What StackAdapt Inc. knows about you, and why removal matters
StackAdapt Inc. discloses that it handles precise geolocation: the data point California classifies as sensitive personal information. Location trails are among the most revealing categories a broker can hold: a stream of coordinates can expose where you live, where you work, the clinic or place of worship you visit, and the daily pattern of your movements. Because StackAdapt Inc. listed this category in its California Privacy Protection Agency registration, you can specifically invoke your right to limit the use and disclosure of sensitive personal information under Cal. Civ. Code § 1798.121 in addition to a full deletion request.
According to its own 2024 registry filing, StackAdapt Inc. collects precise geolocation, reproductive health data, and names, birth dates, emails, phone numbers, ad IDs. 2 of these categories are classed as sensitive personal information under California law, which strengthens your case for both deletion and a limit on further sale or sharing.
StackAdapt Inc.'s 2024 disclosure reports 5 deletion requests, of which it complied with 0 (0%) and denied 5 (100%). Its median response time was a relatively quick 2 days, well inside the 45-day legal deadline. The relatively high denial rate means it pays to send a precisely worded, statute-citing request rather than an informal one: denials often hinge on a request that failed identity verification or omitted the legal basis.
The fastest route is StackAdapt Inc.'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@stackadapt.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.
