ThunderVPN Review 2023

Table of Contents

ThunderVPN has been downloaded over 10 million times since it went live in 2017 and was developed by Signal Lab, coincidentally the same company that developed the increasingly popular Secure VPN.

Signal Lab mirrors a California-based register, which coincidentally (not really); California doesn’t allow storage of user data, making it the perfect nesting ground for VPN providers. The privacy policy does state that “we collect data about your IP, device, brand, location, and operating system,” but this data is completely deleted at the end of each session.

Why this company would record user data temporarily and then delete it is unclear. For users who want complete anonymity on the Internet, ThunderVPN is not suitable.

On its official website, the service claims to specialize in unblocking websites and various apps. However, after our own tests, we can confirm that this is not the case. Moreover, the developer does not inform users about the protocols and encryption methods used by its apps. In our tests, we were only unable to unlock BBC iPlayer, none of the other streaming platforms were bypassed. Last but not least, ThunderVPN does not unlock torrents.


The product doesn’t have too many features worth mentioning. However, it lists the following features.

  • Free forever
  • Unlimited bandwidth
  • No registration required
  • Global servers
  • No logging of user data

Speed Test

When using ThunderVPN, we saw a significant drop in speed across all available servers. When connecting to a nearby VPN server, we measured an average download speed of just 1.93 Mbps, which is nowhere near fast enough for reliable streaming, torrenting, or even casual browsing.

Here are the results of our latest speed tests.

  • Download speed without ThunderVPN: 52.2 Mbps
  • Download speed with ThunderVPN: 1.93 Mbps
  • With ThunderVPN, our download speed was reduced: 96%
  • This speed loss on local connections is pretty scary.

    In our test lab in the UK, we measured the average speed of ThunderVPN connections to different parts of the world. These are the results.

    • USA: 1.93 Mbit/s (download) and 32.66 Mbit/s (upload)
    • Germany: 1.94 Mbit/s (download) and 44.70 Mbit/s (upload)

    Thunder VPN is at least consistent, but consistently poor.

Pricing Plans


Yes, Thunder VPN is completely free, which is probably the most commendable thing about it in most people’s eyes. Not for me, and I’ll explain why.

Here at Open Developer, we are extremely skeptical of the concept of “free” VPN services. We condemn them in general. At the end of the day, providers have to make money somehow, and in the case of ThunderVPN, they seem to do so through in-app advertising.

Of course, there are other ways providers can make money by having lots of users using their service, and that’s something you should definitely investigate and make your own decision. At Open Developer, we advocate Internet security above all else and recommend paid VPN services for these reasons.

Server Locations

Thunder VPN Presents the choice of eight states that are accessible to link to Although it once included eight countries, including Japan, it has been discontinued. 

Its discontinuation is of utmost importance since the IP address of our connection with Japan is the one we would have registered.

In any case, ThunderVPN no longer tries to serve Asian users. The connection point to the east is Germany. This is a clearly Eurocentric list, with North America getting everyone out of the way.

We have seen connections in several countries. The Netherlands, for example, connects us regularly. They seem to have solved this problem, as our review was the first. However, Thunder VPN is not the most reliable.

In addition, there are no citywide options, except in the US, where there are western and eastern options.

These are countries, as you can see from the program.

  • Canada
  • France
  • Germany
  • Italy
  • Luxembourg
  • Netherlands
  • United Kingdom
  • United States of America

This is limited. We recommend using a VPN service like TunnelBear or even Avira VPN, which offer multiple (working) server locations.

Security and Encryption

After anonymity comes security, and in a way, security is related to the level of encryption of the VPN connection. Many VPN providers like to boast about their connection protocols and encryption because it’s their way of keeping their users safe!

Take the recent moves announced by NordVPN and IVPN regarding the WireGuard protocol as an example. This is one of the cornerstones of VPNs, and ThunderVPN avoids the issue altogether. No mention of the protocol, no mention of encryption.

Even the snippet of description in the Google Play Store is stolen from the internet and recycled. One shudders to think what else has been recycled.

Log Policy

If you want to remain anonymous and secure when using a VPN, your company should have a no-logging policy. So what is Thunder VPN policy?

The company claims to have no logging policy. The site says, “We do not log or track user data.” We did a little research and found that this is one of the shortest policies in the VPN world – and we’ve tested many VPNs.

The policy states that certain personal data is collected when you log into the site. This also confused us, as there is no way to register on the company’s website.

You are also not required to provide any information. So the privacy policy is confusing, and it really worries us if they are keeping track. This is especially true considering that the company lists the data it may collect when you use the app on Android.

This includes the following, among others.

  • IP addresses
  • Internet service provider
  • Operating system version
  • Application ID and version
  • Server location
  • How much data is used on a daily basis

Customer Support

Not only is there no live chat support on the official website, but there is also no corresponding FAQ page or help page.

As mentioned above, the only FAQ you can read is in the Thunder VPN Android app. However, you won’t get very far with these few questions. Therefore, this is a major drawback as you can easily encounter technical issues when using a VPN.

Frequently Asked Questions

What platforms does ThunderVPN work on?

At the moment only Android

Is there a desktop client?

Not at the moment.

Bottom Line

Thunder VPN leaves a lot to the imagination and feels very uncomfortable. There is little to no information about the type of encryption Thunder uses and how it protects.

Your privacy or identity. You can’t trust any VPN that you read about and don’t feel comfortable and secure. After taking a look at the website and the app in the Google Play Store, you’ll immediately realize that there’s a problem.

There is a lot of misinformation and types. You get the impression that someone put it together in an hour, which is not the sign of a product that offers security.
