Terms of Service.

These Terms of Service govern your access to and use of the LogosGuard AI Privacy Shield browser extension and related services. Last updated: June 12, 2026.

These Terms of Service ("Terms") are a legal agreement between you ("you" or "User") and 550 Ventures, Inc. d/b/a LogosGuard, a Delaware corporation ("LogosGuard," "we," "us," or "our"), governing your access to and use of the LogosGuard "AI Privacy Shield" browser extension, the websites at logosguard.com, and related software and services (collectively, the "Service").

By installing, accessing, or using the Service, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference. If you do not agree, do not install or use the Service.

These Terms cover the consumer AI Privacy Shield extension only. Any LogosGuard enterprise, server-side, or cloud offering is governed by a separate written agreement.

1. Eligibility

You must be at least 18 years old and able to form a binding contract to use the Service. If you use the Service on behalf of an organization, you represent that you are authorized to bind that organization to these Terms.

2. The Service; What It Is and Is Not

The Service is an assistive tool that runs on your device to help you detect and redact certain categories of potentially sensitive information ("PII") in text and files before you choose to submit them to third-party AI services (such as ChatGPT, Claude, Gemini, Copilot, Grok, and Perplexity).

You acknowledge and agree that:

What you acknowledge.

  • The Service performs automated, best-effort detection using machine-learning models and pattern matching. It is not exhaustive, not deterministic, and not guaranteed to identify or remove all sensitive information.
  • The Service is a supplementary safeguard, not a substitute for your own review and judgment. A review step is provided so that you can inspect and confirm what is sent.
  • You decide what is ultimately submitted. The Service does not control, and is not responsible for, what you choose to send to any third-party service.

3. No Guarantee of Detection or Redaction; Your Responsibility

No detection or redaction system is perfect. The Service may produce false negatives (failing to flag or redact sensitive information) and false positives (flagging or redacting non-sensitive information). Detection quality depends on the content, file type, formatting, language, and other factors outside our control.

You are solely responsible for the content you submit to any third-party service, and for reviewing the Service's output before submitting. You should not rely on the Service as your sole or primary control for protecting sensitive, confidential, or regulated information. If information must not be disclosed, do not transmit it.

4. Accounts and Authentication

Certain features (including paid plans) may require an account, which you may create or access through logosguard.com using a third-party authentication provider. You are responsible for maintaining the confidentiality of your credentials and for all activity under your account. Notify us promptly at security@logosguard.com of any unauthorized use.

5. Plans, Free Trials, Billing, and Cancellation

Free and paid plans. The Service may be offered with a free tier (subject to usage limits) and one or more paid subscription plans ("Pro") that unlock additional features. Current features and limits are described in the Service or on our website and may change.

Free trial. We may offer a time-limited free trial of 7 days. Unless you cancel before the trial ends, the trial automatically converts to a paid subscription and your payment method will be charged.

Billing and auto-renewal. Paid plans are billed on a recurring basis (monthly or annually) through our third-party payment processor, Stripe. Subscriptions automatically renew for successive periods at the then-current price until cancelled. By subscribing, you authorize recurring charges.

Price changes. We may change prices or plan features prospectively; we will provide notice as required by law, and changes take effect on your next billing cycle.

Cancellation. You may cancel at any time through your account settings at logosguard.com/account. Cancellation stops future renewals; access continues until the end of the current paid period.

Refunds. Except as required by applicable law, fees are non-refundable and partial periods are not prorated.

Taxes. Fees are exclusive of taxes; you are responsible for applicable taxes other than taxes on our net income.

6. License

Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Service for your own lawful use. We reserve all rights not expressly granted.

7. Acceptable Use

You agree not to, and not to permit anyone to:

Prohibited uses.

  • use the Service in violation of any law or the terms of any third-party service (including the AI platforms you interact with);
  • reverse engineer, decompile, or disassemble the Service, except to the extent that restriction is prohibited by applicable law;
  • circumvent or interfere with usage limits, license validation, security, or rate-limiting;
  • resell, rent, or commercially redistribute the Service without our written permission;
  • use the Service to build a competing product, or to harm, harass, or infringe the rights of others;
  • introduce malware or attempt to gain unauthorized access to the Service or related systems.

