Terms of Service

Last updated: March 30, 2026

1. Acceptance of Terms

By accessing or using TwinPhone (twin-phone.com) and any related services (collectively, the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, you must not use the Service. We may update these Terms from time to time; material changes will be communicated via email or a prominent notice on the Service at least 30 days before taking effect. Continued use after the effective date constitutes acceptance.

2. Description of Service

TwinPhone provides browser-based voice calling to landlines and mobile phones worldwide. The Service may include outbound calling, virtual phone numbers, call recording, and team management features. Features may be added, modified, or removed at our discretion without liability.

3. Eligibility & Account Registration

You must be at least 18 years old (or the age of majority in your jurisdiction) to use the Service. By registering, you represent that all information you provide is accurate, current, and complete. You are solely responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You must notify us immediately of any unauthorized use. TwinPhone is not liable for any loss arising from unauthorized account access.

4. Billing & Credits

TwinPhone uses a pay-as-you-go credit system. Credits are purchased in advance and deducted per minute (rounded up) of call time at the rates published on twin-phone.com/rates at the time the call is placed. Credits do not expire. We reserve the right to change rates at any time; current rates are always displayed before you initiate a call. Virtual numbers are billed monthly and may be cancelled at any time. All prices are in US Dollars (USD) unless stated otherwise. You are responsible for any applicable taxes.

5. Refunds

Unused credits are refundable within 30 days of purchase upon request. Partially used top-ups and virtual number monthly fees for the current billing period are non-refundable. To request a refund, contact support@twin-phone.com. Refunds are processed within 10 business days to the original payment method. We reserve the right to deny refund requests that we reasonably believe to be fraudulent or abusive.

6. Acceptable Use

You may not use the Service for:

  • Automated, auto-dialed, or robocalling
  • Unsolicited bulk or commercial calls (spam)
  • Fraudulent, deceptive, or misleading activity
  • Harassing, threatening, or abusive communications
  • Impersonating any person or entity
  • Transmitting malware or interfering with the Service infrastructure
  • Any activity that violates applicable local, state, national, or international laws
  • Circumventing rate limits, security measures, or usage restrictions

We reserve the right to immediately suspend or terminate accounts that violate these terms, without prior notice and without refund, at our sole discretion. We may also report violations to law enforcement authorities where appropriate.

7. Intellectual Property

The Service, including its design, text, graphics, logos, software, and all underlying technology, is the property of TwinPhone or its licensors and is protected by intellectual property laws. You are granted a limited, non-exclusive, non-transferable, revocable license to use the Service for its intended purpose. You may not copy, modify, distribute, reverse-engineer, or create derivative works from any part of the Service without our prior written consent.

8. Service Availability & No Emergency Services

We strive for high availability but do not guarantee uninterrupted, timely, secure, or error-free service. Call quality depends on your internet connection, hardware, browser, and the destination telecom network — factors outside our control. We may perform scheduled or unscheduled maintenance at any time.

IMPORTANT: TwinPhone is NOT a replacement for traditional telephone service. TwinPhone does NOT support calls to emergency services (such as 911, 112, 999, or any local emergency numbers). You must maintain an alternative means of contacting emergency services at all times. TwinPhone shall have no liability for any inability to reach emergency services.

9. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND FREEDOM FROM COMPUTER VIRUSES OR OTHER HARMFUL CODE. TWINPHONE DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR THAT DEFECTS WILL BE CORRECTED. YOU USE THE SERVICE ENTIRELY AT YOUR OWN RISK.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL TWINPHONE, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AFFILIATES, SUPPLIERS, OR LICENSORS (COLLECTIVELY, "TWINPHONE PARTIES") BE LIABLE FOR ANY:

  • INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES
  • LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITIES
  • COST OF PROCUREMENT OF SUBSTITUTE SERVICES
  • DAMAGES ARISING FROM SERVICE INTERRUPTION, DATA LOSS, OR SECURITY BREACHES
  • DAMAGES ARISING FROM THE CONDUCT OF ANY THIRD PARTY ON THE SERVICE

ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SERVICE, REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, OR OTHERWISE), EVEN IF ANY TWINPHONE PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

THE TOTAL AGGREGATE LIABILITY OF THE TWINPHONE PARTIES FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE SHALL NOT EXCEED THE GREATER OF: (A) THE TOTAL AMOUNT YOU HAVE PAID TO TWINPHONE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) TEN US DOLLARS (USD $10.00).

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES OR WARRANTIES. IN SUCH JURISDICTIONS, OUR LIABILITY SHALL BE LIMITED TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW. NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, FRAUD, OR ANY LIABILITY THAT CANNOT BE EXCLUDED BY LAW.

11. Indemnification

You agree to indemnify, defend, and hold harmless the TwinPhone Parties from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees and court costs) arising from or related to: (a) your use or misuse of the Service, (b) your violation of these Terms or applicable law, (c) your violation of the rights of any third party, (d) any content or data you transmit through the Service, or (e) any fraudulent or illegal activity conducted through your account. This indemnification obligation survives termination of your account and these Terms.

12. Termination

You may close your account at any time through your account settings or by contacting us. We may suspend or terminate your account at any time, with or without cause, with or without notice, at our sole discretion. Upon termination: any remaining credits are non-refundable (except as required by applicable law), your right to use the Service ceases immediately, and we may delete your account data in accordance with our Privacy Policy. Sections 9 through 17 of these Terms survive termination.

13. Force Majeure

TwinPhone shall not be liable for any failure or delay in performance resulting from causes beyond our reasonable control, including but not limited to: natural disasters, acts of government, war, terrorism, pandemics, labor disputes, internet or telecom infrastructure failures, power outages, cyberattacks, or actions of third-party service providers.

14. Governing Law & Dispute Resolution

These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of laws principles. Any dispute, claim, or controversy arising out of or related to these Terms or the Service shall be resolved through binding individual arbitration, administered in accordance with the rules of a recognized arbitration body, conducted in English.

CLASS ACTION WAIVER: YOU AND TWINPHONE AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS AND MAY NOT PRESIDE OVER ANY FORM OF CLASS OR REPRESENTATIVE PROCEEDING.

Nothing in this section limits your right to bring claims before your local consumer protection agency or small claims court (if eligible), or any mandatory rights that cannot be waived under the consumer protection laws of your jurisdiction. For users in the European Union, you may also use the European Online Dispute Resolution platform (ec.europa.eu/odr).

15. Severability

If any provision of these Terms is found to be unenforceable or invalid by a court of competent jurisdiction, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.

16. Entire Agreement

These Terms, together with the Privacy Policy and Cookie Policy, constitute the entire agreement between you and TwinPhone regarding the Service and supersede all prior agreements, understandings, and representations. No waiver of any provision shall be deemed a continuing waiver or a waiver of any other provision.
