Terms and Conditions

Effective Date: April 15, 2026
Last Updated: April 15, 2026

These Terms and Conditions (“Terms”) form a legally binding agreement between you (“you,” “your,” or “User”) and ViperBlock LLC, a Florida limited liability company (“ViperBlock,” “we,” “us,” or “our”), governing your access to and use of the ViperBlock WordPress security plugin in both Free and Pro editions (the “Plugin”), the viperblock.com website (the “Site”), and any related services, documentation, updates, and support (collectively, the “Service”).

BY DOWNLOADING, INSTALLING, ACTIVATING, ACCESSING, OR USING THE SERVICE, YOU ACKNOWLEDGE THAT YOU HAVE READ, UNDERSTOOD, AND AGREE TO BE BOUND BY THESE TERMS, INCLUDING THE BINDING ARBITRATION, CLASS ACTION WAIVER, LIMITATION OF LIABILITY, AND INDEMNIFICATION PROVISIONS BELOW. IF YOU DO NOT AGREE, DO NOT DOWNLOAD, INSTALL, OR USE THE SERVICE.

You represent that you are at least 18 years old and have the legal capacity to enter into these Terms. If you are using the Service on behalf of an organization, you represent that you are authorized to bind that organization.

1. Definitions

“Plugin” means the ViperBlock WordPress security plugin, including any updates, patches, and documentation, in Free or Pro editions.
“Pro” means the paid, subscription-based edition of the Plugin, activated by a valid License Key.
“Free” means the no-cost edition of the Plugin, distributed under GPL v2.
“License Key” means the unique alphanumeric key issued upon Pro purchase that authorizes activation of Pro features on a specific Site.
“Site” means a single WordPress installation identified by a unique primary domain.
“Subscriber” means a User who has purchased and holds an active Pro subscription.
“Content” means any data, files, text, or other material processed, stored, or transmitted by or through the Service.

2. License Grant

2.1 Free Edition

The Free edition is distributed under the GNU General Public License version 2 (GPL v2). You may use, modify, and redistribute the Free edition in accordance with GPL v2. The GPL v2 governs only the Plugin source code; these Terms continue to govern your use of the Site, the License Key system, and all Pro features.

2.2 Pro Edition

Subject to your payment of all applicable fees and your continued compliance with these Terms, ViperBlock grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use Pro on one (1) Site per License Key for the duration of your active Pro subscription. You may deactivate a License Key on one Site and activate it on another, subject to the reasonable-use and anti-abuse limits enforced by the license server.

2.3 Restrictions

You shall not, and shall not permit any third party to:

copy, modify, adapt, translate, or create derivative works of the Pro portions of the Plugin, except as expressly permitted by applicable law;
reverse engineer, disassemble, decompile, or otherwise attempt to derive the source code of any Pro-only component;
remove, alter, or obscure any proprietary notices, labels, or License Key verification mechanisms;
circumvent, disable, interfere with, or attempt to bypass the license verification system or any usage limits;
sublicense, rent, lease, lend, sell, resell, or distribute the License Key or Pro features;
use the Service in violation of any applicable law, regulation, or third-party right;
use the Service to transmit malware, conduct attacks, or harm any system or person.

Any breach of this Section 2.3 shall constitute a material breach of these Terms and may result in immediate revocation of your License Key and termination of your subscription without refund.

3. Free Trial

ViperBlock may, from time to time, offer a free trial of Pro features. Trials are provided without charge and without requiring a payment method unless expressly stated. At the end of a trial, the Plugin automatically reverts to the Free edition without data loss. ViperBlock reserves the right to modify or discontinue any trial offering at any time, and to revoke trial access where abuse is detected.

4. Fees, Billing, Auto-Renewal, and No Refunds

4.1 Fees

Pro is offered on an annual subscription basis at the price stated at the time of purchase. You authorize ViperBlock and its payment processor, Stripe, Inc. (“Stripe”), to charge your payment method for the initial purchase and for each subsequent annual renewal at the then-current price.

