Privacy Policy

When you visit, enter a video link or videoId, view subtitles, or use translation and export features, this policy explains how we handle related data.

• “Personal Information” refers to data that can identify an individual (e.g., IP addresses may be considered personal information in certain jurisdictions).
• “Processing” refers to any operation on data, including collection, transmission, caching, display, export, and deletion.

• Video identifiers and addresses: the URL or videoId you input, used to fetch subtitles and basic video information.
• Subtitle content: timestamps and text, used for display on the page, copying, and export (TXT/SRT/VTT). Basic text cleaning is applied to improve readability.
• Basic video information: title, author, likes (where obtainable), used to enhance viewing and export experience.
• Translation text: when you enable translation, subtitle text is sent to public translation services and results are returned.
• Runtime and error logs: to ensure service stability, the server may record timestamps, request paths, response status codes, a small set of standard HTTP headers (such as User-Agent and IP), and error information.

We do not require you to create an account, log in, or upload local files, and we do not proactively collect contacts, precise location, or payment information.

• Subtitle fetching: reads publicly available subtitle data via official or mirror endpoints.
• Basic info fetching: extracts title and author through public web metadata or compatible endpoints.
• Text cleaning: simple denoising and tag removal to improve reading quality.
• Short-term caching: LRU in-memory cache is used to store results for faster responses, expiring automatically.
• Export and copying: file generation happens locally in your browser; copying writes directly to your clipboard and is not uploaded to the server.

• YouTube: reads subtitles and basic video information from public webpages and endpoints, subject to YouTube’s terms of use.
• Translation services: sends subtitle text to public machine translation services to return results.

Third parties have independent privacy policies and data processing rules. Please refer to their policies and make your own assessment when accessing or using third-party resources.

We do not use third-party cookies for advertising or cross-site tracking, nor do we proactively set custom persistent cookies. For basic functionality and security, your browser, framework, or hosting provider may automatically set a small number of necessary technical cookies (e.g., session and routing markers). These cookies are used only for technical operation, not for profiling or cross-site tracking.

Cookies are small text files stored in your browser by websites or third parties to identify sessions, retain preferences, or enable security and statistical functions. Common classifications include:

• By lifespan: session cookies (expire when the browser closes) and persistent cookies (expire after a defined period).
• By source: first-party cookies (set by the site you’re visiting) and third-party cookies (set by embedded external services such as video players).
• By purpose: necessary and functional (login sessions, routing, language preferences), analytics and performance (visit counts, error rates), and advertising/personalization (ad delivery and measurement).

• Necessary cookies: may be set automatically by frameworks or hosting platforms for basic operation and security; not used for advertising or tracking.
• Functional preferences: language and similar preferences are primarily inferred via URL paths; we currently do not rely on cookies for persistent storage.
• Third-party and advertising: embedded third parties such as the YouTube player may set cookies under their own policies for advertising delivery or personalization; these are controlled by the third party. The Website does not participate in ad targeting or cross-site tracking.
• Disable and control: you can disable or block third-party cookies, control per-site behavior, or clear history in your browser’s privacy settings; using incognito/private mode can also reduce cookie writes.
• Ad personalization control: on third-party accounts (e.g., YouTube/Google), you can disable ad personalization or manage cookie preferences to reduce ad-related cookie usage.
• Impact of disabling: in most cases, disabling cookies will not affect core functions such as subtitle fetching, viewing, and export, but it may affect stability of protections or routing capabilities provided automatically by platforms.

Examples of possible third-party cookies (subject to third-party policies; names and durations may change): from YouTube/Google, YSC, VISITOR_INFO1_LIVE, PREF, CONSENT for session identification, player functions, or preferences; from ad networks (e.g., doubleclick.net), IDE for ad measurement and frequency control. These cookies’ setting, purposes, and retention are managed by the third party.

To avoid inconsistencies caused by differences between server and client environments, we set a default time zone (UTC) in internationalization configuration to improve display consistency. This setting does not involve personal information and is not used for tracking.

We do not sell your personal information. Data may be disclosed only in the following circumstances:

• Interacting with necessary third parties to fulfill your instructions (e.g., translation services or video platforms).
• Fulfilling legal obligations or responding to valid law enforcement and regulatory requests.
• Protecting service and user security, and preventing fraud and abuse.

This Website targets a general audience and is not directed at minors, nor does it specifically provide services or content for minors.

• Information minimization: do not submit any sensitive personal information via inputs or contact channels (including real name, address, phone number, school and class, ID/passport numbers, payment information, etc.).
• No proactive collection: we do not perform age identification or verification, nor do we proactively collect minors’ personal data; if we discover personal information related to minors was submitted inadvertently, we will delete or anonymize it as soon as possible.
• Guardian rights: guardians may request access, deletion, or restriction of processing of data related to minors (within legal and technical feasibility) via the “Contact” entry or by emailing liboom139@gmail.com.
• Third-party content: embedded third parties (e.g., YouTube player) may present platform-related content and settings; guardians should manage and restrict usage with relevant parental controls and privacy settings provided by the third party.
