Ashlar Inc. ("Ashlar" "we" "our" or "us") respects your privacy and is committed to protecting it through our compliance with this privacy policy. Ashlar provides a block explorer known as ViewBlock that enables our customers to more easily view blockchain data, and a search engine known as Bitsearch that scrapes and processes data stored on public blockchains and provides our customers a way to search for such data.

This privacy policy explains our policies and practices regarding the information we collect from and about you. It is through this privacy policy that we intend to provide you with a level of comfort and confidence in how we collect, use, and safeguard personal and other information we collect and obtain, and how you can contact us if you have any questions or concerns. It is our sincere hope that by explaining our data handling practices we will develop a trusting and long-lasting relationship with you.

Data Minimization

We take every reasonable step to limit the volume of your personal data that we process to what is reasonably necessary. We do Not Engage in Automated Decision-Making without Human Intervention

We do not use automated decision-making without human intervention, including profiling, in a way that produces legal effects concerning you or otherwise significantly affects you.

Consequences of Not Providing Personal Data

You are not required to provide all personal data identified in this policy to use our Site or to interact with us offline, but certain functionality will not be available if you do not provide personal data. In addition, if you do not provide the personal data, we may not be able to respond to your requests, provide the Ashlar Services, or provide you with marketing that we believe you would find valuable.

Use of Cookies and Other Tracking Technologies.

The technologies we use or might use for automatic data collection may include:

  • Cookies (or browser cookies). A cookie is a small file placed on the hard drive of your computer. You may refuse to accept browser cookies by activating the appropriate setting on your browser. However, if you select this setting you may be unable to access certain parts of the Site. Unless you have adjusted your browser setting so that it will refuse cookies, our system will issue cookies when you direct your browser to the Site.
  • Pixels and Tags. Pixels and tags are site instrumentation tools that help us to determine, for instance, whether a page has been viewed or not and, if so, how many times. Emails or electronic newsletters we send may use tools (e.g., pixel tags or web beacons) to gather email metrics and information to improve the reader's experience such as how many of the emails are opened, if they were printed or forwarded, the type of device (e.g., mobile or PC) from which they were opened, and the associated member account details, which include name, city, state, and county associated with the applicable IP address. In general, any electronic image viewed as part of a webpage, including an ad banner, can act as a web beacon.
  • Session Logs. Session logs help us determine how people travel through the Site. In this way, we can structure our pages so that the information most frequently visited is easier to find. By tracking page visits, we can also determine if the information we are providing is being used. The only data gathered is the Internet Protocol (IP) address from which you came (which contains no personal data), the website that referred you, the pages you visited and the date and time of those visits.

Do Not Track Policy

Your web browser may offer you a "Do Not Track" option, which allows you to signal to operators of websites and web applications and services (including behavioral advertising services) that you do not wish such operators to track certain of your online activities over time and across different websites. We do not honor any web browser "Do Not Track"signals or other mechanisms that provide you with the ability to exercise choice regarding the collection of personally identifiable information about your online activities over time and across third-party websites or online services. At present, no universally accepted standards exist on how companies should respond to do-not-track signals. In the event a final universally accepted standard is established, we will assess and provide an appropriate response to these signals.

Third-party Responsibilities and Services.

We may use or partner with third-parties, agents or contractors for various purposes in connection with our business and operations (collectively, Service Providers), including blockchain projects that support Ashlar and billing, payment services and the performance of services on our behalf, such as gathering and analyzing information and the provision of services to you. may also link to in its search results. In the course of performing these responsibilities and providing such services, these other companies may have access to your personal data. We may also share information, including your personal data, with these Services Providers in order to enable them to perform these responsibilities and to provide these services. Many Services Providers have adopted their own privacy policies, which are not subject to control by Ashlar. You should always review the policies of these Service Providers to make sure that you are comfortable with the ways in which they collect, use, maintain, protect and disclose your information. We do not list our current Service Providers because they change from time to time. If you would like the names of any of Service Providers, please email us.

Service Providers that have access to your personally identifiable information in connection with providing services are required to keep your personal data confidential and are not permitted to use this personal data for any purpose other than to fulfill the services they are performing for Ashlar or the Site.

The Service Providers may also transmit cookies to your computer or device, when you click on ads that appear on or through the Service. Also, if you click on a link to a third-party website, such third party may also transmit cookies to you and we do not have any control over that. Please be aware that cookies placed by third parties may continue to track your activities online even after you are no longer using any our Services, and those third parties may not honor "Do Not Track" requests you have set using your web browser.

