A little more privacy, right where you browse
Your browser.
Your rules.
Everyone deserves privacy. PrivXion helps Chrome users protect their browsing sessions and step away with confidence. Designed exclusively for Google Chrome.
I wanted to step away without leaving my browser open. Chrome had no simple session lock, so I built PrivXion for everyone who shares that need.

Read the story
Every day, we carry our lives into the digital world. Our conversations, our work, our ideas, and our dreams take shape on the screens before us. They deserve a space where we can feel at ease.
PrivXion was created for those everyday moments when you need to step away. It helps you lock supported browser tabs with a local passcode, giving you more control over your privacy while you’re away.
But PrivXion begins with a purpose that reaches beyond a single product.
At PromeXion Labs, we believe useful technology can start with a small idea and grow into something that makes life better for more people. PrivXion is our first step: a practical tool built around privacy, care, and the freedom to focus on what matters.
As we grow, we hope to build more thoughtful tools and dedicate a portion of our progress to humanitarian causes. We’ll share those plans and their progress as they take shape.
Because every person deserves the chance to create, connect, and move forward with confidence. This is our spark. And with you, it can become something greater.
PrivXion. Crafted for quiet protection. Built with a wider purpose.

06 / PRIVACY MODE

Privacy by design, explained plainly
Your privacy
is our top priority.
PrivXion is built to handle your session on your device. Here’s what that means in practice.
Your passcode isn’t stored in plaintext.
A salted PBKDF2 verifier is used for local passcode checks.
Your session data stays on your device.
Tab destinations are handled locally to lock and restore your browsing session.
No extension account, ads, or telemetry service.
The extension does not use an account, subscription, advertising, or telemetry service; website accounts are separate.
Website content isn’t sent to PrivXion servers.
The current build does not transmit your browsing history, cookies, page content, or passcodes to PrivXion servers.
PERMISSION TRANSPARENCYCURRENT SCOPE
Why PrivXion needs browser permissions.
PrivXion uses these permissions to lock supported web tabs, apply your chosen safeguards, and restore your session. They are the permissions requested by the current extension build:
STORAGE LIMIT
Session-restoration data is encrypted, but its encryption key is stored in the same Chrome profile. This helps protect the stored data, but not from someone with direct access to your profile. PrivXion also cannot prevent a device owner from disabling the extension.
Good questions
Before you
make it yours.
Clear answers about the current development build and planned release.
Which browsers does PrivXion support?
PrivXion is built for Google Chrome using Manifest V3. Confirm compatibility with your Chrome version in the Chrome Web Store listing once it is published.
When will PrivXion be available?
PrivXion is coming soon. Legal compliance work and the Chrome Web Store submission and review process are in progress. Installation and purchases will remain closed until those steps are complete.
Can I purchase PrivXion now?
Not yet. No live checkout is active. Purchase details will be published after release readiness and Chrome Web Store approval are complete.
Does PrivXion work with other browsers?
PrivXion is designed and supported exclusively for Google Chrome. Other browsers are not supported, even if they can install Chromium extensions.
Does PrivXion collect or upload my browsing data?
The current build has no telemetry or advertising service. It processes tab destinations locally to provide locking and restoration, and does not transmit browsing history, cookies, page content, or passcodes to PrivXion servers. Read the full privacy policy.
What happens to my tabs when I unlock?
After your passcode or recovery key is accepted, PrivXion restores supported tabs to their saved destinations. Replacing pages can discard unsaved page state, so save your work before locking when needed.
Does PrivXion replace my computer’s lock screen?
No. PrivXion helps deter casual access to supported tabs while you step away. It does not encrypt website sessions, secure your operating-system account, or prevent the browser owner from disabling or removing the extension.
