If it's dumping Contact Tracing Data in the system logs it's in the kernel.
Contact Tracing is an Android Operating System Feature
At the start of the pandemic, Apple and Google scrambled to enable covid-19 contact tracing on their respective smartphone operating systems. The feature, which works across iOS and Android...Both companies had promised that pertinent data collected from the features, like where you’d been and who you’d passed by, would remain relatively anonymous and that only public health agencies would have access to that information.
Apps like the Samsung Browser and Motorola’s MotoCare have grandfathered access to system logs for analytics and crash reports, which is where the data is stored.
The contact-tracing tools work by exchanging anonymized Bluetooth signals with other phones. Those signals change every 15 minutes so that individual users aren’t identifiable, created from a key that’s refreshed every 24 hours. The signals generated and received by an Android phone’s contact tracing are then saved into the device system logs.

When two users are in close proximity, BLE (Always on 24/7), their devices exchange anonymous identifiers (Contact Tracing) that change daily.
Google and Apple released an API for public health agencies to create contact tracing apps. This was accompanied by AN OS UPDATE (Meaning it's a built in feature) to support these applications.
Contact tracing features are available on devices running Android 6.0 Marshmallow and newer, ensuring that even older devices can benefit from this functionality.
Apple and Google's contact tracing system is designed to keep data on users' devices to protect privacy. The system uses Bluetooth technology to log encounters.
Can an app on a phone that spoofs "infections" locate users?
