Terms of Service

Last updated: July 11, 2026

These Terms of Service ("Terms") govern access to and use of the StackEye services provided by Mattox Engineering LLC, doing business as StackEye ("StackEye," "we," "us," or "our"). By accessing or using StackEye, you agree to these Terms on behalf of yourself and, if applicable, the organization you represent. These Terms incorporate by reference the StackEye Privacy Policy, Cookie Policy, Data Processing Agreement, and Service Level Agreement.

1. The Services

StackEye provides uptime monitoring, probe execution, alerting, status pages, dashboards, APIs, command-line tools, private relay components, and related services (the "Services"). The Services may include hosted software, downloadable agents, documentation, support, and integrations.

We may update, improve, suspend, or discontinue parts of the Services, subject to any separate written agreement we have with you.

2. Eligibility and Authority

You must be at least 18 years old to use the Services. If you use the Services for an organization, you represent that you have authority to bind that organization to these Terms.

3. Accounts and Organizations

You are responsible for:

• providing accurate account and billing information;
• maintaining the confidentiality of passwords, API keys, tokens, private relay credentials, and other authentication materials;
• all activity under your account or organization;
• promptly notifying us of unauthorized access or suspected credential compromise;
• ensuring organization administrators and team members use the Services in compliance with these Terms.

We may suspend or restrict accounts that we believe are compromised, abusive, unlawful, or in violation of these Terms.

4. Authorized Monitoring

You may use StackEye to monitor systems, URLs, domains, IP addresses, services, and infrastructure only where you have legal authority to do so.

You are responsible for the targets, regions, checks, payloads, headers, labels, alert content, and other configuration you submit. You must not use StackEye to scan, probe, attack, overload, bypass controls, or collect information from systems you do not own or have authorization to test.

Private relay and internal monitoring features may be used only for networks and systems you are authorized to monitor.

5. Acceptable Use

You must not:

• violate applicable law or third-party rights;
• use the Services for malware, phishing, credential theft, spam, denial-of-service activity, scraping, unauthorized vulnerability scanning, or abusive automation;
• interfere with the integrity, security, or performance of the Services;
• attempt to bypass usage limits, authentication, authorization, billing, rate limits, or security controls;
• reverse engineer hosted portions of the Services except where applicable law expressly permits;
• submit sensitive regulated data unless we have expressly agreed in writing;
• use the Services to send unlawful, deceptive, or abusive notifications;
• resell or provide the Services to third parties except as permitted in a written agreement.

We may investigate suspected violations and may suspend, disable, or remove offending monitors, integrations, accounts, or organizations.

6. Customer Data

"Customer Data" means data, content, configuration, telemetry, monitor targets, probe results, status page content, and other materials you submit to or generate through the Services.

You retain ownership of Customer Data. You grant StackEye the rights needed to host, process, transmit, analyze, secure, display, and otherwise use Customer Data to provide, support, protect, and improve the Services.

You represent that you have all rights and permissions needed to provide Customer Data to StackEye and to allow StackEye to process it as described in these Terms, the Privacy Policy, and any applicable Data Processing Agreement.

7. StackEye Technology

We and our licensors own the Services, software, documentation, website, interfaces, designs, trademarks, logos, and other StackEye technology. Except for the limited right to use the Services under these Terms, no rights are transferred to you.

You may not remove proprietary notices, copy hosted software, or use StackEye names or marks in a way that suggests endorsement without our prior written permission.

8. Feedback

If you send suggestions, ideas, bug reports, or feedback, you grant us a perpetual, irrevocable, worldwide, royalty-free right to use it without restriction or compensation.

9. Third-Party Services and Integrations

The Services may connect to third-party services, including payment processors, notification providers, identity providers, cloud providers, incident management tools, and collaboration platforms. Your use of third-party services is governed by their terms and policies.

We are not responsible for third-party services, even when they are linked or integrated with StackEye.

10. Subscriptions, Trials, and Payment

Paid plans are billed through Stripe. You authorize us and our payment processor to charge applicable fees, taxes, and recurring subscription amounts using the payment method you provide.

Subscription terms, limits, included usage, trial periods, renewal dates, and prices are shown in the product, order flow, invoice, or written agreement. Unless stated otherwise, subscriptions renew automatically until canceled.

