InviZible Pro

InviZible Pro bundles three privacy networks in one app, in its README’s words combining “the strengths of Tor, DNSCrypt, and Purple I2P”: Tor to hide your IP address from the sites you visit, DNSCrypt to encrypt the phone’s DNS lookups, and Purple I2P, a client for the separate I2P network. A firewall decides which apps may use which connections. The “Pro” is part of the name; there’s nothing to buy in this build.

Three ways to run it

From the project’s wiki:

• VPN mode, without root: InviZible sets up a local VPN on the phone and passes traffic to Tor, DNSCrypt and I2P. The wiki recommends it from Android 5.1; this is the mode the app picks when there is no root. The VPN code is based on NetGuard.
• Root mode: “uses iptables to redirect internet traffic to InviZible modules. In addition, the use of iptables can prevent unwanted data leaks.” Rules can apply to the whole device, single apps or single IP addresses, and you can share Tor or I2P over a Wi-Fi hotspot.
• Proxy mode: no VPN and no iptables. Apps that support a proxy, such as Firefox or Telegram, connect to InviZible’s local proxy.

What it does when you start it

• Tor and DNSCrypt start with the first tap; I2P stays off until you tick it. With Route All traffic through Tor, on by default, all TCP traffic goes through Tor and everything else is blocked, except sites and apps you add as exceptions. With it off, only what you add goes through Tor.
• Tor bridges for networks that block Tor: obfs4, Snowflake, WebTunnel, Conjure, meek and, new in 7.5.0, DNSTT. A list of default bridges is included, and you can request more from the Tor Project inside the app. SNI spoofing is an option when Tor connections are blocked.
• DNSCrypt uses eight servers by default, several of which filter ads and malware: AdGuard DNS, Control D’s malware and ad filter, dnsforge.de, LibreDNS without ads, Mullvad, and a family-safe filtering server hosted at Scaleway. Mullvad has announced it will shut that service down on 2 November 2026; in September the developer wrote that it would have to be replaced. You can choose other servers from DNSCrypt’s public list, which the app downloads and checks against its signature.
• The firewall allows or blocks each app on Wi-Fi, mobile data, LAN and roaming. It works while DNSCrypt or Tor is running, or on its own.
• Quick Settings tiles for Tor and DNSCrypt, and an Android TV version.

One limitation the developer points out: DNS can’t be split per app on Android, so “all apps use Tor DNS if it is running, or DNSCrypt if it is running”, even apps you route outside Tor. In Root mode, IPv6 is blocked.

What goes online

Nothing until you press Start, apart from what you ask for. Then:

• Tor, DNSCrypt and I2P connect to their networks; DNSCrypt also refreshes its server list from the DNSCrypt project every three days.
• Connection checks, through Tor or directly, to see whether the modules work.
• Requesting bridges contacts the Tor Project’s bridge service when you ask.
• When I2P runs, its default settings let it relay some traffic for other I2P users.

This F-Droid build doesn’t check for app updates; F-Droid’s own app does that. There are no analytics or advertising libraries, and crash reports are only sent if you choose to e-mail one after a crash.

About this file

• This is F-Droid’s build of version 7.5.0, the stable release from 12 July 2026, added to F-Droid on 15 July and signed with F-Droid’s key. F-Droid built it from the developer’s v7.5.0-stable tag.
• 7.5.0 updated DNSCrypt to 2.1.16, Tor to 0.4.9.11 and Purple I2P to 2.60.0, added DNSTT bridges and shortened the start-up time after a reboot.
• It is the 64-bit ARM build. F-Droid has a separate build for 32-bit ARM phones and none for x86.
• InviZible also has a beta line, numbered 2.7, published under a different package name; it installs alongside this one.
• The screenshots are the project’s own, from 2020; the interface has changed since.
• The 45.1 MB file runs on Android 5.0 and later and declares 16 permissions, for the VPN, network state, notifications, starting at boot if you enable it, and the list of apps for the firewall.
• InviZible Pro is licensed under the GPL-3.0 or later; Tor, Purple I2P and the Tor bridge programs are under BSD-style licences and dnscrypt-proxy under the ISC licence. The source of this version is at https://github.com/Gedsh/InviZible/tree/v7.5.0-stable, and F-Droid’s source archive of this build at https://f-droid.org/repo/pan.alexander.tordnscrypt.stable_27203_src.tar.gz.
• The APK also contains prebuilt BusyBox 1.31.1 and iptables 1.4.20 programs, used in Root mode, which are licensed under the GPL-2.0. Their source: BusyBox at https://github.com/meefik/busybox, and iptables at https://www.netfilter.org/projects/iptables/.

CPU types in this build: arm64-v8a (64-bit ARM, almost every phone since 2017).
