Disclaimers

The short version: Glucogaze is a convenience display. It is not a medical device, and nothing it shows should change what you do about your diabetes.

Not a medical device

Glucogaze is for awareness only. It is not a medical device and must never be used to make treatment or dosing decisions. Readings can be delayed, incorrect or missing entirely — always confirm with your approved meter, your official CGM app, or your diabetes team before acting on a number.

Alerts are not alarms

Colour changes, notifications and any sound a screen makes are conveniences, not safety alarms. They can be late, wrong, or silently absent — a screen that has lost Wi-Fi looks calm, not alarmed. Keep the alarms on your CGM and phone switched on and configured. Nothing here replaces them.

What you see may be old

Glucogaze shows the last reading it managed to fetch. Wi-Fi drops, a sleeping laptop, a provider outage, an expired login or a rate limit can all freeze the display. We show the age of a reading for exactly this reason — check it. An absent update is not evidence that your glucose is steady.

Unofficial and unaffiliated

Glucogaze is not affiliated with, endorsed by or supported by Abbott, Dexcom, Nightscout, GeekMagic or any other provider. It reads data through unofficial interfaces that can change, break or stop working at any time without notice. Never rely on it for medical monitoring — keep using the official apps and alarms for anything that matters.

DIY — build at your own risk

This is a do-it-yourself project. You buy, assemble and flash the hardware yourself, and you do so entirely at your own risk. Flashing firmware can permanently disable a device and will usually void its warranty. Glucogaze accepts no responsibility for bricked, damaged or non-functioning hardware, or for any loss arising from building or using it.

Battery and electrical safety

Some builds use lithium-ion cells. Lithium batteries can overheat, vent or catch fire if they are damaged, short-circuited, over-charged or wired incorrectly. Use protected cells and a suitable charger, never charge unattended or on a flammable surface, and give any enclosure adequate ventilation. You are responsible for building, powering and siting your device safely.

Not for emergencies

Glucogaze cannot summon help and is not monitored by anyone. If you or someone you look after is unwell, treat it using your usual plan. In an emergency call 999, or 111 for urgent advice that is not an emergency.

Personal project, provided as is

Built and maintained by one person in their spare time. Features may change or break while the project is in active development. Everything here is provided “as is”, without warranty of any kind, and to the fullest extent the law allows no liability is accepted for any loss, injury or damage arising from its use.

1. What Glucogaze is

Glucogaze is a consumer display project. It takes glucose data that already exists in a third-party continuous glucose monitoring (CGM) service you have chosen and connected, and it presents that data on a small always-on screen and on this website.

It is intended for information and convenience only. It is not intended to diagnose, treat, cure, mitigate or prevent any disease or condition, and it is not intended to be used as the basis for any clinical or treatment decision.

2. It is not a medical device

Glucogaze is not a medical device. It has not been assessed, certified, approved or registered by the Medicines and Healthcare products Regulatory Agency (MHRA), by any UK Approved Body or EU Notified Body, by the US Food and Drug Administration (FDA), or by any other regulator anywhere in the world. None of its screens, alerts or statistics have been clinically validated.

Your CGM sensor, reader, pump and their official apps are regulated medical devices. Glucogaze is not a replacement for any of them, nor for the display, alarms or data those devices and apps provide. Treat Glucogaze as a secondary, unregulated view of data whose authoritative source lies elsewhere.

3. Never make treatment decisions from Glucogaze

Do not use anything displayed by Glucogaze to make a medical or treatment decision. That includes — without limitation — dosing or adjusting insulin or any other medication, deciding whether to eat or to treat a hypo, deciding whether to drive, and deciding whether to seek or delay medical help.

Before you act on a glucose number, confirm it using your approved blood glucose meter, your official CGM app or reader, or another method your clinician has recommended. If what Glucogaze shows disagrees with how you feel, believe how you feel and test.

4. Alerts, colours and sounds are not alarms

Glucogaze can change colour, raise an in-app notification, or make a sound when a reading crosses a threshold you have set. These are conveniences. They are delivered on a best-effort basis over consumer internet connections and unofficial data interfaces, and they can be delayed, duplicated, wrong, or absent altogether.

