I have noticed some weird behavior on my smartphone that I can't explain myself.
I'm using Orbot application as proxy to route all of the phone's internet traffic through the Tor network.
When I search through browser "my ip" websites, results show Tor.
On the other hand, when I use other applications, ads in them are in my local language (very small number of speakers). I've noticed this mainly in ads in websites while browsing (Google browser and DuckDuckGo browser). Or when application is just wrapper of some website and again this website shows ad in my language (all websites are foreign). I think I have registered this in some non web browser applications on bottom where ads tend to be but not certain.
1 Sorry for adding this into comment, posted question as a guest...
Phone has set language as English and "region" is also different country
I've used phone originally for some time without proxy. Is it possible this is because of this and some identifying numbers of phone?
Google services do not have internet access. Permissions of these applications seems to be fine.
