Fit Check terms of use
Effective October 19, 2026
Agreeing to these terms
These terms are an agreement between you and Fit Check ("we", "us") about the Fit Check website and iPhone app. By creating an account or using the app you agree to them and to our privacy policy. If you do not agree, please do not use the app. You must be at least 18 years old to use Fit Check.
What Fit Check is
Fit Check helps you log meals, water, supplements, workouts and mindfulness practice, and see what you logged. You can log by tapping, typing, talking or scanning a photo. We may change, add or remove features over time.
Not medical advice
Fit Check shows you what you logged. Calorie, protein and other figures are estimates, including those read from your words, voice or photos by AI. For a few named branded products we use figures published by the maker; those can change when a product is reformulated, so the package in your hand is always the authority. It does not give medical, dietitian, mental-health or training advice, and the Mind tab is a practice log only. Talk to a doctor before changing your diet, supplements or exercise, especially if you have a health condition. Exercise carries risk of injury; you do it at your own risk. If you think you have a medical emergency, call your local emergency number.
AI features
Chat, voice, spoken replies and photo scanning use AI services run by other companies (see the privacy policy). AI can be wrong or misunderstand you. Always check a proposed entry before you tap Log it or say "log it". You can turn AI off in Account.
Your account and your data
- Keep your sign-in details private. You are responsible for activity on your account and for what you log.
- You own your data. You give us permission to store and process it only to run the app for you, as described in the privacy policy.
- You can download or delete your data in the app under Menu, then Account. Deleting your account is permanent.
Premium subscription
- Fit Check Premium is $7.99 a month (the price can differ by country and is shown by Apple before you buy). New accounts get a 7-day free trial. Tap logging stays free.
- Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically each month unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the period.
- Manage or cancel any time in your Apple ID settings, under Subscriptions. Deleting the app or your Fit Check account does not cancel a subscription.
- Any unused part of a free trial ends when you buy a subscription.
- Refunds are handled by Apple under its policies.
Acceptable use
Do not misuse the app. That means no attempts to break it, probe or bypass its security, access other people's data or accounts, overload it, copy or resell it, or use it for anything unlawful. We may suspend or close accounts that do, and you may stop using Fit Check at any time.
Our content
The app, its design, text, pictures and code belong to us or our licensors. We give you a personal, limited, non-transferable right to use the app on your own devices for your own personal use. All other rights are reserved.
Other companies
The app relies on services from Apple, RevenueCat, Anthropic, OpenAI and Railway. We are not responsible for outages or changes at those companies. These terms are between you and us only. Apple is not a party to them and has no obligation to provide support or maintenance for the app, to handle claims about it, or to refund anything except as Apple's own policies say. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.
Availability and liability
We work to keep Fit Check running, but we provide it "as is" and "as available", with no promise it will always be available, accurate or error-free. To the extent the law allows, we are not liable for indirect, incidental or consequential losses, or for lost data or profits, from using the app, and our total liability for any claim is limited to the amount you paid us in the 12 months before it. Nothing here limits rights you have by law that cannot be limited.
Governing law
These terms are governed by the laws of the State of California, USA, without regard to conflict-of-law rules, and disputes will be handled in the courts located in Los Angeles County, California, unless the law where you live gives you the right to use your local courts.
Changes and ending
If these terms change in a way that matters, we will update the date above and, for significant changes, tell you in the app. Continuing to use Fit Check after a change means you accept it. We may end the service or your access; if we end the service for everyone we will give notice and let you download your data first.
