Terms of Use
Kivaia – an app by ClayFactor GmbH
Effective: June 2026
1. What Is This About?
These Terms of Use govern how you may use Kivaia. Please read them carefully before using the App.
In short:
- Use the App responsibly for your personal lifestyle
- The App is a lifestyle app and does not replace a doctor
- We protect your data (see Privacy Policy)
2. Who May Use the App?
2.1 Minimum Age
Kivaia is intended for persons aged 16 and over. This corresponds to the GDPR standard for independent consent in Germany.
Kivaia's App Store age rating is deliberately set to 16+. This means the legal consent threshold and technical access through the App Store age rating, Screen Time, and Family Sharing refer to the same age threshold.
We deliberately do not run our own age check. By using the app, you confirm that you are at least 16 years old. If we receive concrete indications that a person under 16 is using the app, we block access and delete the associated data.
2.2 Account and Trial
Sign in with Apple is not required to use Kivaia. The trial is managed server-side through an Apple-signed App Store transaction identifier so repeated trial starts after reinstallation can be prevented. You may optionally use Sign in with Apple to prefill profile data. If you sign in optionally:
- Apple authenticates your Apple ID, e.g. with two-factor protection
- We verify only the Apple identity token, app audience, and nonce on the server
- We do not store your email address, name, or plain Apple ID
If the trial server is temporarily unavailable, you can continue using the app in the free state. A trial is created only after successful server-side confirmation.
You can delete your Kivaia account in the app under Settings → “Privacy & Data” → “Delete Account”. This deletes active account/trial bindings and local Kivaia product data; for Sign in with Apple, the Apple authorization is revoked on the server. Account deletion does not start a new free trial. To enforce the one-trial rule, only a minimal proof that is not an account is retained, as described in the Privacy Policy.
3. What May You Use the App For?
3.1 Permitted Use
The App is intended exclusively for your personal, non-commercial use:

4. Important Notice: No Medical Advice
4.1 General Disclaimer
Kivaia is a lifestyle app, not a medical application.
The App provides general information on nutrition, activity, and well-being. It is not a substitute for:
- Professional medical advice
- Diagnoses by qualified professionals
- Medical treatments
- Emergency care
4.2 What This Means
- AI Companion: The AI assistant provides general tips, not medical diagnoses
- Nutritional Analysis: The automatic analysis of meal photos is an estimate, not an exact measurement
- Longevity Score: Your score is a general wellness indicator, not a medical diagnosis
- Activity Recommendations: Adapt all exercises to your physical abilities
4.3 When to Consult a Doctor
Always consult a doctor:
- Before starting a new training or nutrition programme
- For pre-existing health conditions
- If you take medication
- During pregnancy or breastfeeding
- For symptoms or health concerns
In case of medical emergencies, immediately call your local emergency services (112 in the EU, 911 in the US).
4.4 Notice under EU AI Act (Art. 50)
Kivaia uses AI systems from Google (Gemini). You interact directly with an AI in the following features:
- Companion chat: You are chatting with an AI assistant, not a real person.
- Voice coaching (Premium): Spoken responses are based on AI-generated text combined with local text-to-speech on your device.
- Meal analysis: Detection of foods in photos and estimation of nutritional values are fully algorithmic.
- Recipe and daily suggestions: AI-generated based on your input.
AI outputs are estimates and may be inaccurate. They do not replace professional advice. See the Privacy Policy for details on data processing.
5. Intellectual Property
5.1 Our Rights
The App, including all texts, graphics, logos, icons, images, software, and content, is protected by copyright. All rights belong to ClayFactor GmbH or our licensors.
You receive a limited, non-exclusive, non-transferable right to use the App for personal purposes.
5.2 Your Content
You retain all rights to content you create in the App (e.g. meal photos, notes, training entries). This content remains on your device by default.
Where required to provide a feature (e.g. AI analysis of a meal photo), you grant us a purpose-bound, technically required usage licence for the duration of the processing. Details are governed by the Privacy Policy.
