Time Tracker sends nothing · GoEditPDF keeps your files in the browser · private AKS networking at Hager · LiDAR SLAM at Mirion
Most time trackers answer "where did my time go?" by uploading your activity to somebody's server. This one answers it without the upload — the diagram above is the entire data path, written out:
your activity (app, window, tab, idle) → timetracker.db (a local SQLite file you own) →
report.html (opens offline). No account, no server, no telemetry, so there is nothing to opt out of.
Beyond the diagram
- No manual timers — it tracks the foreground application, window title, browser tab and idle periods on its own
- Reports worth reading — daily and seven-day summaries, charts, categories and per-application totals
- Python,
pywin32andpsutil, with a test suite that runs in CI on every push - Windows installer on every release with a published SHA-256 checksum — and not code-signed, which the repository states plainly rather than hiding
Contributions are welcome — documentation, testing, bug fixes and Windows improvements are great places to start. The repository ships a contributing guide, a code of conduct, issue and pull request templates, and a test suite that runs in CI.

I am a software engineer, trained at JUNIA in Lille where I earned a French diplôme d'ingénieur carrying master's grade. I design and build AI SaaS platforms end to end — data model, backend, authentication, billing, CI/CD and interface — most of them on my own. CheckAI, a text classification service built on a RoBERTa model served through Hugging Face, is online today; Influence Persona, a multimodal content platform on Supabase and Stripe, is in launch preparation.
My engineering background is industrial before it was commercial. At Hager Group I built a proof of concept for deploying IoT APIs securely on Azure Kubernetes Service across three private virtual networks. At Mirion Technologies I built a real-time 2D LiDAR and SLAM mapping prototype on embedded Linux, with a Python operator interface. That work is why I care about systems that behave predictably under constraint and keep their data where it belongs — the thesis at the top of this page comes from it, not from marketing.
I keep an audited record of my own work. Several figures that used to sit on this page are gone, because the repositories behind them did not support the claim.
