If you are a Doudian store owner, you can hide your store data in the following ways:

1. Set store privacy permissions: In the "Settings" of the Doudian backend, you can set the privacy permissions of the store and select "Visible only to myself" or "Visible only to followers" so that other people cannot see your store data.

2. Close the store: If you don't want anyone to see your store data, you can close the store directly so that others cannot access your store.

3. Delete the store: If you want to completely delete the store data, you can select "Delete store" in the "Settings" of the Doudian backend, so that all store data will be deleted and cannot be restored.

It should be noted that the above methods will affect the exposure and promotion effect of your store, and it is recommended to use them when necessary.
