By creating an account, requesting a demonstration, or otherwise accessing or using the Services, you agree to be bound by these Terms and all policies incorporated by reference, including our Privacy Policy. If you do not agree to these Terms, you must immediately cease use of the Services.

Section 2

Description of Services

ERSO provides a business-to-business sales intelligence platform designed for HVAC sales professionals. The Services include: identification of commercial facilities using publicly available facility and permit data; enrichment of professional contact information associated with those facilities through integrations with third-party B2B data providers; organization and management of prospect lists; and export of prospect data in standard file formats.

ERSO reserves the right to modify, enhance, suspend, or discontinue any feature or aspect of the Services at any time, with or without notice. We will endeavor to provide advance notice of material changes to core functionality.

The Services are provided on a software-as-a-service basis and are intended to supplement, not replace, your own sales judgment and due diligence. ERSO does not guarantee the accuracy, completeness, or fitness for any particular purpose of facility data, contact data, or any other information delivered through the Services.

Section 3

Account Registration and Security

To access the Services, you must register for an account by providing accurate, current, and complete information as requested. You are responsible for maintaining the accuracy of your account information and for updating it promptly if it changes.

You are solely responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You must not share your credentials with any third party. You agree to notify ERSO immediately at privacy@ersoai.com if you become aware of any unauthorized access to or use of your account.

ERSO shall not be liable for any loss or damage arising from your failure to maintain the security of your account credentials. We reserve the right to suspend or terminate any account that we reasonably believe has been compromised or is being used in an unauthorized manner.

Section 4

Subscription Plans and Payment

4.1 Subscription and Fees

Access to the Services requires a paid subscription. Subscription plans, features, and pricing are described on our website and in your subscription agreement. ERSO reserves the right to change pricing with reasonable advance notice. Continued use of the Services following a price change constitutes acceptance of the new pricing.

4.2 Billing and Payment

By providing payment information, you authorize ERSO to charge the applicable fees to your designated payment method on a recurring basis in accordance with your selected plan. All fees are stated and charged in U.S. dollars. Payments are processed by a third-party payment processor and are subject to that processor's terms and policies.

4.3 Taxes

Fees are exclusive of all applicable taxes. You are responsible for all taxes, levies, or duties imposed by taxing authorities applicable to your purchase, excluding taxes based on ERSO's net income.

4.4 Refunds

Unless otherwise required by applicable law or expressly stated in your subscription agreement, all fees are non-refundable. If you cancel your subscription before the end of a billing period, you will retain access to the Services through the end of that period, and no partial refunds will be issued.

4.5 Late Payment

If payment is not received by the due date, ERSO reserves the right to suspend access to the Services until outstanding amounts are paid, and to assess late fees as permitted by applicable law.

Section 5

Acceptable Use Policy

  • Use the Services for any purpose that is unlawful, deceptive, fraudulent, or harmful to ERSO, other users, or third parties.
  • Transmit unsolicited bulk commercial email or engage in any form of spamming using data obtained through the Services, in violation of the CAN-SPAM Act, TCPA, or any other applicable law.
  • Use the Services to collect or process personal information for purposes other than B2B commercial sales outreach directed at business professionals acting in their professional capacities.

  • Use the Services in any manner that imposes an unreasonable or disproportionate burden on ERSO's infrastructure.
  • Remove, alter, or obscure any proprietary notices, branding, or labels displayed through the Services.

ERSO reserves the right to investigate suspected violations of this Acceptable Use Policy and to suspend or terminate access without prior notice where a violation is reasonably suspected. ERSO may also report suspected unlawful conduct to appropriate law enforcement authorities.

You may terminate your subscription at any time by providing written notice to ERSO at privacy@ersoai.com or by canceling through your account settings. Termination will be effective at the end of the then-current billing period. No refund will be issued for unused portions of a prepaid period.

11.3 Termination by ERSO

ERSO reserves the right to suspend or terminate your access to the Services, with or without notice, if: (a) you breach any provision of these Terms; (b) ERSO is required to do so by law or court order; (c) ERSO determines that continued provision of the Services to you creates legal or reputational risk; or (d) ERSO discontinues the Services in whole or in part. ERSO will endeavor to provide advance notice of non-breach terminations where reasonably practicable.

11.4 Effect of Termination

Upon termination, your right to access and use the Services shall immediately cease. ERSO will handle your data in accordance with the Privacy Policy and Data Retention Policy.

These Terms and any disputes arising out of or related to them or the Services shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflict of law principles.

12.2 Informal Resolution

12.3 Binding Arbitration

If informal resolution fails, any dispute, claim, or controversy arising out of or relating to these Terms or the Services that is not resolved informally shall be settled by binding arbitration administered by the American Arbitration Association ("AAA") under its Commercial Arbitration Rules.

12.4 Class Action Waiver

Notwithstanding the foregoing, either party may seek emergency injunctive or other equitable relief in any court of competent jurisdiction to prevent actual or threatened infringement of intellectual property rights or breach of confidentiality obligations.

Section 13

Modifications to Terms

ERSO reserves the right to modify these Terms at any time. When we make material changes, we will update the "Last Revised" date at the top of this page and provide notice through the Platform or by email to the address associated with your account.

Section 14

General Provisions

14.1 Entire Agreement

These Terms, together with the Privacy Policy, Data Retention Policy, Data Processing Agreement, and any applicable subscription or service agreement, constitute the entire agreement between you and ERSO with respect to the Services and supersede all prior or contemporaneous understandings, representations, and agreements.

14.2 Severability

You may not assign or transfer your rights or obligations under these Terms without ERSO's prior written consent. ERSO may assign these Terms, including in connection with a merger, acquisition, or sale of assets, without restriction.
