BlockSite – Privacy Policy for Website, Mobile App, and Desktop App

[Last modified: October 14, 2021]


This privacy policy (“Privacy Policy“) governs the data collection practices BlockSite LP (“Company”, “us”, “we” and “our”) uses when you use our BlockSite mobile app or desktop app (“BlockSite Product”) or our website, (the “Website”). This Privacy Policy is provided to make important disclosures on how or why we collect, share and use our users’ information. Our users’ privacy is important to us. We encourage you to read the Privacy Policy carefully prior to using our BlockSite Product and use it to make informed decisions. If you would like to use our BlockSite add-on extension, please be sure to review and agree to the terms of the separate privacy policy available on our Website.

By using the BlockSite Product or Website, you agree to the terms of this Privacy Policy. Your continued use of the BlockSite Product or Website constitutes your agreement to this Privacy Policy. This Privacy Policy is part of our End User License Agreement (Link: https:// and, to the extent that the processing of personal data is based on consent (see below), is a legally binding agreement between you and the Company. Definitions herein shall have the same meaning as defined therein. If you do not agree to these terms, please do not access or use the BlockSite Product or Website.


What Information Do We Collect?

The information we collect includes non-identifiable information which may be made available or gathered via the user’s use of the BlockSite Product and, where applicable and enabled by users of the mobile app, via the Android accessibility service (“Non-Personal Information“). This Non-Personal Information is cleaned and scrubbed on your device – prior to being sent to our servers and prior to any other use – for the purpose of removing information that could be used to identify you. As such, we are not aware of and cannot determine the identity of the user from which the Non-Personal Information is collected.

Non-Personal Information collected through your use of the desktop app includes:

  • Browsing history information (URLs/domains visited)
  • Internet Protocol (IP) address – but note that we permanently delete the last portion of the IP address and hash the full IP address before storing it, thus preventing us from having the ability to use it to transmit any information to your device or to otherwise identify you
  • GUID – a random number generated on your device upon app installation and stored in order to distinguish one user from another, which cannot be used to transmit any information to your device or to otherwise identify you
  • User agent – which helps identify which browser is being used, what version, and on which operating system
  • Tracker details – our tracker type and version
  • Transition Type – how the current URL was reached (i.e., via manual typing, tab switching, or link clicking)
  • Browser profile counter – a random number generated to distinguish between different users using the same browser

Non-Personal Information collected through your use of the mobile app includes:


  • Technical information (operating system version, device model name, screen size, and mobile network code, browser type);
  • Browsing history information (URLs/domains visited, and the dates, times and durations of visits)
  • List of installed apps (app name, app ID, installation and update date, version, whether app is a system app, whether app is on home page)
  • App usage (including duration of use) – but note that we do not collect data from within the installed apps, but rather solely aggregated data concerning use itself
  • GUID – a random number generated on your device upon app installation and stored in order to distinguish one user from another, which cannot be used to transmit any information to your device or to otherwise identify you
  • Internet Protocol (IP) address – but note that we permanently delete the last portion of the IP address and hash the full IP address before storing it, thus preventing us from having the ability to transmit any information to your device or to otherwise identify you.

Android app permissions requested (“Permission”):

  • App Usage: this Permission enables us to understand the user’s browsing habits, in order to enable the user to improve their productivity.
  • Accessibility: this Permission enables us to block unwanted websites or apps and enable the safe use of your device and browser, which is the app’s core functionality. For more information, please see “How is the Data Used” Section below.

To access these Permissions, you will need to explicitly enable them through an in-app permission or the mobile settings. You may disable these Permissions at any time. However, depending on the Permission you choose to disable, a feature or all features may not operate properly. We share the information obtained through the Permissions to provide the Services.


  • Device information (operating system version and device model name)
  • Browsing history information (URLs/domains visited, and the dates and times of visits)
  • Internet Protocol (IP) address – but note that we permanently delete the last portion of the IP address and hash the full IP address before storing it, thus preventing us from having the ability to transmit any information to your device or to otherwise identify you
  • Country
  • GUID – a random number generated on your device upon app installation and stored in order to distinguish one user from another, which cannot be used to transmit any information to your device or to otherwise identify you
  • IDFA (Apple identifier for advertisers)
  • User agent – which helps identify which browser is being used, what version, and on which operating system

Such Non-Personal Information is processed for the purposes described in the “How Is the Data Used?” section hereunder.

We do not collect from you any individually identifiable information, namely information that identifies an individual or may with reasonable effort be used to identify an individual (“Personal Information“) except as may be voluntarily provided by you if and when you register and create an account or otherwise contact us, such as your name and email address, provided that such information will be used solely to communicate with and support you, and will not be shared with any third parties except as set forth in the “How is the Data Shared” section below.

How is the Data Used?

We collect your information during your access or use of the BlockSite Website or the BlockSite Product as detailed above, and use that information to block your access to certain sites based on parameters you define and control (the “Services”). We use that information based on our legitimate interests in promoting and improving the BlockSite Product and our services, on the necessity of such information for the provision of the BlockSite Product and our services where applicable (as described in this Privacy Policy) or, where permitted under applicable law, on the implied consent that you provide by using the BlockSite Product, or by requesting support, registering for the BlockSite Product, or through your use of the various forums and blogs available within the website.

