SMS alerts — opt-in & consent

MachineGuardian sends authenticated customer staff (typically maintenance, reliability, and operations personnel at industrial plants) a text-message alert when a piece of their ownmonitored rotating equipment — pumps, blowers, motors, gearboxes — crosses a condition threshold they configured (e.g. a critical bearing-vibration alarm). These are transactional service alerts. We do not send marketing, promotional, or third-party content over this channel.

• Program name: MachineGuardian Equipment Alerts
• Operator: NorthStar Industries
• Message frequency: varies with equipment condition; typically up to one message per day per critical alert
• Cost: message and data rates may apply
• Opt-out: reply STOP to any message, or un-check the consent box in the app
• Help: reply HELP to any message, or email [email protected]

MachineGuardian is a B2B service. Only authenticated MachineGuardian users — maintenance and reliability staff at customer organizations — can opt in to SMS alerts. There is no public sign-up form for SMS, no keyword opt-in, and no third-party opt-in source. Because the opt-in screen lives inside the authenticated application, we reproduce the entire consent screen below so reviewers and prospective users can read every required disclosure on this public page.

1. An authorized user signs in at https://www.machineguardian.io.
2. They open Notifications → SMS alerts from the navigation.
3. They enter their own mobile number in E.164 format (e.g. +12025551234).
4. They check an explicit, un-checked-by-default consent box containing the verbatim language shown below. No SMS is ever sent until that box is checked.
5. They subscribe to one or more specific pieces of equipment and choose a minimum severity threshold (e.g. alarm, critical).
6. An alert fires only when that equipment crosses the chosen threshold. A built-in dedup window prevents repeats of the same event kind.

Below is a faithful, non-functional reproduction of the consent form an authenticated user sees inside the application at /admin/notifications. The text, layout, and checkbox state shown here are exactly what a user must agree to before any SMS is sent.

The reproduction above is read-only on this public page. The interactive version that actually opts a user in lives inside the authenticated application.

Every alert is branded with [MachineGuardian], identifies the affected equipment, describes the threshold crossing, links the operator to the live dashboard, and includes the STOP / HELP keywords required by carrier policy.

• STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, QUIT — immediately stops all further messages and replies with a confirmation: “You have been unsubscribed from MachineGuardian Equipment Alerts and will receive no further messages. Reply START to resubscribe.”
• HELP, INFO — replies with: “MachineGuardian Equipment Alerts: transactional equipment-condition alerts. Msg & data rates may apply. Reply STOP to unsubscribe. Support: [email protected].”
• START, UNSTOP — resumes messages for a user who previously sent STOP, provided they still hold an active consent in the application.

Consent is collected solely for this program. Mobile numbers and SMS opt-in data are never sold, rented, traded, or otherwise shared with third parties or affiliates for marketing or promotional purposes. The only third-party processor that ever touches a phone number is the SMS gateway provider (Twilio), which delivers the message itself; the message body never contains sensitive information beyond the equipment identifier and the threshold-crossing details. Full details are in our Privacy Policy and Terms of Service (§4: SMS messaging program & opt-in).
