2. Collection of Personal Data
When you access or use the Services, we collect the following information:

- Wallet Information If you create a Blockchain.com 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 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.com 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.com 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.com’s assets, whether as a going concern or as part of bankruptcy, liquidation or similar proceeding, in which Personal Data held by Blockchain.com 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.com 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.com 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.
Protection of Social Security Numbers
The processing of Social Security Numbers (“SSN’s”) in the United States of America is subject to certain protections under the law. Blockchain.com will only process your SSN in order to comply with federal and state laws and/or where it is necessary to provide you with a relevant service or product. Where we do so we will adhere to our internal policies and procedures on the handling of sensitive data such as SSNs with appropriate disciplinary sanctions for employees who do not adhere to these.
Our measures include:
Technical and organizational measures to protect the security of your SSN, including our industry standard security measures.
Restricting access to only those employees with a legitimate need for access based upon their role and duties.
Only processing your SSN for the stated purpose for which it is collected.
Only sharing your SSN externally when legally required to do so or when necessary to provide you with a requested service or product.
When sharing externally or internally, doing so in a safe and secure manner.
Secure destruction/disposal of your SSN in line with our retention practices in a manner which protects the underlying confidentiality of the data.
7. Storage of Personal Data
Blockchain.com stores your Personal Data at secure locations in the EU. Blockchain.com 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.
8. Your Rights

It is important to us that your Personal Data is up-to-date. We will take all reasonable steps to make sure that your Personal Data remains accurate, complete and up-to-date. If the Personal Data we hold about you is inaccurate or incomplete, you are entitled to have it rectified.

If we have disclosed your Personal Data to others, we will let them know about the erasure request 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 block or suppress the processing of your Personal Data in certain circumstances, such as, if you contest the accuracy of that Personal Data or object to us processing it. It will not stop us from storing your Personal Data. We will inform you before we decide not to agree with any requested restriction. 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.

- 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].

Pursuant to the CCPA, upon request and upon our verification of your identity, California residents may:

- Obtain a copy of your Personal Information in a format that would permit you to transfer that Information to another Repository;
- Submit a request for deletion of Personal Information, subject to certain exceptions, including (without limitation) in the event that we may need to retain Personal Information to complete the transaction for which the Personal Information was collected, detect security incidents, protect against illegal activity, exercise certain rights of free speech, comply with legal obligation or for internal uses permitted by law. If your request is subject to any exception, we may deny your request to delete your data. Please note that you must verify your identity and request before further action is taken by us. To do so, we will notify you of what we require via email.
- To be free from unlawful discrimination for exercising your rights under the CCPA.
Do Not Sell My Personal Information
Blockchain.com does not sell Personal Information in the normal course of our business, but the CCPA defines sale more broadly than the traditional sense of an exchange of data for money and may encompass transactions in which we may share your Personal Information. Accordingly you may, subject to exceptions in CCPA, request that Blockchain.com not “sell” your Personal Information to the extent that we may do so. Please be aware that certain sharing of your Personal Information, such as disclosures of that Information to “Service Providers” as that term is defined and in accordance with CCPA, or for certain business operations of Blockchain.com, are not considered “sale” of Personal Information.
CCPA comprises provisions that explicitly prohibit us from making any adverse decisions about you or your account based upon your exercise of this right (“non-discrimination”).
The CCPA permits you to request certain information regarding our disclosure of Personal Information to third parties for their direct marketing purposes.
To exercise any of the above rights, you may contact us at [email protected]. Consistent with California law, you may designate an authorised agent to make a request on your behalf. In order to designate an authorised agent, please contact us via email [email protected]. Please note that any proposed appointment is subject to verification checks and we may deny requests from agents who are unable to prove their identity or provide proof of authority to act on your behalf.
While many browsers permit you to send a signal about your Do Not Track (“DNT”) preferences, we do not respond to DNT signals sent from browsers.Children’s Online Privacy Protection Act
Blockchain.com complies with the Children’s Online Privacy Protection Act COPPA, which requires the consent of a parent or guardian for the collection of personally identifiable information from children under 13 years of age. Blockchain.com does not knowingly collect, use or disclose personal information from children under 13, or equivalent minimum age in the relevant jurisdiction, without verifiable parental consent. However, it is possible that we may inadvertently receive information pertaining to children under 13. If you believe that we have received information about your child that is under the age of 13, please do not hesitate to notify us at [email protected]. When we receive your notification, we will obtain your consent to retain the information or will delete it permanently.
