What Definitive Healthcare LLC knows about you, and why removal matters
Definitive Healthcare LLC is required to register annually with the California Privacy Protection Agency under the state's data broker law (Cal. Civ. Code § 1798.99.80). Registration is a legal acknowledgment that the company knowingly collects and sells or licenses personal information about California residents with whom it has no direct relationship. That same status is what gives you clear standing to demand deletion: a registered broker cannot claim it has no record of you simply because you have never been its customer.
According to its own 2024 registry filing, Definitive Healthcare LLC collects names, birth dates, emails, phone numbers, ad IDs.
Definitive Healthcare LLC also disclosed that, in 2024, it shared or sold consumer data to the U.S. federal government, and other state governments. Every downstream recipient is another copy of your information outside your control, which is the practical reason to remove yourself at the source rather than chasing each buyer individually. Deleting your record at Definitive Healthcare LLC cuts off the supply before it propagates further.
Definitive Healthcare LLC's 2024 disclosure reports 692 deletion requests, of which it complied with 660 (95%) and denied 32 (5%). Its median response time was a relatively quick 3 days, well inside the 45-day legal deadline.
The fastest route is Definitive Healthcare LLC's dedicated privacy-request portal, where you can submit a deletion request directly. If the form is slow, broken, or asks for more identification than you are comfortable providing, you can fall back to a written request to privacy@definitivehc.com citing your CCPA deletion right. OfflistMe can pre-fill that email for you so the legal citation and required details are already in place: you review it and send it from your own inbox.
