YouTube Check Marks YouTube videos you've rated (Like or Dislike) with a Viewed badge on thumbnails across the platform. YouTube Check helps you avoid re-watching videos you've already rated on YouTube. HOW IT WORKS • Open any YouTube video and give it a Like or Dislike • The extension saves your rating locally in your browser • While browsing Home, Search, Channels, Playlists, Shorts, and both the suggested videos and the playlist queue beside the video you're watching, rated videos show a "✓ Viewed" badge on thumbnails FEATURES ✓ Automatic Like/Dislike detection — Likes given on your phone or TV are picked up from your "Liked videos" list ✓ Mark as viewed by watch time — flags a video once you've watched a configurable amount of it (75%–95%, default 90%), even without rating it ✓ Configurable badge or overlay on thumbnails ✓ Optional: show the full video title on cards, with no "…" cut-off ✓ Full YouTube Shorts support ✓ Floating page counter (viewed/total on the current listing) — reports your progress through a playlist while you watch one; dismissible per page and draggable to any position (double-click to reset) ✓ Watch page and Shorts indicator ("You already rated this video" / "You already watched this video") ✓ Popup with statistics and recent history — including how many videos you've viewed today, this week and this month; click any total to list every video behind it; remove individual videos or clear everything ✓ Automatic history cleanup (keep forever, or 30 / 90 / 180 / 365 days) ✓ Export and import your data (JSON) ✓ Settings synced across devices via Chrome Sync ✓ Optional cloud sync — the same history and settings in Chrome, Edge and Brave, with a free account; on the website, your history, statistics by channel and connected browsers (early access, free for a limited time) ✓ New: light, dark or automatic theme in the popup and the settings ✓ Welcome guide on install and English / Portuguese interface PRIVACY • Without an account, no data leaves your browser: everything is stored locally • Cloud sync is optional and only starts after you create an account and turn it on • You can clear your history, export your data or delete it from the cloud at any time • Privacy policy: https://youtubecheck.com.br/privacidade Perfect for anyone who watches a lot of YouTube and wants to quickly see what they've already rated. [ WHAT'S NEW — version 1.15.0 ] • Connecting cloud sync now opens the youtubecheck.com.br website in a regular tab instead of a separate window, with a dialog in the settings that follows each step and returns to them once connected • Signing up with email confirmation, a passkey or a password manager works there as on any website, and closing the settings midway no longer loses the authorization • Confirmations (turn off sync, restore defaults, clear history) now use the extension's own dialog, in the chosen theme, instead of the browser's message box • The extension no longer asks for the identity permission
