Optery vs. Sentry AI
Optery charges up to $249/year to scrub data broker websites, but does nothing to stop trackers, surveillance networks, or AI scrapers from harvesting you while you browse. Sentry AI is 100% Free, provides active in-browser defense against 120,000+ trackers, and gives you a zero-knowledge local encrypted vault where your data stays on your machine.

Frequently Asked Questions
Why is active in-browser defense essential?
Even if a removal service deletes your old records, every website you visit continuously collects your IP, location, canvas fingerprint, and browsing habits, selling them back to data brokers. Sentry AI breaks this cycle by blocking the trackers and AI scrapers at the point of origin.
Does Sentry AI require my credit card or email?
Never. Sentry AI requires no account creation, no email address, and no credit card. You simply add the extension to your browser, and protection begins immediately with zero telemetry.
