The Period Tracker app by Simple Design claims to have over 150 million users and emphasizes local data storage for user privacy. During use, cycle data inputs were not transmitted over API, aligning with developer assertions that this data is stored locally. However, substantial third-party web traffic was observed, predominantly linked to Google Ads, which raised concerns about user consent visibility. Users are reportedly shown a consent dialog for personalized ads, though this was not experienced consistently during testing, suggesting potential issues in transparency regarding user advertising preferences.
The app does not appear to communicate with an API, and all period input data is stored locally on the device, ensuring user privacy.
Despite claims of user consent for personalized ads, our testing showed no consent dialog during the app setup, raising concerns about transparency.
Google Ads and third-party SDKs are heavily utilized in the app, indicating a significant focus on advertising traffic versus user cycle data tracking.
Users can adjust their advertising preferences under Settings, but inconsistent dialog appearances during setup raise questions about the consent process.
