Your Period Tracker Is (Probably) Spying on You

A Mozilla-led audit found some period-tracking apps share sensitive reproductive health data with third parties.

Stardust ranked worst for privacy, sending health details and app identifiers to vendors like RudderStack and Facebook.

Euki stood out by keeping data on-device and offering stronger privacy controls.

The roundup also highlighted broader privacy and security moves, including EU and UK actions and U.S. sanctions on Russia’s FSB over a cyberattack.
