Refer to use Pyarmor License
For the obfuscated scripts run in the customer’s device, Pyarmor has no any limitations, it’s totally controlled by users. Pyarmor only cares about build machine.
Each license has an unique number, the format is pyarmor-vax-xxxxxx, which x stands for a digital.
Each product requires one License No. So any product in global also has an unique number in Pyarmor world.
If user has many products, and has purchased one license for the first product. The second product could use first product license only if sale income of the second product less than 10x license fees. Once greater than 10x license fees, the second product need purchase its own license. It’s same to user’s other products.
One product in Pyarmor world means a product name and everything that makes up this name.
It includes all the devices to develop, build, debug, test product.
It also includes product current version, history versions and all the future versions.
One product may has several variants, each variant name is composed of product name plus feature name. As long as the proportion of the variable part is far less than that of the common part, they’re considered as “one product”.
Pyarmor License could be installed in many machines and devices which belong to licensed product. But there is limitation to be used at the same time.
In 24 hours only less than 100 devices can use one same Pyarmor License. Pyarmor License be used means use any feature of Pyarmor in one machine. Running obfuscated scripts generated by Pyarmor is not considered as Pyarmor License be used.
In details read EULA of Pyarmor
What’s one product
First of all, if not for sale, all the Python scripts are belong to one product “non-profits”.
Pyarmor is one product, it includes:
- Pyarmor basic, Pyarmor pro, and Pyarmor group
- pyarmor-webui which provides graphics interface for pyarmor.
- the order system of Pyarmor is a Django’s app running in cloud-server. This Django’s app also belongs to one product Pyarmor.
- the laptop used to develop Pyarmor, the PCs used to test Pyarmor, the cloud-server to serve order system of Pyarmor, all of them belong to one product Pyarmor.
- Pyarmor 7.x, Pyarmor 8.x and Pyarmor 9.x
Microsoft Office is not one product, because each product in Microsoft Office is functional independence. For example, Microsoft Word and Microsoft Excel belong to Microsoft Office, but they’re totally different.
Microsoft Word is one product, and Microsoft Word 2003，Word 2007 etc. are belong to one product Microsoft word.

5.4.1. Upgrading old license to Pyarmor Basic¶
First find the activation file pyarmor-regcode-xxxx.txt, which is sent to registration email when purchasing the license.
Next install Pyarmor 8.2+, according to new EULA of Pyarmor, each license is only for one product.
Assume this license will be used to obfuscate product XXX, run this command:
$ pyarmor reg -u -p "XXX" pyarmor-regcode-xxxx.txt
Check the upgraded license information:
$ pyarmor -v
After upgrade successfully, do not use activation file pyarmor-regcode-xxxx.txt again, it’s invalid now. A new registration file like pyarmor-regfile-xxxx.zip will be generated at the same time.
In other devices using this new registration file to register Pyarmor by this command:
$ pyarmor reg pyarmor-regfile-xxxx.zip
After successful registration, all obfuscations will automatically apply this license, and each obfuscation requires online license verification.
If old license is used by many products (mainly old personal license), only one product could be used after upgrading. For the others, it need purchase new license.
