The table above covers the FlowSmartly platform. This public website is smaller and simpler, so here is the complete, exact list of what it puts in your browser. It sets no cookies at all — it uses local storage, which is not sent with any network request. You can check every row of this in your browser's developer tools.

fs.consent.v1
Strictly necessary
Remembers the choice you made here, so we do not ask on every page.
12 months, then we ask again
fs.attribution.v1
Analytics
The channel, referrer and first page of your first visit, so we can tell which marketing actually works. First touch only — a later visit never overwrites it. The campaign and ad-click fields are kept only if you also allow Marketing.
Written only once you allow Analytics; removed the moment you withdraw
Until you make a choice, only the strictly necessary row exists. Anything measured before that point is held in memory and discarded if you decline — it is never written down and never sent. Withdrawing later removes the analytics row again, immediately.
Two things are deliberately absent from that list. The light, grey or dark appearance you pick on this site is not stored at all — it is held in memory for as long as the page is open and resets when you reload, so there is nothing on your device to clear. And fs.analytics.debug, which you may see if you have used our developer console, is only ever read by us and never written: it is a switch you set yourself to watch what would be sent.
