TL;DR: CookieVault Guardian is a privacy extension from MDL Asia that watches your browser cookies in real time. It detects abnormal writes and third-party tracking, raises instant alerts, and gives you one-click cleanup plus privacy reports — so tracking happens on your terms. Live at cookievault.net/guardian.
Most tracking is invisible: third parties drop and update cookies as you browse, and you never see it happen. CookieVault Guardian makes that activity visible and controllable, turning your browser from a passive target into something you actively defend.
Real-time monitoring, not after-the-fact cleanup
Where many privacy tools only clear cookies after the fact, CookieVault Guardian does real-time monitoring of cookie changes as they occur. The moment something writes or modifies a cookie, Guardian sees it. That live view is the foundation for everything else it does.
Catching what shouldn't be there
Guardian focuses on the cookies that matter for your privacy:
- Anomaly alerts — get notified when an abnormal or unexpected cookie write happens.
- Tracking detection — surface third-party trackers that follow you across sites.
- Privacy reports — see a clear summary of what's been tracking you and how often.
Instead of a vague sense that "websites track me," you get specifics: which domains, how many writes, and when.
Stay in control
Visibility is only useful if you can act on it:
- One-click cleanup removes unwanted cookies instantly.
- Whitelist management lets you allow the cookies you actually rely on — your bank, your email, the sites you trust — so legitimate sessions keep working while everything else stays under scrutiny.
This balance matters: aggressive blocking breaks logins, while doing nothing leaves you exposed. Guardian lets you tune where that line sits.
Who it is for
- Privacy-conscious users who want to see and stop tracking
- Security teams monitoring for abnormal cookie behavior
- Anyone who wants control over what follows them across the web
CookieVault Editor vs. Guardian
The two CookieVault tools are complementary. Editor is for managing cookies — editing, backing up, and migrating them. Guardian is for defending against unwanted cookies — monitoring, alerting, and cleanup. Many users run both: Editor for control, Guardian for protection.
Frequently Asked Questions
What does CookieVault Guardian do? It monitors browser cookies in real time, detects abnormal writes and third-party tracking, and provides instant alerts, one-click cleanup, and privacy reports.
How is Guardian different from CookieVault Editor? Guardian protects you by monitoring and cleaning up tracking cookies in real time. Editor manages cookies — visual/JSON editing, backup, and migration. They work well together.
Will it break my logins? No, if you use whitelist management. You can allow trusted sites' cookies so your sessions keep working while unwanted trackers are flagged and removed.
Does it work in real time? Yes. Guardian watches cookie changes as they happen rather than only cleaning up afterward.
