Roll history

Every roll you make is logged here — what you rolled, each individual die, and the total. It is useful when someone asks what you got two turns ago, and for checking that a run of bad luck really was just a run of bad luck.

Where this is stored

In your browser, and nowhere else. The log lives in localStorage under the key ediceroller:history, on the device you rolled on. It is never sent to a server — there is no server involved in rolling, since the site is a set of static files — so nobody else can see it, and it will not follow you to another device or another browser.

The most recent 50 rolls are kept and older ones drop off the end. Clearing your browser data clears this too, as does the Clear history button above. The privacy policy covers it alongside everything else stored locally.

Reading an entry

Each row shows the roll in dice notation, then the dice themselves, then the total. A roll of 4d6kh3 lists all four dice with the discarded one marked as dropped, so you can see the whole roll rather than just the number it produced. If the notation is unfamiliar, the guide to reading it takes about five minutes.

The dice themselves are drawn from a cryptographically secure random source, and the animation never decides the result —how it works sets out the method, with the code.
