Privacy Policy

Last updated: May 2026

The short version

ZeroTools does not collect, store, or transmit your personal data, files, or tool inputs. Period. Everything you do on ZeroTools happens locally in your browser.

How our tools work

When you use a tool on our platform (like the JSON formatter, Password generator, or QR scanner), the data you input is processed using client-side JavaScript. Your device's processor does all the work. We do not have backend servers that receive, process, or store your inputs.

Analytics and Tracking

We do not use invasive third-party trackers, retargeting pixels, or intrusive analytics platforms. If we monitor traffic, it is strictly anonymous, aggregated analytics to understand which tools are popular and ensure site uptime. We do not know who you are, what you generate, or what you encode.

Cookies

ZeroTools may use local storage or session storage within your browser to save your tool preferences (such as dark mode settings or favorite tools). This data never leaves your device and can be cleared at any time through your browser settings.
