By downloading or using our Apps, these terms will automatically apply to you – you should make sure therefore that you read them carefully before using the app. You’re not allowed to copy or modify the app, any part of the app, or our trademarks in any way. You’re not allowed to attempt to extract the source code of the app, and you also shouldn’t try to translate the app into other languages or make derivative versions. The app itself, and all the trade marks, copyright and other intellectual property rights related to it, still belong to Manuel Rodríguez Vallejo (“the developer”).
1.1 Please be aware that all our apps have been designed for research and not for medical purposes. They are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease. The information provided by our Apps is not intended to use for the benefit of individual patients, but it is intended to evaluate the results along a sample of patients in order to conduct research. By downloading and using our apps you agree to use them only for research purposes.
2.1 For achieving the previous purpose, the app stores in the device non-personal data using a pseudo-identifier in order to ensure that only the user who introduces the data might identify the subject. The developer does not collect any personal data from you or from the pseudo-anonymized data that you introduce in the app. All the data remain only in your device and can be encryptep by Apple and stored in the iCloud if you conduct an iCloud backup.
2.2 Although the developer has designed the app in order to prevent that you introduce personal data, he cannot take responsibility for you of the kind of number you use to pseudo-identify the subject. It is your responsibility to use a numeric unique pseudo-identifier that does not directly identify the subjects. If you use a re-identification file, it is important to note that this must comply with your local regulations, such as the GDPR in Europe or the HIPAA in the United States. For security reasons, maintain any re-identification file always outside from your device, on which the app is downloaded, or any other device linked to the same iCloud account, or your iCloud account itself.
2.3 It is also your responsibility to have the consent of the subjects for using their data for any purpose in case of being required. The app allows you to export the pseudo-anonymized data stored in the device by email, the developer cannot take responsibility if you do not manage or share the data in an ethic manner or according to your local applicable laws.
3.1 The developer is committed to ensuring that the app is as useful and efficient as possible. For that reason, we reserve the right to make changes to the app or to charge for its services, at any time and for any reason. We will never charge you for the app or its services without making it very clear to you exactly what you’re paying for. The scope of the services may depend on the subscription you have. The developer may change, update, suspend, make improvements to, or discontinue aspects of the services.
3.2 For Apps with PRO subscription the apps can offer an automatically renewable subscription (“PRO”) for a period of time. A subscription enables you to access and use the fill scope of the services for the subscription period. Payment will be charged to your iTunes account upon confirmation of purchase. It is your responsibility to turn-off your subscription at least 24-hours before the end of the current period if you do not want to renew the subscription.
4.1 It’s your responsibility to keep your phone and access to the app secure. We, therefore, recommend that you do not jailbreak or root your phone/tablet, which is the process of removing software restrictions and limitations imposed by the official operating system of your device. It could make your phone vulnerable to malware/viruses/malicious programs, compromise your phone’s security features and it could mean that the app won’t work properly or at all.
4.2 You should be aware that there are certain things that the developer will not take responsibility for. Certain functions of the app will require the app to have an active internet connection. The connection can be Wi-Fi, or provided by your mobile network provider, but the developer cannot take responsibility for the app not working at full functionality if you don’t have access to Wi-Fi, and you don’t have any of your data allowance left.
4.3 If you’re using the app outside of an area with Wi-Fi, you should remember that your terms of the agreement with your mobile network provider will still apply. As a result, you may be charged by your mobile provider for the cost of data for the duration of the connection while accessing the app, or other third party charges. In using the app, you’re accepting responsibility for any such charges, including roaming data charges if you use the app outside of your home territory (i.e. region or country) without turning off data roaming. If you are not the bill payer for the device on which you’re using the app, please be aware that we assume that you have received permission from the bill payer for using the app.
4.4 Along the same lines, the developer cannot always take responsibility for the way you use the app. i.e. You need to make sure that your device stays charged – if it runs out of battery and you can’t turn it on to avail the Service, the developer cannot accept responsibility.
4.5 With respect to the developer’s responsibility for your use of the app, when you’re using the app, it’s important to bear in mind that although we endeavor to ensure that it is updated and correct at all times, we do rely on third parties to provide information to us so that we can make it available to you. The developer accepts no liability for any loss, direct or indirect, you experience as a result of relying wholly on this functionality of the app.
4.6 At some point, we may wish to update the app. The app is currently available on iOS – the requirements for system (and for any additional systems we decide to extend the availability of the app to) may change, and you’ll need to download the updates if you want to keep using the app. The developer does not promise that it will always update the app so that it is relevant to you and/or works with the iOS version that you have installed on your device. However, you promise to always accept updates to the application when offered to you, We may also wish to stop providing the app, and may terminate use of it at any time without giving notice of termination to you. Unless we tell you otherwise, upon any termination, (a) the rights and licenses granted to you in these terms will end; (b) you must stop using the app, and (if needed) delete it from your device. The developer it is not also responsible if any of the services result in malfunction after any update even though he will do his best to solve any bug you report as soon as possible.
5.1 The developer may update our Terms and Conditions from time to time. Thus, you are advised to review this page periodically for any changes. I will notify you of any changes by posting the new Terms and Conditions on this page. These changes are effective immediately after they are posted on this page.
If you have any questions or suggestions about my Terms and Conditions, do not hesitate to contact us.
