Separate pity for each account and banner, featured guarantees, and clear uncertainty when your history is incomplete.
Is this safe?
Importing uses the same read-only history URL your game already generates. The authkey in it can only read pull history, expires within about a day, and is used in-flight only; PullDeck never stores it. Your password is never involved and nothing can act on your account. Read the full FAQ.
