PDF Reader That Is The Best For User Privacy?

I appreciate your reply!

This “Dangerzone” is still foreign to me. My primary concern with finding a PDF reader that was the best for preserving user privacy was that the PDF reader App would send telemetry back to someone on the Internet that would be able to see every PDF file a user opened.

I’m not concerned about opening a malicious PDF file, instead, I was concerned about the PDF reader App sending telemetry back to the PDF reader App author online.

We have recommended many apps that dont send telemetry (including Okular).

Which firewall?

I’ve been having endless problems with Windows 10’s inbuilt firewall so I’ve been looking to setup a 3rd party software firewall made by another company.

safing portmaster, though doesn’t work for windows ARM yet.

Probably don’t grant sensitive permissions to a random 3rd party firewall. While I agree with you that Windows firewall is pretty decrepit, it is much better to use the OS’ tools rather than rely on a third party. Probably look up a guide for this.

Is Portmaster still the way to go for a Windows firewall?

Well I use the built-in Windows anti-virus as it seems to work really well but the Windows firewall seems like it’s low on security features and reliability… :cry::cry::cry::cry:
