Privacy Policy

Last updated: 2026-08-30

YouTubeThumb.com is a free public-image tool. There is no account and you do not upload files.

Public site: https://youtubethumb.com. Privacy questions: contact@youtubethumb.com.

Thumbnail downloader (homepage)

The homepage YouTube thumbnail downloader runs in your browser. The watch URL or video ID you paste is used in this tab to request public JPGs from YouTube’s thumbnail servers (img.youtube.com). That link is not sent to youtubethumb.com for the thumbnail job.

Channel banner and profile picture tools

The channel banner download and profile picture downloader need a short same-origin lookup. The public channel or video URL you paste is sent to /api/channel-images on this site so Cloudflare Pages can read the public YouTube channel page and return the banner and avatar addresses YouTube already shows.

Copy and download of those images go through /api/channel-image-file, which only fetches files from YouTube’s image hosts (yt3.ggpht.com, yt3.googleusercontent.com). Other image hosts are rejected.

Those requests are not stored as an account, a history, or an image archive. Ordinary hosting logs may still record the API path and the query string.

What the tools do not keep

  • A user account
  • A copy of the downloaded JPG on this site
  • A searchable history of pasted links

Refresh or close the tab to clear page memory. Downloads stay in the folder your browser uses.

Theme preference

Light or dark theme may be stored in LocalStorage. It is not tied to the video or channel link. Clear site data to remove it.

Hosting logs

The site runs on Cloudflare Pages. Ordinary logs may include IP, path, user agent, timestamps, and security events.

For the homepage thumbnail tool, those logs are not a copy of the YouTube link you pasted. For banner and avatar lookups, the request URL may include the public YouTube link or video ID you submitted, because that is how the lookup works.

Feedback form

The header Feedback button sends the text you type to a self-hosted Feedback Hub on Cloudflare Workers (feedback-hub.pvb-259.workers.dev). Typical fields: type (bug, idea, question, thanks, other), message, email, page URL, language, and basic diagnostic context. Email notifications go through the configured Cloudflare email service.

The form does not attach the YouTube link or the image file automatically. Do not paste passwords, ID numbers, or private documents.

Email

If you write to contact@youtubethumb.com, we receive whatever you put in that email. Treat email as a mailbox, not a vault.

Analytics

On the production site, PageView records page-view traffic using this site’s domain, the current URL, and the referrer when available. It does not receive the YouTube link from the homepage thumbnail form. Banner and avatar lookups are API requests, not PageView events.

If a Microsoft Clarity project ID is installed, Clarity loads after the page load event (idle, with a short fallback) and may analyze rendering and interactions such as clicks, scrolling, and mouse movement. Cookie behavior depends on region, project settings, and consent.

Cloudflare may also collect Web Analytics if Insights is on for the zone.

Local astro dev / preview does not load these scripts. They appear in the production build only.

Ko-fi

The feedback modal may link to ko-fi.com/dylan199. Opening that link is optional and uses Ko-fi’s own policy.

Retention

  • Homepage thumbnail input: until you clear it or close the tab. It is not sent to this site.
  • Banner and avatar lookup: used for the current request. Not kept as a history. Hosting logs follow the host’s normal operations.
  • Theme: until you clear site data.
  • Feedback and email: long enough to understand the report.
  • Analytics: each provider’s retention.
