檔皆位於 iOS 提供的本機 temporary 目錄,僅在處理期間短暫存在,處理完成後系統可自動清除。您也可透過「iOS 設定 → 一般 → iPhone 儲存空間」手動管理。
  • 存入相簿的影片由 iOS 系統相簿(Photos.app)管理,不在本 App 的控制範圍,亦非本 App 所持有。
  • 本 App 不在裝置上保留任何使用者資料庫或個人資料檔案。
  • All intermediate video files generated by the App are stored in iOS's local temporary directory. They exist only during processing and may be automatically purged by the system. You can also manage them manually via iOS Settings → General → iPhone Storage.
  • Videos saved to your photo library are managed by the iOS Photos app and are outside the App's control or ownership.
  • The App does not maintain any user database or personal data files on your device.

兒童隱私 Children's Privacy

本 App 不刻意收集任何用戶資料,包括 13 歲以下(或歐盟地區 16 歲以下)兒童的個人資料。本 App 適合所有年齡層使用,且不含任何廣告或追蹤機制。

The App does not intentionally collect any user data, including personal information from children under 13 (or under 16 in the European Union). The App is appropriate for all ages and contains no advertising or tracking mechanisms.

您的權利(GDPR / CCPA) Your Rights (GDPR / CCPA)

由於本 App 不收集任何個人資料,歐盟 GDPR 及美國加州 CCPA 所賦予的資料存取、攜帶、修正、刪除等權利,在本 App 的使用情境下均無需透過我們行使。

您可隨時:

  • 透過「iOS 設定 → 隱私權與安全性」撤銷本 App 的相機、麥克風、相簿權限
  • 從裝置移除本 App;移除後所有本機暫存資料將同步刪除

若有任何疑問,請透過下方聯絡方式與我們聯繫。

Because the App does not collect any personal data, rights granted under EU GDPR and California CCPA (such as access, portability, correction, and deletion) do not require any action on our part in the context of this App.

You may at any time:

  • Revoke the App's camera, microphone, or photo library permissions via iOS Settings → Privacy & Security
  • Delete the App; this also removes all locally cached temporary files

If you have any concerns, please contact us using the information below.

資料安全 Data Security

由於本 App 不傳送任何資料至外部伺服器,不存在網路傳輸風險。裝置本機的資料安全由 iOS 系統的沙盒機制與裝置加密(Data Protection)負責保護。

Because the App does not transmit any data to external servers, there is no network-transmission risk. Local data on your device is protected by iOS's sandboxing model and device-level encryption (Data Protection).

政策變更 Changes to This Policy

若本政策有任何重大變更,更新版本將於本頁面公告,並更新「最後更新日期」。繼續使用本 App 即表示您同意更新後的政策。

If this policy changes materially, the updated version will be posted on this page with a revised "Last updated" date. Continued use of the App after changes are posted constitutes acceptance of the updated policy.