4.2 Auto-Renewal

Pro subscriptions automatically renew on each annual anniversary of your purchase date unless you cancel at least twenty-four (24) hours before the renewal date. You may cancel at any time through your account dashboard; cancellation takes effect at the end of your current billing period.

4.3 Price Changes

ViperBlock reserves the right to change subscription prices. Price changes apply to renewals on or after the effective date and will be communicated by email or on-site notice at least thirty (30) days in advance. Your continued use after the effective date constitutes acceptance of the new price.

4.4 NO REFUNDS

ALL SALES ARE FINAL. SUBSCRIPTION FEES ARE NON-REFUNDABLE, IN WHOLE OR IN PART, FOR ANY REASON, INCLUDING BUT NOT LIMITED TO UNUSED SUBSCRIPTION TIME, DISSATISFACTION WITH THE SERVICE, TECHNICAL ISSUES, LOSS OF ACCESS TO YOUR SITE, OR SUSPENSION OR TERMINATION OF YOUR ACCOUNT FOR CAUSE. You acknowledge and accept this no-refund policy as a material condition of your purchase. Before purchasing Pro, you are encouraged to install and evaluate the Free edition and any available trial to determine whether the Service meets your needs.

4.5 Chargebacks

If you initiate a chargeback or payment dispute without first contacting us in good faith, ViperBlock reserves the right to immediately suspend or revoke your License Key and terminate your account, and to recover any chargeback fees and reasonable collection costs from you.

4.6 Taxes

Fees are exclusive of sales tax, VAT, GST, and other taxes. You are responsible for any such taxes arising from your purchase.

5. Account Security

You are responsible for maintaining the confidentiality of your account credentials and License Key. You are solely responsible for all activity that occurs under your account. You must promptly notify us of any unauthorized use or suspected compromise of your credentials. ViperBlock is not liable for any loss or damage arising from your failure to safeguard your credentials.

6. Your Responsibilities — Essential Conditions of Use

You acknowledge and agree that the Plugin is a supplemental security layer, not a complete security solution, and that proper operation of the Plugin depends on conditions entirely within your control. As a condition of using the Service, you agree that you are responsible for:

keeping your WordPress core, themes, plugins (including the Plugin itself), and server software current with the latest security patches and updates;
maintaining complete, current, and tested backups of your Site, database, and files, stored off-site, on a schedule appropriate to your risk tolerance;
using strong, unique passwords and multi-factor authentication for all administrative accounts;
securing the hosting environment in which your Site runs, including server hardening, firewall rules, TLS configuration, and file permissions;
testing the Plugin in a non-production staging environment before deploying or updating it on a production Site;
reviewing and configuring the Plugin’s settings to match your specific security requirements, and understanding that default settings are provided as a starting point only;
monitoring the Plugin’s activity logs and responding to any alerts or anomalies;
complying with all laws applicable to the operation of your Site and the processing of data collected through it, including disclosing the Plugin’s local activity logging to your visitors where required by law;
maintaining and enforcing your own privacy policy, cookie notice, and consent flows as required by your jurisdiction.

Your failure to perform any of the above is not a breach of these Terms, but it is a circumstance for which ViperBlock bears no responsibility, and any harm arising from such failure is solely yours.

7. Security Software Disclaimer — IMPORTANT

YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT NO SECURITY SOFTWARE, INCLUDING THE PLUGIN, CAN GUARANTEE ABSOLUTE PROTECTION AGAINST ALL THREATS. Cybersecurity is an ever-evolving field, and attackers continuously develop new techniques. The Plugin provides a supplemental defensive layer designed to reduce — not eliminate — the risk of certain categories of attack. You acknowledge that:

the Plugin may fail to detect, prevent, or mitigate an attack;
zero-day vulnerabilities, targeted attacks, insider threats, supply-chain compromises, and novel attack vectors may bypass the Plugin entirely;
misconfiguration, outdated software, weak credentials, compromised hosting, or malicious third-party code may render the Plugin ineffective;
the Plugin’s effectiveness depends on your adherence to Section 6 above;
the Plugin is not a substitute for professional security assessment, incident response, or cyber insurance;
ViperBlock makes no representation that the Plugin will meet the requirements of any specific compliance regime (including PCI DSS, HIPAA, SOC 2, or GDPR) as a standalone measure.

