Say

Terms of Service

Effective Date: April 1st 2026

Last Updated: April 1st 2026

Welcome to Say. These Terms of Service ("Terms") are a legal agreement between you and KeptHuman ("we," "us," or "our"). They govern your use of the Say mobile application and related services (collectively, the "Service").

By creating an account or using Say, you agree to be bound by these Terms. If you do not agree, please do not use the Service.

1. About Say

Say is a messaging app for one-on-one and small group conversations. It lets you send text messages, and it also offers AI-powered voice features: when you provide a voice sample, the app can generate audio from your typed messages using voice synthesis technology. There are no public profiles, no feeds, and no way for strangers to discover your account.

2. Eligibility

You must be at least 13 years old to use Say. If you are between 13 and 18 (or the age of majority in your jurisdiction), you may only use the Service with the consent of a parent or legal guardian who agrees to these Terms on your behalf.

Voice features require you to be at least 16 years old due to the nature of voice data processing. If you are between 16 and 18, you may use voice features only with parental or guardian consent. If you are under 16, you may not provide a voice sample.

By using the Service, you represent and warrant that you meet these eligibility requirements.

3. Your Account

3.1 Account Creation

You sign in using Apple Sign-In or Google Sign-In. We do not create or store passwords. Your account is tied to the authentication provider you choose.

3.2 Account Security

You are responsible for maintaining access to the device and authentication method (Apple ID or Google account) you use to sign in. You are responsible for all activity that occurs under your account. If you believe your account has been compromised, please contact us immediately.

3.3 Account Accuracy

You agree to provide accurate information for your profile (such as your display name). You may not impersonate another person or create an account on behalf of someone who has not authorized you to do so.

3.4 Account Deletion

You may delete your account at any time from within the app. When you delete your account:

Your profile information is removed.
Your voice profile is deleted, and we instruct Cartesia to delete it from their systems.
Any stored voice samples are permanently deleted.
Your messages and previously delivered generated audio associated with those messages are deleted from conversations.
Account deletion is permanent and cannot be reversed.

We aim to process account deletion requests within 30 days. We may retain certain information after deletion as required by law or for legitimate business purposes (such as resolving disputes or enforcing these Terms), as described in our Privacy Policy.

4. Friend Connections

Say does not have public profiles, search, or discovery features. You connect with friends by sharing a personal friend code (format: SAY-XXXXXX). By sharing your friend code with someone, you are inviting them to connect with you on Say. You are responsible for sharing your code only with people you intend to communicate with.

Once you connect with someone, your display name and profile photo are visible to them in conversations. The same applies to other members of any group conversation you join. You are responsible for choosing whether to join a group and for the display name and profile photo you use on the Service.

5. Voice Features and AI Processing

This section explains how Say uses artificial intelligence to create and process voice-related content. Please read it carefully.

5.1 Consent to Voice Processing

By choosing to provide a voice sample, you give your informed, affirmative consent to the processing described in this section. You may withdraw this consent at any time by deleting your voice profile from within the app.

You may only provide a voice sample of your own voice. You may not record or upload another person's voice as your voice sample.

5.2 Voice Samples and Voice Profiles

When you provide a voice sample — a short recording of your voice — it is uploaded to our cloud infrastructure and sent to Cartesia, a third-party AI provider, which creates a voice profile based on your sample. A voice profile is a digital representation that enables the generation of speech that sounds like your voice.

After your voice profile has been created, the original voice sample recording is deleted from our servers. Your voice profile is retained by Cartesia for as long as you use the voice features or until you delete it.

5.3 Biometric Data Notice

Your voice sample and voice profile may be classified as biometric data under certain laws, including the Illinois Biometric Information Privacy Act (BIPA), the Texas Capture or Use of Biometric Identifier Act (CUBI), and similar legislation in other jurisdictions.

By providing a voice sample, you consent to the following:

Purpose: Your voice data is collected and processed solely to create a voice profile and generate audio within the Say messaging application. It is not used for any other purpose.
Processing: Your voice sample is sent to Cartesia, a third-party provider, for voice profile creation.
Retention: Your voice profile is retained only for as long as you actively use the voice features or until you request deletion, whichever comes first. The original voice sample is deleted from our servers after your voice profile is created.
Deletion: You may delete your voice profile at any time through the app. Upon deletion, we instruct Cartesia to delete it as well.
No sale or trade: We do not sell, lease, or trade your biometric data to any third party.

You may revoke this consent at any time by deleting your voice profile in the app.

