It allows you to capture thoughts via text or voice, and uses artificial intelligence to analyze your messages, extract tasks, and help you organize your thinking. The Service includes AI analysis features powered by third-party providers (OpenAI).
3. Account Registration
To use Levin, you must create an account using Apple Sign In, Google Sign In, or email authentication. You are responsible for maintaining the security of your account credentials and for all activity under your account.
You must be at least 16 years old to create an account and use the Service.
4. Acceptable Use
You agree not to:
- Use the Service for any unlawful purpose or in violation of any applicable laws
- Attempt to gain unauthorized access to the Service, other accounts, or our systems
- Interfere with or disrupt the Service or its infrastructure
- Use automated tools to access the Service in a manner that exceeds normal usage patterns
- Upload content that infringes on intellectual property rights of others

5. Your Content
You retain ownership of all content you create in Levin, including thoughts, tasks, topics, and notes. We do not claim any intellectual property rights over your content.
By using the Service, you grant us a limited license to process your content as necessary to provide the Service, including transmitting it to third-party AI services for analysis and transcription as described in our Privacy Policy.
6. AI-Powered Features
Levin uses artificial intelligence to analyze your messages and generate suggestions, task extractions, and organizational insights. You acknowledge that:
- AI analysis results are suggestions only and may not always be accurate or complete
- AI-generated content is not a substitute for professional advice of any kind
- Your content is transmitted to OpenAI for processing as described in our Privacy Policy
- We do not guarantee the availability, accuracy, or reliability of AI features
7. Credit System
The Service includes a credit system that limits the number of AI analysis requests you can make per billing period. Credit allocations and limits may change. We will notify you of any material changes to the credit system through the app.
8. Service Availability
We strive to maintain high availability of the Service, but we do not guarantee uninterrupted access. The Service may be temporarily unavailable due to maintenance, updates, or circumstances beyond our control. AI features depend on third-party services (OpenAI) and may be unavailable if those services experience downtime.
9. Termination
You may delete your account at any time from the Settings screen in the app. Upon deletion, all your data will be permanently removed as described in our Privacy Policy.
We reserve the right to suspend or terminate your account if you violate these Terms, with notice where practicable. In case of termination for cause, we will provide you with reasonable opportunity to export your data unless prohibited by law.
10. Limitation of Liability
To the maximum extent permitted by applicable law, the Service is provided “as is” and “as available.” We make no warranties, express or implied, regarding the Service, including warranties of merchantability, fitness for a particular purpose, or non-infringement.
To the maximum extent permitted by law, Busch & Busch GbR shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Service. This limitation does not apply to liability for intentional misconduct or gross negligence, or where otherwise prohibited by mandatory law.
11. Apple App Store Terms
If you access the Service through the Apple App Store, the following additional terms apply:
- These Terms are between you and Busch & Busch GbR, not with Apple Inc.
- Busch & Busch GbR, not Apple, is solely responsible for the Service and its content
- Apple has no obligation to provide maintenance or support for the Service
- In the event of any failure of the Service to conform to applicable warranties, Apple's sole obligation is to refund the purchase price (if any)
- Apple is not responsible for addressing any claims relating to the Service, including product liability, legal compliance, or intellectual property infringement
- Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you
12. Third-Party Services
The Service integrates with third-party services (Clerk, OpenAI, Expo). Your use of these integrated services is also subject to their respective terms. We are not responsible for the availability or operation of third-party services.
13. Changes to These Terms
We may update these Terms from time to time. If we make material changes, we will notify you through the app or by email at least 30 days before the changes take effect. Your continued use of the Service after the changes take effect constitutes your acceptance of the revised Terms.
14. Governing Law & Dispute Resolution
These Terms are governed by and construed in accordance with the laws of the Federal Republic of Germany, without regard to conflict of law provisions. If you are a consumer within the European Union, you also benefit from mandatory provisions of the consumer protection laws of your country of residence.
The European Commission provides a platform for online dispute resolution (OS): https://ec.europa.eu/consumers/odr. We are not willing or obliged to participate in dispute resolution proceedings before a consumer arbitration board.
