What Should You Do Next?
- Read and save your notice. Keep the letter, any envelope, and any related emails or account alerts in one place. These documents may matter later.
- Review your accounts carefully. Check bank, credit, insurance, and tax-related records for activity you do not recognize. Because Social Security numbers and other sensitive identifiers were reportedly among the data types that may have been involved, early monitoring is important.
- Get your free credit reports and consider added protections. Review your reports for unfamiliar accounts or inquiries. You may also consider placing a fraud alert or security freeze with the major credit bureaus.
- Contact the company if you believe you were affected. The notice lists a dedicated response line at (844) 403-4528 for people who think they may have been impacted but did not receive a letter.

Your Legal Rights
People affected by a reported data incident may have legal rights, but those rights depend on the facts. Important issues can include what information was involved, what safeguards were in place, when notice was provided, and whether a person later experienced fraud, identity theft, or other measurable harm.
In some situations, affected individuals may seek recovery for out-of-pocket losses, time spent addressing the incident, or the cost of future protective measures. An attorney can help evaluate the available facts and explain possible next steps, but no result can be promised based on public reporting alone.
