Privacy Policy for BookVoice Generator Last updated: 2026-06-17 BookVoice Generator (“the app”) is an Android application published by Hubert S. This Privacy Policy explains what data the app accesses, stores, uses, and shares. Contact: hubert.slabon@gmail.com Summary BookVoice Generator lets users import photos, PDFs, and e-book files, extract or clean text, generate speech/audio, and play the generated audiobook content. The app is designed to process user content locally on the device. The app does not require an account and the developer does not operate an app backend for storing user documents, extracted text, generated audio, folders, bookmarks, or playback progress. The app includes Google AdMob advertising. Google Mobile Ads SDK may collect and share certain data for advertising, analytics, and fraud prevention as described below. Data You Provide to the App The app may access and store the following data on your device when you choose to use related features: Photos or images that you take or import. PDF and e-book files that you import. Text extracted from imported files using OCR or e-book parsing. Generated audio files created from extracted text. Folder names, file names, bookmarks, playback position, processing status, app settings, selected language, selected voice, and downloaded model metadata. Local diagnostic files created during OCR, text, or speech processing. This content is stored locally in the app’s private storage or app-specific storage on your device. The developer does not receive this content unless you separately choose to send it outside the app. Local Processing The app uses local OCR, text processing, and text-to-speech components where available. Imported documents, extracted text, and generated audio are processed and stored on the device. The app may download optional OCR, language, or text-to-speech model files from third-party hosting services such as GitHub, Hugging Face, PaddleOCR/Baidu-hosted model URLs, or other model URLs listed in the app’s model catalog. These downloads require network access. The model hosting service may receive standard network information such as your IP address, device/browser request metadata, and download request details according to that service’s own policies. Advertising and Third-Party Data Collection The app uses Google AdMob through the Google Mobile Ads SDK and Google’s User Messaging Platform for consent and privacy options. According to Google’s Google Play data disclosure documentation for the Google Mobile Ads SDK, the SDK may automatically collect and share: IP address, which may be used to estimate approximate location. User product interactions, such as app launches, taps, and ad interactions. Diagnostic information, such as app and SDK performance information. Device and account identifiers, including the Android advertising ID, app set ID, and other applicable identifiers. Google states that this data is collected and shared for advertising, analytics, and fraud prevention purposes, and that data collected by the Google Mobile Ads SDK is encrypted in transit using TLS. You can learn more in Google’s documentation: Google Mobile Ads SDK data disclosure: https://developers.google.com/admob/android/privacy/play-data-disclosure Google Privacy Policy: https://policies.google.com/privacy Google advertising controls: https://myadcenter.google.com/ Depending on your region and Google requirements, the app may show a consent form or privacy options form for advertising choices. Permissions The app may request or use these Android permissions: Internet and network state: used for ads, consent forms, and optional model downloads. Notifications: used to show audiobook playback controls and playback status notifications. Foreground service: used for long-running playback-related behavior. Modify audio settings: used for audio playback and voice/audio processing features. The app uses Android file pickers and camera capture flows so you can choose files or create images for processing. Files are accessed only after you choose them or create them through the app. Sharing The developer does not sell user documents, extracted text, generated audio, folders, bookmarks, or playback progress. Data may be shared in these limited cases: With Google and Google’s advertising partners through the Google Mobile Ads SDK, as described in the Advertising and Third-Party Data Collection section. With third-party model hosting services when you download optional model files. With another app only when you explicitly use Android sharing/opening features or grant file access through the system. If required by law, regulation, legal process, or enforceable governmental request. Data Retention and Deletion User-created content and app metadata are stored locally on your device until you delete them in the app, clear app data, or uninstall the app. You can delete imported documents, folders, generated audio, downloaded models, and related local files from within the app where deletion controls are available. You can also delete all local app data using Android system settings or by uninstalling the app. The developer does not maintain a server-side user account or backend copy of your local documents, extracted text, or generated audio. For data collected by Google Mobile Ads SDK, deletion and control options are handled by Google and Android advertising settings. You may also contact the developer at the email above for privacy questions. Security Local data is stored in Android app storage controlled by the operating system. Network communication for ads and most downloads uses HTTPS/TLS. No method of storage or transmission is perfectly secure, but the app is designed to avoid transmitting user document content to the developer. Children’s Privacy The app is not directed to children. If the app’s target audience settings in Google Play are changed to include children, advertising and data handling settings must be reviewed again for compliance with Google Play Families policy and applicable law. Changes to This Policy This Privacy Policy may be updated when the app’s features, SDKs, or data practices change. The updated policy will include a new “Last updated” date.
