Truecaller is massively popular in my country as well.

Before I knew any better, I was ignorant of the permissions and saw it as a worthy trade-off since my contact(s) will somehow end up there, if they weren't already. As all it takes is for someone else who has saved my number to download the app and give it permission.

Didn't give them much thought until I started seeing them buy advertisement spots in some of the local daily newspapers. They were getting greedy for more data. From that moment, I deleted my account and created a new account signed in only with a random Microsoft login and the app now lives in the work profile where there are no contacts.

The app will refuse to work until you grant it permission to make calls (read your IMEI pre-Android 10) and obviously read contacts permission. It is also quite intrusive. Coincidentally, the other app I found employing such dirty tactics by refusing to launch at all before being granted sensitive permissions is Whatsapp.
