The iSub Player Privacy Policy explains our rules regarding the processing of personal information. When you use this app, the relevant personal information processing activities will be carried out in accordance with applicable laws and regulations and the Privacy Policy.

When you use a specific feature, that feature may have separate agreements, service rules, or dedicated instructions.

II. About iSub Player Services

2.1 Service Content

iSub Player is a multimedia player application that provides you with the following services:

Media Playback: Supports playback of various video and audio file formats, including HDR video playback
Subtitle Features: Supports loading and displaying external subtitles, built-in subtitle extraction, dual-language subtitle display
Media Library Management: Importing, categorizing, and managing local media files
Favorites: Subtitle favorites, word favorites, favorites folder management, and folder encryption
Subtitle AI Analysis: This app provides functions to assist you in accessing third-party AI services. Based on operations you actively initiate, the app may, on your device, generate a prompt from selected subtitle segments, words, or other related text, and write the prompt to your device clipboard, then launch the third-party AI app installed on your device or open the corresponding web version via system-provided browser components (Android Custom Tabs / iOS SFSafariViewController; falling back to the system browser when unavailable). Writing to the clipboard does not mean the content has been sent to the third-party service; whether and when to paste or submit is decided by you. iSub Player does not automatically paste or submit the prompt to the third-party AI service. iSub Player's own processing of the relevant content, and the processing performed by the third-party service provider after you actively paste and submit, are governed respectively by this app's Privacy Policy and the respective third party's user agreement and privacy policy.
Word-lookup/Translation websites: The app opens third-party word-lookup/translation websites such as Youdao, Baidu, and Google Translate via system-provided browser components (Android Custom Tabs / iOS SFSafariViewController, falling back to the system browser when unavailable). The word you look up is sent to that website by the browser as a URL parameter. iSub Player does not actively read, extract, or collect web content, login credentials, or other information within those third-party websites. Such third-party websites are opened via system-provided browser components or the system browser, and their web content and login state are managed by the respective platforms and browser mechanisms.
Advertising Services: Non-Pro users will see splash ads and rewarded video ads when using the app. Users can gain temporary Pro experience by watching rewarded video ads. Pro users are not shown any in-app ads during the license validity period. The initialization and data processing of related ad SDKs are subject to this app's actual implementation and the descriptions in the iSub Player Privacy Policy.

2.2 Service Modification, Interruption, or Termination

Given the special nature of network services, you agree that we have the right to modify, interrupt, or terminate some or all services for reasonable causes (such as business adjustments, technical upgrades, or compliance requirements); for major adjustments, long-term service suspensions, or changes that may affect your paid entitlements, we will fulfill our notification and corresponding handling obligations as required by law.
We may, based on business operation needs, regularly or irregularly inspect and maintain the application services, related systems, or equipment, and will minimize the impact on the services. Where service is temporarily interrupted due to reasonable maintenance, we will take necessary measures within a reasonable scope; liabilities that we should bear under applicable law are not excluded by this provision.
If any of the following situations occurs, we may, based on the nature, severity, and impact of the conduct and the requirements of laws and regulations, take reasonable measures such as warning, limiting some features, suspending services, or terminating services:
- You violate this Agreement, and the relevant conduct reaches a degree that warrants corresponding measures;
- You use this app to engage in illegal or non-compliant activities;
- Other circumstances where laws and regulations require, or it is necessary to take corresponding measures to safeguard service security or the legitimate rights and interests of other users.
For situations that can be promptly corrected, we will, where reasonably practicable, give you an opportunity to remedy; except where the law requires or urgent security risks necessitate immediate measures.

2.3 Data Processing After Service Termination

After service termination, we will delete or anonymize the personal information we actually control in accordance with applicable laws and regulations and the iSub Player Privacy Policy. For data that laws and regulations require to be retained or that requires a reasonable period to process technically, we will continue to take protective measures to the necessary extent and process it in accordance with the law after the relevant grounds cease.
Service termination does not affect our legal obligations regarding personal information that has not yet been deleted, is retained pursuant to law, or remains under our processing.
The retention and deletion of media files, subtitles, favorites records, and other data stored locally on the user's device depend on the user's device operations and the app's actual functions; except where laws and regulations provide otherwise or this Agreement expressly provides otherwise.

4.2 Your Rights

The content you create through iSub Player, such as favorites and playlists, and the related rights thereto are determined in accordance with applicable law. For media files, subtitles, and other third-party content you import, the rights thereto are enjoyed by you or the respective rights holders in accordance with the law; importing or using such content does not by itself alter the original ownership of those rights.
Results generated by using translation, AI analysis, and other features are for personal learning and reference only and do not constitute any copyright transfer or authorization. To the extent permitted by law, users bear responsibility for intellectual property disputes arising from improper use of AI-generated content; this provision does not shift liabilities that iSub Player is required to bear under applicable law.

4.3 Processing of User Content

The content you import or create through iSub Player, including favorites, playlists, subtitle favorites, word favorites, etc., and the related rights thereto belong to you or the respective rights holders in accordance with applicable law.
To enable the features you actively use, we may read, store, organize, and process the relevant content to the extent necessary. For operations completed locally on your device, such as media playback, subtitle display, and favorites management, the relevant processing takes place on your device, and your use of this app does not by itself grant us the right to upload such content to our servers.
If this app actually provides cloud synchronization or other features that require server-side processing of user content, before enabling such features we will, in accordance with applicable laws and regulations and the iSub Player Privacy Policy, explain the processing purpose, content scope, and related methods, and obtain your consent where required by law.
You may delete content you create or save through the functions provided by the app. Deleting in-app records does not by itself delete the original media files on your device; where server-side synchronized copies exist, their deletion is subject to the actual implementation of that feature and the iSub Player Privacy Policy.

4.4 Restrictions

Without our written consent, you must not copy, disseminate, display, modify, or authorize others to use the protected content owned by us or controlled by us under law in the iSub Player application in any form; this restriction does not affect the rights you enjoy in accordance with laws and regulations (such as fair use).
