Terms of Use

ZeroHour, by Logic Lab 406 LLC. Effective October 22, 2026.

By using ZeroHour you agree to these terms and to Apple's Standard End User License Agreement.

What ZeroHour is

ZeroHour turns public vulnerability data (CISA, NVD, Red Hat) into alerts for the products you choose. It is an information service, not professional security advice. Alerts can arrive late, be incomplete, or miss a vulnerability, and data from these sources can change. Always confirm with your vendor's own advisory before acting, and keep your own patching process.

No warranty

ZeroHour is provided "as is", without warranties of any kind. To the extent permitted by law, Logic Lab 406 LLC is not liable for any loss or damage arising from your use of, or reliance on, ZeroHour, including missed or delayed alerts.

ZeroHour Pro

ZeroHour Pro is an auto-renewing subscription, $4.99 per month or $39.99 per year in the US (prices vary by region), with a 7-day free trial for new subscribers. Payment is charged to your Apple Account when you confirm the purchase, or when the free trial ends. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel it in Settings › Apple Account › Subscriptions. Any unused part of a free trial is forfeited when you buy a subscription.

Fair use

Do not misuse the service, for example by scripting device sign-ups or overloading the server.

Trademarks

Product and vendor names in alerts belong to their owners. ZeroHour is not affiliated with or endorsed by CISA, NIST, Red Hat or any vendor.
