CallonDoc, Inc. data breach

Clerk's notes

CallonDoc, Inc., a digital healthcare and telehealth platform operating in California, formally reported a security incident to state authorities in September 2026. This breach, which began in December 2025, involved unauthorized third-party access to the highly sensitive personal and medical data CallonDoc maintains for its patients.

The exposed information includes a comprehensive range of sensitive data categories. Affected individuals may have had their Full Name, Date of Birth, Social Security Number, Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Prescription Information, and Financial Account and Payment Details compromised.

Such a data compromise on a telehealth platform carries significant risks. The combination of personal identifiers like Social Security Numbers with medical and financial details creates a high potential for severe financial identity theft, medical identity theft, and fraudulent insurance claims, which can have long-lasting consequences for victims.

As a healthcare entity, CallonDoc, Inc. is subject to stringent federal and state regulations, including HIPAA and the California Confidentiality of Medical Information Act (CMIA). These laws mandate robust safeguards for patient data. A breach of this magnitude raises concerns regarding the company's adherence to its legal obligations to protect sensitive health information.

If you have received a data breach notification letter from CallonDoc, Inc., this confirms that your private information was involved in this security incident. These notifications are official acknowledgments that your data has been exposed to unauthorized parties.

Individuals impacted by this breach are encouraged to understand their legal standing. The exposure of sensitive personal and medical data, regardless of immediate financial harm, can be an actionable injury due to the heightened risk of future identity theft and privacy violations. Evaluating your case can clarify available options.
