About Privacy Toolkit
Our Mission
Privacy Toolkit provides free, independent privacy testing tools that help you understand how you're being tracked online and what you can do about it. Every tool runs 100% client-side in your browser — we don't collect, store, or transmit your data.
How We're Different
No accounts. You never need to sign up or log in to use any tool.
No server processing. Your passwords, emails, photos, and browsing data stay in your browser. We use client-side JavaScript exclusively — no data is sent to our servers because we don't have any servers to send it to.
No tracking. We don't use analytics, fingerprinting, or behavioral tracking. We practice what we preach.
Independent reviews. Our website privacy reviews use a transparent methodology with cited sources. We're not paid by any company to give favorable ratings.
Revenue & Transparency
Privacy Toolkit is supported by display advertising and affiliate partnerships with VPN and security products. When we recommend a product and you purchase through our link, we may earn a commission at no extra cost to you. Affiliate relationships never influence our privacy risk ratings or tool results — those are based on documented facts and our published methodology.