Ashlar may receive compensation from these Service Providers and other third parties.

Analytic Services

We use or may in the future use a variety of remarketing and analytic services including:

Google Analytics

We use a tool called "Google Analytics" in some of our products to collect information about use of the Site. Google Analytics collects information such as how often users visit the Site, what pages they visit when they do so, and what other sites they used prior to coming to this site. We use the information we get from Google Analytics only to improve the Site. Google Analytics collects only the IP address assigned to you on the date you visit the Site, rather than your name or other identifying information. We do not combine the information collected through the use of Google Analytics with personally identifiable information. Although Google Analytics plants a permanent cookie on your web browser to identify you as a unique user the next time you visit the Site, the cookie cannot be used by anyone but Google. Google's ability to use and share information collected by Google Analytics about your visits to this site is restricted by the Google Analytics Terms of Use and the Google Privacy Policy. You can prevent Google Analytics from recognizing you on return visits to this site by disabling cookies on your browser.

You can set preferences for how Google advertises to you using the Google Ad Preferences page, and if you want to you can opt out of interest-based advertising entirely by cookie settings or permanently using a browser plugin.

  • Performance of a contract: In most cases, we collect and use your personal data and other information to meet our obligations under a contract to which you are a party or pursuant to which we are providing services to you. For example, when you use our Ashlar Services, we will use your personal data to respond to your requests and to provide you with these services.

Ashlar has certified that it adheres to the Privacy Shield Principles with respect to such data. If there is any conflict between the policies in this privacy policy and the Privacy Shield Principles, the Privacy Shield Principles shall govern. To learn more about the Privacy Shield program, and to view our certification, please visit this site.

Ashlar is subject to the investigatory and enforcement powers of the U.S. Federal Trade Commission.

In compliance with the Privacy Shield Principles, Ashlar commits to resolve complaints about your privacy and our collection or use of your personal information transferred to the United States pursuant to Privacy Shield. European Union, UK, and Swiss individuals with Privacy Shield inquiries or complaints should first contact Ashlar by email.

Ashlar has further committed to refer unresolved privacy complaints under the Privacy Shield Principles to an independent dispute resolution mechanism, the BBB EU PRIVACY SHIELD. If you do not receive timely acknowledgment of your complaint, or if your complaint is not satisfactorily addressed, please visit this linkfor more information and to file a complaint. This service is provided free of charge to you.

If your Privacy Shield complaint cannot be resolved through the above channels, under certain conditions, you may invoke binding arbitration for some residual claims not resolved by other redress mechanisms. See Privacy Shield Annex 1.

EEA Individuals whose personal data is covered by this privacy policy have the right to access the personal data that Ashlar maintains about them and to correct, amend or delete such personal data if it is inaccurate or has been processed in violation of the Principles (except when the burden or expense of providing access, correction, amendment, or deletion would be disproportionate to the risks to the Data Subject's privacy, or where the rights of persons other than the Data Subject would be violated). Requests for access, correction, amendment or deletion should be sent to

If personal data covered by this privacy policy is to be used for a new purpose that is materially different from that for which the personal data was originally collected or subsequently authorized, or is to be disclosed to a non-agent third party, Ashlar will provide Data Subjects with an opportunity to choose whether to have their personal data so used or disclosed. To the extent required by the Privacy Shield Principles, Ashlar obtains opt-in consent for certain uses and disclosures of Sensitive Data (as defined in the GDPR).

Consistent with the Privacy Shield Principles, Ashlar may transfer personal data to third parties, including transfers from one country to another. We will only disclose an individual's non-public personal data to third parties under one or more of the following conditions:

  • With the individual's permission to make the disclosure.
  • Where required to the extent necessary to meet a legal obligation to which Ashlar is subject, including a lawful request by public authorities and national security or law enforcement obligations and applicable law, rule, order, or regulation.
  • Where reasonably necessary for compliance or regulatory purposes, or for the establishment of legal claims.
  • The disclosure is to Service Providers (as described above), to our customers and/or to certain employees in connection with the operation of our business, and as consistent with the purpose for which the personal data was collected. We maintain written contracts with these third parties and require that these third parties provide at least the same level of privacy protection and security as required by the Privacy Shield Principles.

To the extent provided by the Privacy Shield Principles, Ashlar remains responsible and liable under the Privacy Shield Principles if a third-party that it engages to process personal data on its behalf does so in a manner inconsistent with the Privacy Shield Principles, unless Ashlar proves that it is not responsible for the matter giving rise to the damage.
