These terms are the agreement between you and glyso. By using the app you accept them. They are written to be read, so please do.
glyso is a coaching app for people living with diabetes. It connects to the continuous glucose monitor you already wear, and it uses the readings — together with what you tell it about your meals, your insulin, your movement and your day — to explain what has already happened to your glucose and to help you spot patterns in it.
Concretely, glyso will:
That is a real product and we are not going to disclaim it into vagueness. It interprets. It makes calls. It is meant to be useful.
glyso is not a medical device. It is not registered, approved or certified as one anywhere, and it must not be used as one.
Specifically, and without exception:
Your CGM app and your clinical team remain the authority. Where glyso disagrees with either, they are right and glyso is wrong. If you feel unwell, if a reading does not match how you feel, or if something concerns you, treat according to what your team has told you and confirm with a finger-stick test. Do not wait for the app.
Being specific about this is more useful than a blanket disclaimer.
You need an account, and you need to be 16 or over to have one.
Keep your sign-in details to yourself. You are responsible for what happens under your account. Tell us if you think someone else has got into it.
One account is for one person’s data. glyso records whether you are setting it up for yourself or for someone you care for, but following another person’s readings is not a feature that exists yet — today an account holds the data of the person who set it up.
If you connect a sensor, you confirm that the account you are connecting is yours or that you have the wearer’s permission to use it. glyso signs in to your CGM provider as you, and your agreement with that provider still applies in full.
Do not use glyso to give medical advice to anyone else. Do not try to break, overload, scrape or reverse-engineer the service, or get at other people’s data. Do not use it in a way that breaks the law or your CGM provider’s own terms.
Do not log content that is not yours to log, and do not log anything unlawful or another person’s personal data without their agreement.
We apply rate limits and cost ceilings to keep the service running for everybody. If you hit one, ordinary use has probably not caused it.
How glyso handles your data is set out in the privacy policy, which forms part of these terms. The short version: it is yours, you can download all of it, you can delete all of it, and it is not sold or given to advertisers.
Your content stays yours. “Your content” means the things you put into glyso — your meal descriptions and photos, your journal answers, your logged doses and activities, the questions you ask, and your settings. You keep ownership of all of it. We do not claim it.
What you give us is permission to use it. So that glyso can work at all, you grant us a non-exclusive, worldwide, royalty-free licence to host, store, copy, transmit, adapt, analyse and process your content, and to allow our service providers to do the same on our behalf (the providers are listed in the privacy policy). That licence covers three things and no more:
The licence over your content lasts only as long as we hold the content. Delete your account and your content goes — your words, your photos, your journal answers, your settings and everything identifying — and the licence over it goes with it. It is not perpetual and it is not irrevocable, because those words would not be true of a product with a working delete button.
De-identified records and aggregated outputs are different, and the licence over those is permanent. Two things survive the deletion of your account:
Both are covered by section 7. We are separating them from your content deliberately rather than hiding them inside it, and the privacy policy sets out how to be excluded from either — which has to be asked for before you delete, because afterwards there is nothing left that could be matched to you.
We may sub-license and transfer this permission — to a service provider so it can do its job, and to a buyer if the business changes hands (section 14). We do not sell your content.
The software and everything behind it belongs to glyso. That includes the app and the backend; the brand, the name, the mascot and the design system; and — this is the part worth spelling out — the rulebooks and the models: the energy score and how it is computed, the glycaemic index tables, the meal-grading rules, the food-effect model, the community meal bank, and the statistics computed across users. None of that is licensed to you beyond your own personal use of the app, and none of it may be copied, extracted or rebuilt from what the app shows you.
The line between your data and our models is worth drawing precisely, because they are easy to confuse:
If you send us feedback, a suggestion or a bug report, we may use it freely and without owing you anything for it.
Some features are marked premium. There is no payment system in glyso today and nothing is being charged. If that changes, prices, billing terms and cancellation rights will be set out before you are asked to pay anything, and you will not be charged for something you did not agree to. Your statutory cancellation rights as a consumer will apply in full.
glyso is early. Features appear, change and are removed — several have already been. We may change, suspend or discontinue any part of the service, including a feature you rely on, and including the free tier. Where a change is significant and we can see it coming, we will tell you in the app in advance and — if it is a feature holding your data — give you time to export before it goes.
We aim to keep the service running but we do not promise it will always be available, or that it will be free of faults. Your CGM’s own app does not depend on glyso, which is the practical reason this is survivable.
Read this section. It is the one that decides what happens if something goes wrong.
10.1 — What we never limit. Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that the law does not allow us to limit or exclude. That exception is placed first because this is a health-adjacent product and it matters more here than the rest of the section.
10.2 — Your consumer rights are untouched. If you are a consumer, nothing in these terms affects your statutory rights, including your rights under the Consumer Rights Act 2015 that digital content be of satisfactory quality, fit for purpose and as described. We cannot contract out of those and we are not trying to.
10.3 — What glyso is not responsible for. Subject to 10.1 and 10.2, we are not liable for:
10.4 — The cap. Subject to 10.1 and 10.2, our total liability to you for everything arising out of or in connection with these terms is limited to the greater of the amount you have paid us in the twelve months before the claim and £100. Nothing is charged today, which means the £100 is the figure that currently matters, and we would rather say that than pretend otherwise.
You can end it at any time. Stop using glyso, or delete your account and everything in it from Settings → Account. You do not have to tell us why.
We may end it too. We may suspend or close an account that is breaking these terms, that is being used to attack or abuse the service, or where we are required to. Where it is reasonable to, we will tell you first and give you a chance to export your data. Where the reason is serious — an attack, a legal requirement — we may act immediately.
We may also withdraw the service from everyone, under section 9. If we do, we will give reasonable notice and a way to export first.
What survives the end of this agreement, however it ends: section 6’s licence over de-identified records and aggregated outputs (but not over your content, which is deleted); section 7 (what is ours); section 10 (liability); section 13 (governing law); and anything else which by its nature is meant to continue. Everything else stops.
We may update these terms. If a change matters — anything affecting your rights, your data, or what you pay — we will tell you in the app before or when it takes effect, not by only changing the date at the top.
If you carry on using glyso after a change takes effect, you accept it. If you do not want to, you can stop and delete your account, and if the change is one that disadvantages you materially you can do that without losing anything you have paid for.
glyso is established in London, United Kingdom.
These terms, and any dispute or claim arising out of them or their subject matter — including non-contractual ones — are governed by the law of England and Wales. The courts of London have exclusive jurisdiction, subject to the paragraph immediately below.
If you are a consumer, this does not take away your local rights. You keep the protection of the mandatory consumer law of the country you live in, and if you live in Scotland, Northern Ireland, or another country whose law lets you bring proceedings there, you can. We will bring any claim against a consumer only in the courts of the country you live in.
Third parties. Nobody other than you and glyso has any right to enforce these terms under the Contracts (Rights of Third Parties) Act 1999.
Severability. If a part of these terms turns out to be unenforceable, it is removed and the rest still stands.
No waiver. If we do not enforce something straight away, we have not given it up.
Entire agreement. These terms and the privacy policy are the whole agreement between us about glyso, and they replace anything said before.
We may transfer our rights and obligations under these terms to someone else — for example if the business is sold or reorganised. If we do, your rights under these terms are not reduced, and the privacy policy’s section on a change of business ownership applies to your data. You may not transfer your account or your rights under these terms to anyone else.
