Terms of Use

Last updated 20 September 2026 · Applies to the Keto Cal iPhone app and ketocalapp.com

1. The agreement

These Terms of Use (“Terms”) are a contract between you and Keto Cal (“Keto Cal”, “we”, “us”), the provider of the Keto Cal iPhone app and ketocalapp.com (together, the “Service”). By downloading, installing or using the Service you agree to these Terms. If you do not agree, do not use the Service.

Our Privacy Policy forms part of these Terms.

2. Who may use Keto Cal

You must be at least 16 years old to use the Service, and old enough to enter a binding contract where you live. Keto Cal is intended for healthy adults making their own dietary choices. It is not intended for, and you should not use it without medical supervision if you: are pregnant or breastfeeding; have type 1 diabetes, type 2 diabetes managed with insulin or sulfonylureas, kidney disease, liver disease, pancreatitis, a gallbladder condition or a disorder of fat metabolism; have or are recovering from an eating disorder; or are under 18.

3. Your licence

We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use the app on Apple-branded devices you own or control, for your own non-commercial use, in accordance with Apple's App Store Terms of Service and these Terms. We reserve all rights not expressly granted.

4. Health and medical disclaimer

Keto Cal is a food-logging and educational tool. It is not a medical device. It does not diagnose, treat, cure or prevent any disease, and nothing in the Service is medical, nutritional, or professional advice.

The “ketosis estimate” is an inference drawn from what you have logged — typically, staying under your chosen net-carb line for three days. It does not measure ketones. Only a blood, breath or urine ketone test measures ketosis. Do not treat the estimate as a clinical result.

Calorie and macronutrient targets produced by the onboarding quiz are generic calculations (Mifflin-St Jeor, adjusted for activity and goal) and are not personalised to your medical history. Projected weight timelines are illustrations, not promises; weight-loss results vary and depend on factors outside the app's knowledge or control.

Always seek the advice of your physician or another qualified health provider with any question about a medical condition or dietary change. Never disregard professional medical advice, or delay seeking it, because of something you read or saw in Keto Cal. If you think you may have a medical emergency, call your doctor or emergency services immediately.

5. Accuracy of estimates

Nutrition values in Keto Cal are estimates and can be inaccurate. This applies to every source the app uses:

• AI photo and text analysis identifies foods and guesses portion sizes from an image or a sentence. It cannot weigh your plate, read your recipe, or know how a dish was prepared. Hidden-carb warnings are heuristics, not measurements.
• Barcode data comes from Open Food Facts, a public database contributed to by volunteers. Entries may be incomplete, outdated or incorrect, and products are reformulated without notice.
• Keto Grades are our own opinionated scoring of a product's suitability for a ketogenic diet, per serving. They are a guide, not a nutritional authority, and reasonable people may score differently.
• Built-in food data uses reference values that vary naturally between brands, growing conditions and preparation methods.

Where accuracy matters — to you, or to your health — check the product's packaging and consult a professional. You are responsible for reviewing and correcting what the app logs; every value in the app is editable for exactly this reason.

6. Subscriptions and free trial

Keto Cal offers auto-renewing subscriptions purchased through the App Store:

• Yearly — $34.99 per year
• Weekly — $4.99 per week

Prices are in US dollars and may differ in your local currency and with tax. We may change prices for future periods; where required, you will be told in advance and an increase will not take effect until you accept it or your next renewal after notice, per Apple's rules. A discounted offer may be presented at our discretion and is not a permanent price.

Both plans may include a 3-day free trial for new subscribers. Key points:

• Payment is charged to your Apple ID when the trial ends, unless you cancel first.
• Your subscription renews automatically at the then-current price unless you cancel at least 24 hours before the end of the current period.
• Cancel in Settings › [your name] › Subscriptions on your iPhone. Deleting the app does not cancel a subscription.
• If you cancel during a trial, access continues until the trial ends.
• Free-trial eligibility is determined by Apple, generally once per Apple ID per subscription group.

Apple is the merchant of record. Billing, renewals and cancellations are handled by Apple under your App Store account terms.

7. The free tier

Without a subscription you can still use Keto Cal with limits, currently: three AI photo scans in total, unlimited manual logging, and the net-carb ring. We may change what the free tier includes at any time. The free tier is offered as-is and may be withdrawn or altered without notice.

8. Refunds

Purchases are made through Apple, so all refunds are handled by Apple under its policies — we cannot issue, approve or reverse a charge. Request a refund at reportaproblem.apple.com. Nothing here limits statutory rights you may have as a consumer, including any right to withdraw from a purchase under local law.

