Ohio's breach-notification obligations are set by Ohio Rev. Code 1349.19. This page summarises the deadline to notify affected residents, the attorney general notification threshold, whether a private right of action exists, and the penalties for late or missing notification.

Section OH.1
What the statute requires
Under Ohio Rev. Code 1349.19, a business that owns or licenses computerized personal information of Ohio residents must notify affected individuals within 45 days of discovery or notification of a breach.
Attorney general notification: no direct ag requirement (reporting agencies at more than 1,000 residents).
Section OH.2
What triggers notification
Like most US state statutes, notification is triggered by the unauthorized acquisition of unencrypted, unredacted computerized personal information that compromises its security, confidentiality, or integrity. Two concepts recur across the states and apply here.
Encryption safe harbor
Personal information that was encrypted, and where the encryption key was not also acquired, generally does not trigger notification. A stolen device with full-disk encryption is typically a non-event; an unencrypted record, or an encrypted record where the key was exposed alongside it, is a reportable breach.
Who must be notified
- [1] Affected Ohio residents: 45 days
- [2] Attorney general / state agency: no direct ag requirement (reporting agencies at more than 1,000 residents)
- [3] Consumer reporting agencies where the breach is large-scale
Section OH.3
Penalties and enforcement
Escalating civil penalties up to $10,000 per day for intentional or reckless non-compliance.
Private right of action: No. No direct individual lawsuits; AG may investigate under ORC 1349.191.

Section OH.4
How this compares to the strictest states
The strictest US deadlines are 30 days (California, Florida, Washington, Colorado, Maine, New York, New Jersey). The majority of states use a qualitative "without unreasonable delay" standard with no fixed day cap. Here is where Ohio sits.
Ohio imposes a fixed 45-day deadline. The strictest states cut this to 30 days, so Ohio sits 15 days behind the tightest regimes.
