Terms of service.

The ground rules for using UIMessage. We've kept them as plain as we can.

Last updated: November 10, 2026

1. Accepting these terms

By creating an account or using UIMessage, on any device or on UIMessage Web, you agree to these terms, to our Community Guidelines, and to the way our Privacy Policy describes how we handle information. If you don't agree, please don't use UIMessage. UIMessage is made by IntrSI (“we”, “us”).

2. Who can use UIMessage

You must be at least 13 years old, or older where the law of your country says so, and able to agree to these terms. You may not use UIMessage if we have banned you, or if the law where you live forbids it.

3. Your account

You sign up with a phone number you own and can receive text messages on. You're responsible for what happens on your account and for keeping your devices secure: don't share your sign-in code or your two-step verification PIN with anyone, and sign out of any device you don't recognise in Profile → Devices.

Your messages are end-to-end encrypted and kept on your devices, not on our servers. If you lose all your devices or sign out, we can't restore your chats for you.

4. Acceptable use

Use UIMessage to talk to people who want to hear from you. Don't use it to break the law, send spam or malware, scam, harass, threaten or impersonate anyone, endanger children, infringe anyone's rights, or to disrupt the service, get around its security or get into accounts that aren't yours. Don't use bots, scripts or modified apps to send messages, place calls or create accounts. The Community Guidelines say more about each.

Because your messages are end-to-end encrypted, we can't see them. We act on what people report to us and on signals about how accounts are used, never on what anyone says.

5. Your content

What you create and send is yours. You give us only the limited permission needed to store your encrypted content until it is delivered and to pass it to the people you send it to, and to show your profile to the people your privacy settings allow. You're responsible for what you send, and for having the right to send it.

6. Decisions about accounts

If an account breaks these terms or the Community Guidelines, or to protect it or other people, we may put it under review, restrict it for a time or ban it. While that lasts, the account can't send or receive messages or calls. The app tells you why and, where a decision can be appealed, lets you ask for a review. How this works is in the Community Guidelines.

7. The service

UIMessage is free. We work hard to keep it reliable, but it is provided “as is” and “as available”. We may change, add or remove features, and set reasonable limits to protect the service and the people who use it. UIMessage needs a working phone number and an internet connection, and isn't a replacement for emergency services.

8. Our software and brand

UIMessage, its logo, its mascots and its software belong to IntrSI. We give you a personal, non-transferable licence to use the apps as these terms allow. These terms don't give you any right to our trademarks or branding.

9. Disclaimers and limitation of liability

To the fullest extent the law allows, UIMessage and IntrSI aren't liable for indirect, incidental, special or consequential damages, or for lost data, arising from your use of the service. Some places don't allow these limits, so some of them may not apply to you, and nothing here limits rights the law gives you that can't be limited.

10. Ending your use

You can stop using UIMessage at any time and delete your account on your phone in Profile → Account → Delete account, or ask us to delete it. We may end or suspend access if you break these terms, or to protect the service and the people who use it.

11. Changes to these terms

We may update these terms. The date at the top shows the current version; when a change matters, we'll also tell you in the app. Using UIMessage after a change means you accept the new terms.
