Privacy Notice
This notice was last updated on 26 July 2022. We may change this notice from time to time, so please check this page for updates.
We are committed to respecting your data privacy and we avoid collecting information from our products that could identify you as an individual wherever possible. Please note, however, that using our licensing feature does result in us collecting Personally Identifiable Information.
We are Diffblue Limited, AI for Code. We are a company registered in England and Wales number 09958102, with our registered office at Diffblue Ltd, 16c Worcester Place, Oxford, OX1 2JW, UK. We are the controller of the data described in this notice.
We collect two different types of data: licensing data and optional anonymous telemetry data / error reporting.
When activating community edition you may optionally enter your email address to receive product update notification emails containing information about what is new and expected in upcoming releases.
As part of our licensing, we need to collect information on the following hardware components to generate a unique identity key per device. This is to ensure that each occurrence of our product has its own licence. The hardware components are:
- Motherboard
- Processor (CPU)
- Hard disks or other similar storage units.
We store the following data:
User identifier | Optional; used to identify the assignment of keys to individual users |
Email address | Optional; used to provide software updates and license communications via email |
License first activated | Date and time |
License last checked | Date and time |
External IP address | x.xx.xxx.xxx |
Hardware ID | This is a secure hash of a unique identifier used to distinguish between devices |
Number of times license activated | X |
Diffblue collects optional, anonymous telemetry data about your usage of Diffblue products to improve them. The data is sent to Diffblue over an encrypted HTTPS connection. It is enabled by default and you can turn it off as described below, though we hope that you will agree to share the data to help us build a better product. We do not sell the data or make it available to third parties – it is only ever used internally at Diffblue.
Please note that if you migrate from a version with telemetry to a version without telemetry, it will be automatically turned off. If you migrate from a version without telemetry to a verison with telemetry, it will be enabled by default (and you can turn it off as described below).
Here's what we collect, with examples, and how it's used:
Data point | Example | Usage |
