This Phone Number Policy (the "Policy") governs your provisioning and use of U.S. telephone numbers ("Numbers") through Simba Voice, a service provided by Speechify, Inc. ("Speechify," "we," "us"). It supplements — and is incorporated into — the Speechify Terms of Service (the "Terms") and the Speechify Privacy Policy. Capitalized terms not defined here have the meanings given in the Terms. If anything in this Policy conflicts with the Terms, this Policy controls only with respect to Numbers and the calls and messages associated with them.

This Policy applies to business customers of Speechify ("Customers," "you") who use Simba Voice to operate voice agents — whether for their own use cases, with their own customers, or as part of a service or product they make available to others. The individuals or businesses that receive calls or messages from your voice agent are referred to as "Recipients." You — not Speechify — are the party that decides who to contact, what to say, and on what legal basis. Speechify provides the platform and the underlying telecom infrastructure.

Plain-English summary

This is not a substitute for the full text below, but it captures the gist:

A Number we issue you is licensed, not sold. You don't own it.
You — not Speechify — are responsible for what your voice agent says or texts, who it contacts, and whether you have permission to contact them.
You must follow U.S. telecom and consumer-protection laws. That includes the TCPA, robocall and Do-Not-Call rules, STIR/SHAKEN, A2P 10DLC, CTIA messaging guidelines, two-party recording-consent laws, and applicable state laws.
Twilio is our underlying carrier. Twilio's Acceptable Use Policy and Messaging Policy apply to your traffic. If Twilio suspends your traffic, your Number stops working.
We can monitor traffic for abuse, suspend a Number without notice if it endangers our platform or our carriers, and reclaim Numbers that are unused, abused, or unpaid.
You agree to indemnify Speechify for any claims arising from your use of a Number.

Your Acknowledgments

By requesting or using a Number, you represent and agree that:

You will obtain consent. You will obtain and retain any consent required by law before any call is placed or any message is sent, including prior express written consent for AI-voice or marketing calls under the TCPA where applicable.
You will follow opt-outs. You will honor STOP, do-not-call, and equivalent opt-out requests promptly and across all channels.
You will scrub against do-not-call lists. You will scrub your outbound lists against the National Do-Not-Call Registry and applicable state DNC lists before each campaign.
You will not spoof or misrepresent. You will not falsify caller ID, manipulate STIR/SHAKEN attestation, or impersonate a person or entity without their written authorization.
You will register where required. Where you send SMS/MMS to U.S. mobile numbers, you will register your brand and campaigns under A2P 10DLC and stay within registered limits.
You will disclose recordings and AI agents. Where calls placed or received through your Number are recorded, transcribed, or processed by an AI voice agent, you will obtain consent and provide disclosures required by all applicable wiretap and AI-disclosure laws (including in two-party-consent states).
You will not use Numbers for unlawful, fraudulent, harassing, or sanctioned purposes.
You accept Twilio's pass-through rules. You will comply with Twilio's Acceptable Use Policy and Messaging Policy and any U.S. carrier or regulator requirement applied to your traffic.
You accept monitoring. You agree we and our carriers may log, monitor, and analyze your traffic to detect abuse and enforce this Policy.
You will indemnify us. You will indemnify Speechify and our carriers (including Twilio) for claims, fines, and pass-through penalties arising from your use of a Number, as set out below.

1. Eligibility and Account Responsibility

You may request a Number only if you (a) have an active Simba Voice account in good standing, (b) are a business or other entity, or an adult acting in a business capacity, located in the United States, and (c) are not a person or entity blocked under U.S. economic sanctions. You are responsible for all activity conducted through any Number associated with your account, including activity by your employees, contractors, end users, and any voice agent you configure or deploy.

If you provision or use a Number to provide services to your own customers or end users (a "Sub-Customer"), you represent that you have authority to bind that Sub-Customer to obligations equivalent to this Policy and that you will, in fact, do so. Speechify may, at its discretion, require additional information about your Sub-Customers — including for KYC, A2P 10DLC, or carrier-registration purposes — and may require that the Sub-Customer be registered as the "End User" of the Number for those purposes.

2. Number Ownership, Porting, and Reclamation

Numbers are licensed to you, not sold. Speechify (or our underlying carrier, Twilio) is the registered subscriber of record. You receive a non-exclusive, non-transferable, revocable right to use the Number while this Policy is in effect and your account is in good standing.

