Welcome to FosterFlow. These Terms of Service (the “Terms”) govern access to and use of FosterFlow’s websites, applications, APIs, software, email-sending services, automation features, audience tools, templates, content assets, integrations, and related services (collectively, the “Services”).

These Terms are a binding agreement between Foster Flow Limited (registered in Hong Kong) and the customer entity or person that registers for, accesses, or uses the Services (“Customer”). By accessing or using the Services, Customer agrees to these Terms. If the individual accepting these Terms is doing so on behalf of an organization, that individual represents that they have authority to bind the organization.

• 3.2 Service Changes: FosterFlow may update or modify features from time to time. We will use commercially reasonable efforts to avoid materially reducing core subscribed functionality during a paid term, except for security, legal, or provider-compliance reasons.

• 7.3 Taxes: Customer is responsible for all sales, use, or value-added taxes (VAT), except taxes based on FosterFlow’s net income.

• 7.4 Late Payment: Failure to pay amounts due may result in the suspension of access to the Services.

8. Confidentiality

• 8.1 Obligations: Each party agrees to protect the other’s non-public “Confidential Information” (including business plans, pricing, and Customer Data) using at least a reasonable degree of care. Disclosure is only permitted to personnel or advisors who “need to know” and are bound by confidentiality terms.

9. Security

• FosterFlow will maintain commercially reasonable administrative, technical, and organizational safeguards designed to protect Customer Data. However, no system is perfectly secure; Customer is responsible for securing its own credentials and connected systems.

10. Suspension and Termination

• 10.1 Suspension: FosterFlow may throttle, suspend, or terminate access if we reasonably believe Customer has violated the Agreement, created security risks, or harmed provider deliverability.

• 10.2 Immediate Action: Immediate suspension without notice may occur in cases of malware, fraud, or urgent security threats.

12. Warranties and Disclaimers

13. Limitation of Liability

• 13.1 Excluded Damages: To the maximum extent permitted by law, neither party will be liable for indirect, incidental, or consequential damages (loss of profits, data, or goodwill).

• 13.2 Aggregate Cap: Each party’s total liability shall not exceed the amounts paid or payable by Customer to FosterFlow during the twelve (12) months preceding the claim.

14. Indemnification

15. Governing Law and Venue

• These Terms are governed by the laws of Hong Kong, without regard to conflict-of-law rules. Any disputes arising out of this Agreement shall be subject to the exclusive jurisdiction of the courts located in Hong Kong.
