Clear terms, no surprises.
These Terms govern your use of all Ringflow services. We've written them to be as readable as possible — please take the time to read them fully before using the platform.
Last updated: May 9, 2026
1. Acceptance of Terms
By accessing or using any Ringflow service — including ringflow.com, the Ringflow dashboard, our REST API, mobile apps, or any related software (collectively, the "Services") — you agree to be bound by these Terms and Conditions ("Terms"). If you are accepting these Terms on behalf of a company or other legal entity, you represent that you have the authority to bind that entity.
If you do not agree to these Terms, you may not access or use the Services. Ringflow Inc. ("Ringflow", "we", "our") reserves the right to update these Terms at any time. Continued use of the Services after changes are posted constitutes acceptance of the revised Terms.
2. License to Use
Ringflow grants you a limited, non-exclusive, non-transferable, revocable licence to access and use the Services solely for your internal business communications purposes, in accordance with these Terms and any applicable Ringflow documentation.
You may not:
- Sublicense, resell, or commercially exploit the Services without Ringflow's prior written consent.
- Reverse-engineer, decompile, or disassemble any part of the platform or API.
- Use the Services to build a competing product or service.
- Remove or obscure any proprietary notices, branding, or labels on the Services.
- Use automated means to access the Services in ways that exceed documented API rate limits or that circumvent security controls.
Any use of the Services outside the scope of this licence requires Ringflow's express prior written permission.
3. Subscription & Service Plans
Ringflow offers several subscription tiers — Sandbox, Starter, Business, and Enterprise — each with different feature sets, usage limits, and pricing. Details of each plan are published at ringflow.com/pricing and may be updated from time to time.
Your subscription begins on the date you activate your paid plan. Ringflow may modify, add, or discontinue features or services within a plan with 30 days' prior written notice for material changes. Minor updates (bug fixes, UI improvements, minor capability additions) may be deployed without notice.
Enterprise customers operate under a separate Order Form and Master Service Agreement, the terms of which take precedence over these Terms where they conflict.
4. Customer Responsibilities
Legal Compliance
You are solely responsible for ensuring your use of the Services complies with all applicable laws and regulations, including telecommunications law, data protection law (GDPR, CCPA), anti-spam regulations (TCPA, CAN-SPAM), and export control laws. You must not use the Services to transmit unlawful, harassing, defamatory, or fraudulent communications.
Account Security
You are responsible for maintaining the confidentiality of your account credentials. You must immediately notify Ringflow at security@ringflow.com if you suspect unauthorised access to your account. Ringflow is not liable for losses caused by unauthorised access resulting from your failure to protect your credentials.
End-User Management
If you provide Services to your own end-users (e.g., as part of a UCaaS or reseller arrangement), you are responsible for ensuring those end-users comply with these Terms and Ringflow's Acceptable Use Policy. You must have a lawful basis for any personal data you transmit through the platform.
Acceptable Use
You must not use the Services for robocalling, autodial campaigns, SMS spam, phishing, call spoofing, toll fraud, or any activity that violates Ringflow's Acceptable Use Policy (published at ringflow.com/acceptable-use). Ringflow reserves the right to suspend or terminate Services immediately for violations.
Emergency Services
Ringflow's cloud phone services are not a substitute for traditional telephone service and do not support enhanced emergency services (E911) in all jurisdictions. You must ensure that any users who may need to reach emergency services have access to an alternative means of doing so. By using the Services, you acknowledge this limitation.
5. Charges & Payment
Monthly Billing
Subscription fees are billed monthly in advance on the anniversary of your activation date. Usage-based charges (call minutes, SMS segments, AI session minutes) are billed monthly in arrears. All fees are in US dollars unless otherwise agreed in writing.
Payment Methods
Ringflow accepts major credit cards and ACH bank transfers for Business and Enterprise plans. Payments are processed by our PCI-DSS-certified payment processor. By providing payment details, you authorise Ringflow to charge your payment method for all fees incurred under your account.
Late Payment
Invoices not paid within 15 days of the due date will incur a 1.5% monthly late fee (or the maximum permitted by law, whichever is lower). Ringflow reserves the right to suspend Services for accounts overdue by more than 30 days. Services will be reinstated within 24 hours of payment clearing.
Taxes
All fees are exclusive of applicable taxes. You are responsible for all sales, use, value-added, withholding, and similar taxes imposed by any jurisdiction on the Services, except for taxes based on Ringflow's net income.
Disputes
Any billing disputes must be raised in writing within 30 days of the invoice date by emailing billing@ringflow.com. Disputes raised after this period will not be eligible for credit.
Free Trial
New accounts receive a Sandbox environment at no charge. If you activate a paid plan following a trial, your card will be charged on the first day of the billing cycle. Ringflow may discontinue or modify free trial terms at any time.
Cancellation & Refunds
You may cancel your subscription at any time from the dashboard. Cancellation takes effect at the end of the current billing period. Ringflow does not provide pro-rated refunds for unused portions of a subscription month, except where required by applicable law.
6. Intellectual Property
All rights, title, and interest in and to the Services — including the platform software, API, documentation, trademarks, logos, and all underlying technology — are and remain the exclusive property of Ringflow Inc. and its licensors. These Terms do not transfer any intellectual property rights to you.
Your Content
You retain all rights to the data, call recordings, messages, and other content you upload to or generate through the Services ("Customer Content"). You grant Ringflow a limited licence to host, process, and transmit Customer Content solely as necessary to provide the Services.
Feedback
If you provide suggestions, ideas, or feedback about the Services ("Feedback"), you grant Ringflow a perpetual, irrevocable, worldwide, royalty-free licence to use that Feedback for any purpose, including incorporation into the Services, without compensation or attribution to you.
