Privacy
Cairn is operated by CMD+RVL. When you text Cairn or enter your number, we store your phone number, the messages exchanged, and the details you give us during setup (your name, what you asked Cairn to watch, and an optional email).
We use this only to run the service: to set you up, to send you the alerts you asked for, and to answer you. We do not sell or share your phone number or message content with third parties for their marketing. Mobile opt-in data and consent are never shared with third parties.
Messages are delivered through Twilio, our SMS provider, which processes them under its own privacy policy.
Reply STOP at any time to opt out. To have your data deleted, email cairn@cmdrvl.com.
