TLDR: signal content in Apple notification can be retrieved even after signal app deletion.

I saw from this reddit thread: Signal messages retrieved from iPhone after uninstalling app. : signal

Referencing this news article: Pretti Killing May Affect ICE Prairieland "Antifa Cell" Terrorism Trial

The mention of signal is in court documents here: March 10: Federal Trial Day 12 - Support the Prairieland Defendants

Signal chat evidence from Sharp’s device (Exhibit 158):
Messages were recovered from Sharp’s phone through Apple’s internal notification storage — Signal had been removed, but incoming notifications were preserved in internal memory. Only incoming messages were captured (no outgoing).

Basically, they didn't do this:

(I'm on Android, so I don't know what the options look like in iOS, but they should be identical.)

Thank you internet stranger. I'm going to do this but fuck me if I can get my family to change their settings. They don't even know they can create a poll.

Don't ask me. I made all of you admins do I don't have to answer questions like how do I make a poll. Click the + button. Yeah. The one on your fucking screen right now.

No grandpa. We are not trying to figure out who is trans. No popop none of are naxies (I hope)

Anyway, click the +. Right there. That is how you create a poll.

They shouldn't have had to do this though.

there's a lot of things under fascism that shouldn't be needed

They are similar

You also don't need to do this on Android unless you are concerned about random people seeing the messages on your screen. Signal on Android does not use Google's push notification service

[–] Quill7513@slrpnk.net 1 points 28 minutes ago

as far as i know signal uses Google's notification service and if you want it to not you need to use Molly

Source? I'm pretty sure it falls back to a different mechanism when it doesn't find google services. And that is only on the version downloaded from their website.

You most certainly do. I looked in my notification history in my founding of signal messages.

Then I turned off my notification history.

It would be nice if Signal let you do this per conversation.

It's sort of a victim of its own success, I use it for both things that do and don't require opsec

[–] Quill7513@slrpnk.net 1 points 12 minutes ago

and on some level it's important for good opsec that things that don't require opsec be done with good opsec
