 **Turn of connectivity features that aren’t being used** | Recommended | When you're not using WiFi, Bluetooth, NFC or anything else, turn those features off. These are commonly used to easily hack individuals.
 **Uninstall apps that you don’t need** | Recommended | Don’t have apps that your not using on your phone, as they can be collecting data in the background. Don’t install apps from non-legitimate sources, or apps with few reviews.
 **Don’t grant apps permissions that they don’t need** | Recommended | If an app doesn’t need access to your camera, don’t grant it access. Same with any features of your phone, be wary about what each app has access to.
+**Monitor Trackers** | Optional | A tracker is a piece of software meant to collect data about you or your usages. [εxodus](https://reports.exodus-privacy.eu.org/en/), is a great service, which lets you search for any app, by it's name, and see which trackers are embeded in it. They also have [an app](https://play.google.com/store/apps/details?id=org.eu.exodus_privacy.exodusprivacy), which shows trackers and permissions for all your installed apps.
 **Install a Firewall** | Optional | To prevent applications from leaking privacy-sensitive data, you can install a firewall app. This will make it easier to see and control which apps are making network requests in the background, and allow you to block specific apps from roaming when the screen is turned off. For Android, check out [NetGuard](https://www.netguard.me/), and for iOS there is [LockDown](https://apps.apple.com/us/app/lockdown-apps/id1469783711), both of which are open source. Alternatively there is [NoRootFirewall](https://play.google.com/store/apps/details?id=app.greyshirts.firewall) *Android*, [XPrivacy](https://github.com/M66B/XPrivacy) *Android (root required)*, [Fyde](https://apps.apple.com/us/app/fyde-mobile-security-access/) *iOS* and [Guardian Firewall](https://guardianapp.com/) *iOS*.
+**Use secure, privacy-respecting apps** | Optional | Mainstream apps have a reputation for not respecting the privacy of their users, and they're usually closed-source meaning vulnrabilities can be hidden. [Prism-Break](https://prism-break.org) maintains a list of better alternatives, see [Android](https://prism-break.org/en/categories/android/) and [iOS](https://prism-break.org/en/categories/ios/).
 **Don’t use SMS - Use E2E encrypted messaging apps** | Optional | [iMessage is secure](https://techcrunch.com/2014/02/27/apple-explains-exactly-how-secure-imessage-really-is/). For non-Apple users [Signal](https://signal.org) is the most secure option. As of late 2016 [WhatsApp](https://www.whatsapp.com) is also [end-to-end-encrypted using the Signal protocol](https://signal.org/blog/whatsapp-complete/). Keep in mind that although the transmission may be secured, messages can still be read if your, or your recipients' devices have been compromised.
 **Use a secure email provider** | Optional | Most email providers completely invade your privacy intercepting both messages sent and received. [ProtonMail](https://protonmail.com) is a secure email provider, that is open source and offers end-to-end encryption. There are alternative secure mail providers (such as [CounterMail](https://countermail.com), [HushMail](https://www.hushmail.com) and [MailFence](https://mailfence.com))- but [ProtonMail](https://protonmail.com) has both a clear interface and strong security record.
 **Avoid using your real phone number when signing up for an account or service** | Optional | Where possible, avoid giving out your real phone number while creating accounts online. You can create phone numbers using services such as [Google Voice](https://voice.google.com) or [Skype](https://www.skype.com/en/features/online-number/). For temporary usage you can use a service like [iNumbr](https://www.inumbr.com) that generates a phone number that forwards messages and calls to your main number.

 **Keep your OS up-to-date** | Recommended | Microsoft, Apple and Google release regular OS updates, which fix security risks. Always keep your device updated.
 **Consider Switching to Linux** | Optional | Linux is considerably [more secure](https://www.pcworld.com/article/202452/why_linux_is_more_secure_than_windows.html) than both OSX and Windows. Some distros are still more secure than others, so it’s worth choosing the right one to get a balance between security and convenience.
+**Avoid PC Apps that are not secure** | Optional | Mainstream apps have a reputation for not respecting the privacy of their users, and they're usually closed-source meaning vulnrabilities can be hidden. See here for compiled list of secure PC apps for [Windows](https://prism-break.org/en/categories/windows/), [OSX](https://prism-break.org/en/categories/macos/) and [Linux](https://prism-break.org/en/categories/gnu-linux/).
 **Use a Security-Focused Distro** | Advanced | [QubeOS](https://www.qubes-os.org/) is based on “security by compartmentalization”, where each app is sandboxed. [Whonix](https://www.whonix.org/) is based on Tor, so 100% of your traffic will go through the onion router. [Tails](https://tails.boum.org/) is a has no persistent memory, and is ideal if you don’t want to leave a trace on the device your booting from. [Subgraph](https://subgraph.com/) is an “adversary resistant computing platform”, but also surprisingly easy to use
 **Password protect your BIOS and drives** | Advanced | A BIOS or UEFI password helps to make an inexperienced hackers life a bit harder if they get a hold of your PC or hard drive, [here is a guide on how to do it](https://www.howtogeek.com/186235/how-to-secure-your-computer-with-a-bios-or-uefi-password/).
 **Canary Tokens** | Advanced | Network breaches happen, but the longer it takes for you to find out about it, the more damage is done. A canary token is like a hacker honeypot, something that looks appealing to them once they've gained access to your system. When they open the file, unknowingly to them, a script is run which will not only alert you of the breach, but also grab some of the hackers system details. [CanaryTokens.org](https://canarytokens.org/generate) and [BlueCloudDrive](https://blueclouddrive.com/generate) are excellent sites, that you can use to generate your tokens. Then just leave them somewhere prominent on your system. [Learn more](https://blog.thinkst.com/p/canarytokensorg-quick-free-detection.html) about canary tokens, or see [this guide](https://resources.infosecinstitute.com/how-to-protect-files-with-canary-tokens/) for details on how to create them yourself.
