Messaging terms
These terms govern text messages sent by Sentr and by businesses using Sentr to reply to the people who contact them.
01
Program description
Sentr Alerts sends transactional and conversational text messages on behalf of a business you contacted. Messages relate to an enquiry you made, an appointment you asked about, or a reply to something you sent that business first.
Businesses using Sentr choose how much it does on their behalf, from recording a conversation without replying, through to answering and offering appointment times. In every mode, messages come from the business you contacted.
02
Message frequency
Message frequency varies. Messages are sent in response to your enquiry, so the number you receive depends on the conversation. There is no recurring broadcast or marketing sequence.
03
Cost
Message and data rates may apply. Charges depend on your mobile plan and are billed by your carrier. Sentr does not charge you to receive or send messages.
04
Help, stop, and start
These keywords work at any time, on any message in the programme, and are case-insensitive.
- HELP replies with the programme name and how to reach support. You can also email support@sentrusa.com, or text or call 408-459-8291.
- STOP opts you out immediately. You will receive one confirmation that no further messages will be sent, and then nothing more from that business through Sentr.
- START resumes messages after you have opted out, if you later want to continue the conversation.
UNSTOP, UNSUBSCRIBE, CANCEL, END and QUIT are also honoured as opt-out keywords.
Consent to receive text messages is not a condition of any purchase.
05
Carriers
Carriers are not liable for delayed or undelivered messages. Delivery is subject to your carrier’s network and to your handset being able to receive messages.
06
Your mobile information
No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Information sharing to subcontractors in support services, such as customer service, is permitted. All other use case categories exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties.
Consent to receive text messages is never a condition of purchase, and your number is never sold.
