Terms of Service

These Terms of Service ("Terms") govern your access to and use of the Zeitlernen website, the Zeitlernen apps for iOS and Android, the software, the platform, and all related services (collectively, the "Services").

By accessing or using the Services or creating an account, you agree to be legally bound by these Terms and our Privacy Policy.

If you do not agree, you must not use the Services.

These Terms apply worldwide to the maximum extent permitted by applicable law.

To use the Services, you must:

• be at least 18 years old (or the legal age in your jurisdiction)
• have the legal capacity to enter into binding agreements

You must create an account and provide accurate and complete information.

You are solely responsible for:

• maintaining the confidentiality of your login credentials
• all activities under your account
• keeping your information accurate and up to date

We may suspend or terminate accounts at any time, at our sole discretion.

Children may use the services provided they are supervised by a parent or legal guardian, or within an educational institution (e.g. school, teacher). The supervising person is responsible for the child’s use of the services.

You agree to use the Services only in compliance with applicable laws and these Terms.

You may not:

• use the Services for illegal or unauthorized purposes
• attempt to gain unauthorized access to systems or data
• interfere with or disrupt the Services
• use automated tools such as bots or scrapers without permission
• resell or commercially exploit the Services without authorization

The Services are currently provided free of charge. No fees apply for using the Services.

We expressly reserve the right to make the Services, or parts thereof, subject to fees in the future, to introduce new paid features, or to change the pricing model.

In the event that paid features are introduced, you will be notified in advance. Any obligation to pay will only take effect after your explicit consent. An existing account alone does not create any obligation to pay.

The free provision of the Services does not establish any right to continued free use.

All rights in the Services remain with us or our licensors.

We grant you a limited, non-exclusive, non-transferable, revocable license to use the Services for personal use while your account is active.

You may not:

• copy or distribute the Services
• reverse engineer or extract source code
• use the Services to build competing products

The Services are provided "as is" and "as available".

We make no warranties of any kind, whether express or implied, including but not limited to merchantability, fitness for a particular purpose, or non-infringement.

We do not guarantee that:

• the Services will be uninterrupted or error-free
• results will be accurate, complete, or reliable
• the Services will meet your expectations

All use of the Services is at your own risk.

To the maximum extent permitted by law:

We are not liable for any damages arising out of or related to the use of the Services.

This includes, but is not limited to:

• indirect or consequential damages
• loss of profits, revenue, business, or data
• decisions made based on the Services

7.1 Data, Backups, and Recovery

You acknowledge and agree that:

• we do not guarantee data storage or availability
• we do not guarantee backups
• we do not guarantee data recovery in case of loss
• data may be lost, corrupted, or deleted at any time

You are solely responsible for maintaining your own backups.

7.2 Maximum Liability

As the Services are provided free of charge, our total liability is, to the extent permitted by law, limited to CHF 100.

We do not guarantee continuous availability of the Services.

We may modify, suspend, or discontinue the Services at any time without any claims arising therefrom.

You may delete your account at any time. We may suspend or terminate access at any time.

Upon termination or account deletion:

• your right to use the Services ends immediately
• your stored data may be permanently deleted

How to delete your account

The Services may rely on third-party providers.

We are not responsible for:

• third-party services or availability
• data processed by third parties
• damages caused by third-party services

You are responsible for compliance with local laws in your jurisdiction.

We are not liable for delays or failures caused by events beyond our control, including infrastructure failures or third-party outages.

If any provision is invalid, the remaining provisions remain in effect.

We may update these Terms at any time. We will notify you of material changes through appropriate channels.

Continued use of the Services after notification of a change constitutes acceptance of the updated Terms.

These Terms are governed by Swiss law.

Place of jurisdiction is Sursee, Canton of Lucerne, Switzerland, unless mandatory law provides otherwise.

The Zeitlernen apps for iOS and Android are distributed through Apple's App Store and through Google Play. In addition to these Terms, the usage rules of the respective store apply to downloading and using the app.

We grant you a limited, non-transferable licence to use the app on devices that you own or control, subject to the usage rules of the respective store.

16.1 Apple App Store

For apps downloaded from the App Store, the following also applies:

• These Terms are between you and us, not between you and Apple. We alone are responsible for the app and its content.
• Apple has no obligation to provide maintenance or support for the app. Please send support requests to support@zeitlernen.app.
• If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund any purchase price you paid. Beyond that, to the maximum extent permitted by law, Apple has no warranty obligation whatsoever. The app is currently provided free of charge, so no purchase price applies.
• Claims relating to the app are our responsibility and not Apple's, in particular product liability, compliance with legal requirements, and claims under consumer protection law.
• If a third party claims that the app infringes their intellectual property rights, defending such claims is our responsibility and not Apple's.
• You represent that you are not located in a country subject to a US embargo or designated by the US government as supporting terrorism, and that you are not listed on any US list of prohibited or restricted parties.
• Apple and Apple's subsidiaries are third-party beneficiaries of these Terms. By accepting them, you grant Apple the right to enforce these Terms against you.

16.2 Google Play

For apps obtained from Google Play, the Google Play Terms of Service apply in addition. Google is not a party to these Terms and is not responsible for the app.

16.3 In-App Purchases

The apps currently contain neither purchases nor advertising. If we introduce paid features in the future (see section 4), payments inside the apps will be processed by Apple or Google. Billing, refunds and cancellation are then governed by the rules of the respective store.

16.4 App Store Data

Apple and Google only distribute the app package. Which data they collect when you download the app and while operating their stores is their own responsibility; we have no influence over it. Details are set out in our privacy policy.
