Terms of Service for RedCalendar

(Effective December 22, 2020)

Introduction and summary

Welcome and thank you for your interest in RedCalendar. Our Terms of Service Agreement ("Terms"), along with our Privacy Policy, governs the terms of the relationship between you (and your spouse or partner if you opt him or her into receiving any RedCalendar content) and RedCalendar. You accept these Terms when you Service our applications, products, website, content, communications and services (collectively, the "Services").

The RedCalendar Services provide people with information and insights about menstrual and reproductive health. RedCalendar is intended to be used as an application on mobile devices. By tracking the cyclic changes in your body, you can detect patterns, improve your wellbeing, and notice when things are not "normal" for you. We are always developing new features for different life stages that allow you to understand your body better.

Notwithstanding the requirement for a valid consent to processing your personal data under our Privacy Policy, you must be at least 13 years old (minimum age) to use RedCalendar’s Paid Services. If a minor between the ages of 13 and 17 (a person reaches majority at 18 under German law) uses RedCalendar’s Paid Services, we provide the services on the basis of the deemed consent of their parent or legal guardian, both to these Terms and to the use of the RedCalendar App. Such consent is obtained when an account is created prior to first use of the app. The parent or guardian takes full responsibility for the minor’s use of RedCalendar’s paid services.


By using the App, Service or other services provided by us, you acknowledge that you have read these Terms of Service and agree to be bound by them. IF YOU DO NOT AGREE TO THESE TERMS, YOU MAY NOT ACCESS OR USE THE APP.


The RedCalendar Services are not intended to provide medical advice. For medical advice that addresses your specific, individual needs, please always consult a qualified healthcare professional.

RedCalendar is no substitute for a consultation with your healthcare provider, and the use of the RedCalendar Services is at your own risk. Specific medical conditions can only be diagnosed and treated properly by a qualified healthcare professional. If you feel that the use of the RedCalendar Services causes you any physical or mental distress, please stop using them and seek medical help. We cannot give you medical advice, but if you have any complaint, comment or feedback on the RedCalendar Services, you can reach out to us by email support@calendar.red.


All of the content that we make available within the RedCalendar App is subject to international copyright law unless otherwise indicated. The reproduction, processing, distribution and any form of commercial exploitation of the content, services and software requires our written consent.

We grant you a personal, worldwide, revocable, non-transferable and non-exclusive license to access and use the App for personal and non-commercial purposes in accordance with the terms of this Agreement. You are not entitled to decompile, change or edit the App beyond the extent permissible by law. You are not permitted to lease, rent or otherwise transfer the app and/or its contents.


The content that we provide in the RedCalendar has been compiled with the greatest care. However, we cannot accept any liability for the accuracy, completeness and currency of the content. We are also in no way responsible or liable for the content you track or otherwise provide in the RedCalendar App ("user content"). You are solely responsible for the security of your personal user content. Except to the extent required by law, we accept no liability for the deletion, damage or failure to store user content maintained or transmitted through the use of the RedCalendar Services.

When you use the RedCalendar Services, you do so expressly at your own risk. We give no guarantee that any of our services can be used to achieve a specific aim, such as that events in your individual menstrual cycle will be correctly predicted, or that RedCalendar’s outputs are complete and accurate.

We expressly point out that any health-related recommendations provided in the context of the RedCalendar Services are general in nature, and aimed at users who are generally healthy and physically and mentally fit. If you choose to follow any such general recommendations, you do so at your own risk. If you have any doubt as to whether this is appropriate for you, please speak to your qualified healthcare provider.

Suspension and Termination

We have the right to cancel our service at any time in our discretion for any reason or for no reason. Without limiting the generality of the foregoing, you specifically acknowledge that RedCalendar has the right to terminate or suspend your account in the event that we determine, at our sole discretion, that you have violated these Terms, including participating in any activities that adversely affect other users’ experiences.

Your feedback

We welcome your feedback about the App. Unless otherwise expressly declared, any communications you send to us or publish in app stores are deemed to be submitted on a non-confidential basis. You agree that we may decide to publicize such contents at our own discretion. You agree to authorize us to make use of such contents for free, and revise, modify, adjust and change contextually, or make any other changes as we deem appropriate.


We endeavor to ensure that the RedCalendar App operates without disruption and is available to the greatest extent possible, but we point out that complete and uninterrupted availability is not technically feasible. We therefore do not guarantee disruption-free operation or a specific level of availability. In particular, we may restrict access without providing reasons — in whole or in part, temporarily or permanently. In addition, no claims shall exist regarding the maintenance of individual functionalities of the RedCalendar App. We are entitled at any time to change or remove content, services and functionalities that are provided within the app and to make new content, services and functionalities available or to discontinue the RedCalendar App entirely. This includes paywalling all or certain services that were previously free of charge, as well as their partial or complete discontinuation.

RedCalendar is used by people around the world, who access the app in a multitude of different languages. We use professional translators and proofreaders to translate all of our communications, including these Terms, as accurately as possible into those languages. However, please understand that we cannot assure 100% accuracy for all of our translations, in particular with respect to any legal content. Please note that the English version of these Terms is therefore the original version, which prevails over all other versions in the event of deviation from the English original. The most up-to-date version of these terms is always available in English on our website.

Modification of these Terms

RedCalendar reserves the right, at our sole discretion, to change, modify, add, or remove portions of these Terms at any time with or without specific notice to you other than through posting such modified Terms on our website, through our applications, or both. The Terms will include the most recent date of revision and will be effective immediately upon posting unless otherwise specified herein. If we make any changes to these Terms that we consider to be material to your consent, we will notify you of them. You hereby acknowledge and agree that you will review these Terms periodically for any changes and review the date of last revision at the beginning of the Terms. If you are dissatisfied with the Services, then you agree that your sole and exclusive remedy is to discontinue any use of the Services.
