ktmouk is an independent software publisher whose open-source project Hackaru addresses the growing need for privacy-first time tracking across personal and professional workflows. Hackaru is conceived as a lightweight, cross-platform desktop companion that unobtrusively logs hours spent on documents, websites, and applications, then visualizes the data through straightforward charts and CSV exports. Typical users include freelancers who must invoice accurately, remote teams that follow agile sprints, students who want to analyze study patterns, and anyone experimenting with personal productivity systems such as Pomodoro or GTD. Because the entire database remains local by default, organizations with strict compliance policies or individuals wary of cloud exposure can adopt the tool without lengthy security reviews. The interface is deliberately minimal: a system-tray timer starts and stops tasks, auto-complete speeds up project tagging, and idle detection prompts users to discard or keep away-time. Despite its simplicity, Hackaru supports flexible categorization, keyboard shortcuts, dark themes, and webhook integration for those who wish to push summaries to external services. ktmouk maintains the repository on GitHub, publishes signed binaries for Windows, and welcomes pull requests that refine performance or extend export formats. Hackaru is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest release, and can be queued alongside other applications for convenient batch installation.
