1. Operator and contact

2. What we collect and how

There is no sign-up or login, and the site never asks for your name, email address, phone number or similar details.

When you view the site, your IP address, browser and device information, the pages you visit and when, and the page that sent you here are passed automatically to the services below.

  • Google Analytics 4: uses cookies (such as _ga). It records page views, scrolling, outbound link clicks, file downloads, form interactions and video engagement. Its user-provided data collection feature is turned off.
  • Cloudflare Web Analytics: counts page views without cookies.
  • Google AdSense: uses cookies and similar technologies to show ads (see section 7).

When you use TV mode (/play, /ctrl), the following is added.

  • Firebase anonymous authentication gives your browser a temporary identifier.
  • The pairing code, the playlist (video IDs and titles) and the playback state are kept in the Firebase Realtime Database.
  • Google Analytics is not loaded on TV mode screens.

3. What is stored in your browser

The following is stored in your browser. The language cookie is read by our server so the site opens in the language you chose; the rest is never sent to our server. Clearing it in your browser settings removes it.

  • Recently watched videos: localStorage
  • Your language choice: cookie trenvid_lang, 1 year
  • TV mode settings (remembered pairing code, country, language): localStorage
  • If you used TV mode, Firebase anonymous sign-in data: IndexedDB (Firebase uses it for the TV mode connection)

4. Why we use it

  • To provide charts, video information and TV mode
  • To analyse usage and improve the service
  • To show ads

5. How long we keep it

  • Google Analytics: 2 months
  • TV mode data: deleted when the big screen is closed and the connection ends. A pairing code that is never connected expires after 10 minutes.
  • Information in your browser: until you clear it (the language cookie lasts 1 year)
  • Information processed by AdSense and Cloudflare: under each company’s own policy

6. Sharing, processors and international transfers

We do not sell personal information or give it to third parties. The companies below process it on servers outside Korea, including in the United States.

  • Google LLC (United States): Analytics, AdSense, Firebase (anonymous authentication, Realtime Database), YouTube (player, thumbnails)
  • Cloudflare, Inc. (United States): hosting, Web Analytics

This site uses YouTube API Services to fetch public information about videos (title, channel, view count and so on). None of your information is sent through this API. The YouTube Terms of Service (https://www.youtube.com/t/terms) and the Google Privacy Policy (https://policies.google.com/privacy) apply.

7. Cookies and ads

Third-party vendors, including Google, may use cookies to show ads based on your visits to this and other websites. You can opt out in these ways.

8. Content from other services

  • Videos play in the YouTube player (youtube-nocookie.com). When you play a video, YouTube may process cookies and device information.
  • Thumbnails load from YouTube’s servers (i.ytimg.com).

9. Your rights

  • Our server keeps no information that can identify you.
  • You can clear what is stored in your browser yourself. Send any other request to support@zzxxccvv.com.

10. Children under 14

The site does not ask for your age and does not knowingly collect personal information from children.

11. Changes to this policy

If this policy changes, the new version will be posted on this page with an updated revision date.
