What Are Fettle's Terms & Conditions?

Fettle's Terms & Conditions, last updated December 12, 2025, govern how users interact with the Fettle Service — defined as the fettle.fit website, the Fettle iOS and Android application, nutrition calculators, content tools, and all associated features. Operated by Fettle Fitness Limited in London, these Terms establish a binding legal agreement between the Company and every User who accesses or uses the platform. By simply using the Service, users confirm they have read, understood, and accepted these Terms in full, alongside Fettle's Privacy Policy, which forms an integral part of the agreement.

Key Definitions You Need to Know

Fettle uses precise legal definitions to eliminate ambiguity throughout its Terms. The Application refers specifically to the Fettle mobile app on iOS and Android. The Website means https://fettle.fit and any associated domains. The Service is the umbrella term covering everything Fettle provides. The Company — also referred to as We, Us, or Our — is Fettle Fitness Limited, Floor 2, 87–88 Turnmill Street, London, EC1M 5QU. User, You, or Your means any individual accessing the platform. Content covers all text, images, data, recipes, and logs. Third-Party Services include Apple Health, Google Fit, Amazon Fresh, supermarkets, and wearable device providers — none of which are operated by Fettle.

Critical Health Disclaimer: What Fettle Is NOT

Fettle is a nutrition guidance and macro planning tool — not a medical service. This distinction is one of the most important aspects of Fettle's Terms. The platform does not provide medical advice, diagnose medical conditions, treat or prevent disease, or replace qualified healthcare professionals such as GPs, dietitians, or nutritionists. All information delivered through Fettle's tools, calculators, and personalised plans is strictly for general informational and educational purposes. Users with medical conditions, eating disorders, or special dietary needs are explicitly advised to consult a qualified healthcare professional before making any changes to their diet, exercise, or health routines. Any decisions made based on Fettle's outputs are made at the user's own discretion and risk — a transparency standard that aligns with leading health app best practices globally.

Personalised Nutrition Tools and Calculator Features

Fettle's Service includes a robust suite of personalised nutrition features designed to support smart macro planning. These include BMI calculators, TDEE (Total Daily Energy Expenditure) tools, protein calculators, personalised calorie targets, macronutrient breakdowns, meal suggestions and recipes, progress tracking, trend analysis, and automated guidance insights. Importantly, all outputs generated by these tools are estimates based on user-provided data and established nutritional science models. Fettle does not and cannot guarantee specific outcomes, which is consistent with responsible nutrition app disclosure standards across the industry — including competitors like MyFitnessPal, Cronometer, and Noom.

Account Eligibility, Access, and User Responsibilities

To access Fettle's full feature set, users may need to create an account. Eligibility requires users to be at least 18 years old with the legal capacity to enter a binding agreement. Users are responsible for providing accurate, up-to-date information and for maintaining the confidentiality of their account credentials. Fettle Fitness Limited reserves the right to refuse, suspend, or terminate access in cases of misuse, abuse, or breach of these Terms — a standard protective provision common to apps operating under UK consumer protection law and GDPR frameworks.

Pricing, Beta Access, and Future Changes

As of the Terms' effective date of December 12, 2025, Fettle may be offered free of charge during beta or trial periods. However, Fettle Fitness Limited expressly reserves the right to introduce paid subscriptions, implement tiered or feature-gated access models, and adjust pricing, features, or availability going forward. Material changes will be communicated in advance where reasonably possible, giving users fair notice — a practice encouraged by the UK Competition and Markets Authority (CMA) for digital subscription services.

User Content, Conduct, and Intellectual Property

Fettle allows users to submit content including food logs, messages, photos, and recipes. Users retain ownership of their submitted content but grant Fettle Fitness Limited a non-exclusive, royalty-free licence to use, process, and display that content for operating and improving the Service. In return, users agree to acceptable use standards — prohibiting submission of unlawful, harmful, or misleading content, and prohibiting any activity that could compromise the Service's integrity, other users' safety, or Fettle's legal compliance obligations.