The Plugin is one tool in a defense-in-depth strategy. It is not a warranty of security, and you must not rely on it as such.

8. Intellectual Property

The ViperBlock name, logo, trademarks, Site content, and all Pro-only portions of the Plugin are the exclusive property of ViperBlock LLC and are protected by United States and international intellectual property laws. Except for the limited license granted in Section 2, no rights are granted to you under these Terms, whether by implication, estoppel, or otherwise. The Free edition is licensed under GPL v2 as stated in Section 2.1; all other rights are reserved.

You retain all rights in Content that you process on your own Site using the Plugin. ViperBlock claims no ownership of such Content and, as described in the Privacy Policy, does not receive it.

9. Third-Party Services

The Service integrates with third-party services, including Stripe for payment processing and an email delivery provider for transactional email. Your use of any third-party service is governed by that provider’s own terms and privacy policy. ViperBlock is not responsible for the acts, omissions, failures, or security practices of any third-party service and disclaims all liability arising from them.

10. Availability and Support

10.1 Availability

ViperBlock will use commercially reasonable efforts to keep the license verification service and the Site available. However, ViperBlock does not guarantee uninterrupted or error-free availability. Scheduled maintenance, updates, infrastructure changes, and events beyond our reasonable control may cause temporary unavailability.

10.2 Support

Free users receive community support through public documentation. Pro subscribers receive priority email support during active subscriptions. ViperBlock will use commercially reasonable efforts to respond to Pro support requests within two (2) business days but does not guarantee any specific response or resolution time.

10.3 No SLA

ViperBlock does not offer and is not bound by any service level agreement for the Service or any component of it.

11. DISCLAIMER OF WARRANTIES

THE SERVICE, INCLUDING THE PLUGIN, THE SITE, ALL UPDATES, AND ALL RELATED MATERIALS, IS PROVIDED “AS IS,” “AS AVAILABLE,” AND “WITH ALL FAULTS.” TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, VIPERBLOCK AND ITS SUPPLIERS, LICENSORS, OFFICERS, MEMBERS, EMPLOYEES, AND AGENTS EXPRESSLY DISCLAIM ALL WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, SYSTEM INTEGRATION, QUIET ENJOYMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

VIPERBLOCK DOES NOT WARRANT THAT (a) THE SERVICE WILL MEET YOUR REQUIREMENTS; (b) THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE; (c) THE SERVICE WILL DETECT, PREVENT, OR MITIGATE ANY PARTICULAR ATTACK OR CATEGORY OF ATTACK; (d) DEFECTS IN THE SERVICE WILL BE CORRECTED; (e) THE SERVICE OR ANY SERVER ON WHICH IT IS HOSTED IS FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS; OR (f) ANY DATA OR CONTENT WILL BE PRESERVED OR RECOVERABLE.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you. In that case, the excluded warranties are limited to the minimum scope and duration permitted by applicable law.

12. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL VIPERBLOCK LLC, ITS MEMBERS, OFFICERS, EMPLOYEES, CONTRACTORS, AFFILIATES, LICENSORS, OR SUPPLIERS BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION DAMAGES FOR:

loss of profits, revenue, goodwill, use, or anticipated savings;
loss, corruption, destruction, or inaccessibility of data, files, Sites, or Content;
business interruption, downtime, or inability to operate a Site;
cost of substitute goods, services, or recovery;
damages arising from a security breach, intrusion, infection, defacement, ransom, data exfiltration, or unauthorized access;
damages arising from the Plugin failing to detect, prevent, or mitigate any attack, vulnerability, or exploit;
damages arising from reliance on the Plugin as a primary or sole security measure;
reputational harm, emotional distress, or loss of customer trust;

WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, WARRANTY, OR ANY OTHER LEGAL OR EQUITABLE THEORY, AND WHETHER OR NOT VIPERBLOCK HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

THE TOTAL AGGREGATE LIABILITY OF VIPERBLOCK LLC AND ITS AFFILIATES FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE, FROM ALL CAUSES OF ACTION AND UNDER ALL THEORIES OF LIABILITY, SHALL NOT EXCEED THE GREATER OF (i) ONE HUNDRED U.S. DOLLARS ($100) OR (ii) THE TOTAL AMOUNT YOU ACTUALLY PAID TO VIPERBLOCK FOR THE SERVICE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

THE LIMITATIONS IN THIS SECTION 12 ARE A FUNDAMENTAL ELEMENT OF THE BARGAIN BETWEEN YOU AND VIPERBLOCK AND APPLY EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE. You acknowledge that the Service would not be offered at the stated price without these limitations.

Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages. In those jurisdictions, ViperBlock’s liability is limited to the minimum extent permitted by applicable law.

13. Indemnification

You agree to indemnify, defend, and hold harmless ViperBlock LLC and its members, officers, employees, contractors, affiliates, licensors, and suppliers (the “Indemnified Parties”) from and against any and all claims, demands, actions, proceedings, damages, liabilities, losses, judgments, costs, and expenses (including reasonable attorneys’ fees and court costs) arising out of or related to:

your use or misuse of the Service;
your violation of these Terms or any policy incorporated by reference;
your violation of any applicable law, regulation, or third-party right;
your Content, your Site, or any activity occurring on or through your Site;
your failure to maintain backups, updates, or other responsibilities under Section 6;
any security incident on your Site, regardless of cause;
any claim by a visitor to, user of, or customer of your Site against ViperBlock arising from your operation of that Site or use of the Plugin;
any claim based on an allegation that the Plugin failed to protect your Site.

ViperBlock reserves the right, at your expense, to assume the exclusive defense and control of any matter subject to indemnification by you, in which case you agree to cooperate fully in the defense of the claim. You shall not settle any claim that imposes any obligation or liability on ViperBlock without ViperBlock’s prior written consent.

14. Termination

14.1 By You

You may terminate your use of the Free edition at any time by deactivating and uninstalling the Plugin. You may cancel your Pro subscription at any time through your account dashboard; the cancellation takes effect at the end of your current billing period, and no refund is due.

14.2 By ViperBlock

ViperBlock may suspend or terminate your access to any portion of the Service, including revoking your License Key, immediately and without notice, if ViperBlock reasonably determines that you have violated these Terms, engaged in abuse or fraud, initiated an unjustified chargeback, or created risk or legal exposure for ViperBlock. Termination for cause results in no refund.

14.3 Effect of Termination

Upon termination or expiration of Pro, your Site automatically reverts to the Free edition. Sections 2.3, 4.4, 4.5, 6, 7, 8, 11, 12, 13, 15, 16, and any other provision that by its nature should survive termination will survive.

15. Governing Law; Venue

These Terms and any dispute arising out of or relating to these Terms or the Service are governed by and construed in accordance with the laws of the State of Florida, United States of America, without regard to its conflict of laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Subject to Section 16, you and ViperBlock agree that any action or proceeding not subject to arbitration shall be brought exclusively in the state or federal courts located in Pinellas County, Florida, and each party irrevocably submits to the personal jurisdiction and venue of such courts and waives any objection based on forum non conveniens.

16. Binding Arbitration; Class Action Waiver

16.1 Agreement to Arbitrate

Except for the excluded matters described in Section 16.4, you and ViperBlock agree that any dispute, claim, or controversy arising out of or relating to these Terms, the Service, your account, or any aspect of your relationship with ViperBlock (a “Dispute”) shall be resolved by final and binding arbitration administered by the American Arbitration Association (“AAA”) in accordance with its Consumer Arbitration Rules then in effect. The arbitration shall be conducted in English before one (1) arbitrator and seated in Pinellas County, Florida, or at another location mutually agreed upon, or, where permitted by AAA rules, by video or telephone.

