What contact information is available for you?
What's your overall profile?
HTTPS Everywhere - A Firefox, Chrome, and Opera extension that encrypts your communications with many major websites.
DuckDuckGo - A search engine that doesn't collect, store, or share any of your personal information
Brave - Blocks privacy-invasive ads & trackers. It blocks third-party data storage. It protects from browser fingerprinting. It upgrades every webpage possible to secure https connections. And it does all this by default.
Tor Browser - Anonymizes your web traffic using the Tor network, making it easy to protect your identity online. Caveats: Browsing the web over Tor is slower than on the regular Internet, and some major web services block Tor users.
NOTE: These apps might interfere with library database sites, and you might have to disable the app to use a database effectively.
