Contact

Last updated: August 17, 2026

A question, a suggestion, a bug, or you want your data deleted and cannot find where — just tell us. There is a support entry right inside the app.

Contact support in the app (fastest)

Open mythings and go to “Me → Contact Support”; it takes you straight to a WeChat support chat, no need to add a friend. On the “Me → My Account” screen, tap “User ID” to copy it and send it along — it helps us find your account faster.

Open the support chat in WeChat

Email

yanwave@qq.com — usually answered within one or two business days. Including your user ID, the app version (at the bottom of the “Me” tab) and a screenshot makes it much faster.

Write to yanwave@qq.com

Export, deletion and account deletion

You can do all of these yourself in the app: export from “Me → Backup & Restore”, delete a single record from its detail screen, and delete your account at the bottom of the “Me → My Account” screen. If something goes wrong, or you want to know how we handle your personal information, read the Privacy Policy or reach out to support.
