About This Breach

In August 2026, the digital health company Sharecare was the target of a ShinyHunters "pay or leak" extortion campaign. The group subsequently published data it claimed was taken from Sharecare's systems, containing 318k unique email addresses. Most of the data consisted of B2B sales and marketing records with names, physical addresses, phone numbers, job titles and employers. The data also included a small number of Brazilian health insurance plan members, including dates of birth, genders, marital statuses and CPF numbers (Brazilian taxpayer identification numbers).

Has your email been exposed in a breach?

I accept the Terms & Conditions*

1. Purpose: This tool checks whether your email address has appeared in publicly known data breaches via the Have I Been Pwned (HIBP) API.

2. Data Collection: Your email address is submitted to HIBP for breach lookup. If lead capture is enabled, your email may also be stored locally for service communication. Your IP address is recorded alongside it and used for rate limiting and abuse prevention. Past the daily limit of free checks, you will be asked for your email address and a 6-digit code we send to it; free checks are counted per IP address, stored in hashed form, for the day.

3. Third-Party Service: This tool relies on Have I Been Pwned (haveibeenpwned.com), an external service. Your email is transmitted to their API. Their privacy policy applies.

4. No Warranty: Results reflect data publicly known at the time of check. Absence does not guarantee your email has never been compromised; presence does not necessarily mean current risk.

5. Email Verification: Submitted addresses may be validated using automated checks (format, MX records, third-party verification services).

6. Data Retention & Privacy: Locally stored data is kept for 90 days and then deleted automatically. Breach monitoring and newsletter subscriptions are kept until you unsubscribe. We do not sell or share personal data with unrelated third parties.

7. Acceptable Use: This tool is provided for personal and business security awareness. Do not use it to check email addresses you do not own or are not authorized to verify.

8. Breach Monitoring (optional): You can only monitor an address you manage. If you turn it on and confirm with a code sent to that address, we store it with the list of breaches it already appears in, check it with HIBP periodically, and email you only if it appears in a new breach. Turning on monitoring also subscribes you to our newsletter, and unsubscribing from any of our emails stops the monitoring and deletes the record. To monitor the addresses of your staff or clients, contact us.

9. Changes: These terms may be updated at any time. Continued use constitutes acceptance.
