Privacy Policy
Spoiler Guard for YouTube consists of a browser extension and a sharing site to protect your viewing experience from spoilers. This page details how data is handled.
Extension Data Processing
The extension reads comment, live chat, and chat replay text on YouTube pages inside your browser to match them against community lists or your personal rules. This process is used strictly for blurring or hiding potential spoilers.
Data Transmission
The extension reads comment, live chat, and chat replay content locally. It sends data to the official review endpoint only when you explicitly submit a list from the extension. A submission can include the selected comment or chat text, YouTube display name, message ID, displayed time, and video information needed to review a blocklist. The unreviewed originals are not publicly available and remain in a private review database.
Local Storage
The extension stores block settings, presentation styles, personal block rules, and curation candidates inside local extension storage (Chrome Storage). You can clear this data at any time by uninstalling the extension or clearing extension data.
Shared Information
Submitted lists are reviewed by an administrator and are not automatically published. If a list is approved, the generated public JSON keeps only the matching data needed by the extension, such as IDs, hashes, reasons, or timing rules; it excludes commenter names and comment text. We do not send individual acceptance or rejection notifications.
Website Data
This website is hosted on Vercel. To ensure stable operations and analytics, request metadata (time of access, browser agent, region) may be recorded by Vercel logs. Vercel may also temporarily use request source information to limit abusive traffic. Spoiler Guard does not persist IP addresses in the private review database.
Excluded Uses
We do not use collected or stored information for advertising, user tracking, selling to third parties, or identifying YouTube accounts.
Third Parties
We use Vercel for website hosting and analytics, and GitHub links for source code. Using these services applies their respective privacy policies.
Inquiries
For privacy questions, please open an Issue on our GitHub repository or contact via our distribution pages.
