Privacy Policy for Manga Reader: AI Translator
Last updated: October 11, 2026
Information Collection and Use
The Application supports on-device and cloud translation:
- On-device translation: text is translated locally using Apple’s Translation framework. This translation operation does not send dialogue text or a device identifier to the Service Provider’s cloud translation server.
- Cloud translation: this feature uses the server-based translation service described below, including when cloud automatic translation is enabled.
- The Service Provider does not use advertising identifiers or embed third-party tracking tools in the Application. Websites opened in the in-app browser may use their own cookies and tracking technologies, subject to their own privacy policies.
Cloud Translation
When you use cloud translation, the Application sends the following data to the Service Provider’s server:
- Text to be translated: dialogue text or bookmark titles, used to provide translations.
- An app-generated identifier (UUID): generated and stored by the Application to distinguish requests for usage management and abuse prevention. It does not contain your name or Apple ID, but can link requests made with the same identifier.
- Source and target languages: used to select the translation languages.
- Purchase status and request type: used for service operation and to distinguish requests such as bookmark-title translation. The request type is a category, not the page URL.
The text is sent from the Service Provider’s server to Google’s Gemini through Google Cloud (Vertex AI) for translation. Source images and entire book files are not uploaded for cloud translation.
When cloud automatic translation is enabled, text is sent automatically as pages are displayed or processed in advance. You do not need to press the translation button for every page.
AI Explanations
Dialogue explanations: the Application sends the original text, translated text, language and instructor settings, and the app-generated identifier to the Service Provider’s server. Text and settings needed to generate the explanation are sent to Google’s Gemini.
Story explanations: the Application sends the page URL, page title or manually entered work title, target language, identifier, and purchase status to the Service Provider’s server. The URL, title, and information needed to generate the explanation are sent to Google’s Gemini. This feature may also use Google Search to obtain supporting information. On iOS and iPadOS, the identifier used for this feature is Apple’s identifier for vendor (IDFV), which is different from the app-generated translation identifier. On macOS, this feature currently sends a fixed placeholder instead of a device-specific identifier.
Support Inquiries and Ad Reports
When you submit an inquiry through the Application, your email address, inquiry category, message, app name, and any optional target URL are sent to the Service Provider’s server to respond to the inquiry and investigate issues. If you enable device-information attachment, the submission also includes device type, OS name and version, app version and build, locale, and purchase status.
When you report an ad or a website for ad-blocking support, the reported URL and report time are sent to the Service Provider’s server for investigation and filter maintenance.
These submissions are processed using Google Cloud and, where configured, forwarded to Google Apps Script. Inquiry contents and ad-report information are recorded in server logs.
Location Information
The Application does not collect precise location information from your device.
Local Files and Content
The Application may access user-selected images, archives, and folders for reading and translation. These files are processed on your device. When you use cloud translation, dialogue text extracted from the content is transmitted as described above; the source images and files are not uploaded.
Privacy and Security
On-device translation processes text locally. Cloud translation and AI explanations send the information described above to the Service Provider’s server and use Google’s Gemini to process the relevant text. The Service Provider does not sell personal information or use translation content for advertising purposes.
Third-Party Services
On-device translation uses Apple’s Translation framework. Cloud translation and AI explanations use Google’s Gemini through Google Cloud (Vertex AI). The Service Provider does not use submitted translation or explanation content to train AI models. Google states that it does not use customer data to train or fine-tune AI models without the customer’s prior permission or instruction.
Restrictions on model training do not mean that data is never retained or processed for service operation. Google may retain or process data for abuse monitoring, caching, or search-grounded responses under the applicable terms and settings. Story explanations may use Google Search grounding.
Data Retention Policy
Translation and explanation content: content is processed to provide the requested results. Translations, explanations, and caches may be stored locally on your device. Server logs and Google’s data handling described below are separate from this local storage; this policy does not promise zero retention.
Server logs: the Service Provider’s server records operational information such as identifiers, language settings, purchase status, request types, text counts, processing times, and errors. Story-explanation logs can include work titles and, for some errors, URLs. Logs are used for service operation, troubleshooting, and abuse prevention. Hosting infrastructure may also record connection information such as IP addresses and request times.
Inquiries and reports: inquiry submissions, including email addresses and messages, and ad-report URLs and times are recorded in server logs and may be retained in the systems used to handle them.
Retention varies by the storage system and its configured retention and deletion settings; no single retention period is promised here. Google’s processing and retention are governed by the applicable service terms and settings. Contact the Service Provider for information about retained data or to request deletion; available action depends on the data and system concerned.
Where supported, you can remove local data using the Application’s deletion or cache-clearing features. Uninstalling the Application may not remove all local files, exported files, or backups, particularly on macOS. Removing local data does not delete server logs or submissions already sent.
Children’s Privacy
The Application does not knowingly collect personal information from children under the age of 13.
Changes to This Privacy Policy
This Privacy Policy may be updated as the Application or its data handling practices change. Updates will be posted on this page with a revised date.
Your Choices
If you do not want text sent to the Service Provider’s server or Google’s AI service for translation or explanation, use on-device translation, disable cloud automatic translation, and do not use cloud translation, cloud title translation, dialogue explanations, or story explanations. Inquiries and ad reports send information separately when you submit them. Websites you visit in the in-app browser also receive the requests needed to display their content.
Simply using the Application or reading content does not constitute consent to sharing data with a third-party AI service.