9. Acceptable use

You agree not to: reverse-engineer, decompile or attempt to extract the source code of the app except to the extent the law expressly permits; access our analysis service other than through the app, or use it to build a competing product, resell its output, or process images unrelated to food; circumvent rate limits or paywalls; submit unlawful, infringing or abusive content; use automated systems to access the Service at volume; or interfere with the Service's operation or security. We may rate-limit, suspend or block access that breaches this section.

10. Your content

You keep ownership of everything you put into Keto Cal — your photos, entries, custom foods and notes. That content is stored on your device, not by us. You grant us a limited licence to process a photo or description you submit for analysis solely to return a nutrition estimate to you, and for no other purpose. That licence ends when the request completes. You confirm you have the right to submit any image you send.

11. Our intellectual property

The Service, including the app, its design, the Keto Grade scoring system, our curated food data, text, graphics, the Keto Cal name and logo, and this website, is owned by us and protected by copyright, trademark and other laws. You may not copy, modify, distribute, sell or lease any part of it, or create derivative works from it, except as these Terms allow.

12. Third-party services

Keto Cal relies on services we do not control, including Apple (distribution, billing, HealthKit), RevenueCat (subscription management), Anthropic (AI analysis) and Open Food Facts (barcode data). Their availability, accuracy and terms are their own. We are not responsible for their acts or omissions, and a failure or change in any of them may affect features of the app.

13. Availability and changes

We aim to keep the Service running but do not guarantee it will be uninterrupted, timely, secure or error-free. We may add, change, suspend or remove features, and may discontinue the Service, at any time. If we discontinue a paid subscription service entirely, we will not charge you for periods after it ends.

14. Disclaimer of warranties

To the fullest extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, whether express, implied or statutory, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service will meet your requirements, that its estimates will be accurate, or that defects will be corrected. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.

15. Limitation of liability

To the fullest extent permitted by law, neither we nor our suppliers will be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for lost profits, lost data, or loss of goodwill, arising out of or relating to your use of or inability to use the Service, or reliance on any estimate, grade or figure it produces — even if we have been advised of the possibility.

To the fullest extent permitted by law, our total aggregate liability arising out of or relating to the Service is limited to the greater of (a) the amount you paid us for the Service in the twelve months before the claim, or (b) US$50.

Nothing in these Terms limits or excludes liability that cannot lawfully be limited or excluded, including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or any non-excludable consumer rights you have under the law of your country of residence.

16. Indemnity

You agree to indemnify and hold us harmless from claims, damages, losses and reasonable legal costs arising from your breach of these Terms, your misuse of the Service, or content you submit through it.

17. Termination

You may stop using the Service at any time by deleting the app — remember to cancel any subscription separately through Apple. We may suspend or terminate your access if you materially breach these Terms, or where required by law. Sections that by their nature should survive termination — including sections 4, 5, 10, 11, 14, 15, 16 and 20 — will survive.

18. Apple-specific terms

These Terms are between you and us only, not with Apple, and Apple is not responsible for the app or its content. The following apply because the app is distributed through the App Store:

• Apple has no obligation to furnish any maintenance or support for the app.
• In the event the app fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app.
• Apple is not responsible for addressing any claim by you or a third party relating to the app, including product liability claims, any claim that the app fails to conform to a legal or regulatory requirement, and claims arising under consumer protection or similar legislation.
• Apple is not responsible for the investigation, defence, settlement or discharge of any third-party claim that the app infringes intellectual property rights.
• You represent that you are not located in a country subject to a US Government embargo or designated as a “terrorist supporting” country, and that you are not on any US Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, will have the right to enforce them against you.

19. Changes to these terms

We may update these Terms. The “last updated” date above will change, and material changes will be signalled in the app or by a notice on this site. Continuing to use the Service after a change takes effect means you accept the revised Terms. If you do not accept them, stop using the Service and cancel any subscription.

20. Governing law and disputes

These Terms are governed by the laws applicable at our principal place of business, without regard to conflict-of-laws rules, and you and we submit to the courts with jurisdiction there.

If you are a consumer, this does not deprive you of the protection of mandatory consumer-protection laws of your country of residence, and you may be entitled to bring proceedings in your local courts.

Before starting a formal dispute, please email us — most problems are solved faster that way.

21. General

These Terms, together with the Privacy Policy, are the entire agreement between you and us about the Service. If a provision is found unenforceable, the rest stays in force and the provision is applied as closely as possible to its intent. Our failure to enforce a right is not a waiver of it. You may not assign these Terms; we may assign them to a successor in connection with a merger, acquisition or sale of assets.
