We respect your privacy. This app stores data locally in your browser (IndexedDB/LocalStorage) and does not send it to any server.
You can export/import state via Settings. To remove data, use the in‑app reset or clear your browser storage.
We do not collect personal data and do not use third‑party trackers.
There are no analytics counters or tracking scripts — the app does not need them.
All calculations are performed locally. In production, a Service Worker enables offline mode.
Keep your browser up to date and use secure devices.
You can install the app as a PWA on your device.
Once installed, it can work completely offline.
