Warning: The Android operating system provided with phones and tablets is often modified with the addition of proprietary applications from Google or others and may compromise your privacy. We strongly recommend replacing it with [Replicant](../../projects/replicant (or compile Android from source for your device).
A must read: Mission Impossible: Hardening Android for Security and Privacy, by Mike Perry at The Tor Blog.
Why not MEGA? While MEGA is free as in beer, the software is proprietary code.
Why not SpiderOak? SpiderOak is proprietary software.
Why not Tarsnap? Tarsnap is partially proprietary and hosts your data on Amazon Web 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.“
Installing your own add-ons into Tor Browser is not recommended, as they may bypass Tor or otherwise harm your anonymity and privacy. Check the EFF's Panopticlick to see how trackable your browser configuration is by third parties.
If you're using a Firefox-based browser, you can safeguard your browsing habits and stop advertising companies from tracking you by installing uBlock Origin, Request Policy, and HTTPS Everywhere.
Why is Adblock Plus not recommended? Adblock Plus shows “acceptable ads” by default, which works against the purpose of the add-on. Either disable acceptable ads or use uBlock Origin instead.
Use a combination of Tor Browser and a free web browser of your choice to the surf the web.
Try to use Tor Browser as often as possible. Browsing is slower with Tor, but far more secure.
Note: Mozilla Firefox is technically not completely free software, as Mozilla recommends non-free add-ons on their website.
There is also a DuckDuckGo hidden service at 3g2upl4pq6kufc4m.onion for Tor users.
