1. Scope

1.1 These Terms of Use (“ToU”) apply to the download and use of our App. Johns Hopkins has contracted with Mimi to develop the Hearing Number App. The App is a mobile application which enables iOS and Android users (“user” or “you”) to learn their Hearing Number, which is also known as the 4-frequency pure tone average, or PTA4, by taking a hearing test. Measurement of the Hearing Number with this App meets ANSI/CTA-2118 (Four Frequency Pure Tone Average Testing Methodology and Hearing Wellness Reporting Metric for Consumer-Facing Hearing Solutions). This standard describes the assessment and use of the PTA4 as a common hearing metric for consumer-facing devices in order to establish consistent terminology around hearing wellness and promote awareness of hearing wellness across the life course. 

After completing the test, you will receive a personalized result about your hearing. If you have taken multiple hearing tests over time, you can access all previous assessments from your Results History. 

1.2 These ToU apply if you download and use the App as a consumer, i.e. for purposes outside your commercial or professional activity. 

2. Terms of use, ordering process, conclusion of contract

2.1 The contract of use between you and us is concluded by using the App. The App can be downloaded and used free of charge. The use of the App, particularly the performance of hearing tests, is offered to you without registration or account creation. 

2.2 You should be at least 18 years old to use the App. Minors require the consent of their parents or legal guardians. 

2.3 To use the App, you need a mobile device, i.e. a smartphone or tablet, with iOS 16.4 or higher OS compatibility or with Android 7 or higher compatibility (API Level 24). The App can be downloaded from the Apple App Store for iPhone or iPad or Google Play for Google or Samsung smartphone or tablet.

2.4 After you have downloaded and installed the App on your device, you will have the opportunity to read the ToU. If you are asked separately to confirm that you have read and accepted the ToU, you cannot use the App without confirmation (e.g. by checking or ticking a box).

2.5 If necessary and in connection with the use of the App, we may also ask you for your consent to data protection.

2.6 We do not store the text of the version of our ToU in force at the time you downloaded the App. If you want to keep a copy of this version, please download it during the installation process.

Indirect damages and consequential damages resulting from defects in the App are also only eligible for compensation if such damages are typically to be expected.

    • in the event of willful or grossly negligent conduct;
    • in the event of death or personal injury;