7. Confidentiality
Each party agrees to keep confidential all non-public information disclosed by the other party that is designated as confidential or that reasonably should be understood to be confidential given the nature of the information ("Confidential Information").
Neither party will disclose Confidential Information to any third party without the other party's prior written consent, except to employees, contractors, or advisors who have a need to know and are bound by confidentiality obligations at least as protective as those in these Terms.
These obligations do not apply to information that: (a) is or becomes publicly available through no breach of these Terms; (b) was already known to the receiving party without restriction; (c) is independently developed without reference to the Confidential Information; or (d) is required to be disclosed by law or court order, provided the receiving party gives prompt notice where legally permitted.
8. Disclaimer of Warranties
THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, RINGFLOW EXPRESSLY DISCLAIMS ALL WARRANTIES — EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE — INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
Ringflow does not warrant that the Services will be uninterrupted, error-free, or completely secure. Telecommunications services are subject to factors outside Ringflow's control, including carrier outages, regulatory changes, and force majeure events. Ringflow's uptime SLA (published at ringflow.com/sla) sets out our commitments and your sole remedies for service unavailability.
9. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, RINGFLOW'S TOTAL CUMULATIVE LIABILITY TO YOU FOR ANY CLAIMS ARISING UNDER OR RELATED TO THESE TERMS OR THE SERVICES — WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), OR OTHERWISE — SHALL NOT EXCEED THE GREATER OF: (A) THE TOTAL FEES PAID BY YOU TO RINGFLOW IN THE THREE (3) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM; OR (B) ONE HUNDRED US DOLLARS (USD $100).
IN NO EVENT SHALL RINGFLOW BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES — INCLUDING LOSS OF PROFITS, LOSS OF DATA, BUSINESS INTERRUPTION, OR COST OF SUBSTITUTE SERVICES — EVEN IF RINGFLOW HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of liability for certain damages. In such jurisdictions, our liability will be limited to the greatest extent permitted by law.
10. Indemnification
You agree to defend, indemnify, and hold harmless Ringflow Inc. and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to:
- Your use of the Services in violation of these Terms or applicable law.
- Your Customer Content or the content of calls and messages sent through your account.
- Your violation of any third-party right, including intellectual property or privacy rights.
- Any claims by your end-users arising from your use of the Services.
Ringflow will promptly notify you of any claim subject to indemnification and will cooperate reasonably with your defence. You may not settle any such claim in a way that imposes obligations or liability on Ringflow without Ringflow's prior written consent.
11. Termination
Termination by You
You may terminate your account at any time by cancelling your subscription from the dashboard or by contacting support@ringflow.com. Termination takes effect at the end of the current billing period. You remain responsible for all fees incurred through the termination date.
Termination by Ringflow
Ringflow may suspend or terminate your account immediately, without notice, if:
- You materially breach these Terms and fail to cure the breach within 10 days of written notice (where cure is possible).
- You breach the Acceptable Use Policy.
- We are required to do so by law or a regulatory authority.
- Continued provision of Services poses a security or legal risk to Ringflow or other customers.
Effect of Termination
Upon termination, your licence to use the Services ends immediately. You may export your data for 30 days following termination using the self-service export tools in the dashboard. After 30 days, your data will be deleted in accordance with our data retention policy. Sections 6, 7, 8, 9, 10, 13, and 14 survive termination.
12. Force Majeure
Neither party shall be liable to the other for any delay or failure to perform its obligations under these Terms if such delay or failure results from causes beyond that party's reasonable control, including acts of God, war, terrorism, civil disturbance, government action, labour disputes, internet or carrier outages, natural disasters, or pandemics.
The party affected by a force majeure event must promptly notify the other party and use commercially reasonable efforts to resume performance. If a force majeure event prevents performance for more than 60 consecutive days, either party may terminate the affected Services with written notice, without liability.
13. Governing Law & Disputes
These Terms shall be governed by and construed in accordance with the laws of the State of New York, United States, without regard to its conflict-of-law provisions.
Dispute Resolution
The parties agree to first attempt to resolve any dispute informally by contacting legal@ringflow.com. If the dispute is not resolved within 30 days, it shall be submitted to binding arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules. The arbitration shall take place in New York, NY, and shall be conducted in English.
Class Action Waiver
You agree that any arbitration or legal proceeding shall be conducted solely on an individual basis. You waive any right to participate in a class action lawsuit or class-wide arbitration.
Exception
Notwithstanding the above, either party may seek injunctive or other equitable relief in any court of competent jurisdiction to prevent irreparable harm, including in cases involving intellectual property infringement.
14. General Provisions
Entire Agreement
These Terms, together with the Privacy Policy, Acceptable Use Policy, and any Order Forms or Master Service Agreements, constitute the entire agreement between you and Ringflow regarding the Services and supersede all prior agreements and understandings.
Severability
If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force and effect.
Waiver
Ringflow's failure to enforce any right or provision of these Terms shall not constitute a waiver of that right or provision.
Assignment
You may not assign your rights or obligations under these Terms without Ringflow's prior written consent. Ringflow may assign these Terms in connection with a merger, acquisition, or sale of assets.
Notices
Legal notices to Ringflow should be sent by email to legal@ringflow.com and by post to: Ringflow Inc., 1 World Trade Center, New York, NY 10007, United States. Ringflow will send notices to the email address associated with your account.
Updates to These Terms
We may revise these Terms from time to time. When we make material changes, we will notify you by email and post a notice on the platform at least 30 days before the changes take effect. Your continued use of the Services after the effective date constitutes acceptance of the revised Terms.
Our Commitment
Fair terms. Plain language.
We write our terms to be understood, not to trap you. Month-to-month flexibility, clear cancellation policies, and no auto-renewal surprises — because a vendor relationship should feel like a partnership, not a legal maze.
