Privacy Policy
Last updated: September 29, 2026
This privacy policy (“Privacy Policy”) governs the data collection practices of Greenmark (“we”, “us”, “our”) in connection with your use of the Greenmark Adblocker browser extension offered on our website, https://greenmarkab.com, and through various browser extension stores (the “Extension”) and our related services (the “Services”).
We respect our users’ privacy and are committed to keeping data collection to an absolute minimum. This Privacy Policy provides transparent disclosures on how and why we collect, share, and use our users’ data. We encourage you to read it carefully before using the Extension or Services.
We may amend or revise this Privacy Policy from time to time. Changes take effect when the revised policy is displayed on this page, with the revision date reflected under “Last updated”. We encourage you to check this page regularly so you are fully informed of how your data is collected and used. Where changes materially affect you, we will use our best efforts to notify you through our website or the relevant browser extension stores.
What Information Do We Collect?
Non-Personal Information. When you use the Extension, we may collect non-identifiable, aggregated technical information (“Non-Personal Information”) that cannot be used to determine your identity. This may include standard web server log information, such as the uniform resource locator requested, HTTP referrer, and user agent string.
Personal Information. When you install or use the Extension, we may also generate a unique identification number – a random number used solely to keep track of collected data sets and, if required, to execute your data rights requests. This ID does not reveal your identity and is not generated from your personal information, but it may be considered Personal Information in some jurisdictions.
We make sure that usage data is cleaned and scrubbed on your device before being sent to our servers, so that only Non-Personal Information is transferred. You can opt out of usage data collection at any time (see “Opt-Out Right” below).
How Is the Data Used?
We use the information we collect solely to provide, maintain, and improve the Services – for example, to keep the Extension working correctly, to measure aggregate usage, and to develop, customize, and enhance the Extension’s performance. If you contact us for support, we use the details you provide to respond to your request.
How Is the Data Shared?
We do not sell, rent, or share Personal Information collected from you with third parties for their own marketing purposes. We may disclose information we have collected if we have a good-faith belief that disclosure is reasonably necessary to: (i) comply with applicable law, regulation, legal process, or governmental request; (ii) enforce our policies and agreements, including investigating potential violations; (iii) detect, prevent, or address illegal activity, fraud, or security issues; (iv) establish, exercise, or defend legal claims; or (v) prevent harm to the rights, property, or safety of us, our users, or the public.
If we combine Personal Information with Non-Personal Information, the combined information will be treated as Personal Information for as long as it remains combined. We may also share information with our affiliates in the event of a corporate transaction (such as a merger or asset sale), in which case the acquiring entity will assume the rights and obligations described in this Privacy Policy. We may appoint third-party service providers, operating under our instructions, who may need access to information in connection with providing and improving the Services on our behalf.
User Rights
Where provided under applicable law (such as within the European Union), you may have the right to: obtain information about our use of your Personal Information, obtain a copy of it, request rectification, request data portability, object to processing based on our legitimate interests, request restriction of processing, request deletion (subject to applicable exceptions), and withdraw your consent.
To assert any of these rights, please contact our Data Protection Officer at [email protected]. We may request proof of identity, and we reserve the right to charge a fee where permitted by law, for example where a request is excessive.
You may also have the right to lodge a complaint with a supervisory authority, subject to applicable law.
Opt-Out Right
You may opt out of usage data collection as follows:
- By right-clicking the extension icon and selecting “Opt out from sharing data”.
After you opt out, we will no longer collect and share your data as described in this Privacy Policy. Note that once you opt out, some or all features of the Extension may no longer be available.
Data Retention
Unless you instruct us otherwise, we retain the information we collect only for as long as needed to provide the Services and to comply with our legal obligations. We believe in data minimization: we only keep the information we truly need, and only for the period of time required.
How Do We Safeguard Your Information?
We use security methods and encryption when handling data, including transmitting it via modern cryptography. Unfortunately, no data transmission over the Internet can be guaranteed to be 100% secure. While we strive to protect your information, we cannot guarantee the absolute security, integrity, and privacy of any information exchanged between you and us through the Services.
Transfers of Personal Information are made in accordance with applicable data protection laws. Where personal data collected within the European Economic Area (“EEA”) is transferred outside the EEA, we take the steps required to ensure adequate safeguards, including the use of standard contractual clauses approved by the European Commission. For more information on our transfer mechanisms and security measures, please contact our Data Protection Officer at [email protected].
Minors
Children under 18 (or any younger age required under applicable laws) are prohibited from using the Services. If we become aware that a user under the age of 18 has shared any information with us, we will discard it. If you have reason to believe that a child under the age of 18 has shared any information with us, please contact our Data Protection Officer at [email protected].
Additional Privacy Information for California Residents
This section applies to California residents, as required under California privacy laws, including the California Consumer Privacy Act (“CCPA”). Under the CCPA, “personal information” is any information that identifies, relates to, describes, is reasonably capable of being associated with, or could reasonably be linked, directly or indirectly, with a particular California resident or household.
We do not sell your personal information, and we do not disclose it to third parties for a business purpose other than to our service providers, who are not permitted to use it except as necessary to perform services on our behalf. We collect the categories of personal information described in “What Information Do We Collect?” above, for the purposes described in “How Is the Data Used?” above.
California consumers have the following rights:
- Right to Opt Out of Sale: California residents have the right to opt out of the sale of their personal information. We do not sell personal information.
- Right to Delete: subject to certain exemptions, the right to request deletion of personal information we have collected about you.
- Right to Copy: the right to request a copy of the specific pieces of personal information we have collected about you in the prior 12 months.
- Right to Know: the right to request disclosure of certain information about how we have handled your personal information in the prior 12 months, including the categories collected, the sources, the business purposes, and the categories of third parties with whom it was shared.
You can exercise these rights, free of charge, up to twice every 12 months, by emailing [email protected]. When you submit a request, we will take steps to verify your identity by matching the information in your request to the information we maintain. We will make every reasonable effort to respond within 45 days of receiving a verified request, and if we are unable to meet that timescale, we will respond as soon as possible within the following 45-day period.
The CCPA prohibits discrimination against California consumers for exercising their rights. We will not deny you services, provide a different level or quality of services, or charge different prices because you exercised your rights under the CCPA.
Under California’s “Shine the Light” law (Cal. Civ. Code § 1798.83), California residents may request information about personal information shared with third parties for their own direct marketing use, once per calendar year, by submitting a written request to [email protected]. Please note that we do not share your personal information with third parties for their own marketing use.
