What MarketShare Partners, LLC knows about you, and why removal matters
MarketShare Partners, 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, MarketShare Partners, LLC collects gender identity and expression, and names, birth dates, emails, phone numbers, ad IDs. One of these categories is classed as sensitive personal information under California law, which strengthens your case for both deletion and a limit on further sale or sharing.
MarketShare Partners, LLC did not report a volume of completed deletion requests for 2024, so there is no published track record to gauge its responsiveness. That makes a clearly worded, statute-citing request all the more important: cite Cal. Civ. Code § 1798.105 explicitly, keep a dated copy, and watch the 45-day clock so you have grounds to escalate to the California Privacy Protection Agency if the deadline passes in silence.
The fastest route is MarketShare Partners, 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 ns_privacy@transunion.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.