8. Privacy and Data

The consumer Service is designed to perform detection and redaction locally on your device. Our handling of information is described in the Privacy Policy. You are responsible for ensuring that your use of the Service complies with any obligations you have regarding the data you process.

9. Intellectual Property

The Service, including its software, design, and "LogosGuard" and "AI Privacy Shield" names and logos, is owned by LogosGuard or its licensors and is protected by intellectual-property laws. The Service may incorporate third-party and open-source components (including machine-learning models such as openai/privacy-filter), which are subject to their own license terms; nothing here limits your rights or our obligations under those licenses.

10. Third-Party Services

The Service interoperates with third-party services (AI platforms, payment processing, authentication). We do not control and are not responsible for those services, their availability, or their handling of your data. Your use of them is governed by their own terms and privacy policies.

11. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, LOGOSGUARD DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

WITHOUT LIMITING THE FOREGOING, LOGOSGUARD DOES NOT WARRANT THAT THE SERVICE WILL DETECT, IDENTIFY, REDACT, OR PREVENT THE DISCLOSURE OF ANY PARTICULAR INFORMATION; THAT IT WILL BE ACCURATE, COMPLETE, UNINTERRUPTED, SECURE, OR ERROR-FREE; OR THAT IT WILL MEET YOUR REQUIREMENTS.

The Service is not certified, audited, or warranted to be compliant with HIPAA/HITECH, GDPR, CCPA/CPRA, or any other law, regulation, or standard. You are solely responsible for determining whether the Service is appropriate for your use and for your own legal and regulatory compliance. Do not use the consumer Service to process protected health information or other regulated data in reliance on it as a compliance control.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you.

12. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW:

(a) IN NO EVENT WILL LOGOSGUARD OR ITS OFFICERS, DIRECTORS, EMPLOYEES, OR SUPPLIERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS INTERRUPTION, OR FOR ANY UNAUTHORIZED ACCESS TO OR DISCLOSURE OF DATA OR INFORMATION (INCLUDING SENSITIVE INFORMATION NOT DETECTED OR REDACTED BY THE SERVICE), ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

(b) LOGOSGUARD'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (i) THE AMOUNTS YOU PAID TO LOGOSGUARD FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (ii) US$100.

These limitations are a fundamental basis of the bargain. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

13. Indemnification

You will indemnify, defend, and hold harmless LogosGuard and its affiliates, officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your use of the Service; (b) the content or data you process or submit using the Service; (c) your violation of these Terms or applicable law; or (d) your violation of the rights of any third party.

14. Termination

You may stop using and uninstall the Service at any time. We may suspend or terminate your access at any time, with or without notice, including for violation of these Terms or to comply with law. Upon termination, the license in Section 6 ends. Sections 3, 9, and 11–18 (and any others that by their nature should survive) survive termination.

15. Changes to the Service and to These Terms

We may modify, suspend, or discontinue all or part of the Service at any time. We may also update these Terms; if we make material changes, we will provide reasonable notice (e.g., by posting the updated Terms with a new "Last updated" date or via the Service). Your continued use after the changes take effect constitutes acceptance.

16. Governing Law; Dispute Resolution

These Terms are governed by applicable law, without regard to conflict-of-laws rules. The governing law, the venue, and the method of resolving any dispute — whether through the courts or by binding arbitration — are not fixed in advance by these Terms; instead, You and LogosGuard will decide and agree on them. Until You and LogosGuard agree otherwise, You and LogosGuard will work together in good faith to resolve any dispute arising out of or relating to the Service or these Terms.

17. Export and Sanctions Compliance

You represent that you are not located in, and will not use the Service in, any jurisdiction subject to comprehensive sanctions, and that you are not on any restricted-party list.

18. Miscellaneous

These Terms (with the Privacy Policy and any plan-specific terms) are the entire agreement between you and LogosGuard regarding the Service. If any provision is held unenforceable, the remaining provisions remain in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. We are not liable for delays or failures caused by events beyond our reasonable control.
