Note regarding Blockchain Services

The Polkadot, Kusama and Substrate based blockchain clients written in the programming language Rust which Parity is involved in building and maintaining do not collect information from you. However, any information you publish onto a (public) blockchain like Ethereum, Kusama or Polkadot is public by design. Your use of a client and interaction with a blockchain like Ethereum, Polkadot or Kusama will lead you to interact with other network participants on those blockchains. You should note that where you do so those with whom you interact as well as other participants on those networks may be able to determine certain things about you through your use of those networks.

For what purposes do we use your data and what is the legal basis for this use?

We may use, collect and store your personal data for the reasons set out below and in doing so rely on the following legal bases:

  • As required by Parity to conduct our business and pursue our legitimate interests (legal basis: Art. 6 para. 1 s. 1 lit. f GDPR), in particular:
    • to notify you about changes to our service;
    • to administer our Sites and for internal operations, including troubleshooting and statistical purposes;

We have carried out balancing tests for all the data processing we carry out on the basis of our legitimate interests according to Art. 6 para. 1 s. 1 lit. f GDPR, which we have described above.

  • To fulfil a contract, or take steps linked to a contract, with you or your organisation (legal basis: Art. 6 para. 1 s. 1 lit. b GDPR). This includes:
    • to register you or your organisation as a customer or business partner;
    • to provide and administer services or solutions, as instructed by you or your organisation;
    • to process payments, billing and collection.

Where we need to collect personal data by law or in order to process your instructions or perform a contract we have with you and you fail to provide that data when requested, we may not be able to carry out your instructions or perform the contract we have or are trying to enter into with you. In this case, we may have to cancel our engagement or contract you have with us, but we will notify you if this is the case at the time.

  • Where you give us consent according to Art. 6 para. 1 s. 1 lit. a GDPR:
    • we or our carefully selected partners will send you direct marketing in relation to our relevant products and services, or other products and services provided by us, our Affiliates and carefully selected partners.

    • we place cookies and use similar technologies in accordance with our Cookies Policy below and the information provided to you when those technologies are used;

Wherever we rely on your consent, you will be able to withdraw that consent (Art. 7 para. 3 GDPR) at any time, although we may have other legal grounds for processing your data for other purposes, such as those set out above. In some cases, we are able to send you direct marketing without your consent, where we rely on our legitimate interests. Once we have received notification that you have withdrawn your consent, we will no longer process your information for the purpose(s) to which you originally consented unless there is no other legal ground for the processing.

You have the right to withdraw your consent for direct marketing, or profiling we carry out for direct marketing, at any time. You can do this by following the instructions in our communications where this is an electronic message, or by contacting us at [email protected].

We will also disclose your personal information to third parties:

  • In the event that we sell or buy any business or assets, in which case we will disclose your personal data to the prospective seller or buyer of such business or assets in compliance with applicable law.
  • If Parity Technologies Limited (and/or any of its Affiliates) or substantially all of its assets are acquired by a third party, in which case personal data held by it about its customers will be one of the transferred assets.

This includes exchanging information with other companies and organisations for the purposes of fraud protection and credit risk reduction.

International Transfers

The data that we collect from you may be transferred and stored by us or our service provider(s) outside the European Economic Area ("EEA"). It may also be processed by staff operating outside the EEA (such as the US) who works for us or for one of our suppliers.

Where information is transferred outside the EEA, and where this is to a stakeholder or vendor in a country that is not subject to an adequacy decision by the EU Commission, data is adequately protected by data protection agreements, EU Commission approved standard contractual clauses or a vendor's Processor Binding Corporate Rules. A copy of the relevant mechanism can be provided for your review on request to [email protected].

Our Sites may, from time to time, contain links to and from the websites of our partner networks, and affiliates. If you follow a link to any of these websites, please note that these websites have their own privacy policies and that we do not accept any responsibility or liability for these policies. Please check these policies before you submit any personal data to these websites.

Your rights

According to the GDPR, you may have the following rights pursuant to Art. 15-18 and 20-21 GDPR:

  • You may have the right to access your personal data and ask us for a copy of your personal data (Art. 15 GDPR); to correct, delete or restrict (stop any active) processing of your personal data (Art. 16-18 GDPR); 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 (Art. 20 GDPR); 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 – Art. 21 GDPR).
  • Where we have asked for your consent, you may withdraw consent at any time (Art. 7 par. 3 GDPR). If you ask to withdraw your consent to processing the data, this will not affect any processing which has already taken place at that time.

