This package provides the modified version of the popular privacy tool, specifically the Proton VPN MOD APK. This release targets users who require advanced security features and global server access within the familiar Proton interface. By utilizing this modified file, users can access the application’s capabilities without the standard restrictions found in the basic version available on official app stores.
What This MOD Changes
The Proton VPN MOD APK provides a Premium Unlocked status for the application. This modification is designed to grant access to the full suite of features that are typically reserved for paid subscription tiers. Based on the provided source data, the modification unlocks the premium interface and functionality, allowing the user to interact with the service as a premium member. This includes access to the expanded server network and high-speed connection options that are generally restricted in the free version of the service.
Version and Compatibility
This specific build is based on version 5.19.78.0 (Internal Build 605197800) of the application. The package name is ch.protonvpn.android, and the file size is approximately 47 MB. To ensure the software runs correctly, your device must meet the following requirements:
- Minimum Operating System: Android 8.0 (API level 26) or higher.
- Storage Requirement: At least 47 MB of free space for the APK file.
- Installation Type: Single APK file (does not require OBB or additional data files).
Please be aware that this file uses a custom digital signature that differs from the version found on the Google Play Store. Because of this signature mismatch, the Proton VPN MOD APK cannot be installed as an update over an existing official installation. You must treat this as a standalone installation.
How to Install
To install this modified version on your Android device, follow these specific steps to ensure the package is accepted by the system:
- You must first uninstall any existing version of the app currently on your device. Since the MOD uses a different signature, the system will prevent the installation if the official version is still present.
- Open your device settings and navigate to the Security or Privacy section.
- Enable the option to “Install Apps from Unknown Sources” for your mobile browser or file manager.
- Locate the downloaded file named Proton-VPN-v5.19.78.0-MOD-thinkkers.com.apk in your storage.
- Tap the file to begin the installation process and follow the on-screen prompts.
- Once the installation is complete, you can open the app and access the unlocked features.
How This Compares to the Original Release
This version is built directly upon the official 5.19.78.0 release, meaning it retains the core UI and security protocols of the original developer’s build. The primary difference lies in the removal of subscription checks, resulting in the Premium Unlocked status. While the original release requires a monthly or yearly fee to access high-speed servers and advanced security tools, this MOD enables those features by default. Users will find the same settings menu and protocol options as the official version, but without the prompts to upgrade their account.
About Proton VPN
Proton VPN is the brainchild of the creators of Proton Mail, the world’s largest encrypted email service. As a complement to that service, Proton VPN aims to defend journalists, activists, and regular internet users from surveillance and censorship online. Proton VPN is unique in its approach from other Virtual Private Network services. As opposed to a focus on marketing, they concentrate on establishing themselves as a service that is transparent and supportive of privacy.
An important part of their service is the combination of where they are located and the laws that overlap them. Being in Geneva, Switzerland, provides users of the service with the privilege of one of the strongest privacy laws in the world. Switzerland does not align with the 5-Eyes or 14-Eyes alliances. This means that the company is protected from being forced to collaborate with foreign intelligence to spy or hand over data. This strong legal framework is used to a great advantage when it comes to service adoption for users who care about their data sovereignty and anonymity.
Being devoted to the “no-logs policy” means that the service does not collect logs of the users’ activity or connection data. When authorities approach the service for information about a user’s data, the service still stands behind its belief that it does not collect any data. The service backs up its commitment to privacy by undergoing independent security audits. The source code behind the service’s applications is open to the community to review, ultimately providing additional support and trust behind the service.
The service provides some advanced features to secure traffic on the open Internet. One of such features is Secure Core. Most VPNs have a weak spot where, if the exit server is monitored, the entire service can be compromised. To mitigate this risk, the service is able to route user traffic through multiple servers before leaving the network. To further strengthen this feature, Secure Core servers are located in Swiss, Icelandic, and Swedish data centers, which are all privacy friendly. Even if an attacker logs the final exit server in the network, they are still not able to determine a user’s true IP and location.
One of the core features is NetShield. This is designed as a DNS filter for malware blocking, advertisement blocking, and preventing trackers from following a user and creating a Web 2.0 profile. At the network level, this service provides a privacy gain with a decrease in data usage and an increase in browsing speed, especially on mobile devices, where ad-heavy websites reduce browsing speed.
The application supports multiple high performance protocols like OpenVPN, IKEv2, and WireGuard. WireGuard is particularly known to be fast, and thus, it is optimal for heavy use cases. For users in the most restricted access countries, the Stealth protocol is available. This protocol makes VPN traffic look like regular Internet traffic. This allows users to bypass firewalls and Deep Packet Inspection (DPI) which are the most common tools to block VPN traffic.
This service does more than security by also thinking about practical usability. To this effect, the developers of this service came up with a unique technology called VPN Accelerator. This technology increases normal VPN speeds by a staggering 400% by utilizing advanced techniques to reduce latency and bypassing the CPU limitations on VPN protocols. This makes the service usable for everything from privacy-focused browsing to streaming in high definition and even downloading large files.
For users that need constant protection, the app has a Kill Switch. This Kill Switch is a complementary measure to the built-in VPN. It disconnects the device from the internet if the VPN connection is lost. This prevents your IP address from being exposed to the internet. This also complements the service’s “Always-on” feature, which quickly establishes a secure connection if an interruption is encountered during the service.
The service has you covered for extreme networking needs, as well. With split tunneling, you can control which applications go inside the virtual private network tunneling interface and which go directly to the internet. This supports local resources that you need to access, like a printer or a local banking application, while still using a protected service for the rest of the connection. The service also has specialized servers including servers for Tor over VPN and P2P file transfer for additional protection and privacy for access to the Onion network.
This service was made for people who think privacy is a human right. Maybe you want to get around your local internet censorship, or maybe you just want to avoid having your internet service provider sell your browsing data. This service gives you professional grade encryption and a transparent operational model. By using a service built by a scientific community, you’re getting a service with integrity in the face of commercial pressures.