Judgment on the arbitrator’s award may be entered in any court of competent jurisdiction.

16.2 Class Action Waiver

YOU AND VIPERBLOCK AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, PRIVATE ATTORNEY GENERAL, OR REPRESENTATIVE ACTION OR PROCEEDING. The arbitrator may not consolidate more than one person’s claims, may not preside over any form of representative or class proceeding, and may award relief only in favor of the individual party seeking relief and only to the extent necessary to provide relief warranted by that party’s individual claim.

16.3 30-Day Opt-Out

You may opt out of this arbitration agreement by sending written notice of your decision to opt out to [email protected] within thirty (30) days of first accepting these Terms. The notice must include your full name, address, email associated with your account, and a clear statement that you wish to opt out of arbitration. Opting out will not affect any other provision of these Terms.

16.4 Excluded Matters

Notwithstanding the foregoing, either party may (a) bring an individual action in small claims court, (b) seek injunctive or other equitable relief in a court of competent jurisdiction to prevent the actual or threatened infringement, misappropriation, or violation of intellectual property or license-verification rights, or (c) pursue any claim that is not subject to arbitration under applicable law.

16.5 Survival and Severability

This Section 16 survives termination of these Terms. If any portion of this Section 16 is held invalid or unenforceable, that portion shall be severed and the remainder shall remain in full force, except that if the class action waiver in Section 16.2 is held unenforceable as to any claim for public injunctive relief, that claim (and only that claim) shall be severed from arbitration and brought exclusively in the courts identified in Section 15.

17. Force Majeure

ViperBlock shall not be liable for any failure or delay in performance under these Terms caused by events beyond its reasonable control, including acts of God, natural disasters, war, terrorism, riots, civil unrest, pandemics, government actions, labor disputes, power or internet outages, cyberattacks, failures of upstream providers or data centers, or any other force majeure event.

18. Export Controls and Sanctions

You represent and warrant that (a) you are not located in any country that is subject to a comprehensive U.S. embargo or designated as a “terrorist supporting” country, and (b) you are not on any U.S. government list of prohibited or restricted parties. You agree not to use or export the Service in violation of U.S. export laws or sanctions.

19. Assignment

You may not assign or transfer these Terms or any of your rights or obligations under them, by operation of law or otherwise, without ViperBlock’s prior written consent. ViperBlock may assign these Terms, in whole or in part, at any time, without notice or consent.

20. Modifications to the Terms

ViperBlock may modify these Terms from time to time. Material changes will be communicated by email to your account address and/or by prominent notice on the Site at least thirty (30) days before they take effect. Non-material changes may take effect upon posting. Your continued use of the Service after the effective date of any change constitutes your acceptance of the modified Terms. If you do not agree to a change, your sole remedy is to stop using the Service before the change takes effect.

21. Notices

ViperBlock may provide notices to you by email, by posting on the Site, or through the Plugin’s admin interface. You must provide notices to ViperBlock by email to [email protected]. Notices are deemed given upon receipt, or, for email, twenty-four (24) hours after sending unless the sender receives a non-delivery notification.

22. Severability

If any provision of these Terms is held invalid, illegal, or unenforceable by a court of competent jurisdiction or an arbitrator, that provision shall be enforced to the maximum extent permitted by law, and the remaining provisions shall remain in full force and effect.

23. No Waiver

No failure or delay by ViperBlock in exercising any right under these Terms shall operate as a waiver of that right. No waiver of any term of these Terms shall be deemed a further or continuing waiver of that or any other term.

24. Entire Agreement

These Terms, together with the Privacy Policy and any other policies expressly incorporated by reference, constitute the entire agreement between you and ViperBlock concerning the Service and supersede all prior or contemporaneous agreements, representations, and understandings, whether written or oral.