5.4 Generated Audio

When you type a message in a conversation where voice features are active, your message text is sent to Cartesia, which uses your voice profile to produce generated audio — a synthesized audio version of your typed message.

Generated audio is computer-generated speech. It is not a real recording of you speaking.

Generated audio files are stored in our cloud infrastructure and are accessible only to the participants of the conversation in which they were sent.

5.5 Emotion Detection

To make generated audio sound more natural, message text may be sent to OpenAI, a third-party AI provider, for emotion detection. This analysis identifies the emotional tone of your message (for example, whether it sounds happy, serious, or excited) so that the generated audio can better reflect that tone. OpenAI processes the text solely for this purpose. Under our data processing agreement with OpenAI, this data is not used to train their models.

5.6 Language Support

Voice synthesis is available in 42 languages. The language used for generating audio depends on the language of your message text.

5.7 Your Control Over Voice Data

You have full control over your voice data:

You may delete your voice profile at any time from within the app.
When you delete your voice profile, we instruct Cartesia to delete it from their systems as well.
Deleting your voice profile means new generated audio can no longer be created in your voice.
Previously generated audio that was already delivered in conversations will remain accessible to conversation participants unless those participants delete the conversation or you delete your account.
Deleting your account (Section 3.4) automatically triggers deletion of your voice profile.

5.8 Important Acknowledgments

By using the voice features, you acknowledge and agree that:

Your voice sample will be processed by Cartesia (a third-party provider) to create a voice profile.
Your message text will be processed by Cartesia for audio generation and by OpenAI for emotion detection.
Generated audio is synthetic speech produced by AI — it is not a real recording of your voice.
Other participants in your conversations will receive generated audio that sounds like your voice but was produced by AI.
If you share generated audio with anyone outside of Say, you are responsible for making clear that it is AI-generated and not a real recording.

6. Acceptable Use

You agree not to use Say to:

Harass, bully, threaten, or intimidate any person.
Send content that is illegal, hateful, defamatory, obscene, or promotes violence.
Send, request, or distribute any content that sexually exploits or endangers minors.
Impersonate another person, or use the voice features to create generated audio that impersonates someone else without their explicit consent.
Provide another person's voice as your voice sample, or use anyone else's voice without their knowledge and informed consent.
Distribute generated audio outside of Say in a way that is misleading, deceptive, or harmful — including representing generated audio as a real recording of someone speaking.
Use the Service for fraud, phishing, spam, or any other deceptive purpose.
Attempt to reverse-engineer, decompile, disassemble, or extract source code from the app, except to the extent that applicable law expressly permits this activity and it cannot be waived by agreement.
Interfere with or disrupt the Service, its servers, or its networks.
Use automated tools, bots, or scripts to access the Service.
Circumvent any security, rate-limiting, or access-control features of the Service.
Use the Service in any way that violates applicable law or regulation.

We may investigate potential violations and, at our discretion, suspend or terminate your account if we reasonably believe you have violated these Terms. We may also report illegal activity to law enforcement where we are required or permitted to do so.

7. Content Ownership and Licenses

7.1 Your Content

You retain ownership of the content you create and share through Say, including your messages and voice samples ("Your Content").

By using the Service, you grant us a limited, non-exclusive, worldwide, royalty-free license to host, process, store, and transmit Your Content solely as necessary to operate and provide the Service to you and the recipients of your messages. This includes sending Your Content to our third-party processors (Cartesia and OpenAI) as described in Section 5. This license ends when you delete the relevant content or your account, except as needed to complete operations already in progress or as required by law.

We do not claim ownership of Your Content. We do not use Your Content to train AI models, and we do not currently use Your Content for advertising.

7.2 Generated Audio

Generated audio is produced by AI using your voice profile and your message text. You own the messages you type. We grant you a personal, non-exclusive, non-transferable right to listen to and share generated audio within the Service as part of normal use. You may not use generated audio for commercial purposes, to deceive or mislead others, or in any way that violates these Terms.

7.3 Copyright Complaints

We respect intellectual property rights. If you believe that content on the Service infringes your copyright, please contact us at legal@kepthuman.com with the following information:

A description of the copyrighted work you claim has been infringed.
A description of where the allegedly infringing content is located within the Service.
Your contact information (name, address, email, phone number).
A statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law.
A statement, under penalty of perjury, that the information in your notice is accurate and that you are the copyright owner or authorized to act on their behalf.
Your physical or electronic signature.

We will respond to valid copyright notices in accordance with applicable law, including the Digital Millennium Copyright Act (DMCA).

