Rethink DNS + Firewall is the easiest way to monitor app activity, circumvent Internet censorship, block ads and trackers on your Android device.

Android Firewall
Prevent apps from connecting to the Internet. A firewall can block any app connecting to the Internet over Wi-Fi or Mobile data. Since most forms of surveillance require the data to be sent over the network to a server, firewalling them effectively mitigates that threat (File Managers, Alarm Clock, Calculator are few such examples of apps that do not require any Internet access to function).

Content Blocking
Block ads, trackers, malware, and more. Messaging apps, for instance, can't be firewalled altogether, but can be, instead, blocked from accessing certain server endpoints of known ad-networks and trackers.

Anti-Censorship
Circumvent the most common way the Internet is censored. The app encrypts your requests sent to Domain Name System (DNS) resolver run by us with presence in 200+ locations worldwide. DNS resolvers are the address book of the Internet

Monitoring
Keep tabs on incoming and outgoing Internet traffic. The Rethink DNS + Firewall for Android keeps a log of connections every app makes and tracks its data use. Automated reports flag previously unknown or suspicious connections, and reveal the extent of surveillance.

SimpleX Chat - a private and encrypted messenger without any user IDs (not even random ones)! Make a private connection via link / QR code to send messages and make calls.

Unlike other messaging networks, SimpleX has no identifiers assigned to the users. It does not rely on phone numbers, domain-based addresses (like email or XMPP), usernames, public keys or even random numbers to identify its users — SimpleX server operators don't know how many people use their servers.

To deliver messages SimpleX uses pairwise anonymous addresses of unidirectional message queues, separate for received and sent messages, usually via different servers.

This design protects the privacy of who you are communicating with, hiding it from SimpleX network servers and from any observers. To hide your IP address from the servers, you can connect to SimpleX servers via Tor.

Technitium DNS Server is an open source authoritative as well as recursive DNS server that can be used for self hosting a DNS server for privacy & security. It works out-of-the-box with no or minimal configuration and provides a user friendly web console accessible using any modern web browser.

Nobody really bothers about domain name resolution since it works automatically behind the scenes and is complex to understand. Most computer software use the operating system's DNS resolver that usually query the configured ISP's DNS server using UDP protocol. This way works well for most people but, your ISP can see and control what website you can visit even when the website employ HTTPS security. Not only that, some ISPs can redirect, block or inject content into websites you visit even when you use a different DNS provider like Google DNS or Cloudflare DNS. Having Technitium DNS Server configured to use DNS-over-TLS, DNS-over-HTTPS, or DNS-over-QUIC encrypted DNS protocols with forwarders, these privacy & security issues can be mitigated very effectively.

Be it a home network or an organization's network, having a locally running DNS server gives you more insights into your network and helps to understand it better using the DNS logs and stats. It improves overall performance since most queries are served from the DNS cache making web sites load faster by not having to wait for frequent DNS resolutions. It also gives you an additional control over your network allowing you to block domain names network wide and also allows you to route your DNS traffic securely using encrypted DNS protocols.

“Terms of Service; Didn't Read” (short: ToS;DR) is a project started in June 2012 to help fix the “biggest lie on the web”: almost no one really reads the terms of service we agree to all the time.

Provides a simple way to see those terms and conditions elements that companies like to sneak away in an terms of service agreement that scrolls to the end of the universe.

What is IPFilter Updater?
It’s a small Windows application that will download and update an ipfilter list for use in Bit Torrent clients.

What Bit Torrent clients are supported?
Currently uTorrent, BitTorrent and qBittorrent are supported out of the box, but you can also configure other applications to pick up the downloaded list.

What is an ipfilter?
An ipfilter list is a simple (but usually very large) list of addresses and ranges of malicious peers that will transmit junk data (i.e. anti-P2P) or peers that may be intrusive on your net privacy.

Why do I need an ipfilter?
For privacy and more reliable peers

In comparison to popular messaging applications like Telegram, WhatsApp and Signal, Speek is by far the most secure way to converse. Speek is serverless, stores no metadata, requires no ID or phone number and all the messages are encrypted and routed via the Tor network.

All messages are end-to-end encrypted. The Speek client is creating a Tor hidden service on the client PC. The message is then routed via the Tor onion network to the receiver. This makes it possible that the IP addresses are never public and the users can stay anonymous. The users are identified with public keys. Each user can share their public key with others to add them to the contacts list.

The Invisible Internet Project (I2P) is a fully encrypted private network layer. It protects your activity and location. Every day people use the network to connect with people without worry of being tracked or their data being collected

I2P hides the server from the user and the user from the server. All I2P traffic is internal to the I2P network. Traffic inside I2P does not interact with the Internet directly. It is a layer on top of the Internet. It uses encrypted unidirectional tunnels between you and your peers. No one can see where traffic is coming from, where it is going, or what the contents are. Additionally I2P offers resistance to pattern recognition and blocking by censors. Because the network relies on peers to route traffic, location blocking is also reduced.

Orbot is a free VPN and proxy app that empowers other apps to use the internet more securely.