We may, with reasonable notice where practicable, change or reclaim a Number if (a) regulators or carriers require it, (b) the Number is unused for an extended period, (c) your account is delinquent, or (d) we reasonably suspect the Number is being used in violation of this Policy. If you ask to port a Number out to another provider, we will cooperate with reasonable port-out requests, subject to verification of your authority and payment of any then-current fees, but we cannot guarantee a successful port if the receiving carrier or local rules prevent it.

3. Acceptable Use

In addition to the prohibitions in Section 4 of the Terms, you must not use a Number — or permit it to be used — to:

Place or send communications without required consent. You must obtain — beforea call is placed or a message is sent — any consent required by law and must retain documentation of that consent for as long as required to defend a claim. This includes, where applicable, prior express consent and prior express written consent under the U.S. Telephone Consumer Protection Act ("TCPA"). Voice agents that use AI-generated, synthetic, or prerecorded voices are treated as "artificial or prerecorded voice" calls under the TCPA(consistent with the U.S. Federal Communications Commission's February 2024 declaratory ruling) and require prior express written consent for marketing or non-emergency calls to wireless and residential numbers, plus the disclosures required by 47 C.F.R. § 64.1200 (including identifying the caller, stating the purpose of the call, and providing an automated opt-out mechanism). You must also comply with any state-level AI-call disclosure laws that apply to your traffic.
Ignore opt-outs.You must honor any "STOP," "unsubscribe," "remove me," "do not call," or equivalent request — across any channel — promptly, and in any event no later than required by law (for SMS, generally the immediately following message; for telemarketing calls, no later than the timeframes set in the Telemarketing Sales Rule and the TCPA). You must maintain an internal opt-out list and suppress further outreach to anyone who has opted out, regardless of channel.
Call or message numbers on a Do-Not-Call registry (federal or state) without an applicable exemption. You must scrub your contact list against the National Do-Not-Call Registry and any applicable state DNC lists before each outbound campaign and again at the intervals required by law, and you must contact recipients only at times of day permitted by federal and state law.
Spoof, manipulate, or misrepresent caller ID or sender information, falsify SHAKEN attestation, or attempt to defeat call-authentication standards. You must use only Numbers we have assigned to you (or that you have legitimately ported in) as the calling or sending identity, and you must keep your registered caller-name (CNAM) and KYC information accurate and up to date.
Send SMS or MMS in violation of A2P 10DLC, CTIA Messaging Principles and Best Practices, carrier rules, or applicable U.S. messaging regulations.Before sending application-to-person traffic to U.S. mobile numbers, you must register your brand and each messaging campaign with The Campaign Registry (or any successor), maintain that registration in good standing, accurately classify your use case and content, and stay within the throughput and content limits of your registered campaign. You must not send SHAFT content (sex, hate, alcohol, firearms, tobacco) outside age-gated and lawfully permitted channels, and you must include the sender identity and the "Reply STOP to unsubscribe / HELP for help" instructions required by CTIA and carrier guidelines. We may register on your behalf where Twilio's ISV/reseller framework allows; in all other cases, registration is your responsibility.
Engage in fraud, scams, or deceptive practices, including phishing, smishing, vishing, payment fraud, fake-debt collection, fake-charity solicitation, romance scams, "wrong number" lures, or any communication intended to deceive the Recipient.
Impersonate any person or entity— including any government agency, financial institution, healthcare provider, or Speechify — without their written authorization, or use a voice clone that imitates a real person without that person's documented consent.
Threaten, harass, defame, or stalk any person, transmit unlawful content (including content depicting child sexual abuse, terrorism, or non-consensual intimate imagery), or coordinate violence, voter intimidation, voter suppression, or election interference.
Operate in regulated industries without required licensure or authorization. This includes financial services, lending, debt collection, insurance, healthcare, legal services, controlled substances, gambling, and political fundraising. You are responsible for any industry-specific obligations that apply to your communications (for example, HIPAA, FDCPA, GLBA, TCPA healthcare exemption rules, and state equivalents).
Generate artificial traffic, traffic-pumping, or revenue-share fraud (including IRSF), or send communications whose primary purpose is to inflate traffic, test high-volume routes, or extract carrier payouts.
Probe, attack, or interfere with telephony infrastructure, including denial-of-service, brute-forcing voicemail, war-dialing, or scanning carrier networks.
Resell, sublicense, or make Numbers available to third parties as a stand-alone telecom service, or operate Numbers in a way that effectively makes Speechify a downstream telecommunications reseller, without our prior written consent. This does not prohibit you from using Simba Voice to provide voice-agent services to your own Sub-Customers in the ordinary course, provided you bind those Sub-Customers as required by Section 1.

The list above is not exhaustive. Any conduct that violates applicable law, the Terms, Twilio's policies, or carrier rules is prohibited.