In practice, in order to provide the BlockSite Product and the Services, we need to scan the webpages you browse, and we need to retrieve the apps you are trying to open. Meaning, we use the data collected from you, as detailed and specified above, and transmit it to our servers for the purpose of enabling the BlockSite Product and in order to know when and where there is content, a website or an app to block. Thus, the processing of Non-Personal Information in this context is necessary for a user-facing feature, namely the provision of the Services as described above. Accordingly, without access to such information, some or all of the site-blocking would not work. You acknowledge and agree that by using the BlockSite website and by downloading and using the BlockSite Product, you request that we provide you with the Services.

We also use Non-Personal Information, aggregated information or statistics regarding your use of the Services, which do not describe or identify any individual user, in order to monitor and understand user interest and improve the Services. 

How is the Data Shared?

We do not share any Personal Information collected from you with third parties or any of our partners. We may disclose information you submitted if we have a good faith belief that disclosure of such information is reasonably necessary:

(i) to comply with any applicable law, regulation, legal process or governmental request;

(ii) to enforce our policies (including our policies and agreements), including investigations of potential violations thereof;

(iii) investigate, detect, prevent, or take action regarding illegal activities or other wrongdoing, suspected fraud or security issues;

(iv) to establish or exercise our rights to defend against legal claims;

(v) to prevent harm to the rights, property or safety of us, our users, yourself or any third party; or

(vi) for the purpose of collaborating with law enforcement agencies or in case we find it necessary in order to enforce intellectual property or other legal rights.

Note that we may also appoint third-party service providers, or have certain services provided by one of our affiliated companies, operating under our instructions, who may need access to your information in connection with their services on our behalf. Transfers of your Personal Information will be made in accordance with applicable data protection laws.

We will take the necessary steps to ensure that international transfers of personal data (including Personal Information) meet all requirements under applicable data protection laws. When personal data collected within the European Economic Area (“EEA“) is transferred outside the EEA, we will take the steps necessary to ensure that the transfer of such data provides sufficient safeguards, and you may exercise your rights, where applicable, to receive information on such transfer mechanism.

Additional Rights of California Users

California residents have certain additional rights, pursuant to California privacy laws, including the California Consumer Privacy Act (“CCPA”). The CCPA defines “personal information” as any information that identifies, relates to, describes, is reasonably capable of being associated with, or could reasonably be linked, directly or indirectly, to a particular California resident or household, but excluding publicly available data. This section does not apply to our handling of publicly available information or other personal information subject to an exemption pursuant to Section 1798.145(c)-(f) of the CCPA.

Personal Information that We Collect, Disclose, and Sell

The following list (our “Notice of Collection”) describes the categories of personal information about California residents that we collect, from the sources listed in the “What Information Do We Collect” section above. We do not sell your personal information or disclose it to third parties for a business purpose. We may disclose these categories of personal information to our service providers, solely for their use as necessary to perform services on our behalf. The personal information collected is used according to the “How is the Data Used” section above. 

Note that the term “sale” is defined broadly in the CCPA to include any exchange of data for consideration of any kind.

If you submit one of these requests, we will first try to verify your identity. Then, we will attempt to match the information provided in your request with personal information we have about you, if any. If you have created an account on our Product or Website, we may ask you, as part of our identity verification process, to sign in to your account. We will take further action on your request only where we are reasonably satisfied that we have verified your identity. We will use reasonable efforts to respond to your request within forty-five days after we receive and verify it, or, if we cannot do so, then we will respond over the following forty-five day period.  

The CCPA does not allow any discrimination against California consumers for exercising their rights under the CCPA. In addition, financial incentives offered to California consumers related to their personal information are subject to certain requirements imposed by the CCPA. In particular: (a) A company may not discriminate against a consumer who exercised his/her rights under the CCPA, such as by denying or providing a different level or quality of services to the consumer, or by charging different prices or rates to, or imposing penalties on the consumer, unless reasonably related to the value provided by the consumer’s data.

Your Rights under Califormia’s Shine-the-Light Law.  California’s “Shine-the-Light” law (Cal. Civ. Code § 1798.83), provides that California residents who provide certain personal information to us have the right to request and obtain from us, free of charge, information about the personal information we have shared with third parties for their own direct marketing use (if any). These requests may be made once each calendar year regarding information shared with a third party in the previous calendar year. To make such a request, please submit the request in writing to, and include in the request a statement confirming that you are a California resident.


We reserve the right to periodically amend or revise the Privacy Policy; material changes will be effective immediately upon the display of the revised Privacy Policy. The last revision date will be reflected in the “Last modified” heading. Your continued use of the BlockSite Product, following the notification of such amendments on our website, constitutes your acknowledgement of such amendments to the Privacy Policy and, where the processing of personal data is based on consent (see above), your agreement to be bound by the terms of such amendments.
