KyuukeiChan – active-break reminders for Windows

KyuukeiChan counts 30 minutes of actual keyboard and mouse use, warns you a minute ahead, then slides a small always-on-top overlay into the corner: the character, one desk exercise with an animated diagram, one vocabulary word with pronunciation, and a 3-minute timer. Every third break is a 10-minute one. It also includes a 14-week gym plan with machine diagrams and a kg/reps log that never leaves your PC.

Loading the tool…

How it works

  1. Download the ZIP, unzip it anywhere (for example Documents\KyuukeiChan) and double-click INSTALAR.cmd. Accept the license once; it creates the Start-menu shortcuts and the autostart, and the pink 休 icon appears in the tray.
  2. Work normally. If you leave the keyboard and mouse for 3 minutes the counter pauses and restarts from zero when you come back, so an idle PC never nags you. One minute before each break a Windows notification shows the word that is coming and today's training.
  3. At the break, do the exercise shown, read (or listen to) the word, and press Enter for “Done” or Esc to postpone 5 minutes. Pick your deck (Japanese N1–N5, Chinese HSK, English, German, French, Italian, Portuguese), voice mode, hours and intervals in windows\config.json.

Why nothing is uploaded

Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.

Verify it yourself

  1. Open your browser’s developer tools (F12) and select the Network tab.
  2. Load your file and run the tool.
  3. The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.

Frequently asked questions

Is it free? Does it send any data?

Yes, it is free and open (MIT license) and it sends nothing anywhere: no account, no server, no telemetry. Breaks, weights and learned words are stored only on your PC. It is a set of readable PowerShell scripts, so you can inspect exactly what it does. The vocabulary decks come from open sources credited in THIRD-PARTY-LICENSES.txt.

Windows asks me to confirm when I run INSTALAR.cmd. Is that normal?

Yes. The package is not code-signed, so Windows may show a security prompt with “unknown publisher” the first time: choose Run. Nothing else is installed on the system; uninstall with DESINSTALAR.cmd and delete the folder you extracted.

Is this medical advice? Why 30 minutes?

No. The exercises and the training plan are general information, not medical or personal-training advice; consult a doctor before starting and stop if anything hurts. The 30-minute cadence follows the research on sedentary time: breaking up sitting every 30 minutes with 2–3 minutes of light activity improves glucose and blood-pressure responses. Use it at your own risk, as the license explains.
