There is a program that shows whether you are being spied on
Define “spied” first please
mobile phone tapping
No, not really, they just record in your TelCo data center
Better use an encrypted messaging app with calls, like Conversations 
I think he might be talking about a spyware-detector (which could also be seen as mobile phone tapping).
Guess we need A LOT more information.
Hello again . I use a mobile phone without sim cards only from wifi
But somehow the data is leaking, where I live, freedom of speech does not exist, I know in many cases when a mobile phone was tapped, maybe there is some program that detects whether there is a leak
Netguard, block all, manage system apps, enable filtering, allow some?
maybe you have a link AÄŚIU
F-Droid - search - Netguard?
Also get a hosts list to add from GitHub - StevenBlack/hosts: đź”’ Consolidating and extending hosts files from several well-curated sources. Optionally pick extensions for porn, social media, and other categories.
If you mean you want links for spyware detectors (as opposed to blockers, there are also many apps in that category), maybe some of these?

There are many websites devoted to the topic of eliminating possible leaks. Try your favorite search engine for topics like “android debloat”, “android privacy tools” , “how to degoogle android”, etc.
