ZWHSmartLock Support

For the international app with email accounts and shared lock access.

Updated: October 21, 2026

Request account and data deletion

You can request deletion without installing or signing in to ZWHSmartLock. Email zhongwuhe2026@gmail.com with the subject ZWHSmartLock account and data deletion. You can copy the address and subject into any email service.

If possible, send from the email registered to your account. Identify the registered email and whether you request account deletion, deletion of associated data such as feedback pictures, or both. If you cannot access that email or the app, explain this in your request. Support reviews requests manually and verifies account ownership before acting. Never send your email password, account or lock management password, verification code, help word or Bluetooth authorization code.

You can start from Account → Delete account. Account deletion currently requires manual review; use the email instructions above to request account and associated-data deletion. Transfer or unbind locks you own first. Sending a request or obtaining a verification code does not mean the account, sessions, lock access, feedback pictures, authorization history or operation records have been deleted. Support verifies ownership and checks shared accounts and files before acting, then explains the completed actions and any information that must be retained. Until completion is confirmed, the app keeps local recovery data. See the Privacy Policy for details.

Use the app's Feedback page to submit a problem and optional pictures. Include the app version, phone model, lock model and the time of the issue. Never include passwords, verification codes or Bluetooth authorization codes.

Account or email code

New registration and normal sign-in both use an email verification code, without setting an account password. Check the email spelling and spam folder. Wait at least 60 seconds before requesting another code; codes expire after 10 minutes. An older account needs its original password once, together with an email code, when first verifying ownership. Do not create another account to bypass an ownership problem.

Bluetooth and control

Allow Bluetooth, wake the lock and stay nearby. Disconnect other phones using the device. If a command's result is uncertain, reconnect and read current status before trying another command. Check the battery and hardware instructions.

Shared access

The owner authorizes an email directly, with separate lock/unlock permissions and a validity period. No invitation notification is sent and no acceptance or manual claiming is required. Verify the same email when registering or signing in, or refresh the lock list while online, to receive matching access automatically. An unmatched or unverified email does not provide usable lock access. Contact the owner if authorization has expired, is frozen or has been revoked.

Language

The app starts in English. Choose English or 简体中文 on the sign-in or Account screen; your preference is saved on this device. Manufacturer-provided pictures, videos and documents retain the language supplied by their provider.
