About Kronolog

What it is

Kronolog is a minimal time tracker. Type what you're working on, press start, and the clock runs until you press stop. Picking an earlier task back up takes a single tap. Forgot to start or stop? Add the entry afterwards, or fix its times by long-pressing it in the list.

Share across devices

Open the menu (☰) to get a QR code and scan it on another device — that device joins your session instantly. Tasks and running timers stay in step across your phone, laptop, and tablet: start a task on one, and it's already running on the others.

Privacy

Your task names and times are encrypted in your browser before they leave your device. The encryption key exists only on your devices — it travels inside the QR code and never touches the server. All the server ever holds is ciphertext it can't read, so it can't see what you're working on. Sessions left untouched for a year are deleted automatically.
