MileBuck lets you sign in by sending one text message from your own phone. This page explains what you send, what we send back, how often, and how to stop.
Program name: MileBuck, operated by Narro LLC. Purpose: account sign-in. You start the conversation by texting us a one-time code from inside the app, and we reply once to confirm it. Nothing else is ever sent on this number.
The sign-in screen shows this text under the button before you tap it: one reply per sign-in, message and data rates may apply, reply HELP for help or STOP to opt out, with links to the Terms and the Privacy policy.

Every sign-in is the same two messages.
sign me in with code XXXXXX
verified! return to MileBuck to continue 🚗
Contact card: MileBuck
The contact card is attached to the first reply you ever receive, so you can save MileBuck and recognise the number next time. Later sign-ins get the confirmation alone.
One reply per sign-in. There are no recurring messages, no promotional messages, no reminders and no follow-ups. If you sign in again next year, you text us again and get one more confirmation.
Message and data rates may apply. Your carrier charges for the message you send and the one you receive under your plan. MileBuck does not charge for either.
Reply HELP to the MileBuck number for help, or email help@milebuck.com.
Reply STOP at any time to opt out. After that we send nothing to your number. Opting out does not delete your account. It does mean phone sign-in stops working for you, and you can still sign in with Apple or Google.
We keep your number as a one-way keyed fingerprint that lets us recognise you on your next sign-in, plus an encrypted copy and the last four digits so the app can show you which number is on the account. It is used for signing you in and for nothing else.
Mobile information will not be shared with third parties or affiliates for marketing or promotional purposes. Text messages are delivered through Twilio, which carries them for us and is not permitted to use your number for anything else.
The Terms of Use and the Privacy policy apply to signing in by text. Questions go to help@milebuck.com.
