Let the KYSS Team help you navigate the complexities of the web.
We help you
KEEP YOUR S**T SAFE – no matter what the web throws at you.

Our mission is to guide you through the chaos.
We focus on three key areas to keep you safe:
Protect your personal data
Use the right tools for secure browsing
Stay invisible online when needed
KYSS is a student project by privacy nerds and code enthusiasts with a passion for programming.
It’s educational, not commercial — all tools and services mentioned are unpaid and unsponsored,
simply because we believe good software should be shared, not sold.
And if money ever gets involved, we’ll throw a parade.
