What this measures
Saved runs live in local storage on this device. Nothing here is a public leaderboard.
How to read it
Save from the result on a test page. This section only reads that list. Export before you clear site data if you want a copy.
What it cannot do
The list is local to this browser profile. Another device, another browser, or cleared site data starts empty. Imported files are only as trustworthy as the file you chose.
Questions
Where are the scores stored?
In local storage in this browser. There is no account.
Can I compare with a friend?
Only if they send you an exported JSON file and you import it. There is no shared board.
What is the weighted score?
An average of numbers you type, with weights you type. It is not a standard PC score.
