FAQ

No. The history URL your game generates contains a temporary, read-only authkey that can only fetch pull records. It cannot log in, spend currency, or change anything. It also expires within roughly a day. PullDeck relays it once to fetch your history and never stores it.

Your history is stored in this browser. Optional cloud sync backs up pull records when enabled; full JSON backups also preserve manual history settings and target snapshots. Browser storage can be evicted or cleared, so download backups and use the storage protection control on Account & data.

Game APIs expose a limited history window that varies by game and version. Records outside that window need an older tracker export or backup. Import every banner or two; PullDeck merges records and detects non-overlapping live-import windows for review.

Authkeys last about 24 hours. Open the wish/warp/convene history screen in the game again, grab a fresh URL, and retry.

Calculations are isolated by game, UID, and banner. An unknown starting pity excludes the first five-star interval from luck statistics; you can enter a known starting state in the tracker. Character rate-ups are checked against historical banners. Light Cone and Genshin weapon featured rates are 75/25; WuWa featured weapons are guaranteed. Capturing Radiance and historical weapon target guarantees cannot be fully reconstructed from exported records. Unknown outcomes are labeled, and current Genshin targets can be recorded manually with an expiry.

Genshin: Character Event (both parallel banners), Weapon, Standard, and Chronicled. Star Rail: Character Event, Light Cone, and Standard. Wuthering Waves: Featured Resonator, Featured Weapon, Standard Resonator, and Standard Weapon.

No. PullDeck is an unofficial fan-made tool. All game names and assets belong to their respective owners.
