FAQ

How does PhobiaBlock detect images?+
PhobiaBlock scans image metadata, filenames, alt text, and surrounding text on the page for phobia-related keywords. It runs entirely in your browser — no data is sent anywhere.
What is Aggressive Mode?+
When Aggressive Mode is on (default), PhobiaBlock checks the page URL and title. If it contains a phobia keyword — like searching 'clowns' on Google — every image on that page is blocked automatically. No exceptions. This is the strongest level of protection.
Does it slow down my browsing?+
No. Text detection is instant and lightweight — it just reads text that's already on the page. Most users notice zero performance impact.
Is it really free?+
Yes! All features are free with no limits. No account, no trial, no paywall.
Can I still see blocked images if I want?+
Yes! Enable 'Click to Reveal' in settings. Blocked images show a safe overlay, and you can click to reveal them when you're ready.
Does it work on all websites?+
PhobiaBlock works on virtually all websites including Google Images, Reddit, Twitter/X, Facebook, Instagram web, news sites, and more. You can also whitelist specific sites.
Does it work in languages other than English?+
Yes. PhobiaBlock detects phobia keywords in 11 languages: English, Korean, Japanese, Chinese, Spanish, French, German, Portuguese, Italian, Russian, and Arabic. Browse foreign-language sites with the same protection.
