Filings
| Agency | Record date | People | In total | Days to notice | Links |
|---|---|---|---|---|---|
| HHS OCR HHS OCR | Feb 26, 2026 | 501 (total) | Record | ||

People is the count the filing gives, residents of the state unless marked total. Days to notice runs from the discovery date the letter states, or from the end of the breach window when no letter states one, to the date on the state's first record of the incident. "Over" marks a count past the days the state's statute allows for notice to residents. The statute's trigger is a question of fact, the days are arithmetic.
Notice timing, state by state
- 77 days from the end of the breach window (Nov 27, 2025, no discovery date in the letter) to the California record (Feb 12, 2026). Statute: 30 days from discovery or notification of the breach (Cal. Civ. Code § 1798.82).
The statutes
- California: 30 days to notify residents from discovery or notification of the breach, Cal. Civ. Code § 1798.82. Sample notice to the Attorney General when more than 500 Californians are notified, within 15 days of the consumer notice (effective 2026).
