Last updated: 2026-05-24 – Effective: 2026-05-23 – Version: 2.2
This End User License Agreement (the "EULA") is a binding legal contract between you ("you," "your") and Adblock Labs, Inc., 2810 N Church St, Unit 28339, Wilmington, DE 19802, United States ("Adblock Labs," "we," "us," "our"). This EULA governs your use of:
This EULA does not govern your use of our adblocklabs.com websites or our marketing landing pages, which is instead covered by the Privacy Policy and any website-specific terms of service we publish.
By installing, copying, accessing, or otherwise using the Software, you agree to be bound by this EULA. If you do not agree, do not install or use the Software, and uninstall it if it is already installed. If you are accepting this EULA on behalf of a company or other legal entity, you represent that you have authority to bind that entity, and "you" refers to that entity.
The Software is licensed, not sold. Your rights to use the Software are limited to those expressly granted in this EULA, and we reserve all rights not expressly granted to you.
Subject to your continuous compliance with this EULA and (where applicable) your payment of all fees due, Adblock Labs grants you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable license to:
You may deactivate a previously activated device through the in-application Manage Subscription screen and then activate a new device, subject to any rate limits we impose to prevent abuse.
This license is granted for as long as your subscription remains active (or for as long as we make a free version of the Software available to you, if you are not a paid subscriber). It terminates automatically as described in Section 15.
By installing the Software, you authorize Adblock Labs to install the components necessary to perform ad- and tracker-filtering on your computer. These include:
The Software's local TLS inspection is performed for the Software's stated purpose of ad and tracker filtering, as disclosed prominently in this EULA and in our Privacy Policy. It happens entirely on your computer; the Software does not export decrypted traffic, decryption keys, browsing-content metadata, or any other property of inspected traffic to Adblock Labs or any third party. This on-device architecture is consistent with how browser-based and network-level ad-blockers have operated for many years and with industry guidance on disclosed-purpose TLS inspection.
If you do not agree to the installation of any of these components, do not install the Software, and uninstall it as described in Section 15 below if it is already installed.
To support the trust-and-safety commitments described above, Adblock Labs commits that the Software:
Adblock for Windows is available on a subscription basis. The pricing, currency, billing period, and the specific features included in each plan are presented to you on the checkout page before you confirm your purchase.
We may offer a time-limited free trial at our discretion. At the end of the trial period, the Software's premium features will deactivate unless you have started a paid subscription.
When you start a paid subscription, you authorize Adblock Labs and our payment processors (Chargebee Inc. and Stripe, Inc.) to charge your designated payment method on a recurring basis. The exact terms of your subscription — including the amount charged today, the renewal price (if different), and the renewal cadence — are disclosed clearly and conspicuously on the checkout page before you confirm your purchase.
Renewals will be charged at the renewal price disclosed at checkout, not at the discounted introductory price (if any). If we change the renewal price for your plan, we will notify you by email at least 30 days before the change takes effect, and you may cancel before the change applies.
You can cancel your subscription at any time through:
When you cancel, your subscription remains active for the rest of the billing period you have already paid for, and we will not charge you again. We will not delete your account data automatically on cancellation — see the Privacy Policy, Section 9 (Retention) for details on what we retain and for how long.
If you are a resident of California, New York, Colorado, Oregon, Tennessee, or another U.S. state with an automatic-renewal law, the following are clear and conspicuous disclosures:
You agree to pay all fees applicable to your subscription plan at the price disclosed to you at checkout. Prices are shown exclusive or inclusive of value-added tax depending on your country of residence; the checkout page displays the final total before you confirm.
Your payment is processed by Chargebee Inc. (subscription billing and hosted checkout) and Stripe, Inc.(card and payment-method processing). Card details and other payment credentials are collected directly by these processors and are subject to their own terms and privacy policies; we never see your full card number, CVV, or PIN.
You are responsible for all sales, use, value-added, withholding, and similar taxes assessed on your subscription, except for taxes assessed on our net income.
If your payment method is declined, we will retry the charge on a schedule defined by our payment processor (typically over several days). If we cannot collect payment, your subscription will be suspended and your premium features will deactivate until you provide a working payment method.
