Your rights

You have the right to ask us for a copy of your personal data; to correct, delete or restrict (stop any active) processing of your personal data; and to obtain the personal data you provide to us for a contract or with your consent in a structured, machine readable format, and to ask us to share (port) this data to another controller.

In addition, you can object to the processing of your personal data in some circumstances (in particular, where we don’t have to process the data to meet a contractual or other legal requirement).

These rights may be limited, for example if fulfilling your request would reveal personal data about another person, where they would infringe the rights of a third party (including our rights) or if you ask us to delete information which we are required by law to keep or have compelling legitimate interests in keeping. Relevant exemptions are included in the GDPR. We will inform you of relevant exemptions we rely upon when responding to any request you make.

To exercise any of these rights, or to obtain other information, such as a copy of a legitimate interests balancing test, you can get in touch with us using the details set out under the Section “Contact” below. If you have unresolved concerns, you have the right to complain to an EU data protection authority where you live, work or where you believe a breach may have occurred.

You have the right to ask us not to process your personal data for marketing purposes. We will usually inform you (before collecting your data) if we intend to use your data for such purposes or if we intend to disclose your information to any third party for such purposes. You can exercise your right to prevent such processing by checking certain boxes on the forms we use to collect your data. You can also exercise the right at any time by contacting us at

Please note that we may need to request specific information from you to help us confirm your identity and ensure your right to access your personal data (or to exercise any of your other rights). This is a security measure to ensure that personal data is not disclosed to any person who has no right to receive it. We may also contact you to ask for further information in relation to your request to speed up our response.

Which entity is my data controller, and which affiliates might my data be shared with?

The data controller for your information is Parity Technologies Limited of c/o IGNITION LAW Moray House, Floor 1, Moray House, 23-31 Great Titchfield Street, London, United Kingdom, WC1W 7PA.

Your data might be shared with our group company Parity Technologies Deutschland GmbH, Glogauer Str. 6, 10999, Berlin, Germany for recruiting purposes and for the management and execution of group functions.

How long will you retain my data?

Where you are a contributor, customer or a registered user, we will keep your information for the duration of any contractual relationship you have with us, and, to the extent permitted, after the end of that relationship for as long as necessary to perform the purposes set out in this notice.

Where we process personal data with your consent, we process the data until you ask us to stop and for a short period after this (to allow us to implement your requests). We also keep a record of the fact that you have asked us not to process your data indefinitely so that we can respect your request in future.

For data about your visits to our Sites and where we process personal data for Sites security purposes, we will retain this data for 12 months following your last visit to one of our Sites.

Data you provided to us in the course of your job application, or so as to be informed about jobs in the Substrate ecosystem will be kept for 6 months, if your application was not successful. If you enter into an employment relationship with us, the relevant information will be kept for the duration of the employment contract as part of your personnel file.

Laws may require us to hold certain information for specific periods. In other cases, we may retain data for an appropriate period after any relationship with you ends to protect itself from legal claims, or to administer its business.

How you protect my data

We strive to maintain the highest standards of security and Parity has put in place robust technical and organizational measures for the protection of your data in accordance with the current, general state of the art technologies, especially to protect the data against loss, falsification or access by unauthorized third persons. However the transmission of information via the internet is not completely secure. So, whilst we will do our best to protect your personal data, we cannot guarantee the security of your data transmitted to our Sites. Any transmission is at your own risk. Once we have received your personal data we will use strict procedures and security features to prevent unauthorized access.

Where we have given you (or where you have chosen) a password which enables you to access certain parts of our Sites, you are responsible for keeping this password confidential. We ask you not to share a password with anyone.