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. When addressing us, please provide us with specific information regarding your request. 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 in any case 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 this right at any time by contacting us at [email protected].

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 entities might my data be shared with?

The data controllers for your personal information are Parity Technologies Limited of c/o Ignition Law, 1 Sans Walk, London, England, EC1R 0LT and in some instances its Affiliates who may also act as joint controllers (Article 26 EU GDPR) regarding specific data processing operations. The legal basis for the joint processing and transmission of personal data between the companies lies, unless a different determination is made in individual cases, in the legitimate interests of the companies under Art. 6 para. 1 s. 1 lit. f GDPR, to transmit personal data for internal administrative purposes, including the processing of personal data of business partners, customers and employees.

Your data might be shared as part of our business operations with our Affiliates for the management and execution of group functions.

Your personal data might also be shared with the Web 3.0 Technologies Foundation, Baarerstrasse 14, 6300 Zug, Switzerland a third party with whom we are not affiliated but with whom we cooperate on a range of activities. In some cases your data will be jointly controlled (in accordance with Art. 26 GDPR) by the Web 3.0 Technologies Foundation and Parity in the framework of our cooperation. The essence of the corresponding data protection framework agreement will be made available on request.

How long will you retain my data?

Where you are a business partner, 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 in accordance with applicable law.

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.

Laws may require us to hold certain information of yours for specific retention 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 will you protect my data?

We strive to maintain the highest standards of security and Parity has put in place robust technical and organisational 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 unauthorised 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 unauthorised 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.

Cookie Policy

Our Sites use cookies. This helps us to provide you with a good experience when you browse our Sites and allows us to improve our Sites.

Cookies are small text files that are placed on your computer by the websites that you visit. They are widely used in order to make websites work, or work more efficiently, as well as to provide information to the owners of the site. The use of cookies is now standard for most websites. If you are uncomfortable with the use of cookies, you can manage and control them through your browser, including removing cookies by deleting them from your ‘browser history’ (cache) when you leave the site. See the subsection “How to manage cookies” for further information.

We use the following categories of cookies:

Necessary cookies

The law states that we can store cookies on your device if they are strictly necessary for the operation of this site or provision of our services. Necessary cookies in particular help make a website usable by enabling basic functions like page navigation and access to secure areas of the website. The website cannot function properly without these cookies.

Analytical or performance cookies

These are cookies that are not strictly necessary for the operation of this site or provision of our services, but they enhance the use of the Online Services by remembering certain choices you may make and providing enhanced features. For example, they are used to remember site preferences or choices, such as remembering preferences for language, country, region or other online settings made (e.g. text size, fonts).

These cookies allow us to recognise and count the number of visitors to our Sites and how visitors move around our Sites when they are using them. This helps us to improve the way our website works, for example, by ensuring that users are finding what they are looking for easily.

Functional and marketing cookies placed by third-party providers

Our Sites contain third-party embedded content or allow certain features from external providers, as described below. Please be aware that if you click, view or interact with this third-party content in any way additional third-party cookies may be placed on your browser by them. These external providers have their own terms and conditions and cookie policies, which we have no control over. Party does not directly place these cookies or receive any information about you from them.

Our Sites use the following external providers

  • YouTube. This Site uses the YouTube embedding feature to display and play videos from YouTube, operated by Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland; "Google"). We use the YouTube service to provide videos in a user-friendly manner. We use YouTube in the privacy-enhanced mode. According to Google, the privacy-enhanced mode of the YouTube embedded player prevents the use of views of embedded YouTube content from influencing the viewer's browsing experience on YouTube. This means that the view of a video shown in the privacy-enhanced mode of the embedded player will not be used to personalise the YouTube browsing experience, either within the privacy-enhanced mode embedded player on the Website or in the viewer's subsequent YouTube viewing experience. In addition, the view of a video shown in the privacy-enhanced mode of the embedded player will not be used to personalise advertising shown to the viewer outside of the Website.
