- Blockchain Access UK Ltd.; and
- Blockchain.com Group Holdings, Inc.
You may contact our Data Protection Officer (“DPO”) by email at [email protected].
2. Collection of Personal Data
When you access or use the Services, we collect the following information:
Information you may provide to us: You may give us information about you by filling in forms on our website or through our app or by corresponding with us by phone, email or otherwise. This includes information you provide when you register to use the Services and when you report a problem with the website or with our app.
Information we collect about you: With regard to each of your visits to our website or our app we automatically collect the following information:
- Login Information: We log technical information about your use of the Services, including the type of browser and version you use, the wallet identifier, the last access time of your wallet, the Internet Protocol (IP) address used to create the wallet and the most recent IP address used to access the wallet.
- Device Information: We collect information about the device you use to access your account, including the hardware model, operating system and version, and unique deviWe ce identifiers, but this information is anonymised and not tied to any particular person.
- Wallet Information If you create a Blockchain Wallet through our Services, you will generate a public and private key pair. When you log-out of the Wallet, we collect an encrypted file that, if unencrypted, would contain these keys, along with your transaction history. When you enable notifications through your Account Settings, we will collect the unencrypted public key in order to provide such notifications. Under no circumstances do we collect an unencrypted private key from you, nor can we decrypt any Wallet file data.
- Transaction Information: In connection with our Conversion Service, as such term is defined in our User Agreement, we may collect and maintain information relating to transactions you effect in your Wallet that convert one virtual currency to another (e.g. Bitcoin for Ether).
Information We Collect Required By Law, Rule, or Regulation: Depending on the Service, we may collect information from you in order to meet regulatory obligations around know-your-customer (“KYC”) and anti-money laundering (“AML”) requirements. Information that we collect from you includes the following:
- Full name
- Residential address
- Contact details (telephone number, email address)
- Date and place of birth, gender, place of citizenship
- Bank account information and/or credit card details
- Your status as a politically exposed person
- Source of funds & proof of address
- Passport and/or national driver’s license or government-issued identification card to verify your identity
- Transaction history and account balances in connection with your use of certain Services.
Information We Collect from Other Sources: We also receive information from other sources and combine that with the information we collect through our Services. For instance:
- We use third-party services that may be co-branded as Blockchain but will do so with clear notice. Any third-party services may collect information as determined by their own privacy policies.
- Banks or payment processors that you use to transfer fiat currency may provide us with basic Personal Data, such as your name and address, as well as, your bank account information.
- Advertising or analytics providers may provide us with anonymised information about you, including but not limited to, how you found our website.
3. Use of Personal Data
We will use your Personal Data, to:
- Understand and strive to meet your needs and preferences in using our Services;
- Develop new and enhance existing service and product offerings;
- Manage and develop our business and operations;
- Carry out any actions for which we have received your consent;
- Prevent and investigate fraudulent or other criminal activity;
- To address service requests and resolve user questions; and
- Meet legal and regulatory requirements.
We also reserve the right to use aggregated Personal Data to understand how our users use our Services, provided that those data cannot identify any individual.
We also use third-party web analytics tools that help us understand how users engage with our website. These third-parties may use first-party cookies to track user interactions to collect information about how users use our website. This information is used to compile reports and to help us improve our website. The reports disclose website trends without identifying individual visitors. You can opt-out of such third-party analytic tools without affecting how you visit our site. For more information on opting-out, please contact [email protected].
We will process your Personal Data legally and fairly and not use it outside the purposes of which we have informed you, including selling it individually or in the aggregate for commercial use.
4. Disclosure of Personal Data
- Companies within the Blockchain corporate family located in the United States, the United Kingdom, and the EEA in order to provide the Services to you.
- Cloud service providers to store certain personal data and for disaster recovery services, as well as, for the performance of any contract we enter into with you.
- Fraud detection service providers who will run certain fraud detection checks against Personal Data provided.
- Spam and abuse detection providers making software available designed to prevent users from programatically using the Services in unsupported ways.
We also may share Personal Data with a buyer or other successor in the event of a merger, divestiture, restructuring, reorganisation, dissolution or other sale or transfer of some or all of Blockchain’s assets, whether as a going concern or as part of bankruptcy, liquidation or similar proceeding, in which Personal Data held by Blockchain is among the assets transferred.
We shall require any third-party, including without limitation, any government or enforcement entity, seeking access to the data we hold to a court order, or equivalent proof that they are statutorily authorised to access your data and that their request is valid and within their statutory or regulatory power.
