Is SimpleLogin by Proton: Secure Email Aliases safe?
SimpleLogin by Proton lets any page trigger alias creation and read the generated alias from its email input.
The extension injects a SimpleLogin button beside email fields on HTTP and HTTPS pages. A page can trigger that button, causing the extension to send the page URL's hostname to SimpleLogin and write the returned alias into the page-owned input where the page can read it.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 1 hostname
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data
Destinations our analysis observed SimpleLogin contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
