The terms that apply when you use the Gravitas8 app and its membership.
These terms set out the agreement between you and Digital Intelligence Holdings Ltd for the use of the Gravitas8 mobile application and any related services we provide (the "Service"). By creating an account or using the Service you confirm that you accept these terms.
These terms should be read alongside our Privacy Policy and the Disclaimer that appears in-app when you create your account.
Digital Intelligence Holdings Ltd is a company registered in England and Wales with company number 17110569 and registered office at Crown House, 94 Armley Road, Leeds, LS12 2EJ, United Kingdom. References in these terms to "we", "us" and "Gravitas8" mean Digital Intelligence Holdings Ltd.
You must be 18 or over to create an account.
You must provide accurate information when creating your account and you must keep your sign-in credentials confidential.
You are responsible for activity that takes place under your account. If you suspect unauthorised access, please change your password immediately and contact us at support@gravitas8.com.
You may close your account at any time using the Delete my account flow in the app.
Gravitas8 is a general nutrition and lifestyle support tool. The information, coaching, meal plans, nudges and any other content we provide is not medical advice and must not be relied on as a substitute for advice from a qualified clinician.
You must always speak to your GP, midwife, diabetes nurse or other relevant clinician before making decisions about your medical care, including before changing any medication regime, before starting or stopping any specific diet, and during pregnancy or breastfeeding.
In a medical emergency, contact 999 in the UK, 112 in the EU, or your local emergency number. Gravitas8 is not designed to handle emergencies and the AI coach must not be used as a crisis service.
Some features of Gravitas8 are available only with a paid membership. New accounts receive a free trial period, which starts when you create your account and needs no payment details. The length of the trial is shown in the app. When the trial ends you will not be charged unless you choose to subscribe.
If you subscribe, payment is taken by your App Store or Google Play account when you confirm the purchase. Your membership renews automatically at the same price and for the same period (monthly or yearly) unless you cancel at least 24 hours before the end of the current period. Your account will be charged for renewal within the 24 hours before the current period ends. You can manage or cancel your membership at any time in your App Store or Google Play account settings; cancelling stops the next renewal and you keep access until the end of the period you have paid for.
All subscriptions are billed through Apple's App Store or Google's Play Store and are subject to the platform's terms. We use RevenueCat to manage subscription status. You can view your active subscription, switch tier, or cancel through the relevant store's subscription settings.
Refunds are handled in line with the platform's refund policy. Apple's policy is at https://support.apple.com/HT204084. Google's policy is at https://support.google.com/googleplay/answer/2479637. We can request a refund on your behalf in exceptional circumstances; contact us at support@gravitas8.com.
You may not use the Service to engage in any activity that is illegal, that infringes any third party's rights, or that endangers the safety of yourself or others.
You may not attempt to access, probe, scrape or interfere with our infrastructure beyond the documented public API. You may not attempt to reverse-engineer the AI prompts or extract them from coaching conversations.
You may not upload content that is harmful, defamatory, obscene, or that infringes copyright. The community Pods feature in particular requires that you treat fellow members with respect.
You retain all rights to the information you provide to the Service (your meal log, your weight history, your dossier notes, your photos and so on). We use that information only as described in the Privacy Policy.
When you post to a Pod or to the Wins feed, you grant us and other members a non-exclusive licence to display that content within the relevant community surface for as long as your account remains active. You can delete any post you make.
The Gravitas8 app, the API, the coaching personas, the prompts, the brand and the underlying code are owned by Digital Intelligence Holdings Ltd or its licensors. You receive a limited, non-exclusive, non-transferable licence to use the app for personal, non-commercial purposes during the period of your subscription or free use.
You may not copy, modify, redistribute or create derivative works from any part of the Service without our written permission.
Nutrition information for generic, non-branded foods is derived from McCance and Widdowson's The Composition of Foods Integrated Dataset (CoFID), produced by Public Health England. It contains public sector information licensed under the Open Government Licence v3.0. © Crown copyright.
Branded product information is compiled from publicly available packaging and retailer nutrition data. A portion of our branded product catalogue and our barcode lookups is derived from Open Food Facts, a collaborative, free and open database of food products built by its contributors. This data is made available under the Open Database Licence (ODbL) v1.0 (https://opendatacommons.org/licenses/odbl/1-0/), and its individual contents under the Database Contents Licence (DbCL) v1.0. © Open Food Facts contributors. All nutrition figures are estimates and may differ from the current product label.
If you choose to share read-only access with a carer or family member via the Care feature, you control what is shared and you can revoke access at any time. The carer is bound by these terms when accessing your information.
We aim to keep the Service available at all times but we do not guarantee uninterrupted access. We may temporarily suspend access for maintenance, upgrades or to address security issues.
We may add, change or remove features from time to time. Where a change materially reduces functionality of a paid subscription, we will notify you in-app.
You may terminate this agreement at any time by deleting your account through the in-app flow.
We may suspend or terminate your account if you materially breach these terms, including any breach of the Acceptable Use section, or if we are required to do so by law. Where the breach is capable of remedy, we will give you a reasonable opportunity to remedy it before suspending or terminating.
Nothing in these terms limits or excludes any liability that cannot be limited or excluded by law, including liability for death or personal injury caused by negligence, or for fraud.
Subject to the above, our total liability to you under or in connection with this agreement is limited to the greater of (a) the amount you paid us for the Service in the 12 months preceding the event giving rise to the claim, or (b) one hundred pounds sterling.
We are not liable for any loss or damage arising from your reliance on coaching, meal plans, nudges or any other AI-generated content provided through the Service in place of advice from a qualified clinician.
These terms are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction over any dispute arising from or in connection with these terms.
Before bringing any legal action, we ask that you contact us at support@gravitas8.com so we can try to resolve the issue informally. We aim to respond within five working days.
We may update these terms from time to time. When we make material changes we will notify you in-app and ask you to re-accept. The version number and last-updated date below tell you which version of the terms you are currently looking at.
