See what people are saying about Defenras.
Absolutely not. Defenras runs 100% locally on your device. No data is ever sent to any server. No analytics, no tracking, no telemetry. Your browsing history stays private.
Chrome, Microsoft Edge, Firefox, Brave, Opera, and Vivaldi. The Chrome version also works on any Chromium-based browser.
No. Defenras is under 1MB and uses local blocklists for instant lookups. Unlike some browser security extensions that slow down page loads with server-side scanning, Defenras processes everything locally with virtually zero performance impact.
Install the extension and all features work for 7 days — no credit card needed. After 7 days, protection pauses until you choose a plan. Your settings and data are preserved.
Yes! We offer a 30-day money-back guarantee. If you're not satisfied for any reason, contact us and we'll process a full refund, no questions asked.
Not if you set a PIN! The PIN Lock feature prevents anyone from changing settings or disabling shields without the correct code. Perfect for parental controls.
Guardian Alert is an opt-in feature for parents. Enter your email in Settings, and if someone uninstalls the extension, you'll receive an instant email notification with details like the browser and time. It only stores a random device ID and your email — no browsing data is ever sent.
Both include all features. Annual ($49.99/yr) renews each year. Lifetime ($199) is a single payment that gives you access forever, including all future updates. Lifetime pays for itself in 4 years.