We offer a 30-day money-back guarantee on new subscriptions only. The 30-day window begins on the date of your initial purchase, measured by the invoice date issued by our billing provider.
To request a refund:
If you are eligible, we will refund the purchase to your original payment method within 5–10 business days.
We may decline a refund where we have reasonable evidence of abuse (for example, repeated refund-and-resubscribe cycles).
Nothing in this section limits any statutory right of withdrawal, cooling-off period, or refund you may have under applicable consumer-protection law (for example, the 14-day right of withdrawal under EU Directive 2011/83/EU and the UK Consumer Contracts Regulations 2013 for distance contracts). If you are a consumer in the EEA, the UK, or Switzerland, you may use the model withdrawal form provided in those jurisdictions.
By starting to use the Software immediately after purchase, you may be waiving your right of withdrawal for digital content where applicable law permits such waiver; please consult your local consumer-protection authority if you are unsure.
You agree that you will not, and will not allow any third party to:
The Software is offered as a tool to help you control how advertising and tracking content is delivered to your own device. You are responsible for ensuring that your use of the Software complies with the terms of service of the websites and online services you visit.
By installing and using the Software, you acknowledge that:
You can stop all telemetry and filter-list traffic by uninstalling the Software. Some traffic is strictly necessaryfor the Software's operation (for example, the initial filter-list download, license validation, and update delivery); you cannot disable that traffic while keeping the Software installed.
The Software includes an automatic-update component that periodically checks Adblock Labs servers for new signed releases.
You agree not to attempt to prevent the Software from checking for or applying updates by tampering with our certificates, our update endpoints, or our cryptographic verification logic.
The Software incorporates third-party software components, including open-source components, which are licensed under their own terms. A current list of these components, with attribution and a reference to each component's license, is available on request from legal@adblocklabs.com and at https://adblocklabs.com/legal/third-party-licenses. We update this list periodically as the Software's dependencies change.
Where any third-party open-source component is licensed under terms that conflict with this EULA, the open-source license terms govern your use of that component.
If you need the full source code of any open-source component listed, or a copy of any component's full license text, please contact us at legal@adblocklabs.com. We will provide the requested material at no charge for any component whose license obligates us to do so.
The Software and all worldwide intellectual property rights in and to the Software — including all copyrights, patents, trademarks, trade secrets, and other proprietary rights — are and shall remain the exclusive property of Adblock Labs and its licensors. Nothing in this EULA transfers ownership of the Software or any associated intellectual property rights to you.
"Adblock," "Adblock Labs," and the Adblock Labs logo are trademarks of Adblock Labs, Inc. You are not granted any right to use these marks except as expressly permitted by a separate written agreement with us.
You may, at your option, provide us with comments, suggestions, ideas, or feedback about the Software through the in-application support form, email, our community channels, or other means ("Feedback"). You grant us a perpetual, worldwide, royalty-free, irrevocable, non-exclusive license to use, modify, and incorporate the Feedback into our products and services without any obligation to you.
You agree that you will not include in any Feedback any information that you consider confidential, proprietary, or subject to a third-party non-disclosure obligation. We have no obligation to use any Feedback or to credit you for it.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SOFTWARE IS PROVIDED "AS IS"AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. ADBLOCK LABS AND ITS LICENSORS AND SUPPLIERS DISCLAIM ALL WARRANTIES, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, TITLE, QUIET ENJOYMENT, AND ACCURACY.
WE DO NOT WARRANT THAT:
You use the Software at your own risk and are responsible for any damage to your device or data that results from your use.
If you are a consumer in the European Economic Area, the United Kingdom, Switzerland, Australia, or another jurisdiction that grants non-excludable statutory warranties to consumers, nothing in this EULA limits or excludes those statutory rights. Where applicable law does not permit the exclusion of certain warranties, the disclaimers in this Section 12 apply to the maximum extent permitted by that law.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL ADBLOCK LABS, ITS AFFILIATES, OR ITS LICENSORS OR SUPPLIERS BE LIABLE TO YOU FOR ANY:
ARISING OUT OF OR IN CONNECTION WITH THIS EULA OR YOUR USE OF (OR INABILITY TO USE) THE SOFTWARE, WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Aggregate cap. Our total cumulative liability to you under this EULA — for any and all causes of action, whether in contract, tort, or otherwise — is limited to the greater of (a) the fees you have actually paid to us under this EULA in the 12 months preceding the event giving rise to the claim, and (b) US$100.
