Dim

About Dim

Dim is a private migraine diary made by Arve Tech. It is designed to help people record attacks quickly and bring a clearer history to a clinician.

Why Dim exists

Migraine records are most useful when they are consistent, but logging during an attack is difficult. Dim focuses on a quiet interface, fast capture, useful context and reports that remain under the user's control.

Privacy by design

Dim does not require an account and does not sell health information. App health history stays on the user's device and personal iCloud. The website weather tool sends approximate coordinates directly from the browser to Open-Meteo; Dim does not receive or store them.

Medical boundaries

Dim is a diary, not a medical device. It does not diagnose, predict, treat or prevent migraine. Website content is general information and is not a substitute for individual care.
