The short list
FerrLens sets no cookies. Not for analytics, not for advertising, not for
session management (there's no account yet). The login flow that will land with the account
system in V1.1 uses an httpOnly session cookie scoped to .ferrlabs.com, set by auth.ferrlabs.com — that cookie is documented in the FerrLabs holding site's
own cookie policy.
What this means
- No cookie banner. None of the cookies we don't set need consent.
- No tracking. We don't run Google Analytics, Plausible, Fathom, Posthog, anything.
-
Your URL bar state on a tool page (the
#token=…share fragment) lives in your browser; it's never sent to our server.
localStorage / sessionStorage
Same answer: none. Tools persist state in the URL hash (so it's shareable), not in browser storage. If we ever add a "recent scans" list backed by localStorage we'll document it here.
Third-party cookies set inside our pages
None.
Changes
If we add even a single cookie (analytics, A/B testing, etc.), this page lists it before it ships, and the change is announced in the FerrLabs changelog. No silent additions.
