Retrospective meal-impact reports for Nightscout users

GlucoseLens Alerts

Text message alerts

GlucoseLens can send a text when a glucose reading crosses a threshold and is still moving. Messages go to a person the account holder nominates — often themselves, often someone they trust to help them keep an eye on things. This page explains exactly what is sent, how often, who agrees to what, and how to stop.

Not a safety or emergency system

These texts are not a safety or emergency system. They depend on a background sync that runs every few minutes and can be late, delayed, or skipped, and they may not arrive at all. Do not rely on them for low glucose or any urgent situation. For real-time alarms, use Nightscout's own alarm settings or your CGM's native alerts, which run on your device and do not depend on this app.

Nominate someone for text alerts

Include the country code, starting with a plus sign.

Used only in the message asking them to agree. A first name is enough, and is safer if a digit is mistyped.

You will be asked to sign in to finish. A number is only ever stored against the account it belongs to.

What you will receive

  • Glucose threshold alerts: when a reading is at or above 200 mg/dL and rising, or at or below 70 mg/dL and falling.
  • An optional daily summary of the previous day, if you turn it on.
  • One message with a link, when a number is first nominated, so the person holding it can decide for themselves.

A message states the reading, whether it is rising or falling, and a link to review it in the app. It never tells you what to do about it, and it never recommends a dose, a correction, or a treatment.

How often

Message frequency varies with your glucose. Most people receive a few messages per week. On a difficult day you might receive several, and in an unusual case as many as ten or more in one day.

These limits are enforced by the app:

  • Never more than one alert of the same kind within 30 minutes.
  • After an alert, the next alert of that kind normally waits 2 hours. That wait is shortened only if the reading gets significantly worse.
  • A reading that stays high or low without moving does not repeat an alert.

Cost

Message and data rates may apply. GlucoseLens does not charge for text messages; your mobile carrier may.

Stopping and getting help

Text STOP to any message to stop all texts immediately, without asking anyone first. Stopping is permanent for that number: to receive texts again the number has to be nominated again and agreed to again from a fresh link. The account holder can also remove a number at any time in Settings.

Text HELP to any message for help and contact information.

Carriers

Carriers are not liable for delayed or undelivered messages.

Who agrees, and how

The account holder chooses who receives these messages, but they cannot agree on that person's behalf. Nominating a number sends exactly one message to it: a short note saying who asked for the alerts and a link to a page written for the person receiving them.

That page explains what will be sent and how often, and asks them to agree for themselves. Until they do, nothing further is sent to the number. If they would rather not, they can decline on that page or reply STOP, and the number is discarded.

Anyone receiving these messages is seeing another person's glucose readings. That is the point of the feature, and it is why the person holding the phone is the one who decides.

Consent is optional

Agreeing to texts is not required to use GlucoseLens, and we do not sell or share your phone number. See the Terms of Service and Privacy Policy.
