Common questions

How much does the Greylock McKinnon Data Security Settlement pay?
Estimated payout: $0–$10,000. Actual amounts depend on how many valid claims are filed — most settlements divide a fixed fund pro rata, so a higher claim rate means a smaller individual check. An "up to" figure is a cap, not a guarantee.
What is the claim deadline for the Greylock McKinnon Data Security Settlement?
This settlement is closed to new claims — the deadline was June 9, 2025. Once a claim deadline passes you generally forfeit your share, even if you qualified.
Do I need proof of purchase for the Greylock McKinnon Data Security Settlement?
Yes. This settlement asks for documentation supporting your claim — a receipt, an account record, or the notice you were sent. Check the official settlement website for exactly which documents are accepted.
Is the Greylock McKinnon Data Security Settlement notice real, or a scam?
Claims are filed at gmadatasecuritysettlement.com. Filing a class action claim is always free — no legitimate settlement charges you to claim, and no administrator will ask for payment, a gift card, or your full Social Security number by email or text. If a notice asks for any of those, it is not from the administrator. When in doubt, ignore the link you were sent and go to the official settlement website directly.
When will payments from the Greylock McKinnon Data Security Settlement be sent?
Class action payouts typically take 12 to 24 months after the claim deadline, and longer if the settlement is appealed. The final approval hearing for this case is set for July 9, 2025; no payments can be issued before a settlement receives final approval.
