02 — Your data stays in your browser
- Read on your deviceThe CSV is opened and analysed right here in the browser. It is never uploaded, and the Excel and PDF exports are created locally too.
- Saved only in this browserSo it's still there next time, the data and your Setup values are kept in this browser's storage. Other devices and browsers can't see it. Remove data deletes it.
- Shared only if you chooseShare packs the sessions into the link itself, after the #, which browsers don't send to the web server. Anyone you give the link to can see them.
One exception: if you pick a city for live fuel prices, only that city's name is sent to the fuel price service (infranode.dev). None of your charging data is.
