According to signal facts all the have is your phone number and and the date you signed up for the service and the last day you connected to the server. IP address are not logged or stored the do t have access to it and signal has said this everytime the get a warrent for user data. So yes it is possible to have a secure service that doesn’t collect IP addresses but yes the do have some limited data so you are correct.
That is all they claim to store for later retrival*, which is not the same as what they would be able to capture in real-time and hand over to law-enforcement if forced to by a court (and they wouldn’t be able to tell you about it because of a gag-order).
*However this claim is contradicted by the source-code of their server (which they sometimes publish) which seems to store significantly more and of course this is assuming the code is indeed the same as the one they run on their servers, which is unclear.
Edit: and their servers run on AWS, so even if Signal itself doesn’t store the IP addresses, Amazon certainly could.
Very good and true point well said I agree with you on that good thing I am not important enough for it to be a issue lol or do anything illegal.
Passive data collection is an issue for me even though I am also not important. I do use Signal, but only with my true identity and with a few people I know from real life. When it comes to purely online communities, I compartmentalize my identities.
