Effective date: July 8, 2026 · GreerGuard by Dvance Development
These Terms of Service ("Terms") form a legally binding agreement between you ("you" or "User") and Dvance Development ("we," "us," or "Dvance"), the developer of the GreerGuard family of security products. Dvance Development is a sole proprietorship operating under the brand GreerGuard.
These Terms govern your access to and use of:
References to "GreerGuard" mean any or all of these products and services unless the context specifies otherwise.
You must be at least 13 years of age to use GreerGuard. If you are between 13 and 18 years of age, you may use GreerGuard only with the involvement and consent of a parent or legal guardian who agrees to be bound by these Terms on your behalf.
By using the Services you represent that:
Subject to these Terms, Dvance Development grants you a limited, non-exclusive, non-transferable, revocable license to install and use the free versions of GreerGuard on devices you own or control, solely for your personal, non-commercial security purposes.
The free Android application includes on-demand app behavior scanning. The browser extension and Firefox add-on are free in full and provide browser-trap detection, notification permission control, and deceptive-download blocking.
A paid subscription ("GreerGuardian") unlocks continuous background monitoring, real-time Notifications, DNS-based safe-browsing enforcement, and family device management across the number of seats purchased. Your subscription license is personal and may not be shared with individuals outside your household or family plan.
The license granted to you is for software only. No title to or ownership of the software or any intellectual property contained therein is transferred to you.
You may install the Android application on any Android device you personally own or control, up to the seat limit of your plan. You may install the browser extension on any browser profile you personally use. Redistribution, resale, or sub-licensing of either product outside of Dvance's authorized partner program is prohibited.
We may issue updates, patches, or new versions of GreerGuard at any time. You agree to accept such updates as part of continued use. Refusing updates may result in degraded or discontinued functionality.
GreerGuardian is billed on a recurring monthly or annual basis (depending on the plan selected) via Stripe. By subscribing you authorize us to charge your payment method on a recurring basis until you cancel. All prices are in US dollars and are exclusive of any applicable taxes, which are your responsibility.
Subscriptions renew automatically at the end of each billing period. You will be charged using the payment method on file unless you cancel before the renewal date. We will not provide advance notice before each renewal charge beyond the schedule disclosed at checkout.
Where a free trial is offered, no charge is made during the trial period. If you do not cancel before the trial ends, your subscription will convert to a paid plan and your payment method will be charged. We reserve the right to limit free trials to one per user or household.
We offer a 7-day money-back guarantee for new subscriptions. If you are unsatisfied within 7 days of your first charge, contact us and we will issue a full refund. After 7 days, subscription fees are non-refundable except where required by applicable law. Partial-month refunds are not issued for cancellations mid-period.
We may change subscription pricing with at least 30 days' advance notice delivered to the email address associated with your account. Continued use after the effective date of a price change constitutes acceptance of the new price.
If your subscription was purchased through an authorized GreerGuard partner or reseller, the partner's billing terms may apply alongside these Terms. Refund and cancellation rights for partner-distributed licenses are subject to the partner's policies; contact your partner for details.
You agree to use GreerGuard only for lawful purposes and in a manner consistent with these Terms. You must not:
Violations of this section may result in immediate termination of your license and, where appropriate, referral to law enforcement.
The GreerGuard Android application detects threats by analyzing app behavior, not by scanning files or device state. Specifically, the app identifies risk signals such as:
The GreerGuard browser extension detects browser-based threats including fullscreen-lock attacks, cursor-hiding techniques, exit-trap scripts, unauthorized notification permission requests, and deceptive download link disguises.
GreerGuard's risk assessments are informational. The presence or absence of a GreerGuard warning is not a guarantee that a given app or website is safe or malicious. You are responsible for your own security decisions. Do not rely solely on GreerGuard when evaluating software you install or websites you visit.
The SafeSearch DNS filter (GreerGuardian) routes DNS queries through a third-party resolver to block known malicious and adult domains. DNS filtering is not infallible; newly registered domains, fast-flux infrastructure, and encrypted direct connections may bypass DNS-level controls.
The browser extension operates within the permissions granted by the Chromium-based browser extension platform. Sites that use mechanisms not observable through standard browser APIs, or that exploit browser bugs, may not be detected. The extension does not inspect HTTPS traffic contents and does not function as a network proxy.
Your privacy matters to us. Our collection, use, and storage of your personal information is described in our Privacy Policy, which is incorporated into these Terms by reference. By using GreerGuard you acknowledge and agree to the Privacy Policy.
The Android application collects app metadata (package names, permission lists, installer source, and behavioral risk signals) to perform its analysis. It does not read file contents, message contents, or the substance of your communications. The browser extension processes page-level behavioral signals locally and does not transmit page content to our servers.
If you create an account or subscribe, we collect your email address, encrypted password, payment confirmation references, and subscription status. Payment card details are handled exclusively by Stripe and are never stored on Dvance servers.
We implement industry-standard technical and organizational measures to protect data we hold. No method of transmission or storage is 100% secure. In the event of a breach that affects your personal data, we will notify you as required by applicable law.
