Privacy Policy — Amaterasu

Effective: September 30, 2026

Amaterasu is a guided breathwork app by Andres Arroyo. Your privacy matters, so here is the whole policy in plain language:

We collect nothing

Amaterasu does not collect, transmit, store on any server, sell, or share any personal data. The app works fully offline and contains no analytics, no tracking, no advertising, no accounts, and no network requests of any kind.

Your session history stays on your device

Your practice history (session dates, rounds, and retention times) is stored only on your iPhone, in the app's private on-device database. It never leaves your device. You can delete individual sessions from the History tab, delete all history from Settings, or remove everything at once by deleting the app.

Sharing is your choice

The optional Share feature renders a progress image on your device and hands it to the iOS share sheet. Nothing is uploaded by the app — what you do with the image from the share sheet is up to you and governed by the privacy policies of the apps you choose.

Children

Amaterasu is not directed at children under 13, and we collect no data from anyone.

Changes

If this policy ever changes, the updated version will be posted here with a new effective date.