You are responsible for taxes other than taxes based on our net income. Fees are non-refundable except where required by law or expressly stated in a written agreement.

We may change plan features or prices prospectively. If a price change affects an active paid subscription, we will provide notice where required by law or contract.

11. Usage Limits

Plans may include limits on monitors, regions, check intervals, users, status pages, notification volume, API calls, retention, private regions, or other usage. We may enforce technical limits, throttle usage, require plan changes, or suspend excessive use that degrades the Services.

12. Service Availability and Support

We work to provide reliable Services, but we do not guarantee uninterrupted or error-free operation. StackEye uses commercially reasonable efforts to keep the Services available for all plans. For Enterprise customers, StackEye provides a numeric uptime commitment and service-credit remedy as set out in the Service Level Agreement (service-level-agreement.md), which is incorporated into these Terms. The Free, Starter, Pro, and Team plans receive commercially reasonable efforts but no numeric service level agreement and no service credits.

Maintenance, outages, third-party failures, network issues, customer configuration, and force majeure events may affect availability. Support channels and response targets may vary by plan.

13. Beta and Preview Features

Beta, preview, experimental, or evaluation features are provided "as is," may change or be discontinued at any time, and may be excluded from service level or support commitments.

14. Privacy and Data Processing

Our Privacy Policy explains how we collect and process personal information. If StackEye processes personal data on behalf of a customer as a processor, the Data Processing Agreement applies where required.

15. Security

We use reasonable technical and organizational measures designed to protect the Services. You are responsible for secure configuration of your account, integrations, API keys, webhooks, private relay deployments, and monitored targets.

You must promptly report suspected vulnerabilities or security incidents affecting StackEye to security@stackeye.io or legal@stackeye.io.

16. Suspension and Termination

You may stop using the Services or cancel a subscription according to the cancellation process in the product or billing portal.

We may suspend or terminate access if:

• you breach these Terms;
• fees are overdue;
• your use creates security, legal, operational, or reputational risk;
• we are required to do so by law;
• your account has been inactive for an extended period and notice has been provided where required.

After termination, you may lose access to the Services and Customer Data. We may delete or retain data according to our retention schedules, legal obligations, and backup lifecycle practices.

17. Disclaimers

The Services are provided "as is" and "as available." To the maximum extent permitted by law, we disclaim warranties of merchantability, fitness for a particular purpose, title, non-infringement, uninterrupted operation, error-free operation, and accuracy of results.

StackEye is an operational monitoring tool. It does not replace your own incident response, security monitoring, compliance program, backups, disaster recovery, or business continuity obligations.

18. Limitation of Liability

To the maximum extent permitted by law, StackEye will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, revenue, goodwill, data, or business interruption.

To the maximum extent permitted by law, StackEye's aggregate liability for all claims relating to the Services or these Terms will not exceed the amounts paid by you to StackEye for the Services giving rise to the claim during the 12 months before the event giving rise to liability, or USD $100 if you have not paid any fees.

Some jurisdictions do not allow certain limitations, so some limitations may not apply.

19. Indemnification

You will defend, indemnify, and hold harmless StackEye and its owners, employees, contractors, and agents from claims, damages, liabilities, costs, and expenses, including reasonable attorneys' fees, arising from:

• your use of the Services;
• Customer Data;
• monitored targets or systems;
• your breach of these Terms;
• your violation of law or third-party rights.

20. Changes to These Terms

We may update these Terms from time to time. Updated Terms will be posted with a new "Last updated" date. If changes materially affect your rights or obligations, we will provide additional notice where required.

Your continued use of the Services after changes become effective means you accept the updated Terms.

21. Governing Law and Venue

These Terms are governed by the laws of the State of Illinois, United States, without regard to conflict-of-law rules. Subject to any required alternative dispute process, disputes will be brought in the state or federal courts located in Illinois, and each party consents to personal jurisdiction and venue there.

22. Miscellaneous

These Terms, together with any order, DPA, policy, or written agreement that references them, are the entire agreement between you and StackEye for the Services. If any provision is unenforceable, the remaining provisions remain in effect. You may not assign these Terms without our consent, except as part of a merger, acquisition, or sale of substantially all assets. We may assign these Terms in connection with a merger, acquisition, reorganization, or sale of assets.

Our failure to enforce a provision is not a waiver.