GreerGuard, the GreerGuard shield logo, GreerGuardian, and all associated product names, trademarks, trade dress, and branding are the exclusive property of Dvance Development. Nothing in these Terms grants you any right to use any Dvance trademark, logo, or brand feature without our prior written consent.
All software, algorithms, source code, design, and documentation comprising the GreerGuard products are protected by copyright and other intellectual property laws. All rights not expressly granted in these Terms are reserved by Dvance Development.
You retain ownership of any content you create or that exists on your device. GreerGuard does not claim any ownership over your data.
GreerGuard integrates with or relies upon third-party services including:
These third parties have their own terms of service and privacy policies, which govern their services. Dvance is not responsible for the practices of third-party services. You interact with them subject to their own terms.
We may change the third-party services we use at any time. If a change materially affects your experience, we will endeavor to communicate it in advance.
Dvance Development expressly disclaims all warranties, including but not limited to:
Some jurisdictions do not allow the exclusion of implied warranties, so some of the above exclusions may not apply to you. In such jurisdictions, our warranties are limited to the minimum scope required by law.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL DVANCE DEVELOPMENT, ITS OWNER, EMPLOYEES, CONTRACTORS, OR PARTNERS BE LIABLE TO YOU FOR ANY:
IN ALL CASES, OUR TOTAL AGGREGATE LIABILITY TO YOU FOR ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES SHALL NOT EXCEED THE GREATER OF (A) THE TOTAL FEES YOU PAID TO DVANCE DEVELOPMENT IN THE 12 MONTHS PRECEDING THE CLAIM, OR (B) $10.00 USD.
Some jurisdictions do not allow limitations on liability for death, personal injury, or fraudulent misrepresentation. Nothing in these Terms limits our liability for such matters where prohibited by law.
You agree to indemnify, defend, and hold harmless Dvance Development and its affiliates, officers, contractors, and partners from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or in any way connected with:
You may stop using GreerGuard at any time by uninstalling the software and, if applicable, canceling your subscription through your account portal. Cancellation stops future billing but does not entitle you to a refund of amounts already charged beyond the 7-day money-back window described in Section 4.4.
We may suspend or terminate your access to the Services, with or without notice, if:
In the event of termination for cause, no refund will be issued. In the event we discontinue the Services, we will provide reasonable advance notice and a pro-rated refund for any prepaid subscription period.
Upon termination, your license to use GreerGuard ends immediately. Sections 8, 10, 11, 12, 16, and 17 survive termination.
Authorized partners and affiliates who distribute GreerGuard licenses or refer customers are subject to a separate Partner Agreement in addition to these Terms. The Partner Agreement governs commission structure, permitted marketing representations, and co-branding rights.
Partners may not make claims about GreerGuard's capabilities that exceed what is stated in official product documentation. In particular, partners must not represent GreerGuard as an antivirus product or claim it scans files or guarantees complete threat elimination.
Affiliate codes and referral links are personal and non-transferable. Fraudulent use of affiliate codes is grounds for immediate termination of the partner relationship and forfeiture of any outstanding commissions.
We may update these Terms at any time. When we do, we will revise the effective date at the top of this page. For material changes, we will provide at least 14 days' notice via email or a prominent in-app notice before the updated Terms take effect.
Your continued use of GreerGuard after the effective date of revised Terms constitutes your acceptance of those Terms. If you disagree with a change, your remedy is to stop using the Services and cancel any active subscription before the change takes effect.
These Terms are governed by the laws of the State of Oregon, United States, without regard to its conflict-of-law provisions. Any dispute arising out of or relating to these Terms or the Services shall be resolved exclusively in the state or federal courts located in Oregon, and you consent to personal jurisdiction in those courts.
Before initiating any formal legal proceeding, you agree to contact us at the address below and give us 30 days to attempt to resolve the dispute informally. Nothing in this section prevents either party from seeking injunctive or equitable relief in any court of competent jurisdiction to protect intellectual property rights or prevent irreparable harm.
If you are a consumer resident of the European Union or United Kingdom, mandatory local consumer-protection laws may apply alongside these Terms and may provide you with additional rights. Nothing in these Terms limits rights you cannot waive under applicable consumer law.
These Terms, together with the Privacy Policy and any applicable Partner Agreement, constitute the entire agreement between you and Dvance Development regarding the Services and supersede all prior agreements and understandings.
If any provision of these Terms is found to be unenforceable or invalid, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force and effect.
Our failure to enforce any right or provision of these Terms shall not constitute a waiver of that right or provision. A waiver in one instance does not waive future enforcement of the same provision.
You may not assign or transfer your rights under these Terms without our prior written consent. We may assign our rights and obligations under these Terms without restriction, including in connection with a merger, acquisition, or sale of assets, provided that the acquiring party assumes our obligations under these Terms.
We are not liable for any failure or delay in performance resulting from causes outside our reasonable control, including natural disasters, government actions, internet infrastructure failures, or third-party service outages.
