Privacy Tools
See what your browser reveals, check whether a password has appeared in a breach, strip trackers from links and clean hidden metadata from files.
- Browser Fingerprint Viewer Reveal the signals your browser exposes to trackers — user agent, screen, timezone, canvas hash and WebGL renderer — computed on this page and never uploaded.
- Password Leak Checker Check whether a password has appeared in a known data breach. Only the first five characters of its SHA-1 hash reach Have I Been Pwned — k-anonymity.
- Privacy Policy Generator Build a plain-English website privacy policy in your browser. Enter your site details, tick the data you collect, and copy the draft as HTML, Markdown, or text.
- URL Tracker Cleaner Strip tracking parameters like utm_source, fbclid and gclid from a single link or a whole list, entirely in your browser. See exactly what each URL was carrying.
Four different privacy questions live in this category, and each has its own tool. To see what your browser quietly hands to every site you visit — user agent, screen geometry, installed fonts, canvas and WebGL signatures — open the Browser Fingerprint Viewer; it adds up how many bits of identifying entropy those signals carry, which is the number that decides whether clearing cookies changes anything. To check whether one of your passwords has surfaced in a known breach, the Password Leak Checker answers without ever sending the password itself: it hashes your input with SHA-1 and transmits only the first five hex characters, so the server replies with a batch of candidates and the final match happens locally in your browser.
Before sharing a link, run it through the URL Cleaner to strip utm_*, fbclid, gclid and similar parameters that tie the click back to an advertising profile. And if you publish a site of your own, the Privacy Policy Generator drafts a plain-language template from what you actually collect — a starting point to customise, not legal advice.
Two of these have deeper companion reading: the browser fingerprinting guide shows how independent signals combine into a single unique identity, and the URL tracking guide breaks down what each parameter family — campaign tags, click identifiers, session leakage — is actually for and why stripping them occasionally breaks a link.
