URL Lookalike Blocker collects no data. All processing happens locally in
your browser. No information about the URLs you visit, the domains the
extension blocks or warns about, or your extension settings is transmitted
to any server.

What is stored locally (via browser.storage.local):
- The set of languages whose Unicode scripts you have permitted beyond
your locale defaults.
- The list of domains you have explicitly whitelisted.
- Your interface preferences (theme choice; whether drop shadows are
shown; whether the private-browsing warning is dismissed).

A small localStorage cache holds two of those preferences (your theme and
the show-shadows setting) so the next page-load can apply them
synchronously and avoid a brief flash of the previous theme. This cache
contains only those two values and never leaves your browser.

Everything listed above is stored on your device only and is removed if
you uninstall the extension. The extension does not modify page content,
inject scripts into pages, read browser history or cookies, or use any
third-party analytics, tracking, or telemetry.