4. Recording, Transcription, and Voicemail

Calls placed or received through a Number are processed by Speechify's platform, which by design captures audio in real time and may generate recordings, transcripts, summaries, and voicemail. Even though you — not Speechify — decide which calls are placed, U.S. wiretap and recording-consent laws apply to whoever records or causes a call to be recorded. Because your use of Simba Voice causes that recording to occur, you are responsible for compliance and for the disclosures Recipients are entitled to receive. Specifically, you must:

Comply with all applicable federal and state wiretap, eavesdropping, and recording-consent laws — including the two-party (all-party) consent rulesin California (CIPA), Florida (Fla. Stat. § 934, where Speechify is headquartered), Illinois, Massachusetts, Pennsylvania, Washington, Maryland, Montana, Nevada, New Hampshire, and any other state that requires all-party consent. Where any party to the call is in such a state, you must obtain documented consent from every party before recording.
Disclose at the start of any recorded call that the call may be recorded, transcribed, or processed by an AI system, in clear and conspicuous language.
Provide a meaningful method for callers to opt out of recording or AI processing where the law requires it, or to reach a human if the caller requests one.
Apply appropriate retention limits and deletion procedures to recordings, transcripts, voicemail, and any associated personal data.

5. Twilio and Carrier Pass-Through Obligations

Numbers are provisioned through Twilio, Inc. ("Twilio") or another underlying U.S. carrier we may use from time to time. By using a Number, you agree that the following terms apply to your traffic and bind you directly:

Twilio's Acceptable Use Policy;
Twilio's Messaging Policy;
The CTIA Messaging Principles and Best Practices and the Mobile Marketing Association Consumer Best Practices, where applicable; and
Any traffic, throughput, registration, KYC, or attestation requirement imposed by a U.S. carrier, the FCC, or any other applicable regulator or numbering authority.

If Twilio or a downstream carrier suspends, throttles, blocks, or revokes a Number — or imposes fees, fines, or pass-through penalties because of your traffic — you are responsible for those consequences and any related costs.

6. Geographic Scope

Simba Voice Numbers are issued for use within the United States. You may not request, port, or use a Number from outside the United States, and you may not use a Number to place calls or send messages to recipients outside the United States, except as we may expressly permit in writing. You are responsible for compliance with U.S. economic sanctions and export controls, including those administered by the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC), and you will not use a Number to communicate with sanctioned parties.

7. Privacy, Monitoring, and Data Use

This Section 7 governs personal data that is collected, generated, or processed because a Simba Voice Number is provisioned or used. It supplements — and, where it directly addresses voice and messaging data, controls over — the more general Speechify Privacy Policy, which continues to govern personal data we collect through your Speechify account, the website, and the rest of our products.

What data is generated

When a Simba Voice Number is used, Speechify and our underlying carriers (including Twilio) may collect, generate, and process:

Phone numbers belonging to you, your personnel, your Sub-Customers, and your Recipients;
Call audio, including any portion of a Recipient's voice captured during a call;
Recordings, transcripts, and AI-generated summaries of calls;
Voicemail messages and their transcripts;
The content and metadata of SMS and MMS messages sent or received through the Number;
Call detail records, signaling data, and routing information, including time, duration, originating and terminating numbers, and delivery status; and
Information used to register your brand or campaigns with carriers, aggregators, or numbering authorities (for example, for A2P 10DLC).

How we use it

We use this information to provide and operate Simba Voice; to deliver calls and messages to and from your Number; to power voice-agent features such as transcription, intent detection, summarization, and follow-up; to maintain quality, security, and reliability; to detect and prevent fraud, abuse, and violations of this Policy or applicable law; to comply with lawful requests from regulators and carriers; to bill you and our carriers; and for the other purposes described in the Speechify Privacy Policy that are consistent with this Policy.

Controller / processor allocation

When you operate a Simba Voice voice agent, you are typically the "controller," "business," or equivalent of personal data relating to your Recipients (you decide who to contact, what to say, and on what legal basis), and Speechify processes that data on your behalf as a service provider or processor. Where required, the parties will enter into a data processing addendum on Speechify's standard terms governing that relationship. You are responsible for providing any privacy notices and obtaining any consents required of a controller, including under the California Consumer Privacy Act / California Privacy Rights Act and other applicable U.S. state privacy laws.

Recordings and AI-processed calls

As described in Section 4, where you record, transcribe, or process calls using Simba Voice, you are responsible for obtaining any consent required by federal or state wiretap and recording-consent laws and for providing the disclosures required of you. Speechify may, separately and in its capacity as the operator of the platform, retain recordings, transcripts, and metadata in accordance with this Policy and applicable law.

