 **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 Signal, insted of SMS** | Optional | SMS may be convinent, but it's  [no secure](https://www.fortherecordmag.com/archives/0315p25.shtml). [Signal](https://signal.org) is both the most secure and private option. [Silence](https://silence.im/) (encrypted SMS), [Threema](https://threema.ch), [Wire](https://wire.com/en/)(enterprise) and [Riot](https://about.riot.im/) are also encrypted.[iMessage](https://techcrunch.com/2014/02/27/apple-explains-exactly-how-secure-imessage-really-is/) and [WhatsApp](https://www.whatsapp.com) do claim to be [end-to-end-encrypted](https://signal.org/blog/whatsapp-complete/), but since they are not open source, verifying this is harder, and the private companies which own them (Apple and Facebook), have a questionable reputation when it comes to protecting users privacy. 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.
 **Consider running a custom ROM if you have an Android device** | Advanced | Your default OS tracks information about your usage, and app data, constantly. Consider a security-focused custom ROM, such as [Lineage](https://lineageos.org) or [CopperheadOS](https://copperhead.co/android/).
