Automated technical alerts sent by private infrastructure-monitoring software to a small, fixed set of authorized recipients — the operator, and anyone the operator has designated to receive them. There is no public sign-up, no customer list, no purchased or rented data, and no marketing of any kind.
Messages are event-driven: one is sent when a monitored system fails, and when it recovers. A healthy system sends nothing at all.
Recipients' mobile telephone numbers, held in configuration on the operator's own servers. Alert content — a short technical description of a failure plus a timestamp — which describes computer systems, not people. Delivery metadata (message identifier, status, carrier, error code), held by our delivery provider.
Nothing else: no names, addresses, payment details, location, contacts, or device data.
A number is added only after that person has given the operator express permission, in writing, for example by email. We never add a number from a contact list, a directory, or a referral, and never obtain consent on anyone else's behalf.
There is no subscription system — no sign-up page, no web form, no join keyword, no subscriber database. Email the operator (section 7) to be added or removed; only the operator can change the configuration.
Separately, replying STOP (or CANCEL, QUIT,
OPTOUT, UNSUBSCRIBE, STOPALL, REVOKE,
END) makes our delivery provider stop messages to your number immediately;
HELP or INFO returns assistance, and START resubscribes.
This is applied by the carrier layer to every recipient, is required by US messaging rules, and
cannot be disabled by us. If you use a keyword, please also email the operator so the number is
removed at source.
Message frequency varies and is not fixed. Nothing is sent while monitored systems are healthy; during an incident alerts repeat about every five minutes until it is resolved. Most weeks there are no messages at all.
Message and data rates may apply. Delivery depends on your carrier and handset and cannot be guaranteed.
Solely to notify authorized recipients that monitored infrastructure has failed or recovered. Never for marketing, advertising, profiling, or analytics.
Shared only with our SMS delivery provider (Twilio) and the mobile carriers it transits, as far as is necessary to deliver a message. We do not sell, rent, license, or otherwise disclose recipients' numbers or message content to anyone else.
No mobile information or messaging consent will be shared with third parties or affiliates for marketing or promotional purposes.
Numbers are held only in server configuration and are deleted on request. Delivery metadata is retained by the delivery provider under its own schedule.
