Warning: Apple iOS devices are affected by PRISM. Even using the software tools we recommend here, your privacy may be compromised by iOS itself. The operating system of any device can unfortunately lever out any privacy protection that a program tries to offer you. The latter has to run in the confines of the OS after all. We strongly recommend replacing your iOS device with an Android-compatible device running Replicant.
Google Public DNS permanently logs your ISP and location information for analysis. Your IP address is also stored for 24 hours.

“Off-the-Record Messaging, commonly referred to as OTR, is a cryptographic protocol that provides strong encryption for instant messaging conversations. OTR uses a combination of the AES symmetric-key algorithm, the Diffie–Hellman key exchange, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides perfect forward secrecy and malleable encryption.
The primary motivation behind the protocol was providing deniability for the conversation participants while keeping conversations confidential, like a private conversation in real life, or off the record in journalism sourcing.”

What is an MTA?
“Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. An MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol.
The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.”
A mesh network is a decentralized peer-to-peer network, with user-controlled physical links that are usually wireless.
“Mesh networking (topology) is a type of networking where each node must not only capture and disseminate its own data, but also serve as a relay for other nodes, that is, it must collaborate to propagate the data in the network.”

Try to use Tor Browser for all of your web surfing. It will offer you far better anonymity than any other browser. Make sure to learn the basics of Tor before using it. If the site you want to visit will not work in Tor Browser, try Firefox intead, but realize these browsers do not anonymize your ip by default.
Tor Browser notes: Using Tor Browser to sign into websites that contain your real ID is counterproductive, and may trip the site's fraud protection. Make sure to check for HTTPS before signing in to a website through Tor. Signing into HTTP websites can result in your ID being captured by a Tor exit node.
Firefox notes: This browser uses Google search by default: replace it with a more private alternative. Iceweasel is a rebranded version of Firefox that does not have to follow Mozilla Trademark Policy.
