The play store page for this app states:
- No data shared with third parties
- This app may collect these data types
- Data isn’t encrypted
- You can request that data be deleted
I just checked the BM2 app (subject of the blog post series) and they have updated with the similar detail [2], updated on the 25th of June 2023, although they say the data is encrypted - will need to verify if this is the case with the latest release. It also still says data not sent to any third party. If they still use the Alibaba AMap SDK - then that's a third party.
The Apple app store also now discloses location data is being sent [3]
I'd like to think my research / blog posts put pressure on them to start being honest with their customers.
This doesn't excuse them though. A battery monitor does not need to know your location.
