PRIVACY & LIMITATIONS
Dialogue stays in your browser. You keep control of the timeline.
SRT/WebVTT text you paste or explicitly choose, QA thresholds, and retimed results stay on the current page by default. CaptionCheck does not upload captions, open associated video, or read your system clipboard or captioning software.
Editing aid, not platform approval
The tool recognizes common SRT/WebVTT timing lines, flags configurable minimum/maximum duration, line count, characters per second, and adjacent overlap, and can apply one millisecond offset to every cue; negative results are clamped to 00:00:00,000. It does not play video or validate picture-safe areas, speakers, semantic line breaks, bidirectional text, styles, frame rate, or audiovisual sync, and it is not Netflix or client certification.
Caption text and exports can be sensitive
Process only captions you are authorized to view, preferably on a trusted device. The page does not persist caption content; refreshing or closing discards the current text and results. SRT/VTT downloads contain the complete dialogue, while the issue CSV includes cue numbers, times, rules, and values. Browser extensions, screen sharing, and the downloads folder may still expose these files, so review them before sharing.
Advertising and local preferences
This page uses Google AdSense Auto Ads. Google may use cookies or similar technologies under its policies. .miluland.com domain cookies sync language, theme, high contrast, a six-item recent-tools list, and up to 16 favorite tool IDs across MiluLand sites. These values never contain inputs, files, or results; the current site also keeps a local compatibility copy.
← Back to toolLocal report studio
The report studio reads only the workbench’s currently visible result summary for local preview, Markdown copy, JSON download, printing, and a SHA-256 fingerprint. It never reads input controls or original files and is not persisted unless you choose to download it.
Optional local checkpoints
Only when you explicitly choose Save does the tool write the visible result summary, time, and optional short label to this site’s browser storage, up to five entries. Imported files and input-control contents are never stored; you can export, restore same-tool checkpoints, or clear them at any time. Imports are limited to 128KB and validate the tool, timestamp, summary, and label of up to 80 characters.
Analytics and your choices
Google Analytics measures page visits and tool openings. Visitors in the EEA, UK, Switzerland, mainland China, Canada, South Korea, and Türkiye are asked first; other identified regions start automatically. A previous refusal, GPC, or Do Not Track takes precedence. Tools work with either choice.
We use same-site Cloudflare connection information to determine the country or region, not your language, and do not save the IP address in the lookup. If the lookup fails, the Google tag still starts with regional consent defaults: analytics cookies in consent-required regions await permission, while Google may receive basic cookieless signals. Automatic startup is not recorded as your explicit consent.
Files, filenames, tool inputs, search terms, URL parameters, fragments, and results are excluded. Page names use fixed paths and referrers contain only the source site. Google processes visit identifiers and technical browser information. Enhanced measurement, Google signals, and ad-personalization measurement are disabled.
Turn analytics on or off through Privacy & analytics in the footer. Explicit choices are shared across enabled pages in a .miluland.com cookie for up to 180 days; automatic startup does not save an accepted choice. Turning it off stops this integration and clears accessible GA cookies. Advertising uses separate consent settings.
