Recovery amounts and how to file
What triggers eligibility: your PII (Personally Identifiable Information) was in the breach. Notification letters usually go out, but not always to everyone affected. Settlement administrator sites let you search by email to confirm. Class Action Buddy indexes major breaches so you never miss a deadline.
