Terms of Use

This is an English translation of the original Japanese document, provided for convenience. If there is any discrepancy between the two, the Japanese version prevails.

These Terms of Use (these “Terms”) set forth the conditions for the use of the sleep app “Sleepa” (the “App”) provided by Medisense Inc. (the “Company”) and of the Company’s website (https://medisense-inc.co.jp/; the “Website”; the App and the Website are collectively referred to as the “Services”). Persons who use the Services (“Users”) shall use the Services after agreeing to these Terms.

  2. Explanations and rules regarding use that the Company posts on the Services (including the Privacy Policy) constitute part of these Terms.

Article 2 (Content of the App)

  1. The App reads sleep and other data measured by Apple Watch and stored in Apple’s Health app, and presents sleep trends by means of graphs, scores, explanations by AI, and the like.
  2. Use of the App requires a compatible iPhone and Apple Watch. Explanations by AI and answers to questions are available on iPhones that support Apple Intelligence. On other iPhones, the results are displayed as ordinary text.

Article 3 (Medical Notice)

  1. The App is not a medical device and is not intended for the diagnosis, treatment or prevention of any disease.
