Link privacy
Check a link before you share it
Share links can expose more than the page you intended. Long query strings may contain tracking parameters, signed access data or session-like tokens. Use the checker to review the destination and warning signs before forwarding a URL.
Check this linkWhat to look for
Review the final destination after redirects, especially when the visible link is shortened or comes from a message you did not expect.
Pay extra attention to parameters with names such as token, signature, session, credential or secret. A parameter name alone does not prove that the value is sensitive, but it is a reason not to repost the link publicly.
Deep Scan privacy protection
Can I Share This? separates its first-party warning-sign analysis from external reputation checks. The external check only runs after you confirm that the public URL may be shared with threat-intelligence providers.
The Deep Scan includes a guard that refuses URLs containing several common token- or signature-like parameter names. This reduces accidental disclosure, but it cannot recognize every private-link format.
Tracking parameters
Marketing parameters such as UTM tags are often harmless but can reveal campaign or referral information when a URL is forwarded. Removing unnecessary tracking can make a shared link cleaner and easier to inspect.
Use the tracking-removal tool for ordinary analytics parameters, but do not delete parameters from signed or authenticated links unless you understand what they do; changing them may break access.
Important limitation
A privacy check cannot determine every piece of information that a destination will collect after you open it. Cookies, browser fingerprinting, account state and scripts on the destination are separate from what is visible in the URL itself.
If a link grants access to a private document, use the sharing controls of the original service instead of relying only on the URL text.
No scanner can guarantee that a link or sender is safe.
