Site Transparency Checker
A tool claims your input “stays in your browser” — is that true? Enter a URL to surface, via static analysis, where the page could send data: external origins, trackers, and forms. Signals, not a verdict.
ITD's server fetches the target URL once and analyzes it statically (only the URL you enter is sent — not your code or input). Access to internal / private addresses is blocked.

How to truly verify (DevTools)
- 1Open the page, then open DevTools with F12 (or right-click → Inspect).
- 2Open the “Network” tab and make sure it's recording.
- 3Actually use the tool and watch whether new requests (Fetch/XHR/WS) go to external domains.
- 4If there are no external sends, the page is client-side for that action.
How to use
- 1Paste the URL of a tool that claims to be browser-only.
- 2It statically analyzes the external destinations, trackers, external forms and send-style code on that page.
- 3Results are signals. Do the final check in your DevTools Network tab (below).
Why it matters
Whether a “privacy” tool is truly private can't be fully proven from outside (browser CORS hides other sites' runtime behavior, and static analysis can't show the absence of a send). So this tool doesn't claim a verdict — it surfaces where data could flow and hands you the real verification method (DevTools). ITD is no exception: analyze this site and you'll see ad/analytics tags — not hiding it is the honest move.
FAQ
QDoes “zero external destinations” mean it's safe?
A
No. Static analysis misses obfuscated, dynamic, or on-click sends. Zero means “none found statically,” not proof. The sure check is your DevTools Network tab.
QWhy can't this be browser-only (no server)?
A
Browser CORS prevents a page from observing another origin's runtime requests, so the target URL is fetched and analyzed server-side (only the URL is sent).
QIs it OK to check someone else's site?
A
The tool fetches the target page once and analyzes it statically — no active scanning or attack (the same scope as opening it in a browser). Internal/private addresses are blocked.
