Stardust shares users' health data with RudderStack

Mozilla research found that period-tracking app Stardust shared sensitive users' health information with third-party analytics company RudderStack. The shared fields reportedly included birthdate, birth control type, reproductive goals, and specific symptoms, and records were tied to a persistent unique identifier rather than a name. Mozilla tested six period-tracking apps and found Stardust was the only one sharing sensitive health details with another company. RudderStack is said to be contractually prohibited from selling or using the data for its own purposes, but both U.S.-based companies can still receive law enforcement demands. TechCrunch previously reported in 2022 that Stardust's claim of end-to-end encryption was false after network-traffic analysis. Mozilla recommended Euki as an app that did not share health data off-device.

Lotame Unveils Spherical: Revolutionizing Data Portability and Activation

Lotame announced Spherical, a next-generation data platform designed to accelerate and extend first-party data. The platform aims to improve data portability and interoperability across brand and media owner tech stacks, enabling first-party data stored in data warehouses or CDPs to be activated in the madtech ecosystem amid privacy regulations and third-party cookie deprecation. At launch, Spherical integrates with leading CDPs including BlueConic, Meiro, mParticle, Rudderstack, Salesforce, Simon Data, Tealium, and Treasure Data, with plans to add more. Lotame CEO and founder Andy Monfried spoke at IAB’s Annual Leadership Meeting, noting industry pain around data accessibility and connectivity and arguing Spherical addresses those issues rather than symptoms. The platform supports activation across cookie-restricted, cookie-enabled, or authenticated environments, aiming to help brands unify, model, enrich, and activate customer data for engagement and growth.
