Everything below is yours. You can see exactly what a copy would contain, take that copy, and take all of it away — and none of those needs anybody's permission.
Counted from your own answer log rather than from a stored total, which is why every figure here can be checked against the pages that show it.
Nothing. Everything in this browser has reached your account.
Answers are kept as one row each — the question, the date, what you picked and whether it was right — rather than as a summary. It is what lets a phone and a browser that were both offline be put back together without either of them losing anything, and it is why a copy can hand you every answer instead of a total.
Four files, named in full, with the number of rows in each so you can check them against figures you have already seen.
Deleting is deleting. Nothing is archived, nothing is kept for thirty days, and nobody has to be asked.
The next page names what would go, by number, before it asks you anything — your answers, your run of days, your predicted score and your plan. It also says which of them are only in this browser and which are also in an account, because those are two different losses.
