SMS MessagingProgram.

Zentrr (operated by Sati Technology Inc.) sends account-security text messages to users who choose to protect their account with text-message two-factor authentication (2FA). The only messages we send through this program are one-time passcodes used to verify your identity when you sign in or when you add a phone number to your account.

This is a transactionalprogram. We do not send marketing, promotional, or recurring informational texts through it, and we never sell or share your mobile number or opt-in for anyone else's marketing.

A single 6-digit code each time identity verification is required. For example:

Messages are sent from Zentrr's toll-free number. The code is valid for a few minutes.

Text-message 2FA is strictly opt-in. We never enroll a phone number automatically. To turn it on, a signed-in Zentrr user takes these steps:

1. Open Profile → Security → Two-factor authentication in the Zentrr web application (app.zentrr.com).
2. Enter a mobile phone number and submit it.
3. Receive a verification code by text and enter it to confirm the number belongs to you.
4. Turn on the “Text message” method (tap Enable) to use SMS codes at sign-in.

By completing these steps you consent to receive the account-security text messages described on this page at the number you provided. Consent to receive texts is not a condition of using Zentrr — email and authenticator-app (TOTP) options are available.

You can stop the messages at any time, two ways:

1. Reply STOP to any message. You will receive a single confirmation that you have been unsubscribed, and we will send no further texts to that number.
2. In the app, open Profile → Security → Two-factor authentication, disable the “Text message” method, or remove the phone number from your profile.

To resume, re-enable text-message 2FA in your profile (or reply START).
