This modal pops up when you enable Bouncer on iOS 18:
"The developer of 'Bouncer' will receive the text, attachments, and sender information in SMS and MMS messages from senders not in your Contacts. Messages may include personal or sensitive information like bank verification codes."
> For privacy reasons, the system handles all communication with your associated server; your Message Filter app extension can’t access the network directly.
Thanks for the documentation link, I was uneasy about using this type of extension.
They do, but it's important to realize here that there is, in fact, a small demographic who actually want to get that political spam. So messages like that are going to get through the automated spam filter.
I suppose they could bundle a more advanced rules-based system, but since there's an API for user apps to do it, why not leave the job up to them?
It uses iOS’s SMS Filtering framework, which does the filtering in a privacy-preserving way: https://developer.apple.com/documentation/sms_and_call_repor...
