Terms of use
Last updated: 21 October 2026
1. Scope
These terms of use apply to the Logify iOS app and this website. Apple handles the purchase of the app through the App Store; Apple's terms also apply, in particular the Apple Media Services Terms and the Licensed Application End User License Agreement (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
2. Services
Logify is a food diary. You can record and analyse meals, nutrition, symptoms, fasting periods, water and weight. The available features are described on the App Store. With the one-time purchase you receive a right to use the app with no time limit; there is no subscription.
3. Not a medical device
Logify is not a medical device. The app is not intended to detect, monitor, treat or prevent any disease and does not replace a medical diagnosis, advice or treatment.
The "Possible Intolerances" analysis only shows connections in your own entries. It makes no statement about whether a food causes a symptom. If symptoms persist or are severe, please see a doctor. Calorie goals and fasting plans do not replace medical or dietary advice, for example during pregnancy, with eating disorders or pre-existing conditions.
4. Nutrition values and AI estimates
Nutrition values from databases (BLS, USDA, Open Food Facts) and AI estimates in particular are approximations and may differ from actual values. Please check important information yourself. We give no warranty for the accuracy of data from external databases or of AI estimates.
5. Your own API key
If you add your own API key from an AI provider (Google, Anthropic or OpenAI), you enter into the contract with that provider yourself. Its terms and prices apply; any costs are billed to you directly by the provider. You are responsible for keeping your key secret.
6. Your data
Your entries are stored on your device and – if enabled – in your private iCloud. We have no access to them and therefore cannot restore them. Use the export in Settings to create a backup if needed. Details are in the privacy policy.
7. Liability
We are liable without limitation for intent and gross negligence, for injury to life, body or health and under the German Product Liability Act. In cases of slight negligence, we are only liable for breaches of an essential contractual obligation – one whose fulfilment makes proper use of the app possible in the first place and on whose observance you may regularly rely – and limited to the foreseeable damage typical for this type of contract. Otherwise, liability is excluded.
8. Changes and availability
We keep developing Logify and may change, add or – for example if an external service is discontinued – remove features. Features that depend on third-party services (e.g. Apple Intelligence, AI providers, Open Food Facts, iCloud) are only available as long as those services are offered.
9. Final provisions
The law of the Federal Republic of Germany applies. Mandatory consumer protection provisions of the country in which you have your habitual residence remain unaffected. Should any provision be invalid, the validity of the remaining provisions remains unaffected.
