What is a 'token' ?

NETGuard is a pay-per-use service that use Token as currency

It means that you will only pay for what you use, you will not be charged monthly and pay for days when you want to obfuscate your file only once in a while. A token is a digital coin that you use in order to unlock the premium statu and then be able to select premium obfuscation techniques. That means you can select as many obfuscation features as you want, in the end you will always pay only one token.

Let's take an exemple with an imaginary program :

Filename	MD5	Token cost
myFile v1.0.0.0	4D1D4F2CF85A8F1DB9966B5196570ECB	1
myFile v1.0.0.0	4D1D4F2CF85A8F1DB9966B5196570ECB	0
myFile v1.0.0.0	4D1D4F2CF85A8F1DB9966B5196570ECB	0
myFile v1.0.0.1	D03EFD80B566869F7A526DC084B7E749	1
myFile v1.0.0.0	4D1D4F2CF85A8F1DB9966B5196570ECB	1

As you can see, if the las file you try to protect has its MD5 the same as the current file you want to obfuscate, the token cost is null. That is meant to easily fix compatibility issue with strong obfuscation features.

However, if you change / update the original file, its MD5 will change, that is why it will costs you a token as you can see in the array above.