Sub-processors

Twilio, Inc. acts as a processor or sub-processor to Speechify in delivering Simba Voice. A current list of material sub-processors used in connection with Simba Voice is available on request from [email protected].

Retention

We retain voice and messaging data for the period required to provide the service, to perform any feature you have configured (such as call summaries or follow-up), to comply with our legal, tax, audit, and dispute-defense obligations, and to address fraud, abuse, and security investigations. After that period we delete or de-identify the data. You may also configure shorter retention or deletion of specific data through Simba Voice product controls where available.

Your privacy rights

Where you are an individual with rights under U.S. state privacy laws (for example, California, Colorado, Connecticut, Virginia, Utah, or others as those laws come into effect), you may exercise those rights as described in the Speechify Privacy Policy. Recipients of calls or messages should generally direct their privacy requests to you as the controller; we will reasonably cooperate with you to support those requests.

Monitoring

You acknowledge and agree that Speechify and our carriers may monitor, log, scan, and analyze traffic associated with Numbers — including metadata and, where reasonably necessary, content — to detect, investigate, and prevent fraud, abuse, security incidents, or violations of this Policy or applicable law, and to comply with lawful requests from regulators or carriers. We will treat any such data in accordance with this Section 7 and applicable law.

8. Suspension, Investigation, and Termination

We may suspend or terminate your access to any Number, or to Numbers generally, immediately and without prior notice if we reasonably determine that (a) your traffic violates this Policy, the Terms, applicable law, or any carrier rule; (b) your traffic threatens the integrity, security, performance, or reputation of Speechify, our carriers, or the broader telephone network; (c) we receive a credible complaint, regulatory order, court order, or carrier directive; (d) your account is delinquent; or (e) continued service would expose Speechify to material risk.

We may, but are not obligated to, give you an opportunity to cure. On termination of your account, your right to use any Numbers ends immediately, and we may release the Numbers back into the available pool.

9. Fees, Carrier Charges, and Taxes

Fees for provisioning, holding, and using Numbers are described in the Simba Voice pricing pages or in your order form. In addition to those fees, you are responsible for: (a) carrier surcharges, regulatory recovery fees, USF contributions, 911 fees, A2P registration fees, and other pass-through telecom charges; and (b) sales, use, telecommunications, and similar U.S. federal, state, and local taxes levied on your use of a Number. Where required by law, we will collect and remit such taxes; otherwise, you are responsible for self-assessment and remittance.

10. Indemnification

In addition to and without limiting Section 5 of the Terms, you agree to defend, indemnify, and hold harmless Speechify and its officers, directors, employees, agents, affiliates, carriers (including Twilio), and licensors from and against any and all claims, demands, regulatory investigations, fines, penalties, losses, liabilities, damages, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your use of any Number; (b) any call, message, recording, transcript, or voicemail associated with a Number; (c) your breach of this Policy, the Terms, applicable law, or any carrier rule or pass-through policy referenced here; (d) any claim that your use of a Number infringes, misappropriates, or violates the rights of any person, including privacy, publicity, intellectual-property, or consumer-protection rights; and (e) any fines, penalties, or pass-through charges imposed on Speechify by a carrier, regulator, or numbering authority because of your traffic.

11. Disclaimers and Limitation of Liability

Telephony is a best-effort service. We do not guarantee that any Number will be available, will deliver any particular call or message, will reach any particular destination, will display any particular caller ID, or will be free from interruption, blocking, filtering, mislabeling (for example as "Spam Likely"), or carrier-imposed restriction. Numbers are provided "AS IS" and "AS AVAILABLE", and to the maximum extent permitted by law we disclaim all warranties, express, implied, statutory, or otherwise, with respect to Numbers, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, and uninterrupted operation.

The limitation-of-liability and damages-cap provisions in the Terms apply to this Policy and to any claim arising from your use of a Number.

12. Governing Law, Dispute Resolution, and Modifications

The governing-law, arbitration, class-action waiver, jury-trial waiver, and venue provisions of the Terms (Florida law; arbitration with venue in Miami-Dade County, Florida for any non-arbitrable claim) apply to any dispute arising under this Policy. Where the law of your jurisdiction grants you non-waivable consumer-protection rights, those rights are not affected by this Policy.

We may modify this Policy from time to time. When we do, we will update the "Effective" date at the top of this page and, if the change is material, give notice in the manner described in the Terms. Your continued use of any Number after the effective date of an updated Policy constitutes acceptance of the update.
