Best Brokers License Agreement

This License Agreement is between you and Best Brokers, and governs your use of the Best Brokers app made available for use on smartphones and other electronic devices.

Best Brokers grants you a limited, non-exclusive, non-transferable and revocable license to use the Best Brokers App for your personal, non-commercial purposes. You may only use the Best Brokers app on a device that you own or control and that is permitted by any applicable usage rules applied by your device’s manufacturer or by the marketplace at which we have made the app available. The terms of this license will also govern any upgrades provided by Best Brokers that replace and/or supplement the original app, unless such upgrade is accompanied by a separate license, in which case the terms of that license will govern.

However, unless we expressly state otherwise, your right to use the Service does not include:

  • using the Best Brokers app on any mobile device that you do not own or control
  • publicly performing or publicly displaying the Service
  • modifying or otherwise making any derivative uses of the Service or any portion thereof

Intellectual Property Rights

The design of the Best Brokers app along with the texts, scripts, graphics, interactive features and the like created by Best Brokers, as well as the trademarks, service marks and logos contained therein are owned by or licensed to Best Brokers, subject to copyright and other intellectual property rights and the German and foreign laws and international conventions. Best Brokers provides the Service to you AS IS for your information and personal use only. Best Brokers reserves all rights not expressly granted in and to the Service. You agree to not engage in the use, copying, or distribution of any of the Service other than expressly permitted herein, including any use, copying, or distribution of posts of your contacts obtained through the Service for any commercial purposes.


The Service and content included on or otherwise made available to you through the Service is provided on an AS IS or AS AVAILABLE basis without any representations or warranties of any kind.

While Best Brokers attempts to provide a good user experience, we cannot and do not represent or warrant that the Services will always be secure or error-free or that the Services will always function without delay, disruptions or imperfections. Best Brokers cannot guarantee that its Services are virus-free. The user shall take all necessary safety measures and install the latest security updates, in order to prevent viruses.

In the event of any failure of the app to conform to any applicable warranty, you may notify the marketplace from which you have downloaded the app.

Any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty will be our sole responsibility.

Limitation of Liability

Best Brokers shall only be liable for willful intent or gross negligence. This limitation of liability does not apply to claims for damages that result from injury to life, body or health.

Best Brokers shall not be liable for slight negligence, if no essential contractual obligation is violated, as far as no guarantee has been agreed upon for the quality of the Services, as far as there is no maliciously concealed defect, default or impossibility for which Best Brokers is responsible. In case of slightly negligent violation of essential contractual duties, the fulfillment of which is required for the due execution of a contract and the observance of which the user relies on and may rely on, the claim for damages shall be limited to the amount of typically predictable damage. The above limitation of liability does not apply to claims for damages that result from injury to life, body or health. The liability according to the German Product Liability Act (Produkthaftungsgesetz) remains unaffected.

As far as the liability of Best Brokers is excluded or limited, the same applies for the personal liability of the employees, representatives and agents of Best Brokers.


You agree to defend, indemnify and hold Best Brokers harmless from and against any and all claims, damages, obligations, losses, liabilities, costs or debt, and expenses (including but not limited to attorney s fees) arising from: (i) your use of and access to the Best Brokers Service; (ii) your violation of any term of these Terms; (iii) your violation of any third party right, including without limitation any copyright, property, or privacy right; or (iv) any claim that one of your posts caused damage to a third party. This defense and indemnification obligation will survive these Terms and your use of the Best Brokers Service.

Change of Service

We may in our sole discretion review, improve, modify or discontinue, temporarily or permanently, the Service and/or any information or content on the Service. If we do so, we will provide notice of such changes, such as by e.g. sending a Push-Notification to you.

You agree that Best Brokers will not be liable to you or any third party for any modification or discontinuance of the Service or any portion thereof.


We may transfer, sub-contract or otherwise deal with our rights and/or obligations under these Terms, without notifying you or obtaining your consent.

Privacy Policy

We provide you with information on how we collect and process our users data in our Privacy Policy.

Governing Law, Side Agreements

These Terms shall be governed by and construed in accordance with German law, and any dispute between you and Best Brokers relating to these Terms will be subject to the exclusive jurisdiction of the courts of Germany.

In case individual provisions in these Terms are or become invalid, or should gaps arise in these Terms, the validity of all other provisions shall not be deemed affected thereby. Instead of the ineffective provision or for replenishment of gaps an adequate provision shall apply, which – to the extent legally permitted – comes as close as possible to what Best Brokers would have wanted in the first place, provided that Best Brokers had thought of the invalid or incomplete provision.

Side agreements require written form. Also, any waiver of the written form shall only be made in writing.
