100% CLIENT-SIDE DATA PRIVACY GUARANTEE

Apps Built for Privacy.
Powered by Your Browser Sandbox.

We design developer tools and utilities that execute entirely inside your browser's client tab. We have zero server databases, collect zero telemetry, and never sell your data.

Telemetry Leak Shield

Because our application lacks outbound networking code for files, it is physically impossible for we or any third-party to steal or monetize your data.

Our Anti-Data Manifesto

Why we refuse to build cloud-based developer databases.

We Believe Data is a Liability

Standard utilities ask you to paste private logs, security tokens, or customer databases into textareas that sync to remote cloud instances. In contrast, we believe user data is a severe security liability to hold. By not collecting your data in the first place, we eliminate data leak risks entirely.

No Telemetry. No Advertising.

We do not track which documents you diff, how often you use our tools, or what directories you upload. There are zero tracking pixels or profile tracking cookies. Your session remains anonymous and secure within your browser boundary.

Your Data Cannot Be Sold

Standard privacy policies are filled with complex legal jargon allowing them to sell data under company reorganizations. Our policy is simple: **we cannot sell what we do not possess.** Since your code never leaves your browser, it remains strictly yours.

Auditable Network Logs

You do not have to take our word for it. Open your browser's Developer Tools (`F12`), head over to the **Network** tab, load a 50MB file and hit compare. You will notice that zero HTTP outbound server calls are triggered. You have complete audit control.

Flagship Application: TextDiff

Our core application, TextDiff, is a high-performance developer tool built to diff massive files instantly in the browser. It combines native performance with our absolute privacy guarantee:
