Terms of Service

Effective Date: April 13, 2026

These Terms of Service ("Terms") govern your use of the FSEN platform ("Service") provided by Fsen ("FSEN," "we," "us," or "our"). By using the Service, you agree to these Terms. If you do not agree, do not use the Service.

Please read carefully.

FSEN is a notification platform. FSEN is not a dispatcher, not a monitoring service, not an emergency response provider, and not a guarantor that any message will be delivered, received, read, or acted upon. You — the customer — are the dispatcher and are responsible for how your organization responds to any event routed through the Service. Sections 1 through 4 describe exactly what the Service is and what it is not.

1. What the Service Is

FSEN is a software platform that routes inbound phone calls and SMS messages received on phone numbers you provision through FSEN, and sends outbound SMS and voice notifications to phone numbers you designate, according to rules you configure.

The Service gives you tools to:

  • Receive inbound calls and texts on a phone number provisioned through FSEN
  • Configure lists of workers, vendors, or other recipients you want notified
  • Automatically forward inbound messages to those recipients via SMS
  • Record events, notes, timestamps, and attachments for your own reference
  • Manage subscriptions, users, schedules, and settings through a web portal

The Service is a communication tool that you operate. You decide who is notified, in what order, under what conditions, and what happens next. FSEN does not make any of those decisions on your behalf and does not monitor whether they are made at all.

2. What the Service Is Not

To avoid any ambiguity:

  • FSEN is not a dispatcher. We do not operate a dispatch center. We do not employ personnel who triage calls, assess emergencies, prioritize incidents, or make operational decisions on your behalf. All dispatch decisions — including whether, when, how, and to whom to respond — are made by you and your personnel.
  • FSEN is not a monitoring or emergency response service. We do not monitor your account, your incidents, your response times, or whether anyone at your organization is available or acting. We do not dispatch police, fire, medical, or any other emergency responders.
  • FSEN is not a 911 service or telecommunications carrier. The Service is not a substitute for 911, E911, or any public safety answering point. For life-threatening emergencies, always call 911 directly.
  • FSEN is not a guarantor of delivery, response, or outcomes. We make no representation that any SMS message, voice call, or notification will be delivered, received, read, acknowledged, or acted upon within any timeframe, or at all. SMS and voice depend on carriers, networks, device state, and recipient behavior that we do not control.
  • FSEN is not liable for outcomes. Any property damage, personal injury, financial loss, regulatory exposure, missed response, delayed response, or other consequence arising from events you handle through the Service is your responsibility, not ours. See Sections 12 and 13.

3. Customer Responsibility

You are the dispatcher. You are operationally and legally responsible for:

  • Defining who receives notifications and in what order
  • Ensuring that designated recipients are available, competent, and equipped to respond
  • Verifying that notifications are actually received and acted upon
  • Monitoring your own response times and escalation paths
  • Communicating with clients, tenants, and other stakeholders about your response expectations and limitations
  • Maintaining independent procedures for situations where the Service is unavailable, delayed, or fails to deliver a message
  • Complying with all laws, regulations, licensing, insurance, and safety requirements that apply to your business

The Service is a tool you use to run your operations. It is not a replacement for operational judgment, trained personnel, or a backup communication plan.

4. Acknowledgement of Limitations

By using the Service, you acknowledge and agree that:

  • SMS and voice communications are inherently unreliable and can fail silently
  • Delivery timing can be affected by carrier congestion, network outages, device conditions, and factors outside FSEN's control
  • You have evaluated whether the Service meets your operational needs and have accepted the limitations described in these Terms
  • You will not rely on the Service as your sole means of emergency communication or your sole safeguard against the consequences of a missed or delayed response

5. Eligibility and Accounts

The Service is intended for commercial and professional use by individuals 18 years or older. By using the Service, you represent that you are at least 18 years old and have the authority to bind the organization you represent.

You are responsible for maintaining the security of your account credentials and registered phone numbers. Notify us immediately at support@fsen.tech if you suspect unauthorized access.

6. SMS and Voice Consent

By providing your phone number and using the Service, you expressly consent to receive SMS, MMS, and voice communications related to the notifications the Service is configured to send, service operations, account alerts, and billing.

  • Message frequency varies based on your configuration and inbound activity
  • Message and data rates may apply depending on your carrier plan
  • Reply STOP to opt out of optional messages at any time
  • Reply HELP for assistance or contact support@fsen.tech

Essential service messages (security alerts, billing notices, terms updates) cannot be opted out of while you maintain an active account. Opting out of SMS will prevent the Service from delivering notifications to you and may make the Service unusable.

7. Acceptable Use

You agree not to:

  • Use the Service for any unlawful purpose or in violation of any applicable law
  • Submit false reports or abuse the notification system
  • Attempt to gain unauthorized access to any part of the Service
  • Interfere with or disrupt the Service or its infrastructure
  • Send spam, unsolicited messages, or harassing content through the Service
  • Share account credentials or allow unauthorized individuals to use your account
  • Reverse engineer, decompile, or attempt to extract the source code of the Service
  • Represent to your own clients or the public that FSEN is a dispatcher, monitoring provider, emergency service, or guarantor of response

We reserve the right to suspend or terminate accounts that violate these Terms.

8. Group Communications

The Service may create group SMS conversations to fan notifications out to multiple recipients. By participating, you understand and agree that:

  • All messages, photos, and attachments are visible to every participant in the group
  • Participant names and phone numbers are visible to other participants
  • Conversations are recorded and archived for the account holder's reference and audit
  • You should only share information necessary for the notification you are sending

9. Fees and Payment

Service fees are as described on our website or in your subscription agreement. Fees are billed in advance on a monthly or annual basis and are non-refundable except as required by law. We reserve the right to change pricing with 30 days notice.

Standard carrier charges for SMS and data usage are your responsibility. FSEN is not responsible for carrier fees.

10. Intellectual Property

The Service, including all software, design, text, and content created by FSEN, is our property or the property of our licensors and is protected by intellectual property laws. You may not copy, modify, distribute, or create derivative works from our Service without written permission.

Content you submit through the Service (messages, photos, documents) remains your property, but you grant us a license to use, store, and process it as necessary to provide and improve the Service.

11. Service Availability

We strive to provide reliable service but do not guarantee uninterrupted or error-free operation. The Service depends on third-party infrastructure including SMS carriers, voice carriers, cloud providers, and telecommunications networks that we do not control.

  • SMS and voice delivery are subject to carrier availability and network conditions
  • Standard SMS is not end-to-end encrypted (a limitation of SMS technology)
  • We may perform scheduled maintenance with reasonable advance notice
  • Force majeure events (natural disasters, carrier outages, etc.) may affect service
  • The Service may be unavailable, delayed, or partially functional at any time and for any duration without notice

12. Disclaimer of Warranties

The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. FSEN does not warrant that the Service will be uninterrupted, secure, or error-free, that any message or notification will be delivered, received, read, or acted upon, that delivery will occur within any specific timeframe, or that use of the Service will produce any particular operational outcome. You assume all risk associated with use of the Service as part of your operations.

13. Limitation of Liability

To the maximum extent permitted by law, FSEN and its officers, directors, employees, affiliates, and agents shall not be liable for any direct, indirect, incidental, special, consequential, exemplary, or punitive damages arising from or related to your use of the Service. This includes, without limitation, damages arising from: (a) any failure, delay, non-delivery, or misdelivery of any notification, SMS, or voice communication; (b) any missed, delayed, or inadequate response by you, your personnel, your vendors, or any third party; (c) any property damage, personal injury, loss of life, business interruption, lost profits, regulatory exposure, reputational harm, or other consequences of events you handle through the Service; and (d) any decision made or not made by any recipient of a notification.

FSEN is a notification platform. FSEN is not the operator of your business and is not responsible for outcomes. In jurisdictions where the above exclusions are not permitted, FSEN's total aggregate liability for any and all claims arising from or related to the Service shall not exceed the fees you paid to FSEN in the twelve (12) months preceding the event giving rise to the claim.

14. Indemnification

You agree to indemnify, defend, and hold harmless FSEN and its officers, directors, employees, affiliates, and agents from and against any claims, damages, losses, liabilities, judgments, settlements, and expenses (including reasonable attorneys' fees) arising from or related to: (a) your use of the Service; (b) your violation of these Terms; (c) your infringement of any third-party rights; (d) any event, incident, response, or non-response that you, your personnel, or your vendors handle through the Service; or (e) any representation you make to your clients, tenants, or the public about FSEN's role or capabilities that is inconsistent with Sections 1 through 4.

15. Termination

Either party may terminate the Service at any time. We may suspend or terminate your access immediately if you violate these Terms or engage in conduct that we determine is harmful to the Service or other users.

Upon termination, your right to use the Service ceases. We will retain data as described in our Privacy Policy, including records required for legal compliance.

16. Governing Law and Disputes

These Terms are governed by the laws of the Commonwealth of Massachusetts without regard to conflict of law principles. Any disputes arising from these Terms or the Service shall be resolved in the state or federal courts located in Suffolk County, Massachusetts.

17. Changes to These Terms

We may update these Terms from time to time. Material changes will be communicated via email, SMS, or website notice at least 30 days before taking effect. Continued use of the Service after changes take effect constitutes acceptance of the updated Terms.

18. Privacy

Your use of the Service is also governed by our Privacy Policy, which describes how we collect, use, and protect your information. By using the Service, you acknowledge that you have read and understood the Privacy Policy.
