We collect two different types of data: licensing data and telemetry data / error reporting.

### 2.1 Licensing <a href="#tix1levvvgj1" id="tix1levvvgj1"></a>

As part of our license verification process, to identify unique devices and users we collect information on the following hardware components to generate a unique identity key per device. The hardware components are:

* Motherboard
* Processor (CPU)
* Hard disks or other similar storage units.

We store the following data:

<table data-header-hidden><thead><tr><th width="314"></th><th></th></tr></thead><tbody><tr><td><strong>User first name, last name, and email address</strong></td><td>Used to identify the assignment of keys to individual users.</td></tr><tr><td><strong>User company name and job title</strong></td><td><p>Used to identify the company and job title of the user to which the license is assigned. Only collected in:</p><ul><li>Community Edition</li><li>Teams Edition - 14-Day Free Trial</li></ul></td></tr><tr><td><strong>License first activated</strong></td><td>Date and time</td></tr><tr><td><strong>License last checked</strong></td><td>Date and time</td></tr><tr><td><strong>External IP address</strong></td><td>x.xx.xxx.xxx</td></tr><tr><td><strong>Hardware ID</strong></td><td>This is a secure hash of a unique identifier used to distinguish between devices</td></tr><tr><td><strong>Number of times license activated</strong></td><td>x</td></tr></tbody></table>

The license management technology used by Diffblue is provided by [LicenseSpring](https://licensespring.com/). Please click here to see the[ LicenseSpring privacy notice](https://licensespring.com/privacy).