7.4 Our Intellectual Property

Say, its name, design, features, code, trademarks, and logos are owned by KeptHuman or its licensors and are protected by intellectual property laws. Nothing in these Terms grants you any right to use our trademarks, trade names, or branding without our prior written consent.

8. Privacy

Your privacy is important to us. Our Privacy Policy explains what information we collect, how we use it, and your rights regarding your data. The Privacy Policy is incorporated into these Terms by reference.

Key highlights:

We collect only the information necessary to provide the Service.
Voice samples and message text are processed by third-party AI providers (Cartesia and OpenAI) as described in Section 5.
We use Firebase (Google) for backend services and Apple/Google for authentication.
We use Firebase Cloud Messaging for push notifications.
We do not sell your personal data.
You can request deletion of your data at any time.

9. Third-Party Services

Say relies on the following third-party services to operate:

Cartesia — voice profile creation and voice synthesis (text-to-speech).
OpenAI — emotion detection in message text for more natural voice synthesis.
Firebase (Google) — backend infrastructure, data storage, and push notifications.
Apple / Google — authentication via Sign-In with Apple or Google Sign-In.

These providers operate under their own terms of service and privacy policies. We select our providers carefully and maintain data processing agreements with them. However, we are not responsible for any third-party provider's independent actions, outages, or policy changes. By using Say, you acknowledge that your data will be processed by these providers as described in these Terms and our Privacy Policy.

10. Availability and Changes to the Service

We strive to keep Say available and reliable, but we cannot guarantee uninterrupted or error-free access. The Service may be temporarily unavailable due to maintenance, updates, or circumstances beyond our control.

We may modify, update, suspend, or discontinue any part of the Service at any time. If we make changes that materially reduce the core functionality of the Service, we will make reasonable efforts to notify you in advance (for example, through an in-app notice or push notification).

11. Termination

11.1 By You

You may stop using Say at any time. You may delete your account as described in Section 3.4.

11.2 By Us

We may suspend or terminate your account if:

You violate these Terms or the Acceptable Use policy in Section 6.
We are required to do so by law or legal process.
Your conduct creates risk or legal exposure for us, other users, or third parties.
Your account has been inactive for an extended period (we will notify you before taking action for inactivity).
We discontinue the Service entirely.

If we terminate your account for a Terms violation, we will make reasonable efforts to notify you and explain the reason, unless doing so would compromise safety, security, or a legal obligation.

11.3 Effect of Termination

Upon termination, your right to use the Service ends immediately. We will delete your account data in accordance with our Privacy Policy and Section 3.4. The following sections survive termination: Sections 7, 12, 13, 14, 15, and 17.

12. Disclaimers

We want to be upfront about what we can and cannot guarantee. The legal language below is standard and required to protect both you and us.

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. TO THE FULLEST EXTENT PERMITTED BY LAW, KEPTHUMAN DISCLAIMS ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

In plain terms, this means:

We do not guarantee that the Service will be error-free, always available, or completely secure.
We do not guarantee the accuracy, quality, or fidelity of generated audio. Voice synthesis technology has inherent limitations, and generated audio may not sound exactly like your voice.
We do not guarantee that third-party services (Cartesia, OpenAI, Firebase) will operate without interruption or error.
We are not responsible for how other users or third parties may use or share content within or outside the Service.

13. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW:

KeptHuman, its officers, directors, employees, and affiliates will not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, reputation, goodwill, or other intangible losses, arising out of or related to your use of (or inability to use) the Service, regardless of the theory of liability (contract, tort, strict liability, or otherwise).

Our total aggregate liability to you for all claims arising out of or related to these Terms or the Service is limited to the greater of (a) the amounts you have paid us in the 12 months preceding the claim, or (b) one hundred U.S. dollars ($100 USD).

These limitations apply even if we have been advised of the possibility of such damages and even if a remedy set forth herein is found to have failed its essential purpose.

Some jurisdictions do not allow the exclusion or limitation of certain damages. In those jurisdictions, our liability is limited to the maximum extent permitted by law.

14. Indemnification

To the extent permitted by applicable law, you agree to indemnify, defend, and hold harmless KeptHuman and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or related to:

Your use of the Service in violation of these Terms.
Your Content, including any generated audio created using your voice profile.
Your violation of any applicable law or any third party's rights.
Any dispute between you and another user of the Service.

15. Dispute Resolution

15.1 Informal Resolution First

We prefer to resolve disputes without litigation. Before filing any formal legal proceeding, you agree to contact us at legal@kepthuman.com and attempt to resolve the dispute informally. We will work with you in good faith for up to 60 days. If the dispute is not resolved within that period, either party may proceed as described below.

