PRIVACY POLICY

Your files stay in your browser

Kazakan Tools is designed to process the files and text you provide on your device. Tool inputs and results are not uploaded to our servers.

Processed on your device

Images, files, and text used in our tools are processed in your browser. We do not keep copies of them on our servers.

Aggregated usage counts

We send only the tool name and a general event, such as opening, starting, or completing it. The country and day are used to aggregate counts and see which tools are most used; we do not keep individual event histories or your file and text contents.

A small local preference

Your browser may save your theme preference locally so it remembers your choice. We do not use advertising cookies or build a browsing profile.

The site and its usage metrics run on Cloudflare. The provider may process technical connection data, such as an IP address, to deliver and protect the site under Cloudflare's Privacy Policy. We retain aggregate counts while they are useful for improving the tools. External sites, including the Kazakan store, follow their own privacy practices. Last updated: October 20, 2026.

How the Reaction Test Works

Click the box to start. The box will turn red (Wait). As soon as it turns green, click as fast as possible.

  • Clicking before it turns green triggers a False Start error.
  • Average human reaction time is typically between 200ms and 250ms.
  • Time is recorded with sub-millisecond precision via performance.now().
Privacy & Precision

All measurements are processed entirely on your device with zero network lag and no personal telemetry.
