This page describes how end users consent to receive SMS messages from the Nimbus Weather Alerts program operated by Nimbus Watch LLC. It is provided for public reference and for review by mobile carriers and The Campaign Registry.
Program
- Program name: Nimbus Weather Alerts
- Brand: Nimbus Watch LLC
- Purpose: Deliver lightning detection and severe-weather safety alerts to workers assigned to monitored job sites.
- Message type: Transactional safety notifications (not marketing).
How consent is collected
End users are individual workers assigned to job sites monitored by Nimbus Watch. Consent is collected through a confirmed, double opt-in SMS flow:
- A company enters a service agreement with Nimbus Watch LLC. A site administrator at that company signs in to the Nimbus Watch dashboard at app.nimbus.watch and adds a worker to a job site by entering the worker's name and mobile number.
- Before any alerts are sent, Nimbus Watch sends the worker a single confirmation SMS that identifies the sender, describes the program, links to these Terms and Privacy Policy, and requires the worker to reply YES to enroll.
- The worker is enrolled only after they reply YES. The consent timestamp, message ID, and source are logged. Workers who do not reply YES receive no further messages.
- Workers can reply STOP at any time to opt out and HELP for assistance.
What the flow looks like
The screenshot below shows the admin's "Add Worker" view in the Nimbus Watch dashboard alongside the confirmation SMS the worker receives and their YES reply.
