The 2018 free privacy tools starter kit

April 30, 2018 * Eugene Belinski

The following is a list of free tools I recommend for protecting your privacy online from advertisers, your ISP, social media companies, and others. For a broader discussion on privacy, check out my 2016 talk at Open Twin Cities.

TutaNota: A privacy-conscious email provider based in Germany, a country with stronger data privacy laws than the US. The free plan gets you a [email protected] address with 1 GB of storage. Unlike Gmail, TutaNota cannot scan your emails to display targeted ads, because your emails on TutaNota servers are encrypted at rest. (See limitations.)

ProtonMail: A more well known privacy-conscious email provider based in Switzerland, protected by Swiss privacy laws. The free plan gets you your own [email protected] address with 500 MB of storage, but all of your sent emails have a required "Sent with ProtonMail" signature. The paid plan is about $60 per year. (See limitations.)

Note-taking

Standard Notes: A cross-platform note-taking app with cloud storage. Unlike iCloud Notes and Google Keep, no one can read them except you. Their mobile apps are fine, but the desktop app needs some improvement. The free plan is more than enough for most people. I have found that the Extended plan ($35/year) doesn't really improve the desktop app, so it's not worth the money.
Messaging

Signal: A messaging app so secure that it's recommended by Edward Snowden. Available for iOS and Android. You can use it to send messages, group messages, calls, and video calls, which are always end-to-end encrypted, so they can't be read by anyone else.
Operating systems

Tails: A privacy and anonymity-focused operating system. Typically, Tails is installed on an external USB drive, and run on a computer, without replacing or affecting the OS inside the computer. Tails is a Linux OS, so there's a bit of a learning curve. All internet usage on Tails is routed through Tor. It's like the Tor Browser, but for the entire OS. More information can be found here.

LineageOS: An operating system for Android phones that is free and open-source. Combined with microG, it's worth trying out if you have a compatible device.

Web browsing

Tor Browser: The most secure web browser, Tor Browser routes all your traffic through the Tor Network. This means that your ISP can't tell what you're browsing, and the websites you visit will not necessarily know who you are. However, Tor Browser is not all you need to browse anonymously.

Firefox: For more standard web browsing, Firefox is the most popular free and open-source web browser. Unlike Chrome, it won't scan your files. Firefox is FOSS software developed by Mozilla, a non-profit organization.

Browser extensions

uBlock Origin: The most popular and most effective content blocker, blocking targeted ads, third-party trackers, malware, and more for Firefox, Chrome, Opera, and Edge. There is also a Safari experimental version. Beware of mixing up uBlock Origin with "uBlock", which is outdated.

Privacy Badger: A content blocker that is similar to uBlock Origin, but it only blocks trackers and ads that track you. Developed by the Electronic Frontier Foundation, it is available for Firefox, Chrome, and Opera.

HTTPS Everywhere: Another extension by EFF, HTTPS Everywhere redirects you from HTTP to HTTPS when it's available, increasing your privacy. Available for Firefox, Chrome, and Opera.

Decentraleyes: Helps avoid being tracked by third-party CDNs. Available for Firefox, Chrome, and Opera.

NoScript (Firefox only): For more advanced users, NoScript blocks all JavaScript scripts, and allows you to selectively whitelist scripts and websites.

File sharing

OnionShare: A tool that lets you securely and anonymously share a file of any size with someone, over the Tor Network. Available for Mac, Windows, and Linux.
Authentication

FreeOTP: A free and open-source authentication app for iOS and Android that is an alternative to Google Authenticator.

Authenticator by Matt Rubin (iOS only): A simple, beautiful authentication app that is an alternative to Google Authenticator. It is free, open-source, and never connects to the internet.