15.2 Governing Law

These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to conflict-of-law principles.

15.3 Arbitration

Any dispute that is not resolved informally shall be resolved through final and binding arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules. Arbitration will be conducted in English.

If you are an individual consumer, the AAA's Consumer Arbitration Rules apply. We will pay all arbitration filing fees and administration costs beyond the initial filing fee you would pay for a court action. Each party will bear its own attorneys' fees unless the arbitrator determines that a claim or defense was frivolous, in which case the arbitrator may award reasonable fees to the prevailing party.

The arbitrator's decision will be final and binding and may be entered as a judgment in any court of competent jurisdiction.

15.4 Class Action Waiver

You and KeptHuman each agree that any dispute resolution will be conducted only on an individual basis and not as a class, consolidated, or representative action. If a court or arbitrator finds that this class action waiver is unenforceable as to a particular claim, then that claim (and only that claim) must be severed from the arbitration and may proceed in court, while the remaining claims shall continue in arbitration.

15.5 Exceptions

Either party may bring a claim in small claims court if the claim qualifies. Either party may seek injunctive or equitable relief in any court of competent jurisdiction to protect intellectual property rights or to prevent imminent, irreparable harm.

15.6 Opt-Out

You may opt out of the arbitration and class action waiver provisions by sending written notice to legal@kepthuman.com within 30 days of first accepting these Terms. Your notice must include your name, your Say account information, and a clear statement that you wish to opt out. If you opt out, disputes will be resolved in the state or federal courts located in Delaware.

16. Changes to These Terms

We may update these Terms from time to time. When we make material changes, we will:

Update the "Last Updated" date at the top of this page.
Notify you through the app or by other reasonable means at least 14 days before the changes take effect, unless the change is urgently required by law.

Your continued use of the Service after the updated Terms take effect means you accept the changes. If you do not agree with the updated Terms, you should stop using the Service and may delete your account.

17. General Provisions

17.1 Entire Agreement

These Terms, together with our Privacy Policy, constitute the entire agreement between you and KeptHuman regarding the Service and supersede all prior agreements, understandings, and representations on this subject.

17.2 Severability

If any provision of these Terms is found to be invalid or unenforceable by a court of competent jurisdiction, that provision will be enforced to the maximum extent permissible, and the remaining provisions will remain in full force and effect.

17.3 No Waiver

Our failure to enforce any right or provision of these Terms does not constitute a waiver of that right or provision. Any waiver must be in writing and signed by KeptHuman to be effective.

17.4 Assignment

You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign our rights and obligations under these Terms in connection with a merger, acquisition, reorganization, or sale of all or substantially all of our assets, or by operation of law, without your consent but with notice to you. Any purported assignment in violation of this section is void.

17.5 Force Majeure

We are not liable for any delay or failure to perform resulting from causes beyond our reasonable control, including but not limited to natural disasters, war, terrorism, pandemic, labor disputes, government actions, internet or telecommunications failures, power outages, or failures of third-party services.

17.6 Electronic Communications

By using the Service, you consent to receive communications from us electronically, including through in-app notices, push notifications, and emails to the address associated with your account. You agree that all agreements, notices, disclosures, and other communications we provide electronically satisfy any legal requirement that such communications be in writing.

17.7 Notices

We may send you notices through the app, via push notification, or to the email address associated with your account. You are responsible for keeping your contact information current. Notices sent electronically are considered delivered when sent.

17.8 No Third-Party Beneficiaries

Except as expressly stated in Section 17.9 (Apple App Store Terms), these Terms do not create any third-party beneficiary rights in any individual or entity that is not a party to these Terms.

17.9 Apple App Store Terms

If you downloaded Say from the Apple App Store, the following additional terms apply:

These Terms are between you and KeptHuman, not Apple Inc. ("Apple"). KeptHuman, not Apple, is solely responsible for the Service and its content.
Apple has no obligation to provide any maintenance or support services for the Service.
If the Service fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price (if any) to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to the Service.
Apple is not responsible for addressing any claims by you or any third party relating to the Service or your possession and use of the Service, including but not limited to: (a) product liability claims, (b) any claim that the Service fails to conform to any applicable legal or regulatory requirement, and (c) claims arising under consumer protection, privacy, or similar legislation.
In the event of any third-party claim that the Service or your possession and use of the Service infringes that third party's intellectual property rights, KeptHuman, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such intellectual property infringement claim.
Apple and its subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
