How pity works
Genshin Impact’s wish system runs on a counter: the more pulls without a five-star, the higher the chance one drops, until it becomes guaranteed. Alongside it runs the fifty-fifty rule — lose the banner five-star and the next one is guaranteed.
This page reads your history and tells you where you stand on both numbers right now, per banner, instead of leaving you to count or guess.
Where your data goes
A history file imported from your disk is parsed inside the browser and never uploaded. If you paste the in-game history link instead, it is passed once to the game’s own server to be read and comes straight back to you; nothing is stored on our side and nothing is logged.
What is kept stays in your browser under a single key, and you can clear it whenever you like from browser settings.
