Terms of use

1. What Critical Line does

Critical Line identifies communications lines a building depends on, assesses which of them are exposed to carrier network changes, and manages the transition to a replacement path. Typical endpoints include elevator emergency phones, fire alarm communicators, emergency phones, security and gate systems, and specialty analog services.

We are a services company. We are not a telecommunications carrier, we are not your alarm monitoring provider, and we do not act as your Authority Having Jurisdiction. Where those parties are involved, we coordinate with them; we do not replace them.

2. Carrier information on this site

The carrier retirement information published on this site is summarized from public carrier disclosures. We show what a carrier has filed, the market it names, the dates attached to it, and a link to the underlying document wherever the source permits.

This information is provided for general awareness. A notice naming your market does not establish that any specific line at your property will be disconnected, and the absence of a notice does not establish that a line is safe. Carrier timelines change, filings are amended, and coverage of any public data set is incomplete.

The property check on this site matches an address against the notices we hold. It returns a market-level signal in most cases, and it labels the precision of every result. It is a starting point for a conversation, not a determination about your service.

You should not make a disconnection, procurement or compliance decision on the basis of this site alone. A Critical Line assessment verifies the actual service and dependency at your property.

3. Estimates, quotes and pricing

Any plan, inventory, recommended path or number produced before a verified quote is budgetary. It reflects the information available at that moment and the assumptions recorded alongside it.

Firm pricing comes with a verified quote issued after technical review. Where an estimate and a verified quote disagree, the verified quote governs.

Nothing is ordered, provisioned or installed automatically. Work begins only after you authorize it.

• Estimates exclude inside wiring repair unless stated.
• Estimates exclude permit fees and any fees charged by an Authority Having Jurisdiction.
• Life-safety lines are priced as a range until the panel, signaling method and local requirements are verified.
• Third-party charges, including carrier and vendor charges, are passed through as incurred unless the written agreement says otherwise.

4. Life-safety systems and code approval

Elevator emergency phones, fire alarm communicators and similar endpoints are life-safety systems. Requirements for them depend on the specific installation, the equipment in place, the adopted code edition and the Authority Having Jurisdiction for your site.

We do not promise that any solution will be approved before the actual site, equipment and local requirements have been reviewed. Any vendor who promises universal approval without that review is guessing. We design the project around the requirements that actually apply, and we coordinate testing and documentation.

Existing service is released only after the replacement path is installed, tested, accepted and authorized for release by you in writing. If you direct us to release a line earlier, you accept the consequences of doing so.

You remain responsible for your own regulatory and code obligations, for inspections, and for maintaining the systems themselves.

5. Your responsibilities

The quality of the work depends on the accuracy of what you give us. You agree to provide information that is accurate to the best of your knowledge, and to tell us when it changes.

• You confirm you have the right to share the bills, notices, inventories, site information and building documents you upload.
• You will provide reasonable site access and coordinate the vendors and staff we need to work with.
• You will keep your account credentials confidential and tell us promptly if you believe an account has been compromised.
• You will not upload malicious files, attempt to access another organization's data, probe or disrupt the service, scrape it in bulk, or use it to build a competing data set.

6. Accounts and the customer portal

The portal holds your properties, line inventory, documents, projects and messages. Access is scoped to your organization, and you control who you invite and what role they hold.

An organization owner can add and remove members, and can export or delete the organization's data. Anyone you invite can see the organization's information according to the role you assign, so invite deliberately.

We may suspend an account that is being used in a way that threatens the security or integrity of the service, or that violates these terms. Where circumstances allow, we will tell you first.

7. Your data and confidentiality

Documents and property information you provide remain yours. We treat them as confidential customer data from the moment they are uploaded, and we handle them as described in the confidentiality commitment and privacy statement on this page.

We will not share your documents or their contents with a vendor, carrier or other third party without your permission, we do not sell them, and we do not use them to train public artificial intelligence models. Your property and line information does not appear on any public map or data set.

You grant us permission to use the information you provide only to deliver the service to you: building your inventory, assessing exposure, planning and managing migrations, and supporting your account.

You can export your data or request permanent deletion at any time from the portal. Deletion is honored across backups on the published schedule and is not reversible after the stated grace period.

8. Meetings booked through this site

Booking a meeting reserves time with a specialist. It does not create a project, a price or an obligation on either side.

You can cancel from the link in your confirmation. We may need to reschedule occasionally, and we will give you as much notice as we can.

9. Communications

When you give us your email address, you agree that we may contact you about the property, project or meeting it relates to. If you ask to be alerted about carrier activity for a property, you agree to receive those alerts.

You can opt out of marketing messages at any time. Messages about work in progress, safety-relevant carrier activity affecting your properties, and account or security matters are part of the service and are not marketing.

10. Intellectual property

The site, the portal, the Critical Line name and mark, and the methodology, software and carrier intelligence behind them belong to us. You may use them to evaluate and receive the service, and not for anything else.

Deliverables prepared specifically for you, including your line inventory, assessment and migration plan, are yours to use for your own purposes once paid for under the applicable agreement. The underlying tools, templates and data sets used to produce them remain ours.

Feedback you send us may be used to improve the service without obligation to you.

11. Disclaimers

The site and the information on it are provided as is. We do not warrant that the carrier information is complete, current or uninterrupted, that the site will always be available, or that a result from the property check will match what a carrier ultimately does.

Services we perform under a signed agreement carry whatever warranties that agreement states. These terms do not add to or replace them.

Nothing here is legal, regulatory or engineering advice for your specific situation.

12. Limitation of liability

To the extent the law allows, we are not liable for indirect, incidental, special or consequential damages, or for lost profits, lost business or loss of data, arising from your use of this site or its information.

To the extent the law allows, our total liability arising out of your use of this site is limited to one hundred United States dollars. Liability for services performed under a signed agreement is governed by that agreement.

Nothing in these terms limits liability that cannot be limited by law, including liability for fraud, or for death or personal injury caused by negligence.

13. Indemnity

You agree to defend and indemnify us against claims arising from information you provided that you did not have the right to share, from your misuse of the site, or from your breach of these terms.

14. Changes to the service and these terms

We may change the site and these terms. When a change is material, we will update the effective date at the top of this page, and we will tell account holders directly. Continuing to use the site after a change means you accept the updated terms.

15. Governing law and disputes

These terms are governed by the laws of the State of Delaware, without regard to its conflict of laws rules. The state and federal courts located in Delaware have exclusive jurisdiction, and each party consents to venue there.

Before filing anything, please write to us. Most disputes are resolved faster by a conversation than by a filing.
