Terms of use

1. Introduction

1.1 Services. We have developed various products and services under our Crumbs brand, such as but not limited to, the Crumbs iOS and Android mobile applications (our Crumbs “Products” or “Services”). Our Products provide tracker and malware filtering which allow you to—among other things—disable tracking and block domains known to spread malware. Some of our Crumbs Products may also enable the measurement of ad effectiveness and/or enable relevant ads in an anonymous aggregated way. Additional information on the Products can be found here.

1.2 Terms of Use. These Terms of Use (the “Terms”) apply to your use of the Products. By downloading the Products, you acknowledge that you have read these Terms and agree that you are legally bound by these Terms. If you do not agree to these Terms, do not download the Products and/or uninstall them from your devices.

1.3 Privacy. We collect and process certain personal data to provide secure, efficient, and user-friendly experiences with the Services. For information on how we collect and process your personal data, please read our Privacy Policy.

1.4 eyeo GmbH. For purposes of these Terms, “eyeo”, “we”, “us”, or “our” means eyeo GmbH, Kunibertsgasse 10, 50668 Cologne, Germany, Local Court Cologne HRB 73508, VAT ID: DE279292414, represented by the managing director Till Faida, e-mail address: info@eyeo.com.

1.5 Reservation of Rights. We reserve the right to change these Terms at our sole discretion and will do so by posting any modified Terms on this page. If required by applicable laws, we will inform you in advance of the effective date of any new Terms (i.e., the date at which the new Terms will become effective) which may be by notice on the Crumbs Products or other means we elect. If you do not object to the new Terms, you will be considered to have agreed to be bound by the modified Terms as of the effective date.

2. License

2.1 License Grant. Subject to and conditioned on your compliance with the terms and conditions of these Terms, we grant to you a limited, revocable, non-exclusive, non-sublicensable, non-transferable, and non-assignable license to download, install, and use a copy of the Crumbs Product for your personal, non-commercial use on a compatible device that you own or control solely as expressly authorized and/or required by these Terms.

2.2 Ownership. You acknowledge and agree that a copy of the Crumbs Product is provided under license, and not sold, to you. You do not acquire any title or ownership interest in or to the Crumbs Product, including any copy thereof, or any rights other than your right to use your copy of the Crumbs Product in accordance with the license granted to you in these Terms. Except as expressly granted to you in these Terms, we and our licensors reserve our entire right, title, and interest in and to the Crumbs Product, including all copyrights, trademarks, and other intellectual property rights arising therefrom or related thereto. Further, we reserve all rights not expressly granted or waived in these Terms.

2.3 Feedback. You may, but are not required to, provide us with recommendations, suggestions, comments, ideas, proposals, evaluations, reviews, feedback, input or other information related to the Services (collectively “Feedback”). In the event that you provide us Feedback, you hereby grant us and our affiliates a perpetual, irrevocable, worldwide license to use Feedback in any way for any purpose without reimbursement or compensation and without any obligation to report on such use or other restriction on such use.

3. What should you do if the Products are not working properly?

3.1 Except for any statutory rights for digital products and services to which you may be entitled and which cannot be waived as a matter of law, the Products are provided “as is” and on “as available” basis. You acknowledge and understand, for example, that the Products may not be available during a maintenance or repair window, a power outage, or an internet service interruption.

3.2 You use the Products at your own risk. We do not make any representation or warranty that the Products will meet your requirements or function in an uninterrupted, timely, secure, or error-free manner. Without limiting the generality of the previous statements, we also do not make any representation or warranty that all trackers or malware will be blocked.

3.3 You acknowledge and understand that the filters that are used on the Products may occasionally result in blocked content. This is an unwanted side effect and cannot be completely avoided.

3.4 We encourage you to immediately report any errors or incorrect blocking that you may discover. These reports will help us improve the Products.

4. Liability for Damages

4.1 Except with respect to claims for damages to you arising from injury to life, body, health, or from the violation of essential contractual obligations (so-called cardinal obligations), eyeo will only be liable for damages to the extent that damages are based on an intentional or grossly negligent breach of duty by eyeo, its legal representatives, or its vicarious agents. Essential contractual obligations are those whose fulfillment are necessary to achieve the objective of the contract.

4.2 In the event of a breach of essential contractual obligations, eyeo is only liable for the foreseeable damage typical for the contract if such damage was caused by simple negligence, unless your claims for damages are based on injury to life, body, or health.

4.3 The limitations of liability made in Sections 4.1 and 4.2 above also apply to the legal representatives, employees, and vicarious agents of eyeo if claims are asserted directly against them.

4.4 The limitations of liability made in Sections 4.1 and 4.2 above do not apply if eyeo has assumed a guarantee for the quality of the Services or has fraudulently concealed a defect of the Services. The limitations of liability made in Sections 4.1 and 4.2 above also do not apply if eyeo and you have reached a separate, written agreement on the quality of the Services. The provisions of the German Product Liability Act remain unaffected.

5. Dispute Resolution

The European Commission provides a platform for online dispute resolution (OS). This can be accessed via the following link: https://ec.europa.eu/consumers/odr. eyeo GmbH is neither obliged nor willing to participate in a dispute resolution procedure before a consumer arbitration board.

6. Final Provisions

6.1 The law of the Federal Republic of Germany will govern these Terms to the exclusion of the provisions of the UN Convention on Contracts for the International Sale of Goods. If, however, your habitual residence at the time that you downloaded the Products is located in a jurisdiction which requires the application of its own laws to these Terms, then such laws will govern these Terms.

6.2 At the time that these Terms become effective on each of us (i.e., you and eyeo), there are no verbal ancillary agreements and/or additions. Collateral agreements, amendments, or supplements must be made in writing and signed by an authorized representative of each party to be effective. The waiver of the written form requirement must also be in writing.

6.3 In the event that a circumstance beyond our reasonable control prevents us from providing you the Services in accordance with these Terms (each a “Force Majeure Event”), you acknowledge and agree that we have no obligation under these Terms to the extent and duration of such Force Majeure Event.

6.4 In the event that any provision of these Terms is or becomes invalid, such invalidity will not affect the validity of the remaining provisions.
