The classroom corner

Classroom timer and work cycles

A timer that counts what is left from a fixed end instant, never by adding up ticks: that is the only way not to drift when the browser slows its timers down, which it does to save power and documents openly.

No input: this tool counts

This tool asks for no file and no text: it COUNTS, using your device's clock. Set the duration just below, then start it.

What this tool builds is never transmitted

The result is built inside your browser, on your device, and it is sent nowhere. Nobody but you ever sees it, and nothing is kept once the tab is closed. No server ever had to know it.

Checkable in ten seconds, without taking our word for it:

  1. Open your browser's inspector: the F12 key (or Ctrl+Shift+I, or Cmd+Option+I on a Mac).
  2. Go to the “Network” tab, then clear the list.
  3. Run the tool on this page, as many times as you like. The list stays empty: no request goes out.
  4. To go further: cut your connection, and do it again. The tool still builds.

This absence of requests is also checked BY MACHINE before every release: a lock drives a real browser, processes a real file, and refuses to publish if a single byte goes out.

InstructionsHow it works

This tool takes neither a file nor a text. All it needs is your device's clock, and it writes nothing: not on a server, not on your machine. Closing the tab erases everything, settings included.
