Clone Radar is a Chrome extension that scores commenters on Facebook for how likely they are to be clone, bot or impersonator accounts. It works entirely inside your browser.
What Clone Radar reads
It reads only pages on www.facebook.com and web.facebook.com, and only what Facebook already shows you:
- Comments on screen: the commenter’s name, profile link, badges (“New member”, “Admin”…), the comment text, and the description Facebook gives attached images.
- The post: its author and the start of its caption.
- Profiles: when you open a profile, or press Check recent posts, it reads up to 10 recent posts: whether each is a share or the person’s own, which Page it came from, and its hashtags and links.
What it stores, and where
Everything is stored with Chrome’s extension storage, in your browser profile:
- Settings: on/off, language, sensitivity and the display options. If you use Chrome sync, Chrome syncs these through your Google account. They contain no Facebook data.
- Trusted accounts: the name and profile key of each account you mark as trusted. Kept until you clear them.
- Profile checks: what was read from a profile’s recent posts. Kept up to 60 days (at most 1,000 profiles).
- Farm memory: accounts caught copy-pasting or in a tag ring, and which posts that happened on. Kept up to 90 days (at most 3,000 accounts).
- Your labels: for each account you mark Clone or Real, a case with the comment, image description, post caption, page address, score and reasons, plus your note. Kept until you delete them.
- Custom rule weights: only if you apply the suggestions on the “How detection works” page.
What it sends
Nothing. Clone Radar has no server, no analytics, no ads and no third-party code. It never sends what it reads or stores to anyone, including the developer.
The CSV report and the labelled-case export are files saved to your computer, only when you click Export.