A failure is usually silent: if a screen loses Wi-Fi, if a source login expires, or if a provider blocks our requests, the display simply stops changing. It does not announce that it has stopped. You must not use the absence of an alert as evidence that glucose is in range.

The alarms built into your CGM system exist for safety and are regulated for that purpose. Keep them enabled and correctly configured. Do not switch them off or turn them down because Glucogaze is running.

5. The data comes from third parties we do not control

Glucogaze reads data through integration methods provided by, or reverse-engineered from, third-party services — including services such as FreeStyle LibreLink Up and Nightscout. Those integrations are not provided, endorsed, supported or controlled by the CGM manufacturers or by the maintainers of those services.

We make reasonable efforts to keep the connections working, but we do not control those systems and cannot guarantee that data will be available, current, complete or accurate. Providers may change, restrict, rate-limit or withdraw access at any time and without notice, and any such change may reduce, interrupt or permanently end Glucogaze’s ability to show your data. This is expected behaviour for an unofficial integration, not a defect.

6. Delay, gaps and error are normal

Information displayed by Glucogaze may be delayed, incomplete or unavailable because of connectivity problems, provider outages, sensor warm-up periods, rate limiting, expired credentials, power cuts or changes made by third-party platforms. Values may also be rounded or converted between mmol/L and mg/dL for display. Accordingly Glucogaze must not be relied upon for real-time monitoring or for any time-critical or safety-critical decision.

7. This is a DIY project and you build it at your own risk

Glucogaze is a do-it-yourself project. We do not sell, supply, distribute or import hardware. You choose and buy your own device from a third-party seller, you install our firmware on it yourself, and you site and power it yourself. Everything you do to that hardware, you do at your own risk.

  • Flashing third-party firmware can permanently disable a device and will usually void any manufacturer warranty and any right of return you had against the seller.
  • We have no relationship with the manufacturers or sellers of any device, and we make no representation about a device’s quality, safety, electrical compliance or fitness for any purpose.
  • Lithium-ion cells can overheat, vent or ignite if damaged, short-circuited, over-charged or wired incorrectly. Use protected cells and an appropriate charger, do not charge unattended or on a flammable surface, and ensure any enclosure is adequately ventilated.
  • You are responsible for complying with any law that applies to what you build, including electrical safety and radio equipment rules.

8. It is not monitoring, and it cannot get help

Nobody at Glucogaze watches your data. There is no monitoring service, no on-call clinician and no escalation path behind this project. Glucogaze cannot contact you, your carer, your clinic or the emergency services under any circumstances.

If you feel unwell, follow the plan agreed with your diabetes team. In an emergency call 999. For urgent advice that is not an emergency, call NHS 111 (or NHS 24 on 111 in Scotland).

9. Looking after someone else

If you use Glucogaze to follow another person’s glucose — a child, for example — everything above applies with equal force, and the responsibility for acting on that person’s care remains entirely with you and their clinical team. A remote display must never be the only thing standing between that person and a hypo.

Glucogaze is for personal and family use. It must not be used in a professional, clinical, care or institutional setting — a care home, school, nursery, clinic or workplace — as any part of looking after the people there. It has none of the validation, safeguards or support that such use would require.

10. Talk to a professional

Nothing on this site or on any Glucogaze screen is medical advice. If you have questions about your glucose levels, your diabetes management or your treatment plan, speak to your GP, your diabetes team or another suitably qualified healthcare professional. Never disregard professional advice, or delay seeking it, because of something Glucogaze displayed.

11. Accepting these disclaimers

By using Glucogaze — the website, the service or the firmware — you confirm that you have read and accepted this page, and that you understand and accept that:

  • Glucogaze is for informational and convenience purposes only;
  • data is sourced from third-party services outside our control;
  • interruptions, delays and inaccuracies will occur;
  • all medical decisions must be made using approved devices and in consultation with a qualified healthcare professional; and
  • you build, flash, power and site any hardware entirely at your own risk.

These disclaimers form part of our Terms of Service, which set out the legal limits of our liability — including the limits that the law does not permit us to exclude. If you do not accept any of this, please do not use Glucogaze.
