echoPi app — Privacy Policy

Effective: October 4, 2026

The echoPi app is provided by Shanghai Hantian Chenyi Technology Co., Ltd. ("we").

We don't collect your data. This version of the app has no account and doesn't connect to the internet. Your creations, settings and play-along records are stored only on your phone, in the app's private storage. Deleting the app deletes them.

We don't use advertising or analytics tools, and we don't track you across apps or websites.

The app uses your phone's vibration and speaker to preview feels and sounds. It does not use your camera, location, contacts, Bluetooth or any other personal data in this version.

If a future version adds online features (such as sharing, or connecting to echoPi), we'll update this policy and ask you before anything leaves your phone.

Children: the app collects no personal information from anyone, including children.