The limitations in this Section 13 do not apply to (a) liability that cannot be excluded or limited under applicable law (including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any statutory consumer right that cannot be waived), and (b) breach of Section 6 (Restrictions) and Section 16 (Export controls and sanctions) (which are not subject to the aggregate cap).
You agree to defend, indemnify, and hold harmless Adblock Labs, its affiliates, and its and their respective officers, directors, employees, contractors, and agents from and against any claim, demand, loss, liability, or expense (including reasonable attorneys' fees) arising out of or related to:
We will give you prompt written notice of any claim subject to indemnification, allow you to control the defense and settlement of the claim (provided that any settlement that requires us to admit fault or pay money is subject to our prior written approval), and provide reasonable cooperation at your expense.
This EULA is effective when you accept it and remains in effect until terminated.
You may terminate this EULA at any time by uninstalling the Software from all of your devices and (if you have a paid subscription) cancelling the subscription. Cancellation procedures are described in Section 3.3. When you uninstall, the uninstaller removes all Software components, reverts the system settings the Software changed, and removes the "Adblock CA" root certificate described in Section 2.1 from your computer's Trusted Root Certification Authorities store. If you originally installed an early version of the Software whose uninstaller did not perform the certificate removal, please contact support@adblocklabs.coma and we will provide the manual removal steps.
We may suspend or terminate your license — and, where applicable, your subscription — immediately and without notice if:
On termination, your right to use the Software ceases. Your activation tokens will be invalidated by our license-management vendor (Keygen) within a short period. You must uninstall the Software promptly.
Sections 6, 10, 11, 12, 13, 14, 16, 18, and 19 survive termination of this EULA.
You acknowledge that the Software is subject to the export control and economic sanctions laws of the United States and other jurisdictions, including the U.S. Export Administration Regulations (15 C.F.R. Parts 730–774), the regulations administered by the U.S. Department of the Treasury's Office of Foreign Assets Control ("OFAC"), and the analogous laws of the European Union and the United Kingdom.
You represent and warrant that:
If you are a U.S. government end user, the Software is "commercial computer software" and the associated documentation is "commercial computer software documentation" as those terms are used in the Federal Acquisition Regulation and the Defense Federal Acquisition Regulation Supplement. Pursuant to 48 C.F.R. § 12.212 (for civilian agencies) and 48 C.F.R. §§ 227.7202-1 through 227.7202-4 (for the Department of Defense), the Software is licensed to U.S. government end users (a) only as a commercial item and (b) with only those rights granted to all other end users under the standard commercial license terms in this EULA.
This EULA is governed by the laws of the State of Delaware, U.S.A., excluding its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply. If you are a consumer, nothing in this section deprives you of the protection afforded to you by mandatory provisions of the law of the country in which you have your habitual residence.
Before filing any formal dispute, you agree to first contact us at legal@adblocklabs.com and provide a brief written description of the dispute and the resolution you are seeking. We will attempt in good faith to resolve the dispute informally for at least 60 days after we receive your notice.
If you are a resident of the United States, you and Adblock Labs agree that any dispute, claim, or controversy arising out of or related to this EULA or the Software will be resolved by binding individual arbitration rather than in court, except as expressly provided below.
30-day right to opt out of arbitration. You may opt out of the arbitration agreement and class-action waiver in Section 18.3 by sending written notice to legal@adblocklabs.com within 30 days of first accepting this EULA. The notice must include your full name, mailing address, and a clear statement that you are opting out of arbitration. Opting out does not affect any other provision of this EULA.
For users who are not U.S. residents, and for U.S. users who have validly opted out of arbitration under Section 18.3, any dispute arising under this EULA shall be brought exclusively in the federal and state courts located in New Castle County, Delaware, U.S.A., and you and we submit to the personal jurisdiction of those courts. Nothing in this Section 18.4 limits any right you may have, as a consumer, to bring proceedings in the courts of the country in which you have your habitual residence, where applicable consumer-protection law gives you that right.
We may update this EULA from time to time. When we do, we will:
