Terms of Service

Last updated: March 8, 2026

Welcome to Sentinel, operated by CMTOC ("Company", "we", "us", "our"). These Terms of Service ("Terms") govern your access to and use of the Sentinel platform, including our website, APIs, and related services (collectively, the "Service"). By creating an account or using the Service, you agree to be bound by these Terms. If you do not agree to these Terms, do not use the Service.

1. Acceptance of Terms

By accessing or using the Service, you confirm that you are at least 18 years old (or the age of majority in your jurisdiction) and have the legal authority to enter into these Terms. If you are using the Service on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms, and "you" refers to both you individually and the organization.

2. Account Registration

  • You must provide accurate, complete, and current information when creating an account.
  • You are responsible for maintaining the confidentiality of your account credentials, including passwords, API keys, and two-factor authentication codes.
  • You are responsible for all activities that occur under your account, whether or not authorized by you.
  • You must notify us immediately of any unauthorized use of your account.
  • We reserve the right to suspend or terminate accounts at our sole discretion (see Section 14).
  • One person or entity may not maintain more than one free account.

3. Service Description

Sentinel provides uptime monitoring, incident management, status pages, and related services for websites, APIs, and infrastructure. Features vary by subscription tier.

  • We may modify, update, add, or remove features at any time, with or without notice.
  • We may impose or adjust usage limits, rate limits, check intervals, data retention periods, and other technical restrictions at any time.
  • The Service is provided by a small team and is under active development. Features may change, and service interruptions may occur.

4. Service Availability and Accuracy Disclaimer

The Service is provided on an "as is" and "as available" basis. While we strive for reliability, you acknowledge and agree that:

  • We do not guarantee that the Service will detect every outage, incident, or performance degradation affecting your monitored targets.
  • Monitoring results, response times, uptime calculations, and alert notifications may be delayed, inaccurate, or incomplete.
  • False positives and false negatives in monitoring checks may occur.
  • Alert delivery (email, Slack, webhook, SMS, or other channels) is best-effort and not guaranteed.
  • AI-generated incident analyses, root cause reports, and suggested actions are informational only and may be inaccurate. You must not rely solely on AI features for critical decisions.
  • You are solely responsible for maintaining your own independent monitoring, backup systems, and incident response procedures.
  • The Service is not designed or intended as a sole or primary monitoring solution for life-safety, medical, financial trading, or critical infrastructure systems where failure to detect an outage could result in death, injury, or significant financial loss.

5. Subscription Plans and Billing

  • Free accounts are subject to the limitations of the Free tier as described on our pricing page. We may modify Free tier limits at any time.
  • Paid subscriptions are billed monthly in advance via Stripe. Prices are as listed at the time of purchase.
  • You may upgrade, downgrade, or cancel your subscription at any time through your account settings. Downgrades take effect at the next billing cycle.
  • No refunds. All fees are non-refundable except where required by applicable law. This includes partial months, unused time, and downgrades.
  • We reserve the right to change pricing at any time. Price changes for existing paid subscribers take effect 30 days after notice. If you do not agree to the new pricing, you may cancel before the new price takes effect.
  • If payment fails, we may suspend your account after a grace period. Continued non-payment may result in account termination and data deletion.

6. Acceptable Use

You agree not to:

  • Use the Service to monitor targets you do not own or have explicit authorization to monitor.
  • Use the Service to conduct denial-of-service attacks, vulnerability scanning, penetration testing, or any form of abuse against third-party systems.
  • Attempt to gain unauthorized access to the Service, other user accounts, or related systems.
  • Reverse engineer, decompile, disassemble, or attempt to derive the source code of any part of the Service.
  • Resell, sublicense, or redistribute access to the Service without our prior written permission.
  • Use the Service in violation of any applicable law or regulation.
  • Transmit malware, viruses, or other harmful code through the Service.
  • Circumvent rate limits, usage quotas, bot protection, or other technical restrictions.
  • Use automated means (bots, scrapers, crawlers) to access the Service except through our documented API.
  • Use the Service in a manner that places unreasonable load on our infrastructure.

We reserve the right to determine, in our sole discretion, what constitutes a violation of this section. Violations may result in immediate suspension or termination without notice.

7. Data and Privacy

Your use of the Service is also governed by our Privacy Policy, which describes how we collect, use, and protect your data. You retain ownership of all data you submit to the Service. We will not sell your personal data to third parties.

You are responsible for the legality of the data you submit to the Service and for obtaining any necessary consents from third parties whose data may be processed through your use of the Service (e.g., status page subscribers).

You are granted a limited, non-exclusive, non-transferable, revocable license to use the Service in accordance with these Terms. This license does not include the right to modify, distribute, or create derivative works of the Service.

We may use your company name and logo on our website and marketing materials as a customer reference, unless you opt out by contacting us.

9. API Usage

  • Access to the Sentinel API is subject to rate limits and usage quotas based on your subscription tier.

  • We may modify or deprecate API endpoints with reasonable notice. We are not responsible for disruptions caused by API changes.

10. Third-Party Integrations

The Service may integrate with third-party services (e.g., Stripe, Slack, Discord, PagerDuty, GitHub, Google). Your use of third-party services is subject to their respective terms and privacy policies. We are not responsible for the availability, accuracy, security, or conduct of third-party services. Third-party service outages may affect Service functionality, and we are not liable for such disruptions.

15. Dispute Resolution and Arbitration

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT.

Informal Resolution

Before filing any formal dispute, you agree to contact us at [email protected] and attempt to resolve the dispute informally for at least 30 days.

Binding Arbitration

If we cannot resolve the dispute informally, any dispute, claim, or controversy arising from or relating to these Terms or the Service shall be resolved by binding arbitration administered in accordance with the rules of the American Arbitration Association ("AAA"). Arbitration shall take place in the State of Texas, United States, or remotely by mutual agreement. The arbitrator's decision shall be final and binding.

Class Action Waiver

YOU AGREE THAT ANY DISPUTE RESOLUTION PROCEEDINGS WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. If for any reason a claim proceeds in court rather than arbitration, you waive any right to a jury trial.

Small Claims Exception

Notwithstanding the above, either party may bring an individual action in small claims court for disputes within the court's jurisdictional limits.

16. Force Majeure

We shall not be liable for any failure or delay in performing our obligations under these Terms due to causes beyond our reasonable control, including but not limited to: natural disasters, acts of war or terrorism, pandemics, labor disputes, government actions, internet or telecommunications failures, power outages, DDoS attacks or other cyberattacks, third-party service provider failures (including cloud hosting, DNS, CDN, or payment processors), or any other force majeure event. During any such period, our obligations shall be suspended without liability.

17. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of Texas, United States, without regard to conflict of law principles. To the extent litigation is permitted under these Terms, you consent to the exclusive jurisdiction and venue of the state and federal courts located in Texas.

18. General Provisions

Entire Agreement

These Terms, together with the Privacy Policy and any other policies referenced herein, constitute the entire agreement between you and the Company regarding the Service, superseding all prior agreements, communications, and understandings.

Severability

If any provision of these Terms is found to be invalid, illegal, or unenforceable by a court of competent jurisdiction, the remaining provisions shall remain in full force and effect. The invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable.

Waiver

Our failure to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver must be in writing and signed by the Company.

Assignment

You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign these Terms, in whole or in part, at any time without notice, including in connection with a merger, acquisition, reorganization, or sale of assets.

No Third-Party Beneficiaries

These Terms do not create any third-party beneficiary rights in any individual or entity.

19. Changes to Terms

We may update these Terms at any time. We will notify you of material changes via email or through the Service at least 15 days before they take effect. Your continued use of the Service after the updated Terms take effect constitutes your acceptance of the revised Terms. If you do not agree to the updated Terms, you must stop using the Service and close your account.
