If Go Ninja had your data

1. Look for Go Ninja’s own notice or letter: it should say what of yours was involved. Keep it.
2. Change your Go Ninja password, and the same password anywhere else you use it. Turn on two-step sign-in.
3. Expect scams that use your details: calls, texts or emails pretending to be Go Ninja, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
