Yes! All features are completely free forever. No subscriptions, no hidden fees, no premium tiers. We're open-source and community-driven.

Do you collect my data?

No. We don't collect, store, or sell any of your browsing data. All privacy protection happens locally on your device — nothing leaves your browser.

Why is it free? What's the catch?

No catch! Gecko Guard is a passion project built by privacy advocates. It's MIT licensed open-source software. We believe privacy protection should be free for everyone.

Can I trust an open-source extension?
