Terms of service
Last updated: 18 October 2026
About carbs.
carbs. is a free marathon carb-loading planner and food diary, operated by Stuart Wilkinson. Contact carbsdotrun@gmail.com with questions about these terms. These terms apply to your use of carbs.run. Please read them alongside our Privacy policy and Health disclaimer.
What the app provides
The app estimates carbohydrate targets from the details you enter, suggests meals and portions, and helps you record food and drinks. It is intended for adults preparing for endurance events. It provides general information, not medical advice or a personalised clinical nutrition service. No account or payment is currently required.
Using it responsibly
Enter accurate information and check dates, units, portions and product labels. Use the app lawfully. Do not interfere with its operation, attempt unauthorised access, or use it to distribute harmful content. You may use the app for your own planning and diary; rights in its original design, code and content remain with their respective owners.
Estimates and outside information
Targets, meal examples, food estimates and barcode results may be incomplete or wrong. Brands, recipes and serving sizes vary. Barcode information comes from Open Food Facts and is not verified by carbs. Always check packaging, including ingredients and allergens. External services and linked websites have their own terms and may be unavailable.
Your data and backups
Your profile, plans, food diary, notes and saved products are stored in your browser on your device. They do not automatically sync to another browser or device. Clearing browser storage, private browsing, device loss or software problems can remove them. Export a backup from Profile and keep it somewhere safe. We cannot recover data that exists only on your device.
Availability and changes
carbs. is currently in beta. Features may change, and the service may be interrupted, updated or withdrawn. We do not promise uninterrupted availability, error-free calculations, a particular race result, or continued support for every device. Material changes to these terms will be reflected in the updated date on this page. New terms apply to subsequent use and do not remove rights you already have.
Responsibility and your rights
Use the app with appropriate care and seek professional advice where needed. To the extent permitted by law, we are not responsible for losses caused by inaccurate information you enter, third-party services, or a failure to keep a backup. Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any liability that cannot lawfully be excluded. Your statutory consumer rights are unaffected.
Applicable law
These terms are governed by the law of England and Wales, subject to any mandatory protections provided by the law where you live. Nothing here prevents you from bringing a claim in a court available to you under applicable consumer law.