Funding and transaction information related to your use of certain Services may be recorded on a public block chain. Public block chains are distributed ledgers, intended to immutably record transactions across wide networks of computer systems. Many block chains are open to forensic analysis which can lead to deanonymisation and the unintentional revelation of private financial information, especially when block chain data is combined with other data.
Because block chains are decentralised or third-party networks that are not controlled or operated by Blockchain or its affiliates, we are not able to erase, modify, or alter Personal Data from such networks
5. Security of Your Personal Data
We protect Personal Data with appropriate physical, technological and organisational safeguards and security measures. Your Personal Data comes to us via the internet which chooses its own routes and means, whereby information is conveyed from location to location. We audit our procedures and security measures regularly to ensure they are being properly administered and remain effective and appropriate. Every member of Blockchain is committed to our privacy policies and procedures to safeguard Personal Data. Our site has security measures in place to protect against the loss, misuse and unauthorised alteration of the information under our control. More specifically, our server uses TLS (Transport Layer Security) security protection by encrypting your Personal Data to prevent individuals from accessing such Personal Data as it travels over the internet.
6. Retention of Your Personal Data
The length of time we retain Personal Data outside our back-up system varies depending on the purpose for which it was collected and used, as follows:
- Data you provide to us when subscribing for our Services: while user remains active, stored in the UK.
- Country location data: while user remains active, stored in the UK.
- Data on your preferences: while user remains active, stored in the UK.
- IP address login: until subsequent login from a new IP, stored in the UK.
When Personal Data is no longer necessary for the purpose for which it was collected, we will remove any details that identifies you or we will securely destroy the records, where permissible. However, we may need to maintain records for a significant period of time (after you cease using a particular Service) as mandated by regulation. For example, we are subject to certain anti-money laundering laws that require us to retain the following, for a period of five (5) years after our business relationship with you has ended.
- A copy of the records we used in order to comply with our client due diligence obligations;
- Supporting evidence and records of transactions with you and your relationship with us.
Except where prohibited by law, this period may extend beyond the end of the particular relationship with us, but only for as long as we are bound to do so for the audit, regulatory or other accounting purposes. When Personal Data is no longer needed, we have procedures either to destroy, delete, erase or convert it to an anonymous form. If you have opted-out of receiving marketing communications, we will hold your details on our suppression list so that we know you do not want to receive these communications.
After you have terminated the use of our Services, we reserve the right to maintain your Personal Data as part of our standard back-up procedures in an aggregated format.
7. Storage of Personal Data
Blockchain stores your Personal Data at secure locations in the EU. Blockchain ensures that appropriate security standards are in place regarding the safeguarding, confidentiality, and security of Data.
The information that we collect from you will be transferred to, and stored in, destinations outside of your country and the European Economic Area ("EEA") as described below:
We may transfer your Personal Data outside the EEA and the UK to other company subsidiaries, service providers and business partners (i.e., Data Processors) who are engaged on our behalf. To the extent that we transfer your Personal Data outside of the EEA and UK, we will ensure that the transfer is lawful and that Data Processors in third countries are obliged to comply with the GDPR and the UK Data Protection Act 2018. If transfers of Personal Data are processed in the US, we may in some cases rely on applicable standard contractual clauses.

If we have disclosed your Personal Data to others, we will let them know about the restriction of processing where possible. If you ask us, if possible and lawful to do so, we will also inform you with whom we have shared your Personal Data so that you can contact them directly.

You can ask us to stop processing your Personal Data, and we will do so if we are:
- Relying on our own or someone else’s legitimate interests to process your Personal Data, except if we can demonstrate compelling legal grounds for the processing;
- Processing your Personal Data for direct marketing; or
- Processing your Personal Data for research, unless we reasonably believe such processing is necessary or prudent for the performance of a task carried out in the public interest (such as by a regulatory or enforcement agency).
Automated decision-making and profiling
If we make a decision about you based solely on an automated process (e.g. through automatic profiling) that affects your ability to access our Services or has another significant effect on you, you can request not to be subject to such a decision unless we can demonstrate to you that such a decision is necessary for entering into, or the performance of, a contract between us. Even if a decision is necessary for entering into or performing a contract, you may contest the decision and require human intervention. We may not be able to offer our Services if we agree to such a request by terminating our relationship with you. You can exercise any of these rights by contacting us at [email protected].
