Privacy Policy

Hi! Thanks for using our app. We know you value your privacy, so this privacy policy explains in detail what information we collect from you and how we use it.

To help you find the information you’re looking for, you can click on any of the links below to jump to the relevant section of this privacy policy.



What our app does and why it needs your information

The Eveline App uses a discreet clip-on attachment for your phone to hold test strips in front of the camera, where the Eveline App automatically measures the hormone concentration and displays the test result on the screen of phone. The Eveline App tracks the previous results and your record to discover the personal biological rhythm, giving a heads-up of upcoming fertile days on the Fertility Calendar. The Eveline App also reminds you of upcoming tests and fertile days by sending notifications.

In order to provide those services, it needs certain information from you, and without that information our app wouldn’t work. For example, if we didn’t know the data of your menstrual cycle, we wouldn’t be able to send you notifications of upcoming tests and fertile days.

    In addition to the personal information you provide voluntarily, we also collect certain other personal information automatically when you use our app. This includes LH test results (test time, test result (peak/high/low), error images, user interaction, etc. We use this information for analytical purposes to understand how our users interact with our services, and to personalize your experience of our app.

This includes your device’s Language & Region, OS version, app version, device model name, etc. We may only be able to collect some of this information if your device settings allow it, so you should always review your app settings under your device’s settings menu to select what information you are happy for apps like ours to access or not to access.

    Who else sees your information

    To provide this app and our service to you, we work with certain third party service providers. These service providers will have access to your information for the purposes described in this privacy policy, and we require them to protect it in accordance with the standards set out in this privacy policy.

    In addition, we may also disclose your information to law enforcement, competent government authorities and other third parties where we believe are required to do so by applicable law or regulation (including a court order), or where we believe disclosure is necessary to exercise, establish or defend legal rights or to protect the vital interests of any person.

    How we keep your information secure

    We use appropriate technical and organizational measures to keep the information we collect about you secure at all times

    Data security is an evolving risk, and so we regularly monitor the threats to data and adjust our security measures as appropriate to adapt to these. However, you should understand that no organization or its systems can ever be guaranteed 100% secure all the time, and so should only share online or through mobile apps personal information which you are comfortable sharing acknowledging this risk.

    Where your information gets sent

    We’re headquartered in Taiwan. However, your data will be stored on servers located in Ireland. That means that if you use our app your information will get transferred to Ireland for processing. In addition, our service providers are based in various countries around the world including Taiwan, Ireland, the US and Japan, and your information will also get transferred to these countries for the purposes described in this privacy policy.

    Don’t worry though – even if these countries do not have data protection laws that are equivalent to the country in which you reside, your personal information will continue to be protected in accordance with this policy.

    Our use of tracking technologies

    Like other app providers, we also track our users’ use of our app. We do this for our analytics purposes so that we can understand how users interact with our app in order to help refine our app. If you wish to refuse all tracking for these purposes, or to reset your tracking history, please refuse tracking or reset your device identifiers (which will reset any prior tracking history) through the settings menus on your device.

    Retention Period

    We retain personal information we collect from you where we have an ongoing legitimate business need to do so (for example, to provide you with a service you have requested or to comply with applicable legal, tax or accounting requirements).

    When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize it or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.
