I tried PCAPdroid recently and that seemed good

Holy fuck I hate HOA's/condo boards

Checked Alarm's privacy policy on their website... and it's kind of sketch. The big ol' "Privacy" link takes you to a page basically saying "We don't sell your info", which OK, cool.

However, scroll all the way to the bottom, and there's another privacy section. That one details what they do with info using their service.

Quick Bing AI summary:

RethinkDNS can show you where it's connecting via firewall logs and has PCAP

This doesn't show individual requests, but it shows the tracker libraries and permission demands: https://reports.exodus-privacy.eu.org/en/reports/com.alarm.alarmmobile.android/latest/

Does this app itself do the security surveiling or why does it need access to the camera, microphone, location, user movement, biometrics, contacts etc.?

Set up PCAPdroid with MITM.

For me I just refuse to use any app to access a service. I can tolerate websites.

Adguard can do that if you setting it in low level settings & activate HTTPS filtering for certain apps
