Terms of Service

Last updated: 25 September 2026

1. Agreement

These Terms of Service (“Terms”) govern your use of the Maika mobile app for iOS and Android (the “App”), provided by Maika GmbH, c/o Anna Karcher, Am Furtbach 4, 8106 Adlikon b. Regensdorf, Switzerland (UID CHE-313.173.143) (“Maika”, “we”, “us”). By creating an account or using the App you agree to these Terms. If you do not agree, please do not use the App.

Our Privacy Policy explains how we handle your personal data. Processing your face and voice recordings and the health estimates derived from them needs your separate, explicit consent, which the App asks for before your first scan. Accepting these Terms does not give that consent.

2. Not medical advice

Maika estimates how relaxed or activated you are to personalise music. Its readings, including heart rate, heart rate variability, arousal and mood estimates, are for general wellbeing only. They are not medical advice, a diagnosis or a treatment, and they may be inaccurate. Do not use the App to make medical decisions or in place of a healthcare professional. If you have a health concern, contact a doctor. In an emergency, call your local emergency number.

3. Who can use the App

You must be at least 16 years old. If you are under the age of majority where you live, a parent or legal guardian must review and agree to these Terms for you. You may only use the App for yourself. Do not scan or record anyone else.

4. Beta version

The App is currently a pre-release (beta) version made available for testing. Features may change, be removed or not work as expected, data may be lost, and we may end the beta at any time. If you send us feedback or suggestions, we may use them to improve Maika without any obligation to you.

5. Your account

• Give accurate information and keep your sign-in details secure. You are responsible for activity on your account.
• Tell us promptly at info@maika-ai.com if you think your account has been misused.
• You can delete your account at any time in Profile → Delete Account.

6. Acceptable use

You agree not to:

• use the App unlawfully, or to harm, harass or deceive anyone;
• record or scan another person;
• copy, modify, reverse engineer or decompile the App, except where the law allows it;
• interfere with, overload or try to gain unauthorised access to the App, our servers or other users’ data;
• download, copy, redistribute or publicly perform the music in the App, or use it outside the App.

7. Your data

You keep your rights in the data you provide. You allow us to process it only as needed to run and improve the App, as described in our Privacy Policy. Face and voice recordings are discarded right after processing.

8. Our rights

The App, its software, design, content and music are owned by Maika or its licensors. We give you a personal, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control, for your own non-commercial use, in line with these Terms and the rules of the app store you downloaded it from.

9. Third-party services

Signing in with Google, Apple or Facebook, and downloading the App from an app store, are subject to those providers’ own terms. We are not responsible for third-party services.

10. Suspension and ending

You can stop using the App and delete your account at any time. We may suspend or close an account that breaks these Terms or puts others at risk, and we may change, pause or discontinue the App. Where reasonable, we will tell you first.

11. Disclaimers

To the extent permitted by law, the App is provided “as is” and “as available”, without warranties of any kind, including that it will be accurate, uninterrupted or error-free. Nothing in these Terms affects rights you have as a consumer that cannot be limited by contract.

12. Limitation of liability

To the extent permitted by law, Maika is not liable for indirect or consequential losses, or for loss of data or profits, arising from your use of the App. Our total liability to you is limited to the amount you paid us for the App in the 12 months before the claim (during the free beta, this is zero). We do not exclude or limit liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot be excluded or limited by law.

13. Changes to these Terms

We may update these Terms. We will change the date at the top and, for significant changes, ask you to accept the new version in the App before you continue using it.

14. Governing law

These Terms are governed by Swiss law, and disputes go to the competent courts at Maika GmbH’s registered office in Regensdorf, Switzerland. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live and may bring claims there.

15. Apple App Store

If you downloaded the App from the Apple App Store: these Terms are between you and Maika, not Apple, and Maika (not Apple) is responsible for the App, its maintenance and support, and any claims relating to it, including product liability, legal or regulatory compliance and intellectual property claims. If the App fails to meet an applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any. Apple has no other warranty obligation for the App. You confirm you are not in a country subject to a U.S. Government embargo and are not on any U.S. Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
