Play The Web. Answer Surveys. Get Rewarded. Behavix turns your everyday browsing into paid surveys and rewards. Answer questions that actually match your interests, help brands build better products, and stay completely anonymous the entire time. GET MATCHED TO PAID SURVEYS Right now, you're invisible to brands. Activate anonymous data sharing and Behavix targets relevant paid surveys to you based on your browsing interests — no more boring, irrelevant questionnaires. ANSWER. EARN. REPEAT. Surveys arrive directly in the app. Tap one, work through a handful of questions, and you're done. New paid surveys arrive often, so check back whenever you want. HOW IT WORKS Behavix uses two device permissions to figure out which surveys you'll actually care about: • A local on-device VPN that observes which categories of sites your apps reach. Traffic stays on your device — we never see specific URLs or content. • A Safari extension that maps your browsing into broad, anonymous interest categories used for survey matching. PRIVACY FIRST • Your data is anonymous and never tied to your real identity • Your data is never sold • All collected data is encrypted and safe • You can revoke either permission from iOS Settings at any time • You can delete your enrollment from inside the app
