H33 Sign-In Text Messages: SMS Terms

H33.ai, Inc. · Version 2026-10-24 · Effective October 24, 2026

These SMS Terms apply to the text messages H33 sends to your mobile number. They are part of the H33 Terms of Service (https://h33.ai/legal/terms/2026-02-10/). Our Privacy Policy (https://h33.ai/legal/privacy/2026-02-10/) explains how we handle your information.

1. What we send

When you ask to sign in to H33, or to create an H33 account, using your mobile number, we text a one-time verification code to that number. These sign-in codes are the only text messages we send. We do not send marketing or promotional text messages.

2. Your consent

By entering your mobile number and asking for a code, you agree to receive that code by text message at that number. You are not required to receive text messages to buy anything from H33. Where another sign-in method is available to you (for example, a passkey), you can use it instead.

3. How often

One text message for each code you request. How many you receive depends on how often you sign in.

4. Cost

H33 does not charge for these messages. Message and data rates may apply under your mobile plan.

5. Help

Reply HELP for help, or email support@h33.ai.

6. Stopping messages

Reply STOP to stop all text messages from H33 to that number. We will confirm by text, and send nothing further to that number. After you reply STOP, we cannot text you sign-in codes. To receive them again, reply START, or contact support@h33.ai.

7. Numbers and carriers

Codes are sent to mobile numbers on supported carriers. Virtual, VoIP and toll-free numbers cannot receive codes. Mobile carriers are not liable for delayed or undelivered messages. A code is valid for a short time and only once. Never share a code with anyone. H33 will never ask you for it.

8. Privacy

We use your mobile number to send your sign-in codes and to protect your account, as described in our Privacy Policy. We do not sell your mobile number or share it with anyone for their marketing. Messages are delivered through our messaging provider, Amazon Web Services.

9. Changes

If we change these SMS Terms, we will publish the new version at a new address and keep this version unchanged at this address.
