Many Linux distributions offer to encrypt your hard drive when you install them. Ubuntu, PopOS, Elementary OS and more, they all have this option. If you did not enable encryption when you installed your system, you can encrypt your home folder or partition after the fact using ecrypt-utils, a command-line utility.

ENCRYPTION TUTORIAL: https://jumpcloud.com/blog/how-to-encrypt-ubuntu-20-04-desktop-post-installation

KDE has something called Plasma Vaults, which lets you create encrypted folders with a nice GUI, with the ability to set different passwords for each folder.

You probably also have an antivirus, your best option will be ClamAV (and ClamTK, its graphical interface). it detects Trojans, viruses, malware, etc., it is open source and completely free.

But if you want to restrict permissions for Flatpak apps, you need Flatseal. It's an app that will list all your flatpak apps and allow you to grant or remove permissions from them.

If you want the benefits of a sandbox but without using Flatpak apps, you can also run any app installed from a standard package or AppImage in a sandbox, using Firejail and Firetools, its graphical interface.

If you want to make sure that the apps or services you're running aren't doing anything weird with your Internet connection, then there's Portmaster from Safing. It's open source, free, and it lets you monitor every network request made by every part of your system and restrict them as you see fit. Oh, and it also has a system-wide ad blocker and trackers.

VPNs are a tool you can use to be more private online. I don't have any specific recommendations, but you can check the link I left in the description to TechLore's VPN table to find one that's private enough: https://techlore.tech/vpn.html

If you regularly use public or someone else's computers, you may want to use TAILS, an active USB drive, but with encrypted persistent storage.

Your web browser will also play an important role in your level of privacy on the Internet. If you prefer to stick with Chrome's rendering engine, then something like Brave will be much less intrusive and well configured by default, and if you don't want to encourage Google's monopoly on the Internet, then Firefox is also very private, a once disabled. opt-out telemetry in privacy and security settings.

You also have LibreWolf, which is Firefox without telemetry and with privacy-focused search engines out of the box.

Speaking of which, your search engine is also something you should look at when it comes to privacy. Google or Bing are simply NOT what you want for this. I personally use Ecosia as my default search engine. When Ecosia fails, I use the splash page, which basically contains Google's results, but with complete anonymization of all queries, so Google doesn't know who or where the query was made.

Bleachbit will allow you to delete cache files, cookies, internet history, temporary files, logs and more.

If you just want to completely delete a single file, there is GNOME File Shredder.

If you need to share some images but hide some information about them, blurring them with Gaussian blur is not enough, as it is now relatively easy to remove blur from an image. Obfuscate is a simple tool that allows you to hide information.
