How can we help?
Find quick answers for sign-in, ring connection, data sync, notifications, and ring benefits. You can contact us directly if the steps below do not resolve the issue.
Contact support
Email florencem@changyi.homes and include your phone model, system version, app version, and a short description. Do not send verification codes, raw sensor files, or sensitive photos by email.
Sign-in
Select your country or region first; the app adds the dialing code automatically. Enter a phone number you are entitled to use, request the SMS code, and then sign in. Guest mode remains available for supported local ring features.
Ring connection
Charge the ring, keep it near the phone, turn on Bluetooth, and allow the Bluetooth or Nearby Devices permission. A previously bound ring reconnects automatically when available. To use another ring, open Ring & Sync and choose Change Ring.
Sync and history
Heart rate, steps, and sleep can be viewed from the app’s local history without signing in after the ring has supplied those records. Cloud trends require sign-in and your separate cloud-sync choice. Keep the app open briefly after reconnecting if the ring has accumulated records.
Notifications
System permission and the in-app reminder switch are separate choices. You can change proactive reminders in Knowledge Space and system notification permission in your phone settings. Notification previews do not contain detailed wellness readings.
Membership and ring benefits
Today’s Charm and Ask require an active membership. Monthly and yearly memberships and one-time allowance packs can be purchased through the app store on your device. Membership subscriptions renew automatically unless canceled in the system subscription settings; allowance packs do not auto-renew. Store pricing and purchase terms are shown before confirmation.
After hardware verification, each eligible physical ring provides one lifetime membership. A second ring does not add a second membership, and each physical ring can be claimed only once across accounts and devices.
Account and privacy
You can delete your account in Me → Delete Account and Records. Account deletion does not automatically cancel an Apple or Google Play subscription; cancel it separately in the corresponding store subscription settings. The public pages below explain the deletion process, data use, system permissions, and the non-medical product boundary.
