ScamsShield browser extension

The free extension provides local website checks and ad/tracker blocking without a paid AI check. AI-assisted extension checks require the paid extension plan and are subject to its quota. Premium website tools and the paid extension plan are separate; the Bundle includes both. A warning check is a second opinion, not a guarantee.

What can I use for free?
The current website ZIP includes local warning checks for three distinct websites per UTC day per installation, plus ad/tracker blocking. No account is needed for those free features. Store releases may differ; check the installed version.
Do I need Premium for the extension?
Free local checks do not require a subscription. AI-assisted extension checks require the separate paid extension plan and use its quota. Website Premium is a separate product; the Bundle includes both.
Does a low-risk result prove a website is safe?
No. ScamsShield can miss scams or flag legitimate content. Verify important requests independently and never share passwords, verification codes or recovery phrases.
